Evaluation of sensory properties and their correlation coefficients with physico-chemical indices in Turkish set-type yoghurts

Sensory properties and physico-chemical parameters of 10 most popular brands of commercial set-type Turkish yoghurts were evaluated and correlation coefficients between the two indices were investigated. The results indicated that increases in volatile compounds (acetaldehyde, 2-butanone, 2-nanonane, ethyl acetate), titratable acidity, ash and fat contents inversely correlated with the overall acceptability score of the yoghurt. However, diacetyl, C4 to C12 free fatty acids, pH, whiteness index and texture positively correlated with overall acceptability of the yoghurt products. It was concluded that the acceptability of the Turkish set-type yoghurts is mainly governed by the fifteen volatile compounds as well as the physico-chemical properties determined. Thus, the overall acceptability of the yoghurts was not influenced by a single characteristic, but rather by complex in nature.

Characteristics of physico-chemical properties, volatile compounds and free fatty acid profiles of commercial set-type Turkish yoghurts

Ten most popular brands of commercial Turkish set-type yoghurts were collected from local retail outlets in Hatay, Turkey for two separate periods, and analyzed for basic nutrients, physico-chemical properties, volatile aroma compounds and free fatty acid profiles to compare their differences among the yoghurt products. The results showed that there were significant differences (P<0.05, 0.01, or 0.001) and variations in physico-chemical indices, volatile aroma compounds and volatile free fatty acid profiles among the yoghurt brands, which ultimately influence the flavor quality of the product. Acetaldehyde was predominant volatile compound in yoghurts, which followed by acetone, acetoin, diacetyl and ethanol. The level of diacetly was inversely related to titratable acidity, acetaldehyde and ethanoic acid. From ketones with high carbones 2-undecanone and 2-pentadecanone were higher than 2-butanone, 2-nanonane and 2-tridecanone. These ketones are related to fat content of yoghurt. Among short chain free fatty acids, ethanoic (acetic) acid was the most abundant in yoghurts, followed by hexanoic, octanoic and butanoic acids. These differences in detected chemical compositions of volatile compounds and free fatty acids would be applicable to predict flavor, nutritional value, quality control or shelf-life of the commmercial set-type Turkish yoghurts.

In vitro bioaccessibility of phenolic compounds and alpha-glucosidase inhibition activity in yoghurts enriched with mango peel powder

This study investigated the potential health benefits and functional properties of mango peel powder(MPP)as a source of antioxidants and alpha-glucosidase inhibitors in yoghurts with probiotic bacteria.The study involved plain yoghurt(PY,control),yoghurt fortified with 2%mango peel powder(MY),and yoghurt fortified with 2%MPP and 1%of each probiotic culture of L.casei,L.rhamnosus,B.lactis(MPY).Bioactive potential and individual polyphenols in the products were analysed before and after in vitro gastrointestinal digestion.Results showed that both MY(0.26±0.02 mg/g GAE)and MPY(0.28±0.04 mg/g GAE)had significantly(p≤0.05)higher phenolic contents than PY(0.17±0.02 mg/g GAE).Among the 15 quantified phenolic compounds,quercetin-3-rhamnoside was highest in MPP(432.86±11.02 mg/100g dry wt.),followed by MPY(47.97±1.20)and MY(34.44±2.76 mg/100g fresh wt.).The quantities of the major individual phenolic compounds declined significantly(p<0.05)in MPP only after gastric digestion,while remained stable in MY and MPY.There were significant(p≤0.05)increments inα-glucosidase inhibition activity(6.06%and 8.47%,in MY and MPY,respectively)post intestinal digestion.The LC-ESI-QTOF-MS/MS analysis of all the sample extracts(undigested and digested)identified a total of 108 phenolic metabolites including 33 phenolic acids,42 flavonoids,11 lignans,3 alkylphenols,4 coumarins,3 tyrosols,1 stilbene,2 xanthones,4 phenolic terpene,and 3 tyrosols,2 hydroxybenzoketones,1 hydroxybenzaldehyde and 2 other phenolic metabolites.This study provides scientific evidence for the utilization of MPP fortified yoghurts as functional food products.

The safety perspective of probiotic and non-probiotic yoghurts:a review

Effect of Butternut Squash (Cucurbita moschata) Seed Powder on the Chemical and Rheological Properties of Stirred Cultured Camel Milk and Yoghurt

Research shows that producing fermented camel milk is hard because of the milk’s inability to form a firm coagulum, attributed to low levels of κ-casein and ꞵ-lactoglobulin and the large casein micelle size, leading to a weak network of casein formation. In an effort to address this issue, researchers turned to corn starch as a thickening agent, discovering that a concentration of 2.0% effectively improved the viscosity and significantly reduced syneresis in stirred camel milk yoghurt and cultured camel milk. This study explores alternatives to corn starch, focusing on butternut squash seeds as a promising substitute due to their hydrocolloid composition. By incorporating butternut squash (Cucurbita moschata) seed powder (BSSP) as a thickening agent, this study aimed at enhancing the chemical and rheological properties of stirred camel milk yoghurt and cultured camel milk. Fermented camel milk was prepared using 4 litres of camel milk, 2% starter cultures (thermophilic culture for yoghurt and mesophilic aromatic culture for stirred cultured camel milk) and BSSP 0.0% (negative control), 0.4%, 0.8%, 1.2%, 1.6%, 2.0% mixed with 0.4% gelatin. 2.0% corn starch mixed with 0.4% gelatin was used as a standard for comparison. Results showed that increasing the BSSP level significantly (p < 0.05) decreased the moisture content while increasing the total solid content of stirred fermented camel milk products. There was an increase in ash content with an increase in BSSP levels. There was a significant (p < 0.05) reduction in the pH, with an increase in BSSP levels in stirred fermented camel milk samples. Increasing the concentration of BSSP from 0.4% to 2.0% resulted in a significant (p < 0.05) increase in viscosity and a reduction in syneresis of stirred camel milk yoghurt and stirred cultured camel milk samples. This study demonstrated that BSSP effectively enhances the viscosity, reduces syneresis and increases acidity in stirred fermented camel milk products during storage.

Incorporation of phenolic extracts from different by-products in yoghurts to create fortified and sustainable foods

This work aimed to study and compare the effect of the incorporation of agro-industrial by-products(chestnut shell,grapeseed,and pomegranate peel)into yoghurts to fortify them while assessing their potential to replace synthetic preservatives.From each by-product,phenolic extracts were obtained and characterized.All extracts demonstrated antioxidant and antibacterial properties,and the capacity to inhibitα-amylase.Chestnut shell extract stood out regarding antioxidant capacity,displaying values of 1128 and 972 mgT_(rolox•gextract)^(-1),for the assays with DPPH and ABTS,respectively.Ten yoghurts were produced(negative control,positive control with 0.1%of sorbic acid,two for each extract with 0.1%and 0.2%of extract,a mixture of extracts and a mixture of extracts with sorbic acid),and stored at 4℃.The incorporation of the extracts into the yoghurts maintained their physical-chemical properties and microbiological safety.The samples inhibited the growth of Escherichia coli and Staphylococcus aureus.Oxidative analysis proved that higher concentrations of extract had similar results to synthetic antioxidants.The results showed the viability to fortify yoghurts with the incorporation of by-product extracts,developing a value-added food.Furthermore,revealed the possibility of these extracts replacing synthetic preservatives and antioxidants.

Study on Honey Stirred Yoghurt

[Objective] In this study, the aim was to study the optimal formula and technique of honey stirred yoghurt. [Method] The optimum formula and production technique of the honey stirred yoghurt were confirmed by studying the effects of the additive amount of honey, the adding time of honey, thermal death point, the ho- mogenization pressure and stability test on the sensory quality of stirred yoghurt. [Result] The experiment showed that the fermentation temperature of the honey stirred yoghurt should not be too high, and it should be close to that of common yoghurt. In addition, the fermentation time should not be too long, because along with the extension of fermentation time, there would be abnormal smell in the yo- gurt. The optimum formula and production technique were as follows： the additive amount of honey, sugarcane and fermentation agent was respectively 3%; two-sec- tion homogeneous pressures of the fresh milk were I ： 70 MPa, I1：30 MPa; the thermal death point was 85 ℃ and the time was 10 min; the fermentation occurred at 42℃, and the fermentation of the products was stopped when the ultimate acidity was among 0.70%-0.75%. [Conclusion] The study could provide some refer- ences for the production and processing of honey stirred yoghurt.

Probiotics Bacteria from Egyptian Infants cause Cholesterol Removal in Media and Survive in Yoghurt

One of the most significant groups of probiotic organisms are the lactic acid bacteria, commonly used in fermented dairy products. In this study, cultures were isolated from two infants. After screening for the classic properties of probiotic organisms, four promising isolates were identified as two strains of Lactobacillus acidophilus (P106, P110), strain of Lactobacillus plantarum (P164) and Lactobacillus. pentosus (P191)which were tested for capability to remove cholesterol and to deconjugate sodium taurocholate from the culture medium. Results showed that a considerable variation existed among cultures in their growth viability in the presence of bile salt, deconjugation of sodium tauro-cholate and assimilation of cholesterol from the medium. All tested strains removed less cholesterol from the broth (ranged from 4.02-24.32%) compared to those grown in broth supplemented with 0.2% bile salts (from 29.02 to 45.3). Lactobacillus acidophilus P106 appeared to be more active in bile salt hydrolase compared to the other strains, and therefore, is regarded as a suitable candidate probiotic and adjunct culture.These strains were employed to make yo-ghurt and, in order to achieve a short production time;a two-stage fermentation procedure was used with Streptococ-cus thermophilus and Lactobacillus delbrueckii subsp. bulgaricus providing the rapid acidification. Storage trials at 4o C showed that the viability of the probiotic cultures was retained over 15 days.

Mixes of Carrot Juice and Some Fermented Dairy Products: Potentiality as Novel Functional Beverages

The present study aimed to formulate and evaluate yoghurt and Rayeb (Traditional Egyptian natural fermented milk) mixes with red and yellow carrot juices. Out of 16 different mixing ratios (Eight for yoghurt and eight for Rayeb), data indicated that the most significantly acceptable mixes as judged by panelists were: yoghurt-red carrot juice (3:1 v/v), yoghurt-yellow carrot juice (2:1 v/v), Rayeb-red carrot juice (2:1 v/v) and Rayeb-yellow carrot juice (4:1 v/v). The aforementioned mixes were further investigated versus their counterpart controls (yoghurt and Rayeb). It was obvious that the formulated mixes contained considerably higher concentrations of the bioactive components mainly, ascorbic acid and anthocyanins (red-carrot mixes) and β-carotene (yellow-carrot mixes) along with antioxidant activity (DMPD Radical Scavenging Activity) and higher counts of probiotic LAB, as compared to the controls.

Chemical, Nutritional, Rheological, and Organoleptical Characterizations of Stirred Pumpkin-Yoghurt

Pumpkin contains considerable amounts of bioactive compounds which hardly valorized in dairy products. This study aims to investigate the chemical, nutritional, rheological, and organoleptical properties of prepared stirred pumpkin-yoghurt. Stirred yoghurt with three different pumpkin varieties pulp [American (AP), Domestic (DP), and Indian (IP) pumpkin] at 15% was prepared and stored at 5°C ± 1°C up to 14 d. The chemical properties of yoghurts include protein, fat, crude fiber, and available carbohydrates were significantly affected by adding pumpkin without remarkable change in caloric value. Addition of pumpkin pulps decreased the pH and increased the acidity of stirred pumpkin-yoghurt significantly (P -1 in all stirred yoghurts after 1 d. After that, it was increased without notable effect of adding pumpkin pulps, and with slight simulation in LAB, growth was noticed in DP and IP yoghurts. Total phenolic compounds (TPC), total flavonoid (TF), total flavonols (TFL), carotenoids contents, and antioxidant capacity of pumpkin-yoghurts were significantly increased. Fortifying yoghurt with pumpkin pulp was associated with a statistically significant effect on sensory parameters such as flavor, color, and overall acceptability. Scores of AP yoghurt showed the highest score which significantly differed from CY. It is obviously showed that panelists were favored the prepared stirred pumpkin-yoghurt. Thus, it is recommended that adding pumpkin pulps increases yoghurt health benefits and could be scaled up further.

Biofunctionality of Probiotic Soy Yoghurt

Soybean provides health benefits such as reducing cardiovascular disease, reducing menopausal symptoms, weight loss, arthritis, diabetes, osteoporosis and brain function. It contains phytochemicals such as isoflavones, saponins, phytosterols that promote health benefits. Soy food products are perceived as healthy food and are considered an important part of the diet. More than 50% consumers in the USA agreed that soy foods are healthy foods. Soymilk is considered as a suitable economical substitute for cow’s milk and an ideal nutritional supplement for lactose-intolerant population and also considered cholesterol free product for cardiovascular disorders. Fermented soy milk is a good source of bioactive peptides such as anti-ACE, antioxidative, anti-cancer and immunomodulatory. Many fermented soy milk based products such as soy cheese, soymilk-kefir, soy yoghurt etc. are produced.

Isolation of Red Rose Anthocyanin Pigment and Its Application to Inhibit Lipid Oxidation in Yoghurt

Anthocyanin is a water soluble natural pigmen, which could be extracted from Red Rose. Color is an important factor to determine the quality of foods, so that the pigments isolation must be selected type of solvent for extraction process. Besides functioning as dyes, anthocyanins have a role as a good antioxidant, so it can be used to protect the fat content of fermented milk such as yoghurt. This experiment was to find out the effect of different solvent type on extraction pigment （aquadest： sitrat acid/lactic acid/sulfate acid/chloride acid） and to determine the effect of the addition of anthocyanins in protecting the fat content of yogurt on several levels addition. The research result showed that anthocyanin＇s pigment of red rose from petal flower＇s could be effective solvent extracted using lactic acid 0.02 M and increased fat stability of yoghurt. The anthocyanin pigment showed with HPLC analysis that pigment resulted TLC analysis at rite time 13.10 （as Cyanidin glucoside） and 22.61 （as Malvidin glucoside）. Yoghurt that given anthocyanin pigment has proven that fat content can be maintained its 86.7% （fat content with 2% pigment as such as 0.117% and without pigment 0.087%） after being stored for 6 days at cold and room temperature.

Antioxidant, Some Flavor Components, Microbiological and Microstructure Characteristics of Corn Milk Yoghurt

Corn milk is considered as a new innovation especially in the making of yoghurt based products. The present study was conducted to study antioxidants components such as (phenols compounds and DPPH scavenging activity), total volatile free fatty acids, microbiological and microstructure characteristics in yoghurt samples produced from two different ratios of buffalos and corn milk (70:30 coded A and 60:40 coded B) respectively. Results indicated that the increasing ratio of corn milk led to increase the content of phenolic components and DPPH scavenging activity. Total viable content decreased in samples (70:30 and 60:40). Streptococci and lactobacilli count decreased by the increase of corn milk in produced samples. Results also show that the trend of yeasts content was the opposite ones. Election microscopy examination revealed that adding corn milk to yoghurt had more smoothly and systematically distributed casein with a bit coarse structure less porosity in the network of casein. From these results could be concluded that adding 40% corn milk during processing of yoghurt is increasing the antioxidant activity and improves the microstructure as well.

Physicochemical and Organoleptic Characteristics of Manufactured Buffalo Milk Yoghurt Incorporated Soy and Corn Milks

Soy-corn-yoghurt is a fermented product that obtained from inoculation of yoghurt starter to soy corn milk. The present study was conducted to study the use of different ratios of soy corn milk and corn milk only with buffalo milk in the manufacture of yoghurt. Two experiments were carried out , the first experiment was 100 ml buffalo milk :soy corn milk ratios 90:10, 80:20, 70:30, 60:40 and 50:50 (w/w), the second was buffalo milk with Corn milk 90:10, 80:20, 70:30, 60:40, 50:50 and 40:60 respectively and 100% buffalo milk as control. Treatments were coded B1, C1, D1, E1 and F1 in the first experiment, while B2, C2, D2, E2, F2 and G2 for the second respectively. All treatments subjected to chemical and organoleptic assessment. It was found those pH, total protein, fat content were decreased with increasing the ratio of soy corn milk in the product. Also, increasing the ratio of corn milk led to decrease all the previously mentioned characteristics. Curd firmness values for yoghurt made from (70:30) coded D2 and (60:40) coded E1 were higher than that of other treatments. Results indicated that mixes of (50:50) coded F1, (60:40) coded E1 and mixes (90:10) coded B2, (80:20) coded C2 and (70:30) coded D2 had the highest sensory scores and chemical quality.

Optimization of a Tiger Nut-Based Yoghurt Formulation by Response Surface Methodology

Tiger nut is a comestible tuber which offers many under products such as yoghurt. The parameters influencing the quality of yoghurt being numerous, response surface methodology was used to optimize the formulation in order to reach a low intake of milk powder. The volume of tiger nut milk, mass milk powder and sugar mass are the factors monitored while the titratable acidity (AT), pH, dry soluble extract (ESS), ash, viscosity and color are the expected responses in these tests. The data are processed with a degree of confidence p < 0.05 associated with statistical analysis by the software Statgraphic Centurion XVI version 16.2.04. The different tests show that the factors have overall significant effects (p < 0.05) on the acidity, the ashes and the Whiteness index. The linear and quadratic factors of tiger nuts milk as well as those linears of the milk powder have significant effects (p < 0.05) on the pH and the ashes. The linear factors of milk powder have significant effects on DSE, AT and pH. The optimal formulation yielded a volume of tiger nut milk equal to 3.7 L/kg, a mass of powder milk of 63.4 g and 75 g of sugar for one kilogram of yogurt. With a desirability of 75%, this model is apt to explain the results and the experimental values fit with the predicted ones and are within the norms. The proximate analysis of optimal yoghurt formulation shows that fat and proteins contents are respectively 5.67% and 2.2%. Calcium, magnesium and potassium contents are respectively 160, 40 and 180 mg in 100 g of yoghurt.

Effect of Okra Pectin on the Sensory, Physicochemical and Microbial Quality of Yoghurt

The objective of this work was to investigate the effect of okra pectin from two genotypes (asha and agbagoma) on the physicochemical, sensory and microbial quality of yoghurt. Okra pectin concentrations (w/w pectin to milk powder ratios) of 0.2%, 0.4% and 0.6% were used in the yoghurt preparation and its water holding capacity, titratable acidity and pH were analyzed against a control (0.0% pectin) weekly for a month. Consumer acceptability tests for the yoghurt samples were carried out using 50 untrained panellists on a 7-point hedonic scale. Total aerobic microorganisms present in the most preferred samples were enumerated over a four-week period. Results indicated that samples containing 0.2% asha pectin were most preferred by panelists. Water holding capacity varied significantly with those containing asha pectin higher than agbagoma counterparts and the control. There was a decline in pH with increasing pectin concentration and over the storage period. Samples containing agbagoma pectin had lower pH (3.60 - 4.32) compared to samples containing asha pectin (4.22 - 4.45). Titratable acidity increased during the storage period and with increasing pectin concentration. After four weeks of storage at 4°C sample containing 0.2% agbagoma pectin had the least microbial count (7.6 × 105 ± 4.51 cfu/g), followed by the sample containing 0.2% asha pectin (2.4 × 107 ± 11.14 cfu/g) and the control (8.6 × 107 ± 5.57 cfu/g). The study revealed that addition of okra pectin at 0.2% improved the consumer acceptability of yoghurt and 0.2% agbagoma pectin inhibits the proliferation of aerobic microbes. Addition of okra pectin also improved the water holding capacity and reduced whey exudation.

Antioxidant Activities of Exopolysaccharides Produced by Lactic Acid Bacteria Isolated from Commercial Yoghurt Samples

An antioxidant is a substance that inhibits the oxidation of other molecules caused by free radicals. The inbuilt antioxidant systems possessed by living organisms are generally not enough to prevent them from oxidative damages and the uses of synthetic antioxidants also have some harmful effects. This study was aimed at evaluating the antioxidant activities of exopolysaccharides produced by lactic acid bacteria isolated from yoghurt. Lactic acid bacteria (LAB) were isolated from six different brands of commercially available yoghurt using deMan Rogosa Sharpe (MRS) agar. The LAB isolates were identified based on morphological and biochemical analyses and were screened for exopolysaccharide (EPS) production. The LAB isolates screened positive were used for EPS production in a liquid medium and the EPS produced were purified and quantified using standard methods. Antioxidant activities of the EPS were evaluated by determining the 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging activity, ferric ion reducing power, and total phenolic contents. Data obtained were analysed using Analysis of Variance. Total lactic acid bacterial count obtained from the yoghurt samples ranged from 0 - 3.9 × 104 CFU/mL with sample A (Fan Yoghurt) having the highest LAB count (3.9 × 104 CFU/mL). The isolated LAB and their incidence rate were Lactobacillus plantarum (25.49%), L. delbrueckii (19.61%), L. fermentum (15.69%), L. acidophilus (13.73%), Leuconostoc mesenteroides (11.76%), Lactococcus lactis (7.84%), and Lactobacillus casei (5.88%). Fifty-one out of the 64 LAB isolates were screened positive for EPS production and only six were able to produce substantial quantity of EPS ranging from 127.4 - 208.5 mg/L. The exopolysaccharides produced by L. fermentum had the highest DPPH radical scavenging activity (62.90%) while that of L. plantarum had the lowest (23.10%) at a concentration of 1000 μg/mL. Also, the EPS produced by L. fermentum recorded the highest ferric ion reducing power (12.89 mg AAE/mL) at 1000 μg/mL while that of L. plantarum had the lowest (5.62 mg AAE/mL). At 1000 μg/mL, the total phenolic contents of the EPS samples ranged from 1.41 - 1.58 mg GAE/mL, and the EPS produced by L. fermentum had the highest (1.58 mg GAE/mL) while those produced by L. paracasei had the lowest (1.41 mg GAE/mL). This study revealed that the exopolysaccharides produced by the LAB isolates showed high antioxidant activities with respect to their DPPH free radical scavenging activity, ferric ion reducing power and total phenolic contents.

Apricot Probiotic Drinking Yoghurt Supplied with Inulin and Oat Fiber

In this study, the effects of different amounts of inulin and oat fiber addition on the properties of apricot probiotic drinking yoghurt (APDY) were investigated. Seven different APDY was produced. Six of them were produced by the addition of 0.5%, 1% and 2% inulin (B, C, D) and oat fiber (E, F, G) and one of them was produced as control sample. Pasteurized apricot pureed and sugar (10%) was added to fermented milk beverage. APDYs were analysed 1, 7, 14 and 21 days after production. Addition of fiber to APDYs had significantly affected on the pH, titratable acidity, water holding capacity, S. thermophilus, L. acidophilus Bifidobacterium BB-12 counts, and sensorial properties of the samples (p L. acidophilus and Bifidobacterium BB-12 counts increase by the addition of fiber into samples.

Rare Case of Surviving Infant with Strawberry Yoghurt like Blood Diagnosed to Be Infantile Hypertriglyceridemia at 1 Month Old: A Case Report

Background: Hypertriglyceridemia in children means increased plasma fasting Triglyceride levels above the 95th percentile for age and sex. For children aged 0 to 9 years, a triglyceride level greater than or equal to 100 mg/dl is considered above the 95th percentile. Hypertriglyceridemia can be mild to borderline high, moderate to high, very high, severe and very severe (>2000 mg/dl). We present the case of a 1 month and 3 weeks old baby who presented with difficulty in breathing. It was accidentally found to have strawberry yoghurt like blood during phlebotomy, of which upon investigation had very high triglyceride levels of >2000 mg/dl. Case Presentation: 1 month and 3 weeks old female baby, admitted as referral from nearby health centre presenting with difficulty in breath, her blood sample was incidentally found to appear as strawberry yoghurt like. Clinically the infant had features suggestive of respiratory distress, with no other systemic abnormalities noted. Chest X-ray that was done had features of pneumonia. The working diagnosis on admission was Pneumonia, Electrolyte imbalance. The strawberry yoghurt like blood raised suspicions of hypertriglyceridemia. Our triglyceride levels in the infant were very high at 136 mmol/l (12,046 mg/dl). The patient was treated with IV antibiotics for pneumonia, electrolytes were corrected and Rosuvastatin was started. This patient improved remarkably and was discharged with Rosuvastatin. Lipid profile was followed up for 4 consecutive months in our outpatient clinic with a drastic drop in triglyceride and cholesterol. Conclusion: We report a case of infantile hypertriglyceridemia found accidentally during phlebotomy. Despite limited resource to evaluate further on primary cause of this condition as well as family’s poor economic status to seek further medical evaluation outside the country, this case report raises awareness on how to deal with this condition in a low resource setting. It also highlights the role of statins in the treatment of hypertriglyceridemia.
