The invention is directed to a lactose-positive, galactose-negative, Streptococcus thermophilus strain releasing glucose during milk fermentation. This Streptococcus thermophilus strain carries mutation in the glcK gene, in the ccpA gene, in the lacZ gene and/or in the ptsH gene, and optionally in one or more genes, in particular one gene, encoding a protein of the mannose-glucose-specific PTS. The invention also concerns a composition comprising at least one, lactose-positive, galactose-negative, Streptococcus thermophilus strain of the invention, and the use of this strain or composition to manufacture a fermented dairy product.

By a method for producing a culture for obtaining a culture by culturing a lactic acid bacterium and/or a bacterium belonging to the genus Bifidobacterium in a milk peptide-containing medium which is characterized in that a culture temperature is 3° C. or more lower than an optimum culture temperature of the lactic acid bacterium and/or the bacterium belonging to the genus Bifidobacterium, the change in the acidity during the storage of the product is not accelerated, and the bacterial count at the time of the preparation of the product can be maintained at a high level, even when the lactic acid bacterium or the like is cultured in a medium containing a milk peptide added thereto.

Disclosed is a composition for promoting absorption of a poorly water-soluble phytochemical which can significantly improve the intake of a phytochemical into a body, especially a migration speed and/or a migration amount of the phytochemical into a blood. A polysaccharide-containing lactic acid bacterial product, which is produced by Lactobacillus delbrueckii ssp. bulgaricus OLL1251, can significantly enhance the intake of a phytochemical into a body, especially a migration speed and/or a migration amount of the phytochemical into a blood. Thus, the composition for promoting absorption of a phytochemical according to the present invention includes, as an active ingredient, the polysaccharide-containing lactic acid bacterial product. Furthermore, the composition for promoting absorption of a phytochemical is useful as a food additive composition. In addition, a food, or a beverage, or a food or beverage composition to which the composition for promoting absorption of a phytochemical is added can obtain an effect of promoting absorption of phytochemical.

The invention relates to preparation of fermented food products, including dairy or dairy analogue products, with Pichia kluyveri and lactic acid bacteria in the presence of carbohydrate(s) which is sucrose, fructose, glucose or mixtures thereof. Fermentation of such products can be made using a starter culture composition comprising Pichia kluyveri strain(s) and lactic acid bacteria strain(s). The composition optionally comprises carbohydrate(s) which is sucrose, fructose and/or glucose.

The present invention relates to a lactic acid bacterium, in particular a strain of the Streptococcus genus, with reduced sensitivity to cos-type bacteriophages. The invention also relates to methods to engineer these lactic acid bacteria as well as their use to ferment milk.

A nutraceutical formulation used to unblock receptors is disclosed herein. The nutraceutical formulation used to therapeutically treat humans includes arachidonic acid, docosahexaenoic acid (DHA), echinacea, kaempferol, coffee fruit, and probiotics.

The present invention is a yogurt product that may be consumed by dogs and other mammalian pets. The yogurt product is in an unflavored form comprising as essential constituents: (A) 0% to 88% by weight water; (B) 0.2% to 25% by weight of a no-fat protein component selected from the group consisting of skim milk and cultured skim milk; (C1) 0.001% to 6% by weight sugar component comprising: (C1) 0.001% to 6% polydextrose and (C2) 0.001% to 6% Glycoses and Galactoses; (D) 2% to 8% by weight milk derived solids; (E) 0.2% to 2.5% by weight stabilizers and emulsifiers; and (F) at least one probiotic microorganism. The yogurt product may be refrigerated and served as a mousse, frozen dessert, or as a fermented yogurt drink similar to Ayran or Kefir. A method for producing the yogurt product is also disclosed herein.

The present invention is directed to a method of producing a Streptococcus thermophilus strain comprising the steps of a) Providing a mother strain in the form of Streptococcus thermophilus DSM32502, b) Growing a culture of the mother strain in the presence of a bacteriophage, to which the mother strain is not resistant, to obtain a number of mutant strains, which are resistant to the said bacteriophage, c) Measuring the acidification time of the bacteriophage-resistant mutant strains and the mother strain in a milk base and selecting at least one mutant strain with a reduced acidification time as compared to the mother strain to obtain a fast-acidifying mutant strain.

The present invention discloses a novel probiotic fermented beverage based on whey, comprising whey and a high probiotic microorganism concentration in the range of 10.sup.7-10.sup.8 CFU/mL, and a method for producing said beverage. The probiotic microorganism is a commercial yogurt culture of Streptococcus salivarus subsp. thermophilus and Lactobacillus delbruecki subsp. bulgaricus and a commercial culture of Lactobacillus acidophilus. The method for producing the probiotic fermented whey based beverage comprises recovering whey by an enzymatic coagulation process, percolation, enriching and pasteurizing whey, fermentation, sweeting and flavoring. The beverage comprises the following physico-chemical characteristics: pH 5.0±0.00; titratable acidity 68.0±1.4 mL NaOH 0.1N/100 mL; total solids 12.4±0.1% w/v; fat 0.8±0.1% w/v; protein 1±0.1% w/v; cinder 0.55±0.02% w/v; Total sugar 10.0±0.2% w/v; Reducing sugar 4.20±0.15% w/v; and Energic value 87.2±0.00 cal/100 g sample. The beverage comprises the following physico-chemical characteristics and probiotics count at 4° C. and 8° C.: 1-21 day shelf-life; pH 4.77-4.85; titratable acidity 72-73 mL NaOH 0.1N/100 mL; and probiotic count of about 31×10.sup.7-39×10.sup.7 CFU/mL.

The invention relates to a lactose-positive, galactose-negative, Streptococcus thermophilus strain carrying a mutation in 2 or 3 genes selected from the group consisting of 1) a gene encoding a protein of the mannose-glucose-specific PTS and a glcK gene, 2) a gene encoding a protein of the mannose-glucose-specific PTS and a ccpA gene, and 3) a gene encoding a protein of the mannose-glucose-specific PTS, a glcK gene and a ccpA gene, wherein said strain, when used to ferment milk, provides a low lactose fermented milk and/or a fermented milk not undergoing acidification when stored at fermentation temperature.
