摘要:
Provided are a production method for an edible fermented dairy product using, as a raw material, sterile full fat soy flour, which has a very high nutritional value and has a markedly improved taste evaluation that includes flavor and smooth texture, and a fermented dairy product produced by the method. A production method for a fermented dairy product includes the steps of: producing sterile full fat soy flour having a grain size of from 100 to 1,000 meshes by pulverizing sterile dehulled soybeans prepared so as to have a bacterial count of 300 cells/g or less by using a method of separating whole soybeans into cotyledons, germs, and hulls; adding water to the sterile full fat soy flour to prepare a powdered soy juice, followed by sterilizing the powdered soy juice by heating; homogenizing the powdered soy juice to prepare a homogenized powdered soy juice; and adding a lactic acid bacterium to the homogenized powdered soy juice, followed by fermentation to prepare fermented milk.
摘要:
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.
摘要:
A method for imparting phage resistance to phage sensitive strains of Streptococcus group N is described. The method involves transferring plasmid encoding for production of a mucoid substance (Muc.sup.+) into the phage sensitive strain. Even if the Muc.sup.+ plasmid is removed by curing at elevated temperatures the strains remain resistant to phage. The resulting resistant strains are novel and are used for fermentations, particularly milk fermentations.
摘要:
A lactose-fermenting (Lac.sup.+), mucoid (Muc.sup.+) Streptococcus lactis transconjugant designated ML-3/2.230 was obtained by conjugative co-transfer of Lac.sup.+ Muc.sup.+ phenotypes from Lac.sup.+ Muc.sup.+ Streptococcus cremoris MS to lactose-negative (Lac.sup.-), non-mucoid S. lactis ML-3/2.2. Curing studies on the transconjugant ML-3/2.230 showed that Muc.sup.+ phenotype in the strain was encoded on two plasmids, pSRQ2203 and pSRQ2204. DNA hybridization experiments also indicated the involvement of two plasmids in the expression of the mucoid phenotype. Plasmid pSRQ2203 also contained genetic information for lactose utilization (Lac.sup.+).

摘要:
Novel cultured buttermilk compositions made by fermentation of a fermentation mixture comprising about 15 percent to about 70 percent fresh cowmilk, ewemilk or other suitable fresh milk and about 85 percent to about 30 percent soymilk using buttermilk fermentation organisms are provided. Use of a sweetener and a thickener is unnecessary to provide a cultured buttermilk composition having a good acceptability and like or substantially indistinguishable from that of a corresponding cultured buttermilk composition made from the fresh milk used in making the cultured buttermilk compositions. Flavoring agents and fruit preparations suitable as additives in preparation of cultured buttermilk compositions can be added in conventional manner. The provided compositions have an enhanced Protein Efficiency Ratio value of about 2.5 and a reduced animal fat content as compared to the corresponding compositions using 100 percent fresh milk. Also provided are methods of preparation of the novel cultured buttermilk compositions.
摘要:
The present disclosure relates to methods and compositions for preparing cheese products with exopolysaccharide (EPS). In particular, an EPS-producing culture is deactivated either before or shortly after combination of the EPS-fortified ingredient with a base milk ingredient, i.e. cheese milk. In many cases, the base milk ingredient is a low or reduced fat ingredient. The base milk ingredient may have an added fat. Also contemplated are cheese products made using the disclosed methods and compositions.
