In this work, amphiphilic surfactant was obtained using dehydroabietic acid from pine rosin and then preadsorbed with acid-pretreated bamboo residues (AP-BR) to block the residual lignin adsorption si...
The effect of incubation temperature (28.18-61.82°C), incubation time (97.5-652.5 min) and pectinase concentration (0.64-7.36 mg/25 g bael pulp) on juice yield, viscosity and clarity of juice were stu...
采用酶法制备蛋清肽,色谱纯化ACE抑制活性组分并鉴定其一级结构。通过考察底物质量分数、加酶量、酶解温度和pH值对水解度的影响,结合多元线性回归设计和二次回归正交组合设计建立蛋清ACE抑制肽酶解工艺模型,并经液相色谱串联质谱鉴定其一级结构。结果表明:最佳酶解工艺为底物质量分数8%、pH值10.73、加酶量12.14%及酶解温度56.80℃,酶解物纯化后半抑制质量浓度为0.18mg/mL。液相色谱串...
Oat is an important cereal for human consumption and has relatively higher protein content compared to other cereals. Numerous studies have shown that oat polyphenols had antioxidant properties but n...
Myofibrillar protein was extracted from grass carp, a freshwater fish, and hydrolysed using five commercial proteases (papain, pancreatin 6.0, bromelain, Neutrase 1.5MG, and Alcalase 2.4 L). The antio...
研究了松针总黄酮(PNF)的抗氧化性能和酶法修饰提高PNF抗氧化性能的条件。结果发现,PNF的体外抗氧化性能很强,DPPH自由基清除效果与抗坏血酸相似,羟基自由基、超氧阴离子清除率分别约为抗坏血酸清除率的4倍、2倍,Fe3+还原能力的EC50约为抗坏血酸EC50的1/2.8。用β-葡萄糖苷酶对PNF进行酶解修饰,其最优工艺参数为:酶解温度40℃,酶添加量1/1000,底物质量浓度0.6g/L,酶解...
The enzymatic hydrolysis of soybean protein isolate (SPI) was investigated using commercially available Bacillus sp. proteases for reduction of soybean allergenicity. An alkaline protease, Proleather ...
Soybean protein isolate was hydrolyzed using two proteases (Protease M and Orientase 90N), and the inhibitory activity of angiotensin I-converting enzyme (ACE) and bitterness of the hydrolysates were ...
Sesame Protein Hydrolysate (SPH) was prepared from defatted sesame (Sesamum indicum L.) flour (DSF) after screening with different proteases. The proteases under different conditions showed varied eff...
The conditions of enzymatic hydrolysis of thioglucosides, which are the precursors of the pungent components in Armoracia rusticana grown in China, were studied. The effects of incubation time, temper...
In recent years, there has been a tremendous growth in the use of enzymes in wet-processing of textiles. Of the many enzymes suitable for textile applications, cellulase is one of the most important. ...
