【摘要】 利用微生物中性蛋白酶、微生物谷氨酰转氨酶(MTG)二者复合改性大豆分离蛋白(SPI),结果发现,双酶复合改性SPI的溶解性、吸水性、保水性和吸油性相关功能性显著增加,分别比对照提高了26.5%、48%、173%、35%,并经电镜观察改性SPI微观结构,探讨了SPI改性机理。更多还原

【Abstract】 When SPI is modified by neutral proteinase and microtransgluminase(MTG),the functional properties of comprehensive modified SPI are improved,the Solubility,the water absorption,the water holding capacity,the oil absorption property of modified-SPI is higher than original SPI by 26.5 %,48 %,173 %,35 %.Then the modification mechanism is discussed after modified-SPI are inspected by the electron microscope.更多还原
