Sensorial Evaluation and Physical Chemical Characterization of a Beverage Based on Whey and β-Glucans as a Potential Prevention of Nonalcoholic Steatohepatitis

Whey and B-glucans are functional food ingredients that contribute to the prevention of non-communicable diseases. The objective of the study was to develop a functional beverage based on whey, B-glucans, and blackberry concentrate for the prevention of nonalcoholic steatohepatitis, determining its sensory, physicochemical, and nutritional qualities. The following phases were developed: 1) formulation with 75%, 85%, and 90% whey and 25%, 15%, and 10% blackberry concentrate, with a fixed amount of 0.243 g β-glucans in 100 ml;2) microbiological analysis to ensure the safety of the beverage;3) sensory analysis with untrained panelists to assess the degree of preference (appearance, color, odor, flavor, viscosity, acidity, sweetness), and general acceptance, with a seven-point hedonic scale to rate the level of acceptability;4) physicochemical and nutritional characterization of the beverage with the highest acceptance. An experimental design using complete random blocks was employed. Data analysis was performed with variance (ANDEVA) and mean DUNCAN separation at a 95% confidence level, using SAS®. A correlation study was conducted on acceptance analysis. A nutritional label was developed for the control beverage and the treatment with the highest acceptance. The formulation with 75% whey, 25% blackberry concentrate, and 0.243 g of β-glucan obtained the highest acceptance, with flavor and sweetness being the attributes that contributed to its acceptance. Nutritionally, the beverage with 80 cal, would be considered fortified with fiber (2 g), free of cholesterol, sodium, and saturated fat, according to the Central American Technical Regulation on Nutritional Labeling (Version 67.01.60:10). It is recommended that the effect of this beverage be measured to determine the benefits.

Are Functional Foods Marketed in Honduras a Healthy Option?

Background: Functional foods have been proposed as vehicles to prevent diseases in response to disease increase throughout the world. Methods: Descriptive cross-sectional study. The nutritional labeling of processed functional foods (PFF) commercially available in Honduras was examined to consider health benefits based on functionality according to the Central American Technical Regulation (CATR) and critical nutrient content according to the profile of the Panamerican Health Organization (PAHO). Results: Out of a national sample of 631 commercial processed foods (CPF), 144 were defined as functional;sweetened and flavored yogurts and cereal bars reached the highest proportions (70% and 66%) of products available in their respective categories. None of the categories was on average “low in calories” according to criteria of CATR;sweetened breakfast cereals were the most caloric (180 kcal) and only sweetened juices had “calorie free” products (15%). Prepared meat did not meet the criterion of “low cholesterol” even though all the products in this category were the reduced fat version of the original CPF. All categories of cereal-based products met the “source of dietary fiber” criteria and 64% of baked products were “high in dietary fiber”. More than 70% of PFF exceeded the sugar recommendation of the PAHO profile, mainly sweetened breakfast cereals (100%) and sweetened juices (93%). 49% of the products exceeded the sodium recommendation, particularly baked products (100%) and cheeses (86%);100% of the later exceeded the recommendation of total fats. More than 60% of products simultaneously exceeded between 2 and 3 of PAHO profile criteria;5% exceeded all the criteria and 4% met all the PAHO profile criteria. The average price of PFF was $2.34, while that of conventional products was $1.87;sweetened breakfast cereals were the most expensive ($3.49 and $3.28) and sweetened juices were the cheapest ($1.79 and $1.89) for both CPF and PFF. Conclusions: PFF marketed in Honduras have an excessive content of critical nutrients. These results demonstrate the need for a rigorous and mandatory regulation in the production, advertising and sale of functional and conventional processed foods.
