中文摘要 | 本研究利用Flavourzyme和Alcalae混合酵素對分離大豆蛋白進行水解,同時經由中空纖維超濾膜系統的篩分,以生產具有特殊機能性的產品。此產品的機能性包括:在pH2-範圍內,2.5%水解物濃度下的溶解度可達99%以上;在水活性Aw=0.6-0.9,22℃下的吸溼力為原大豆蛋白的1.8-3倍;在大豆油中2.5%的添加量大約和BHT 0.1%的抗氧化力相近。再者,大豆蛋白經水解後其抗原力價(log□)由7降到<1。本膜反應系統經長期運轉安定性的研究得知,此系統可連續生產含有上述機能特性的產品達16小時以上。 |
英文摘要 | Soy protein hydrolysate with specific functional properties was produced by hydrolysis of soy protein isolate with Alcalase and Flavourzyme in a continuous membrane system equipped with a hollow fiber ultrafiltration membrane. A concentration of 2.5% hydrolysate produced by this system was almost completely soluble over a pH range of 2~9. The moisture absorption capacity was 1.8~3 times that of intact soy protein isolate over a water activity range of 0.6~0.95. The antioxidant activity of the hydrolysate at a 2.5% addition level was close to that of BHT at a 0.1% addition level in soybean oil. As compared to intact soy protein isolate, the antigenicity (log2) of the hydrolysate decreased from 7 to <1. A long-term operation study elucidated that the membrane reactor system could maintain steady production for over 16 hr of soy protein hydrolysate with specific functional properties. |
