摘要:
A fresh plant juice and/or milk-based food product, comprising a stable concentration of live probiotics producing false tastes and/or gas in the initial matrix of the food product, characterized in that it contains from 1 to 20 g/l of a dietary protonated weak monoacid with a pH between 3 and 4, and a preparation method for such a food product.
摘要:
The use of at least one sulphur-containing amino acid, at a total concentration of about 5 to 75 mg/ml, in particular of about 5 to about 50 mg/l, in particular of about 5 to about 30 mg/l, in particular of about 5 to about 20 mg/l, in free form, for implementing a method for preparing a fermented food product fermented by ferments containing bifidobacteria, the food product has acceptable sensory properties, contains more than about 5×107, in particular more than about 108 bifidobacteria per gram of food product fermented for a shelf lifetime of at least 30 days, in particular a shelf lifetime of at least 35 days, and containing no more than 0.5% of yeast extract or of yeast autolysate.

摘要:
The invention concerns lactic acid bacteria strains wherein the phosphorylable histidine of the IIA domain of lactose permease is replaced by a non-phosphorylable amino acid. Said strains have a reduced post-acidification and are useful in particular for preparing fermented dairy products.
摘要:
The present invention relates to the production of variants of lactic bacteria stems that produce, under standard fermentation conditions, at least about 1.2 times more K2 vitamin than the starting lactic bacteria stems cultured in the same conditions. The invention further relates to a method for preparing food products, including fermented products and/or fresh diary products, enriched with K2 vitamin, and to the food products thus obtained.

摘要:
The invention relates to the use of mutants of L. casei having at least a mutation impairing the regulation of a carbon catabolite repression (CCR) mechanism involving the PTS protein HPr, for the preparation of a food product.The use of said mutants allows for instance to impart to said food products an improved texture and flavor, and/or a higher content in aroma compounds.

摘要:
The present invention relates to a method for increasing the amount of K2 vitamin obtained by culturing at least one stem of a lactic bacteria that produces K2 vitamin, wherein the culture of said stem is realized in resting-cells conditions so that the amount of K2 vitamin produced by the resting-cells culture is higher by a ratio of at least 1.2 to that obtained by the culture of said stem under standard fermentation conditions. The present invention also relates to the biomass obtained from the culture of a lactic bacteria producing K2 vitamin according to the above method. The invention further relates to a method for producing K2 vitamin, to a method for preparing food products, including fermented products and/or fresh diary products, enriched with K2 vitamin, and to the food products thus obtained.
