摘要:
The invention relates to the production of bioactive products that are derived from milk proteins for the production of bioactive milk products derived from milk proteins, particularly caseins. The 16 inventive peptides can be obtained chemically, biotechnologically or by means of enzymatic treatment from proteins containing same and give rise to peptides with an antimicrobial activity, an in vitro angiotensin converter inhibitor activity and/or antihypertensive activity and/or antioxidant activity. Said nutraceutical products are suitable for use in the food and pharmaceutical industries, both in the form of a hydrolyzate or bioactive peptides.
摘要:
The invention provides a method for the prevention or treatment of virus infections comprising administering, to a human or animal individual susceptible to or suffering from a virus infection, an effective amount of one or more casein phosphopeptides (CPP). Also provided is a composition containing such casein peptides and further agents such as vitamin C and/or nutritional components for use in treating or preventing virus infections.
摘要:
The present invention relates to an active agent, in particular a metalloproteinase inhibitory agent of casein-derived peptides obtained by hydrolysis of casein by a food grade bacteria. The invention also relates to the manufacture of an active agent, in which a food grade bacteria of the genus Lactobacillus helveticus is contacted with casein in order to perform a hydrolysis and obtain casein-derived peptides exhibiting metalloproteinases inhibitory property. The present invention also includes isolated and purified inhibitory peptides obtained by hydrolysis of casein by the bacteria.
摘要:
a peptide product is made by enzymatically hydrolyzing a protein, such as whey protein concentrate, in two stages. A fungal protease is used to hydrolyze the protein in each stage. The hydrolyzed protein is dried to form a peptide product. The peptide product is non-allergenic and lacks the bitter taste that some other peptide products have. If can be used to make milk replacement products and various other food products.
摘要:
A nutritional enteral composition intended for favoring the growth and maturation of non-mature gastro-intestinal tracts of young mammals, which contains as a protein source a mixture of dietary protein hydrolysates and intact proteins being partly in the form of bioactive peptides.
摘要:
The present invention describes protein hydrolysates: obtainable by the hydrolysis of a protein containing substrate; comprising free amino acids and peptides; and wherein the molar fraction of at least one free amino acid, present in the protein hydrolysate is at least a factor 2.5, preferably at least a factor 3, more preferably at least a factor 3.5 times higher than in a hydrolysate of the same protein containing substrate which has been completely hydrolysed to free amino acids, wherein the molar fraction of the at least one free amino acid in the protein hydrolysate is at least 25%; and wherein the Amino Acid Quotient (AAQ) in the protein hydrolysate is at least 10%. These protein hydrolysates can be used in the preparation of food compositions, wherein these protein hydrolysates provide for novel and unexpected flavours. Moreover these protein hydrolysates are applicable in personal care applications.
摘要:
Methods and compositions for promoting tolerogenic immune responses or treating immune responses to food antigens comprise Lactobacillus GG. Oral administration of Lactobacillus GG to patients such as human infants may promote a tolerogenic immune response to antigens in cow's milk.
摘要:
A method for producing a protein hydrolysate with low bitterness by contacting a protein with a protease having a low specificity to cleave a site of a hydrophobic amino acid residue in the protein.
摘要:
A method for the selective hydrolysis of casein/caseinate in the presence of at least one further protein constituent other than casein/caseinate, the casein/caseinate and the at least one further protein constituent being brought into contact with a proteolytic enzyme under conditions for the hydrolysis of the casein/caseinate, characterized in that the casein/caseinate and preferably also the at least one further protein constituent are in an essentially dissolved state, and in that a proteolytic enzyme is a proteinase specific for casein/caseinate, such that the casein/caseinate is hydrolysed while the further protein constituent remains essentially intact. This method can be used, in particular, for the preparation of a hydrolysed casein preparation or alternatively for the preparation of a milk protein preparation, in particular, a whey protein preparation which has been stripped of casein/caseinate. The invention further relates to the preparations thus obtained, which have beneficial properties with respect to allergic reactions to milk proteins, and diabetes.
摘要:
The invention relates to the use of a protein component based on conventional proteins used for the production of foods, at least 20 wt-% thereof having a phosphate residue, which is covalently bound to the protein, whereby 50 to 100 wt-% of the proteins including at least one covalently bound phosphate residue, are subjected to a dephosphorylation reaction wherein 20 to 100% of the covalently bound phosphate residues were removed, for a treatment of adult and adolescent patients, as well as of babies and small children suffering from a disturbed gastrointestinal motility and of reflux-predisposed patients. The use of said protein component not only allows for a sufficient protein supply but it also passes rapidly through the stomach and prevents the stomach contents from flowing back into the oesophagus.
