Many thiol-containing molecules show heavy metal complexation ability and are used as antidotes. In this study, the potential function associated with peptides (TCPs) from soy protein hydrolysates natural detoxicants for metals is reported. TCPs enriched by Thiopropyl-Sepharose 6B covalent chromatography had different molecular weight distributions well numbers of proton dissociable groups, depending on proteases degree hydrolysis. The major contribution sulfhydryl groups was confirmed...

In this study, we successfully prepared high internal phase emulsions (HIPEs) with 78%–90% oil based on pumpkin seed bodies (PSOBs) extracted by neutral extraction at 2800×g to 31000×g. There were no effects the protein compositions and contents of PSOBs different centrifugal forces. included oleosin (14.5 kDa) extrinsic proteins (22 kDa, 27 33 45 kDa). The HIPE-PSOB 78% had relatively spherical droplets, which was similar PSOB 72% 1000×g, while 83%–90% displayed polygonal droplets. All...

An experiment using 112 21-day-old male Arbor Acres broilers that were randomly allocated to 7 treatments with 8 replicates in a completely randomized design was conducted assess the effects of Ginkgo biloba leaves (Ginkgo biloba, GL) and extract (EGB) on utilization nutrients broiler chickens.

As an effective physical method for starch modification, ultrasonic treatment can significantly improve the chemical activity and quality of starch, but its mechanism needs to be further investigated. In this paper, ultrasonic-modified cassava octenyl succinic anhydride (OSA)-modified with low degree substitution were prepared under conditions. The effects ultrasound on structure properties native OSA-modified studied. results showed that crystallinity decreased from 30.7% 26.4%, reaction...

Abstract Background and objectives The chemical activity of starch granules is inert. purpose this study was to reveal the mechanism producing high‐quality modified by advanced equipment. Findings There were pores central cavities with loose structure in mung bean granules, so water could enter through under high hydrostatic pressure treatment. molecules be hydrated, even gelatinized. reaction efficiency (RE) cationic increased 32.20% other qualities (solubility, swelling degree,...

The purpose of this study is to reveal the mechanism preparing high quality modified starch by ultrasonic technology. In paper, and octenyl succinic anhydride with low degree substitution were prepared under conditions, using sweet potato as raw material. effects ultrasound on structure properties native studied see whether could produce mechanochemical effect starch. Then was effect. results showed that after treatment for 1 min, crystallinity decreased from 37.6 33.8% reaction efficiency...

At present, most studies have focused on the preparation of modified starches by dry grinding. As an excellent starch plasticizer, water might enhance action grinding structure granules, and improve gel properties starch. Therefore, this article explored influence mechanism corn based changes in its properties.The results showed that could make enter granules hydrate molecules, gelatinized after for 20 min. Thus, enhanced granules. Under plasticization grinding, mechanochemical effect...

Summary The purpose of this study was to expand the application range pea protein isolates by improving rheological properties their acid‐induced gels. A isolate ground for different durations, and changes in structure its gels were studied. Furthermore, influence mechanism grinding on gelation revealed. results showed that slightly changed secondary had a great impact tertiary structure. Compared with unground isolate, solubility increased from 45.89% 69.84%, water‐holding capacity 52.04%...

Peony seeds, an important oil resource, have been attracting much attention because of α-linolenic acid. Oil bodies (OBs), naturally pre-emulsified oils, great potential applications in the food industry.
