BACKGROUND Casein is the main proteinaceous component of milk and has made us interest due to its wide applications in the food, drug, and cosmetic industries as well as to its importance as an investigation material for elucidating essential questions regarding the protein chemistry. Enzymatic hydrolysis is an important method commonly used in the modification of protein structure in order to ...

Fermentation is an economical method for obtaining protein hydrolysates. The purpose of the scientific research was to perform a comprehensive analysis physicochemical, technological, and functional properties hydrolysates obtained by microbial fermentation. results showed that fermented with propionic acid bacteria bifidobacteria have better physicochemical technological indicators compared co...

In order to utilize silver carp (Hypophthalmichthys molitrix), which is abundant and very cheap fresh-water fish in China, defatted silver carp muscle was hydrolysed by compound protease to achieve angiotensin-converting enzyme (ACE) inhibitory peptides. The protein hydrolysates were fractionated into low and high molecular weight fractions using an ultrafiltration (UF) membrane system. The ACE...

The utilization of industrial sunflower meal to produce protein-rich products for the food industry is an alternative approach for better and more efficient use of this agricultural by-product. Sunflower meal proteins possess specific functional properties, which however need improvement to broaden their potential as supplements for delivering high--quality products for human nutrition. The aim...

Casein and whey protein were hydrolyzed using 11 different commercially available enzyme preparations. Emulsion-forming ability and emulsion stability of the digests were measured as well as biochemical properties with the objective to study the relations between hydrolysate characteristics and emulsion properties. All whey protein hydrolysates formed emulsions with bimodal droplet size distrib...

Background Hydrolysates are complex media supplements composed of many as well as different types of compounds. Within Frieslandcampina Domo’s Quality by Design project, detailed information of these compounds (annotation and quantification) has been generated. This was achieved for soy protein hydrolysates (Proyield Soy SE50MAF-UF) using metabolomics biochemical profiling. Biochemical profilin...

The stone fish is an under-utilized sea cucumber with many nutritional and ethno-medicinal values. This study aimed to establish the conditions for its optimum hydrolysis with bromelain to generate angiotensin I-converting enzyme (ACE)-inhibitory hydrolysates. Response surface methodology (RSM) based on a central composite design was used to model and optimize the degree of hydrolysis (DH) and ...

Enzymatic proteolysis is helpful to release bioactive peptides encrypted in food proteins. The antioxidant capability of soy protein isolate (SPI) hydrolyzed with a novel protease preparation from Chryseobacterium sp. kr6 was investigated. The antioxidant capacity of the hydrolysates was evaluated using radical-scavenging and metal-chelating assays. Maximum values for scavenging of 2,2’-azino-b...

BACKGROUND Walnut (Juglans regia L.), that belongs to the Juglandaceae family, is one of the nuts commonly found in Chinese diets. Researchers had obtained peptides from walnut protein hydrolysates, and these peptides exhibited the high antioxidant activities. The objective of this study was to develop a simple and convenient method for a facile and reproducible preparation of antioxidant pepti...
