Traditionally applied spontaneous fermentation was compared with the use of starter cultures to initiate fermentation after dry milling and sterilizing at 1210C for 10 minutes. Lactic acid bacteria (LAB) populations comprised 80% of the total viable bacteria and remained prominent throughout the fermentations, while number of moulds declined as the fermentation progressed. The fermentation meth...

We examined 62 strains and 21 trade starter cultures from the collection of LB Bulgaricum PLC for proteolytic and antimicrobial activity of lactic acid bacteria (LAB) grown in goat milk. The aim of this study was to investigate the fermentation of caseins, α-lactalbumin and β-lactoglobulin by LAB, using the o-phthaldialdehyde (OPA) spectrophotometric assay and sodium dodecyl sulphate polyacryla...

The influence of indigenous starter cultures on the free fatty acids content during ripening of »salsiccia«, a typical dry fermented sausage produced in the Basilicata region, was studied. Three batches of »salsiccia« were produced using different starter mixtures (Lactobacillus sakei G20 and Staphylococcus xylosus S81; L. sakei G20 and S. xylosus S142; L. sakei G20 and S. xylosus S206), while ...

The use of selected starter culture is widely diffused in winemaking. In pure fermentation, the ability of inoculated Saccharomyces cerevisiae to suppress the wild microflora is one of the most important feature determining the starter ability to dominate the process. Since the wine is the result of the interaction of several yeast species and strains, many studies are available on the effect o...

North-East India is inhabited by many indigenous tribes and as a part of their socio-cultural life most of these tribes prepare their own local brew, mostly using rice grains as the substrate. In addition each of the tribes also prepares their own unique starter cultures to carry out fermentation, and each type is a mixture of different parts of various plant species. These starter cultures in ...

Benzoic acid is occasionally used as a raw material supplement in food products and is sometimes generated during the fermentation process. In this study, the production of naturally occurring yogurt preservatives was investigated for various starter cultures and incubation temperatures, and considered food regulations. Streptococcus thermophilus, Lactobacillus acidophilus, Lactobacillus delbru...

It has been observed that Lactobacillus acidophilus has poor survivability in fermented goats’ milk. In this study, interactions between L. acidophilus and starter cultures during goats’ milk fermentation were investigated using three strains of L. acidophilus: ATCC-11975, LA-5 and NCFM, and the starter cultures (Lactobacillus delbrueckii subsp. bulgaricus (LB350) and Streptococcus thermophilus...

Fermented dairy products have long been an important component of nutritional diet. Historically, fermentation process involved unpredictable and slow souring of milk caused by the organisms inherently present in milk. However, modern microbiological processes have resulted in the production of different fermented milk products of higher nutritional value under controlled conditions. These prod...

In this study, the effects of proteolytic activity of yogurt starter bacteria on physicochemical and technological properties of yogurt were investigated. Moreover, impact of proteolytic activity and production of exopolysaccharide (EPS) on the performance of each strain were screened. In order to compare the textural properties of yogurt samples, four parameters were evaluated: syneresis, wate...
