采用十二烷基硫酸钠-聚丙烯酰胺凝胶电泳(SDS-PAGE)和免疫印迹(Western blot)方法,通过体外模拟消化实验分析水产品主要过敏原原肌球蛋白(Tropomyosin,TM)和小清蛋白(Parvalbumin,PV)的消化特性,主要研究酶/蛋白的比值、pH值对模拟胃液(SGF)消化过敏蛋白稳定性的影响。结果表明,提高胃蛋白酶的相对量使甲壳类水产品TM从消化稳定性转变成消化不稳定性,但是TM具有较强的消化稳定性,当酶/蛋白比值提高到10/1时,一些稳定的降解条带仍未被完全分解;当pH≥5时胃液消化会受到抑制,甲壳类水产品TM和鱼类PV均不会被消化分解。在优化条件(0.33U酶/μg蛋白,pH3.5)的SGF消化试验中,甲壳类水产品TM具有较高的...

Oil tree is an important economic plant,also an important source of edible oil in China.With oil tea variety optimized and standardization of planting,the mechanization of harvesting fruits of oil tea become a new area of forestry machinery,the materials collection device is an important part of oil tea fruits picking machine.A collection and conveying device driven by pneumatic vacuum pressure has been decided on the basis of analyzing and comparing the three kinds of materials collection devices such as conveying the material...
