Preparation, deproteinization, characterization, and antioxidant activity of polysaccharide from Medemia argun fruit.

In this study, the crude polysaccharide from argun palm (Medemia argun) fruit was extracted with hot water and deproteinized by four different methods. Its structure characterization, thermal property and antioxidant activity were investigated by FT-IR spectroscopy, Scanning electron microscope, Congo-red, I-KI, DPPH assay, ABTS assay, TGA and DSC analysis. It indicated that the NaCl method was the best method in deproteinization.

Review of Advances in Bioactive Low-Molecular-Weight Compounds, Extracts, and Biology of Phellinus sensu lato Mushrooms (Agaricomycetes) from 2011 to 2017.

Various diseases such as cancer, hyperglycemia, and obesity negatively influence people's health and daily life. Mushroom species are miniature pharmaceutical factories producing hundreds of novel constituents with a long history of use in Oriental medicine. As a new therapy, they have attracted much attention owing to their potent therapeutic activity.

Thermal and single frequency counter-current ultrasound pretreatments of sodium caseinate: enzymolysis kinetics and thermodynamics, amino acids composition, molecular weight distribution and antioxidant peptides.

Background: Due to the disadvantages of traditional enzymolysis, pretreatments are crucial to enhance protein enzymolysis. Enzymolysis kinetics and thermodynamics, amino acids composition, molecular weight distribution, fluorescence spectroscopy and antioxidant activity of thermal (HT) and single frequency counter-current ultrasound (SCFU) pretreated sodium caseinate (NaCas) were studied.

Results: Enzymolysis of untreated NaCas (control) improved significantly (P < 0.
