BIOCONVERSION OF INDUSTRIAL CELLULOSIC PULP MATERIALS

TO PROTEIN ENRICHED PRODUCT

Murray M. Young, Waterloo, Canada, assigned to University of Waterloo

An industrial cellulosic pulp material, such as wood pulp and paper stock, pulp sludges resulting from the manufacture of paper, coffee and sugar and starch-rich cellulosic materials, such as, bananas and root crops, is converted into a protein-enriched product having significant amounts of microbial biomass in the form of the fungus, Chaeto- mium cellulolyticum.

PROCESS FOR M A N U F A C T U R E OF CHEESE

David Hettinga, Robert Wargel, Richard Tripp, assigned to Kraft lnc

A process is provided for the manufacture of cheese and cheese like products from an edible protein-fat-salts composition which is substantially free of fermentable sugars and in which the protein and salts are capable of forming a stable matrix for the fat. Milk protein is treated with a protease to hydro- lyze the protein and to develop cheese flavor components and precursors therefor. The hydrolyzed milk protein is mixed with the protein fat-salts composition and the prod- uct is made into curd which is cured in an unusually short period of time to provide cheese or cheese-like products. Butter fat may also be treated with a lipase to hydro- lyze the butter fat and to develop cheese flavor components and precursors therefor. The hydrolyzed butter fat is also mixed with the protein-fat-salts composition prior to making curd.
