Abstract
Abstract The complex enzymatic preparation is composed of the proteases of molds, of Penicillium candidum or Penicillium roqueforti, which do not form any bitter peptides, and of autolysates of lactic bacteria Streptococcus lactis or Lactobacillus casei. Adding this preparation to milk permits shortening by half the period of time required for ripening of cheeses. The product has a good taste and more plastic consistency.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
34 words
An enzymatic preparation for ripening of milk protein products, consisting essentially of a mixture of purified intracellular fungal protease from Penicillium candidum and of proteolytic enzymes obtained by autolysis of lactic acid bacteria cells.
Claim 2
Dependent Claim
34 words
An enzymatic preparation for ripening of milk protein products, consisting essentially of a mixture of purified intracellular fungal protease from Penicillium candidum and of proteolytic enzymes obtained by autolysis of lactic acid bacteria cells.
Claim 3
Dependent Claim
66 words
The enzymatic preparation as claimed in claim 1 consisting essentially of one part w/w of dry powdered fungal protease from Penicillium candidum with an activity of 5000 units per gram and three parts w/w of a dry proteolytic enzyme from lactic acid streptococci with a proteolytic activity of 70 units per gram or from lactic acid bacilli with a proteolytic activity of 140 units per gram.
