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)

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

[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。

[Objective] The aim of this study was to investigate the decolorization ef- fects 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.
