Temperature, salt and water contents are key processing factors in dry-cured ham production. They affect how proteolysis, lipid oxidation, structure and texture evolve, and thus determine the sensory properties and final quality of dry-cured ham. The aim of this study was to quantify the interrelationships and the time course of (i) proteolysis, (ii) lipid oxidation, (iii) five textural paramet...

HLA-DR molecules are heterodimeric transmembrane glycoproteins that associate intracellularly with a polypeptide known as the invariant (I) chain. Shortly before expression of the HLA-DR αβ dimer on the cell surface, however the I chain is removed from the intracellular αβI complex by a mechanism thought to involve proteolysis . In this report, we show that treatment of purified αβI with the cy...

We examined the effects of orally administrated amino acids on myfibrillar proteolysis in food-deprived chicks. Plasma N(tau)-methylhistidine concentration, as an index of myofibrillar proteolysis, was decreased by the administration of Glu, Gly, Ala, Leu, Ile, Ser, Thr, Met, Trp, Asn, Gln, Pro, Lys and Arg but not by Asp, Val, Phe, Tyr or His to chicks. Orally administrated Cys was fatal to ch...

While the importance of modulatory proteolysis in research has steadily increased, knowledge on this process has remained largely disorganized, with the nature and role of entities composing modulatory proteolysis still uncertain. We built CaMPDB, a resource on modulatory proteolysis, with a focus on calpain, a well-studied intracellular protease which regulates substrate functions by proteolyt...

Abstract Green coffee processing has been hindered by low oil extraction yields from mechanical pressing and the need of using flammable hazardous solvents for defatting protein-rich cake before subsequent protein extraction. To replace use enable simultaneous lipids proteins green beans at reduced water usage, a multistage countercurrent process was scaled up 0.05 to 1.14 kg evaluated regardin...

The insulin-like growth factor-I and –II (IGF-I/ -II) are peptide hormones important for growth and metabolism. They stimulate cell proliferation and differentiation and inhibit apoptosis. In addition, they have insulin-like effects on glucose and amino acid metabolism. A large quantity of IGFs is synthesized in the liver and is subsequently transported to the circulation to act as endocrine fa...
