Study on stability of wheat germ oil and lipase activity
The purpose of the present study was follow the influence of periodical storage (at room temperature, 25-30°C), on the stability of oil including primary and secondary oxidation, total oxidation as well as conjugation. Color intensity at 430 nm of the oil samples was also evaluated to show changes of color during periodical storage. It was generally found peroxide value, panisidine, total oxida...
متن کاملInactivation of Lipase and Lipoxygenase of Wheat Germ with Temperature-Controlled Short Wave Infrared Radiation and Its Effect on Storage Stability and Quality of Wheat Germ Oil
Wheat germ (WG) is quite susceptible to deterioration due to the presence of lipase (LA) and lipoxygenase (LOX). Therefore it is indispensable to adopt a stabilization step to decrease the activity of LA and LOX while retaining a maximum level of nutrients. But over-drying can make foodstuffs more susceptible to autoxidation. So a stabilization protocol for inactivating LA and LOX of WG with a ...
متن کاملThe Effect of Humidity and Compactional Pressure on the Wheat Germ Lipase Activity
The use of proteins and peptides as human therapeutics has been increased in recent years. Lipase is a relatively homogeneous proteinaceous enzyme indicated in maldigestion. The purpose of the present study was to evaluate the effect of humidity along with compactional pressure on the enzymatic activity of wheat germ lipase. Samples of lipase powder were kept at different relative humidity (RH)...

متن کاملStorage Stability of Wheat Germ Oil Encapsulated within Nanostructured Lipid Carriers
The present study aimed to evaluate the effect of surfactant composition on the physical properties of nanostructured lipid carriers (NLCs) containing wheat germ oil (WGO) and to investigate the influence of both surfactant composition and pH on the oxidative stability of WGO encapsulated within the NLCs. The results showed that the smallest particle size (52.7 nm) was related to the NLC with t...
