活性炭与大孔树脂对美洲大蠊脱脂膏的脱色效果比较(英文)

目的]探讨活性炭及大孔树脂两种脱色工艺对美洲大蠊脱脂膏的脱色效果,对比两种脱色工艺的优缺点。方法]美洲大蠊脱脂膏用活性炭和大孔树脂脱色后,进行冷冻干燥得到固体脱色物,然后通过考察收得率、脱色率、蛋白保留率及脱色的操作过程,比较两种脱色工艺的有缺点。结果]两种方法均能用于脱色。从收得率及蛋白保留率看,大孔树脂优于活性炭;从脱色率及操作过程看,活性炭脱色优于大孔树脂。结论]该研究结果表明,若试验所需成分以蛋白为主,可采用大孔树脂脱色;若所需成分不是以蛋白为主,则可采用活性炭脱色。

Comparison between Decolorization Effects of Activated Carbon and Macroporous Resin on Periplaneta americana L. Skimmed Cream

Objective] The aim of this study was to investigate the decolorization effects of activated carbon and macroporous resin on Periplaneta americana L. skimmed cream and compare the advantages and disadvantages of the two decolorization technologies. Method] Periplaneta americana L. skimmed cream was decolored with activated carbon and macroporous resin, and freeze-dried to collect solid decolorization products. By investigating the yield, decolorization rate, protein retention rate and decolorization operation process, the advantages and disadvantages of the two decolorization technologies were compared. Result] Both activated carbon and macroporous resin can be used for decolorization. To be specific, macroporous resin-decolorization is superior in the yield and protein retention rate, while activated carbon-decolorization is superior in decolorization rate and decolorization operation process. Conclusion] Macroporous resin-decolorization can be used if protein is the main ingredient required in the experiment, while activated carbon-decolorization can be used if protein is not the main ingredient required.
