An electrophoretic method is described for determining the molecular weight distribution of hyaluronan (HA). The method involves separation of HA by electrophoresis on a 0.5% agarose gel, followed by detection of HA using the cationic dye Stains-All (3,3'-dimethyl-9-methyl-4,5,4'5'-dibenzothiacarbocyanine). The recommended sample load is 7 micrograms. Calibration of the method with HA standards of known molecular weight has established a linear relationship between electrophoretic mobility and t
Although enzymatic hydrolysates of soy protein isolate (SPI) have physiological functionality, partially hydrolyzed SPI exhibits bitter taste depending on proteases and degree of hydrolysis (DH). To determine proteolysis conditions for SPI, it is important to evaluate bitterness during enzymatic hydrolysis. Taste dilution analysis (TDA) has been developed for the screening technique of taste-active compounds in foods. The objectives of the present study were to evaluate bitterness of enzyme-hydr
ABSTRACT Soy protein hydrolysates (SPH) were obtained by Alcalase hydrolysis of soy protein. Antioxidant activity of SPH was measured with a lipid peroxidation inhibitory activity and lipid oxidation was evaluated by measuring the thiobarbituric acid (TBA) and peroxide value. The potent antioxidant peptide was purified using ultrafiltration and consecutive chromatographic methods including FPLC and reverse-phase high-performance liquid chromatography. The antioxidant activity having a specific a
