Improved Method for Determining Food Protein Degree of Hydrolysis

, 2001
When producing hydrolyzed proteins, it is important to determine the degree of hydrolysis (DH). The trinitro-benzene-sulfonic acid (TNBS) method is well established with regard to enzymatic hydrolysis. However, this method is laborious, cannot be used to

CORN GLUTEN HYDROLYSIS BY ALCALASE: KINETICS OF HYDROLYSIS

Chemical Engineering Communications, 2010
In the present study, the reaction kinetics of corn gluten hydrolysis by Alcalase, a bacterial protease produced by Bacillus licheniformis, was investigated. The reactions were carried out for 10 min in 0.1 L of aqueous solutions containing 10, 20, 30, 40, and 50 g protein L−1 corn gluten at various temperature and pH values. The amount of enzyme added

Hydrolysis of esters by staphylococci

International Journal of Food Microbiology, 1997
The objective of this work was to characterize the hydrolysis of esters by staphylococci in order to understand if they could contribute to the release of free fatty acids in sausage. Cell-free extracts and extracellular concentrates of staphylococci were examined for esterase activities against p-nitrophenyl esters and for lipolytic activities against

Hydrogen generation via hydrolysis of magnesium with seawater using Mo, MoO2, MoO3 and MoS2 as catalysts

, 2017
Hydrogen generation is one of the enabling technologies for realization of hydrogen economy. In this study, we developed a high-performance hydrogen generation system using the transition metal Mo and its compounds (MoS2, MoO2, and MoO3) for catalyzing ...

Effect of sulfate groups from sulfuric acid hydrolysis on the thermal degradation behavior of bacterial cellulose.

Biomacromolecules, 2004
When used as fillers in polymer composites, the thermostability of cellulose crystals is important. Sulfate groups, introduced during hydrolysis with sulfuric acid, are suspected to diminish the thermostability.
