Propriedades antimicrobianas do kefir
RESUMO: Os leites fermentados têm sido amplamente consumidos desde a Antiguidade e, atualmente, comercializados em todo o mundo. Kefir é um leite fermentado, ácido, levemente alcoólico, produzido artesanalmente a partir da fermentação do leite pelos grãos de kefir, os quais contêm uma população estável de micro-organismos. O processo fermentativo gera uma série de compostos que conferem sabor e aroma característicos ao kefir, além de substâncias bioativas, responsáveis por propriedades nutracêuticas. A utilização de micro-organismos ...

Changes in carbohydrate profile in kefir fermentation
A B S T R A C TThe changes in microbial growth, pH and lactic acid content of traditional kefir were determined during fermentation (0-18 h) and cold storage (4�C for 1-7 days). A high-performance liquid chromatographic method was used to detect the carbohydrates and possible naturally occurring galactooligosaccharides (GOS) and their changes during fermentation and storage. The microbial content (Lactobacillus spp., Lactococcus spp., Lactobacillus acidophilus, Bifidobacterium spp., and yeasts) increased during fermentation and ...

Changes in the Quality of Kefir Fortified with Anthocyanin-rich Juices during Storage
ABSTRACTChanges in sensorial, chemical and microbiological qualities of kefirs fortified with black carrot (KBCJ), black mulberry (KBMJ), pomegranate (KPJ), and strawberry (KSJ) juices at different concentrations (10, 25 and 50%, w/w) were monitored throughout storage at 4 °C for 12 weeks. The most preferred kefirs by the sensorial panel were KSJ and KPJ, followed by KBMJ and KBCJ. KBMJ was associated with the highest anthocyanin stability, followed by KPJ, KSJ, and KBCJ. Lactic acid [r=(−0.688)−...

Do production and storage affect the quality of green banana biomass?
A B S T R A C TThe consumption of green banana (GB) products is booming because of their nutritional and physiological benefits to human health. However, there have been no studies on the quality of these products after they areprocessed and stored. Therefore, this study aimed to investigate whether production and storage affect the sensory and physicochemical characteristics of green banana biomass (GBB). We performed microbiological tests (total coliforms, E. coli, Salmonella spp., aerobic psychrotrophic bacteria, ...

Health Benefits of Green Banana Consumption: A Systematic Review
Abstract: Despite the growing demand for green banana (GB) products, there is no review study regarding their potential health benefits. We aimed to compare the health benefits among different GB products by a systematic review. We researched six electronic databases (PubMed, EMBASE, Scopus, Science Direct, Web of Science, and Google Scholar) from inception to March 2019. We found 1009 articles in these databases. After duplicate removal, we screened 732 articles’ titles and abstracts, and selected 18 potentially relevant ...

A novel beer fermented by kefir enhances antiinflammatory and anti-ulcerogenic activities found isolated in its constituents
AB S T R A C TKefir grown in molasses was activated to ferment malt for the production of beer. As kefir and beer are known to exhibit some beneficial health properties, anti-inflammatory and anti-ulcerogenic activities of a beer made with kefir were assessed using rat paw edema and ethanol-induced gastric ulcer model, respectively. The polyphenol content presented in the beers was evaluated by HPLC, whereas serum cholesterol, triacylglycerol, HDL cholesterol, ALT, ...

Development of new non-dairy beverages from Mediterranean fruit juices fermented with water kefir microorganisms
a b s t r a c tThe aim of this work was to explore the use of several Mediterranean fruit juices as fermentable substrates to develop new non-dairy fermented beverages. Microbiological, chemical and sensory features of kefir-like beverages obtained after the fermentation of juices extracted from fruits cultivated in Sicily (southern Italy) with water kefir microorganisms were investigated. Results indicated that both lactic acid bacteria and yeasts were able to develop in the ...
