用发酵法提取马铃薯渣果胶的工艺研究

Research on Technique of Extracting Potato Slag Pectin with Fermentation

马铃薯渣是马铃薯淀粉加工而产生的副产物,主要组成成分包括脂肪、矿物质、游离氨基酸、纤维素、半纤维素、蛋白质、淀粉及果胶。通过介绍马铃薯渣的主要成分及性质,并以马铃薯渣为原料,以经诱变的酵母为出发菌种,采用响应面分析法分析发酵法提取马铃薯渣果胶的工艺过程,并研究了其对果胶提取率的影响,进而证实了发酵法提取马铃薯渣果胶工艺的有效性。

Potato slag is a by-product of potato starch processing with the main components of fat, minerals, free amino acid, cellulose, hemicellulose and protein, starch and pectin. This paper, through the introduction of the main ingredients and properties of potato residue, taking the potato residue as raw material, making the mutation yeast as starting yeast strains, analyze the process of extracting pectin potato slag pectin through fermentation by using the method of response surface analysis, studies its influence on pectin extraction yield, and confirms the validity of the process of extracting potato slag pectin through fermentation.
