为更好地开发和利用马铃薯废渣,对马铃薯水溶性和水不溶性膳食纤维的提取分离工艺进行了研究。结果表明,α-淀粉酶酶解薯渣提取液中淀粉时水溶性膳食纤维提取液的最适pH值为6.5,酶液的使用量为每50mL提取液中添加20%的α-淀粉酶液1mL;活性炭脱色的最适条件为每50mL提取液中加入颗粒大小为60～80目的活性炭3.5g。对薯渣的护色处理有利于水不溶性膳食纤维的色泽改善及多酚物质的保存。

In order to develop and utility the potato residues,the extraction and separation process of water-soluble and water-insoluble dietary fiber were studied.The results showed that the optimum pH is 6.5,1 mL of 20% α-amylase solution was added into per 50 mL extracting solution.The optimum discolored conditions of active carbon was adding 3.5 g per 50 mL extracting solution with particle size for 60~80 mesh.Color protection of the potato residue was conductive to improve the colour and save polyphenols of insoluble dietary fiber.
