The objective of this study was to determine the effect of colostrum on microbial populations of yogurt and kefir. For this purpose, raw bovine colostrum is freeze-dried and added to yogurt and kefir on 8% and 16% (w/w; colostrum/product) dilutions. The results showed that, effect of colostrum on total mesophilic aerobic bacteria counts of yogurt and kefir are negligible. Streptococcus thermoph...

Food allergy is now recognized as a worldwide problem, and like other atopic disorders its incidence appears to be increasing. Kefir is reported to possess the ability to reduce intestinal permeation of food antigens; however, no experimental study has clearly evaluated the relationships between kefir consumption, allergenspecific IgE response, and intestinal microflora. The aim of this study w...

Cheese whey (CW) is the liquid by-product of cheese and yogurt making. This potential pollutant has high-quality nutrients exploitable through fermentation processes. Using high-intensity ultrasound on dairy products shown several technological advantages for bioprocesses. Therefore, this study aimed to investigate effect (HIUS) kefir grains biomass increase specific metabolites in CW kefir. Fr...

Introduction Kefir grains with efficient proteolytic system is an excellent starter culture for the production of bioactive peptides and milk products. This study explores casein derived from fermented bovine by kefir using peptidomics approaches. The angiotensin converting enzyme (ACE) inhibitory activity these were also investigated. Methods After fermentation, based on LC-MS/MS was used to i...
