A process for preparing a milk protein hydrolysate comprising hydrolysing a milk-based proteinaceous material with a microbial alkaline serine protease in combination with bromelain, a protease from Aspergillus and a protease from Bacillus.

A fluid gel may be produced by stirring a solution containing a protein and transglutaminase and the like.

A casein hydrolysate formed by controlled hydrolysis of a casein substrate by an aspergillus-derived (fugal) proteolytic preparation is described. The controlled hydrolysis employs a FlavorPro-Whey formulation and a degree of hydrolysis (% DH) of from 5% DH to 15% DH. The Hydrolysate has at least a 98% reduction in antigenicity compared to intact sodium caseinate and a mean bitterness score of less than 30%. The invention also provides a low molecular weight fraction of casein hydrolysate of the invention which is substantially free of peptides having a molecular weight greater than 5 kDa.

A composition including protein hydrolysates derived from milk is obtained by the treatment of enzymes derived from microorganisms. A trypsin-like enzyme and a chymotrypsin-like enzyme are used. The composition is in particular intended for inducing tolerance in infants with the effect of modulating the potential occurrence of allergies later in life. The composition can also be used in sick adult patients. Preferably the composition is an infant formula, infant follow-up formula, growing-up milk or baby food or an enteral complete nutritional composition.

The present invention aims to provide a method for producing a protein-containing liquid food in which an unpleasant texture is improved, and the like. A method for producing a modified protein-containing liquid food, including treating a food ingredient containing a protein with phospholipase D. An enzyme preparation for modifying a protein-containing liquid food, which preparation contains phospholipase D. A method for modifying a protein-containing liquid food, including treating a food ingredient containing a protein with phospholipase D.

The present invention relates to a method of preparing a casein hydrolysate by hydrolysis of casein with endogenous plasmin, and the casein hydrolysate obtainable by the method. In particular, the present invention relates to a method of preparing a casein hydrolysate without adding any exogenous enzymes such that an organic casein hydrolysate is obtained.
