A malolactic ferment is produced from at least one malolactic bacterium strain which is cultured in a culture medium containing an assimilable nitrogen source, malic acid and alcohol. The ferment biomass is separated from the culture medium. The biomass may be concentrated and may be frozen with a cryoprotective agent or dehydrated. The biomass may be added directly to wine to effect malolactic fermentation.

Preparation and use of a malolactic ferment biomass

An acidified milk product of creamy consistency obtained by acidification of a suspension of the skimmed milk type with a combination of roping and thickening lactic bacteria and showing high stability to hot coffee, to sterilization and in storage.

Acidified milk product of creamy consistency and process for making

Acid resistant bifidobacteria, particularly the strains Bifidobacterium infantis CNCM I-372, Bifidobacterium bifidum CNCM I-373 and Bifidobacterium breve CNCM I-374, are cultured in a semisynthetic or synthetic lactic medium. The culture compositions are resistant to oxygen and acid and have a survival level of at least 1:10 after 30 days at a pH of 4.0 at 5.degree. C. and thus are utilized in acidified food products, such as acidified milks and yogurts, having a pH of from 4.0 to 4.6.

Preparation of compositions including acid-resistant bifidobacteria

A soft, unripened cheese having a dry matter content of from 18 to 35%, of which at least 40% consists of the non-fat solids of milk. The cheese is prepared from concentrated milk by innoculating the milk with a culture of a combination of strains of thickening Streptococcus cremoris, strongly acidifying Streptococcus cremoris and mildly acidifying Streptococcus lactis.

Soft, unripened cheese

Yogurt having a reduced increase in acidity and bitterness during storage at ambient temperature is produced by fermenting milk with Streptococcus thermophilus and a Lactobacillus bulgaricus strain which has low proteolytic activity and allows a DNA-DNA hybridization of from 80 to 100%. A thickening strain of Streptococcus thermophilus may be used. The yogurt may be packed under sterile conditions and stored at about 20.degree. C.

Production of yogurt

A spreadable cheese having characteristics of crescenza cheese is prepared by coagulating milk with lactic acid at a pH of 5 to 5.3 to produce curd, draining the curd to a dry matter content of from 30 to 50%, adding salt to the drained curd in an amount of 0.5 to 1% of the total weight of the drained curd and allowing the salted curd to ripen until it is complete. By this process, it is possible to produce on an industrial scale a cheese having characteristics of the traditional crescenza cheese.

Spreadable cheese having characteristics of crescenza cheese

A microcapsule containing a microorganism. It contains a microorganism of the genus Lactobacillus and/or Bifidobacterium and/or other geni of the intestinal flora coated with a fat which is solid at body temperature.

Microcapsule containing a microorganism and a process for its production

A process for the production of a cheese in powder form which, after reconstitution, has the properties of mozzarella or of a cheese for souffles, which comprises inoculating a colloidal solution having at least partly the composition of a skimmed milk with a lactic ferment, allowing the solution to ferment under aerobic conditions until its pH falls to a value of from about 4.8 to 5.2, heating the fermented solution to obtain curds and serum, separating the curds from the serum, adding to the curds approximately 5 to 50% by weight, based on dry matter, of fats while adjusting the pH of the mixture if necessary to a value of from about 5.1 to 5.7, and drying the mixture obtained.

A rennet-like milk-curdling enzyme is obtained from the stomach tissue of poultry by immersing the tissue in an aqueous saline solution with a pH-value below 4, and thereafter separating out undissolved materials to leave a solution containing the enzyme.

Production of a milkcurdling enzyme

A process for preparing a butter-like dairy product, which comprises the steps of pasteurising a cream containing not more than 40% by weight of fat, centrifuging the pasteurised cream and recovering a concentrated cream containing 50 to 65% by weight of fat, adding skimmed milk in quantity such as to reduce the fat content of the final product to between 47 and 56%, heating the cream to a temperature not exceeding 93.degree.C in 5 to 60 seconds, adding 0.05 to 5.0% by weight of an acid substance in quantity such as to bring the pH of the final product to between 5.2 and 5.6, said temperature being such that immediately after acidification said cream is at at least 85.degree.C, said acid substance being selected from the group consisting of an acid culture of a microorganism producing a butter flavor and an edible acid in combination with a butter flavor, cooling the resulting mixture to a temperature between about 2.degree. and 10.degree.C and holding the product at this temperature for at least 24 hours.
