摘要
辛烯基琥珀酸淀粉酯是一种高效的食用变性淀粉胶,被广泛应用于乳化香精、软饮料、调味色拉油、酸乳和乳酪、糖果等食品中。本文采用红外光谱、紫外-可见光谱、电镜、HPLC等仪器,测定国内外不同来源的辛烯基琥珀酸淀粉酯的分子键类型、紫外吸收特征、糖组分、DE值、粘度、表面张力、乳化性参数等理化特性。结果表明,这些样品均具有较好的水溶性、表面活性、乳化性能和高浓低粘性,不同来源的样品组分不同,DE值差异较大,形成了DE小于5.0和DE大于20.0的两种不同类型的辛烯基琥珀酸淀粉酯产品。
Octenyl succinic anhydride starch hydrolysate （OSA-SH） was kind of efficient edible modified starch glue. It was widely used in emulsion flavor, soft drinks, salad oil, yogurt and cheese, sweets and so on. The structure and composition were investigated by means of Fourier transforms infrared （FT -IR） spectroscopy, UV - Visible spectroscopy, electron microscope, TGA , HPLC , etc. And its physico -chemical properties were determined by measuring type of molecular bond, characteristics of ultraviolet absorption, sugar composition, DE value,viscosity,surface tension,emulsifying properties and other indicators. Results showed that all the products had some good properties such as water solubility, high concentration and low stickiness, surface activity and emulsifying properties. Different sources of products had different component and different DE value. They form two different types of octenyl succinic anhydride starch hydrolysate products, one DE value was less than 5.0 and the other was more than 20.0.
