冷破碎苹果皮渣中多糖提取工艺优化及除杂方法研究
Study on optimization of extraction process and deprotein, depigment of polysaccharides from apple cold-break peel pomace
摘要
Abstract
Quadratic orthogonal rotation combination design was used to study the effects of some main technological conditions,including extraction temperature,extraction time and ratio of solvent to solid,extraction number on extraction yield of apple polysaccharides from apple cold-break peel pomace.Effects of apple cold-break peel pomace extraction rate of polysaccharides order of the three factors was extraction temperature, extraction time,liquid ratio.The optimized regression equation was Y =7.5966 +0.5336X1 +0.4946X2 + 0.2298X3 + 0.3611X12 +0.1914X22.The maximum extraction yield of 11.28% was achieved by the optimal extraction for 5.7h at 95.2℃ with a ratio of solid to solvent 1:93.The results showed that the percentage of removed protein for the HCl method was 80.2% ,and the percentage of decomposed polysaccharide was 9.7%.The dialysis was an optimal method for removing pigments,the light transmittance of the solution was 65.9% and increased by 23.5% ,and the rate of decomposed polysaccharide was 31.7%.关键词
