    Notes: Six defined strains of bacteriophage-insensitive Streptococcus cremoris, grown in whey-based starter media, were used over a period of 10 months to produce more than 2 million kg of Cheddar cheese on continuous cheesemaking equipment. Flavor development in this cheese was less than that in cheese made with conventional bulk starter. Proteolysis in the trichloracetic acid (TCA) soluble cheese fraction was less in cheese manufactured using S. cremoris compared to conventional bulk starter. Rheological properties were studied and the force-compression curves related to the age, composition and pH of the cheese. Pattern recognition techniques were used to analyze the multivariate data. The texture was affected by the mechanical process, moisture content and yield point of the cheese. Casein proteolysis, age, culture type and firmness were the most discriminating variables affecting maturity.

    Notes: A simpler and less expensive process than the process of Helbig et al. (1980) for preparation of a nonbitter, desalted milk hydrolysate is presented. Skim milk was hydrolyzed with Alcalase (subtilisin Carlsberg) at 50°C in 3 hr. The resin in OH form was added to milk batchwise to simultaneously raise the pH to 8.5 for optimum proteolysis and exchange the anions in milk which contributed to saltiness. These modifications resulted in a shorter hydrolysis time and a more economical resin regeneration than those of the Helbig process. The dried milk hydrolysate was added to soft drinks and fruit juices at solids concentrations up to 10% (3% protein) without adverse effects on their taste, color, viscosity and clarity.

    Notes: Summary In this study, a new technique for biomass determination was developed. Proteases were used to separate cells from the culture broth in skim milk whey permeate medium and the solubilization of casein was achieved 99% by elastase, 95% by pepsin and 90% by trypsin. Elastase was found to be efficient and reproducible for determining biomass in skim milk whey permeate medium.
