Bovine and camel chymosin are aspartic peptidases that are used industrially in cheese production. They cleave the Phe105-Met106 bond of the milk protein κ-casein, releasing its predominantly negatively charged C-terminus, which leads to the separation of the milk into curds and whey. Despite having 85% sequence identity, camel chymosin shows a 70% higher milk-clotting activity than bovine chym...

this study prepared new edible composite film by blending kefiran with whey protein. the film-forming solutions used different ratios of kefiran to whey protein (70/30, 50/50, 30/70, 10/90) and were cast at room temperature. the effects of the addition of whey protein on the physical, mechanical and water-vapor permeability (wvp) properties of the film were investigated. it was found that an in...

The balance between free radicals and antioxidants is an important factor for maintaining health and slowing disease progression. The use of antioxidants, particularly natural antioxidants, has become an important strategy for dealing with this cause of widespread diseases. Natural antioxidants have been used as therapeutic tools against many diseases because they are safe, effective, and inexp...

Novel antihypercholesterolemic bioactive peptides (BAP) from peptic camel whey protein hydrolysates (CWPH) were generated at different time, temperature, and enzyme concentration (%). Hydrolysates showed higher pancreatic lipase- (PL; except 3 CWPH) cholesterol esterase (CE)-inhibiting potential, as depicted by lower half-maximal inhibitory values (IC50 values) compared with nonhydrolyzed prote...

today, by increase in production capacity of dairy manufactures, high amounts of whey is produced as a by product of cheese production. in recent decays, high amount of whey production sometimes up to 8 times more than produced cheese-, its high bod and its environmental problems caused in particular attention to whey processing and its usage in food products. according to promotions occurred i...

       Food packaging extensively uses plastic films and containers of petroleum-based polymers for their excellent functional properties and competitive price. Plastic packaging has become a central focus of waste reduction efforts, particularly in aesthetic terms of damage to flora and fauna. Presently, consumers require greater quality and longer shelf lives for their foodstuffs, while they ...

A 17.5 kDa protein was isolated from porcine whey by reverse phase HPLC and identified as a putative whey acidic protein (WAP) homologue by sequencing 35 and 40 amino acid residues of the amino- and carboxy-terminus respectively. Degenerate oligonucleotides to both of these amino acid sequences were designed and used in reverse transcriptase PCR with RNA from lactating porcine mammary gland as ...
