Tomas cheese is a kind of cheese that is still traditionally produced, and it is not widely-known. In this study, the characteristic properties of Tomas cheese, a local product that is extensively consumed in the city of Tunceli and its environs, have been examined. For this purpose, samples from cheese varieties currently on sale in the cities of Tunceli and Elazl~ have been taken, and some of their physico-chemical and microbiological properties have been determined. The results of physico-chemical analysis showed that the average moisture rate of the samples was 53.24%, average ash rate 4.24%, average dry matter 46.76%, average acidity rate in terms of lactic acid 1.08%, average salt rate 2.93%, average fat rate 17.66%, average fat-free dry matter rate 25.56% and average pH value 4.67. The microbiological analysis data showed that the average values for the total aerobic mesophyll bacteria (TAMB) was 7 loglo kob/g, 2.3 logl0 kob/g for coliform, 4.6 logl0 kob/g for yeast, 5.5 logl0 kob/g for mold, 6.8 log10 kob/g for Lactococcus spp., and 6.1 log10 kob/g for Lactobacillus spp.. The results show the high variation among samples, proving that there has not been a standard production procedure. It has been established that the hygienic condition of the product changes according to the production process, and the probability for cross contamination is high. A large number of studies need to be carded out for this kind of traditional food items, due to lack of enough literature data in this paper.展开更多

The amount of protein ranged from 9% to 14% in our analyzed set. The highest value had yellow variety of wheat BONA DEA (14%), at least had red grain of variety FEDERER (9.02%). Average content of fl-glucans determined by enzymatically ranged from 0.25% (BONA VITA) to 0.67% (ABISSINSKAJA and LUTEUS). The largest amount of phenolic compounds (134 mg GAE/L) and flavonoids (2.80 mg RE/L) contained sample RU440-6, the lowest sample was IS CORVINUS (87 mg GAE/L). The highest antioxidant activity was observed in blue varieties of wheat 48M (0.269 mmol TE/L), while the lowest was determined in a sample of purple ANK 28A (0.083 mmol TE/L). Data show that there is potential to use purple, blue and red variety of wheat as novel ingredient resources for the development of new innovative products. Assessment of the results we selected two varieties of color wheat (KONINI, RU440-6) in bakery attempt to meet demand for nutritional quality and also have an increased content of healthy components. Overall the most pleasant taste, color and flexibility bread crumb had a loaf of bread prepared from a purple variety KONINI without the addition of β-glucans.展开更多

It is especially the case of cheeses, whose taste varies from one geographical region to another depending on specific flora and technological processes used in traditional systems. The paper tries to bring new elements on the methodology used in order to elucidate some aspects related to traditional products' quality, products obtained by private producers in the Bra^ov district (Rucar-Bran pass). Covasna district and Bistrita Nasaud district were analyzed organoleptically, physico-chemically and microbiologically samples of fresh cow cheese, soft cow cheese, smoked curd cheese, gaiter cheese and cottage cheese taken within the strategic and self-control program from individuals in the rural areas of Fundata, Poiana Sibiului, Sirnea, Pfirliu, Cristian, Cincaor, Sohodol, Ranov, Brarov, Bod, Roadea, Harnan, Prejmer, Soars, Rupea, Lunca Calnicului, Balanii, Mari, Bran, Buzaiel, Bacut, H~.lchiu, Fagraa, Moeciu de Sus, Purcaareni, Bran-Simon, Venelia de Jos, Vama Buzatului, lntorsura Buzaului, Vatrghia and Sita Buzaului.展开更多

A plethora of research has been conducted to unravel the composition and dynamics of microbial consortia associated with Chinese traditional fermented foods using culture- dependent as well as culture-independent methods, like different high-throughput sequencing (HTS) techniques. These HTS techniques enable us to understand the relationship between a food product and its microbes to a greater extent than ever before. Considering the importance of Chinese traditional fermented products, the objective of this paper is to review the diversity and dynamics of microbiota in Chinese traditional fermented foods revealed by HTS approaches.展开更多
