Pumpkin protein meal was hydrolysed by alcalase, flavourzyme, protamex and neutrase. Physicochemical characteristics were evaluated by previously published methods using pumpkin protein hydrolysates (PPHs) and pumpkin protein meal (PPM) as a control. Hydrolysis had significantly changed the physicochemical characteristics of protein meal and its functionality as well. Different enzymes had diff...

Background: Culture media enrichment through the addition of protein hydrolysates is beneficial for achieving higher protein expression. Methods: In this study, designing the optimum mixture of four soy and casein-derived hydrolysates was successfully performed by design of experiment and specific productivity increased in all predicted combinations. Protein profile of recombinant CHO (rCHO) ce...

mehg and total mercury concentrations were determined in the muscle tissues of four fish species (cyprinus carpio, rutilus frisii, carassius auratus and esox lucius) from anzali wetland (guilan, iran). fish with the highest amount of mehg was selected to determine the thermodynamic parameters of mehg extraction. the extractions process was performed in the range of temperatures 331.15 to 367.15...

Objective: The present study was designed to determine in rats fed high cholesterol diet whether serum cholesterol concentration and its distribution in lipoprotein fractions could be improved by sardine (Sardina pilchardus) and sardinelle (Sardinella aurita) protein hydrolysates. In addition, lipid peroxidation in different lipoprotein fractions and in two target tissues of atherosclosis and t...

The effects of pelleted diets with different protein composition (fish, squid or soybean meals as main protein sources) on trypsin secretion and expression were studied in the lobster Panulirus argus. Trypsin secretion was shown to be maximal 4 h after ingestion. At this time, fish- and squid-based diets induced trypsin secretion, as well as up-regulation of the major trypsin isoform at the tra...

The canning industry plays a crucial role in the sector of marine foods, but produces several organic wastes and effluents with reduced economic value that must be upgraded to comply circular bioeconomy principles. Initially, we have searched best experimental conditions for hydrolysis upper lower halves from yellowfin tuna ( Thunnus albacares ) heads by four commercial proteases (alcalase, pap...

This study investigated the effects of bovine plasma protein (PP) hydrolysates on the antioxidant and quality properties of pork patties during storage. Pork patties were divided into 4 groups: without butylated hydroxytoluene (BHT) and PP hydrolysates (control), 0.02% BHT (T1), 1% PP hydrolysates (T2), and 2% PP hydrolysates (T3). Pork patty supplemented with PP hydrolysates had higher pH valu...

Enzymatic hydrolysates were prepared from bee bread using three proteases. The antioxidant properties of these hydrolysates were measured using four different methods. These had remarkable antioxidant activity similar or superior to that of 1 mM alpha-tocopherol. They also had high scavenging activities against active oxygen species as the superoxide anion radical and hydroxyl radicals. Moreove...
