The transformation of shell eggs into safe liquid, frozen or spray-dried egg white with extended shelf life requires many technological operations that result in modifications to the egg white’s functional properties. During these processes, shear rates underwent by egg white may be responsible for part of the loss of its functional properties. The present study was aimed at measuring the effec...

------ARSTRACT-----Corn germ protein isolate (CGP[) was partially hydrolyzed with tryp~ sin and pepsin and succinylated at three levels. Various functional and electrophoretic properties of the native and modified protein were determined. Water absorption and foaming properties of COPT were improved by panial hydrolysis with trypsin: emulsifying capacity and nitrogen solubility were reduced~ oi...

Ren J., Song Ch.-L., Wang P., Li S., Kopparapu N.-K., Zheng X.-Q. (2015): Modification of structural and functional properties of sunflower 11S globulin hydrolysates. Czech J. Food Sci., 33: 474–478. The structural and functional properties such as solubility, emulsifying properties, foaming properties, oil binding capacity, and surface hydrophobicity of sunflower 11S globulin hydrolysates gene...

Proteins isolated from Mucuna pruriens bean were characterized and the foaming properties of both the flour and protein isolates determined. The pH-dependent protein solubility profile of the flour and isolates indicated that the isoelectric point ranged between 4.0 and 5.0. At all concentrations, the foaming capacity of both the flour and protein isolates increased with concentration increase;...

HRČKOVÁ M., RUSŇÁKOVÁ M., ZEMANOVIČ J. (2002): Enzymatic hydrolysis of defatted soy flour by three different proteases and their effect on the functional properties of resulting protein hydrolysates. Czech J. Food Sci., 20: 7–14. Commercial defatted soy flour (DSF) was dispersed in distilled water at pH 7 to prepare 5% aqueous dispersion. Soy protein hydrolysates (SPH) were obtained by enzymati...

Milk protein concentrate (MPC) is one of the major ingredients in foods due to its nutritional and functional properties including solubility, water binding, foaming, and emulsification. The foaming ability of milk proteins could potentially allow them to replace egg white protein; however, there is a lack of research on foaming properties of MPC. The goal of this study was to investigate the e...

Gelatines were extracted from mackerel and blue whiting bones after chemical or enzymatic pre-treatments and their functional properties (solubility, foaming and emulsifying properties) were analysed. The pre-treatment significantly (p<0.05) affected the composition and the functional properties of the extracted gelatines. The amino acid analyses showed that chemically pre-treated bone gelatine...

Broken rice is an underutilized by-product of milling. Proteins prepared from broken rice by treatments with alkaline protease and papain have been characterized with regard to nutritional and functional properties. The protein content and the protein recovery were 56.45 and 75.45 % for alkaline protease treatment, and 65.45 and 46.32 % for papain treatment, respectively. Protease treatment inc...

Poultry by-products and rainbow trout (Onchorhynchus mykiss) viscera are abundant and underutilized resources that can be used as a unique protein source to make protein hydrolysates. In this study protein hydrolysate were made from these two different sources with Alcalase 2.4L. The functional properties of Fish viscera protein hydrolysate (FPH) compared to poultry by-products protein hydrolys...
