玉米糖原提取纯化的工艺研究及其保湿吸湿性能测定
Study on Extraction and Purification Process of Corn Glycogen and Determination of Its Moisture Retention and Hygroscopicity
摘要
Abstract
Fresh sweet corn was used as the raw material to prepare crude corn glycogen extract via the mechanical crushing-solvent precipitation method.Protein content was determined based on the Coomassie Brilliant Blue G-250 method,Then the deproteinization effects of pH adjust-ment,boiling,and the combined method of pH adjustment and boiling were compared.Finally the moisturizing and hygroscopic properties of the purified product were determined.The results showed that among the three deproteinization methods,the combined method(adjusting pH to 4.9 and boiling for 30 min)showed the best effect,reducing the protein content in corn glycogen to 6.44%,which was significantly lower than that of the pH adjustment method(minimum 8.02%)and the boiling method(minimum 9.50%).Under the conditions of 25℃and 41%relative humidity,the moisturizing performance of the purified corn glycogen was significantly superior to that of sodium alginate and glycerol,while its hygroscopic performance was obviously weaker than that of the two aforementioned substances.关键词
