人参蛋白真空冷冻干燥技术工艺研究
Freeze-drying Processing Technology of Ginseng Protein
摘要
Abstract
Objective To study the protectant and the curve of freeze-drying and establish the best technology of freeze-drying for ginseng protein.Method Based on the shape,color and dispersion as indexes,we investigated the effect of different types and concentrations of freeze protectant on ginseng protein samples to confirm the best protective agent.Moreover,we used electric resistance method to detect melting point and optimized the program of drying analysis to establish the freeze-drying curve of ginseng protein on the basis of T-SOD enzyme activity.Results The results showed that 5% of mannitol as freeze-dried protective agent kept ginseng protein freeze-dried samples in good appearance,shape and dispersion.The general melting point of ginseng protein was-4 ℃.The freeze-drying curve began to lyophilize at-40 ℃ for 2 h and keep-10 ℃ within 6 h,then heat up to-4 ℃ for 10 h,again after heating up to 5 ℃ within 1 h,15 ℃ within 1 h for 2 h.Conclusion The best freeze-drying process of ginseng protein is determined through optimizing the protectant and the curve of freeze-drying,which could provide good experimental technology for its industrialized production.关键词
