ABSTRACT: Kefir is fermented milk that has a unique flavor because of acetaldehyde, diacetyl, acetoin and ethanol. The aim of this study was to evaluate flavor and aroma compounds present in kefir. Two types of starter (Christian Hansen and Sacco) and three levels of temperatures (30, 33 and 35oC) were used for the preparation of kefir samples. The samples were analyzed for acetaldehyde, diacet...

The elderly are characterized by immunosenescence which is accompanied by an increase in the incidence of infectious diseases, especially in the intestinal tract. There is evidence suggesting that certain probiotic organisms have immunomodulatory properties. Therefore, the effects of feeding fermented milk products on the intestinal mucosal immune response was examined in young and senescent ra...

BACKGROUND Sheep’s milk has a high content of total solids, which qualifies it as a very good raw material for the production of fermented milk drinks. Currently, there are commercially produced kefirs and yogurts from sheep’s milk in the countries of the Mediterranean region. The growing interest in the consumption of these products is justified not only by their taste merits, but ...

The present work aimed to produce Minas Frescal cheese with the replacement of commercial lactic culture by fermented kefir milk (FKM) and verify some its physicochemical characteristics, aiming mainly at development a new probiotic dairy product low production cost as compared use cultures. Kefir grains were added whole UHT 22ºC/24 hours in an incubator, after fermentation separated FKM was us...

Stability in gut ecosystems is an important area of study that impacts on the use of additives and is related with several pathologies. Kefir is a fermented milk drink made with a consortium of yeast and bacteria as a fermentation starter, of which the use as additive in companion and livestock animals has increased in the last few years. To investigate the effect of kefir milk on foregut and h...

Rheological, textural, and sensory properties of kefirs with inulin were analysed. Besides, the effect of skim milk powder (SMP) and milk fat substitution was examined by high performance (HP) and native inulin. One-third of SMP was substituted by native (IQ) or HP (TEX!, HPX) inulin. Hardness of kefir with IQ inulin was lower than that with HP inulins or pure SMP. Analysis of cohesiveness and ...
