摘要
研究了喷雾干燥的工艺参数喷液流量、介质温度对亚麻胶含水率、粘度和乳化性的影响。试验表明,上述工艺参数不影响亚麻胶的乳化性,但对含水率和粘度影响显著。建立了含水率及粘度与喷液流量、介质温度和介质流量之间的数学模型,并在保证亚麻胶质量的条件下得出了优化工艺条件:喷液流量690mL/min,介质温度186.5℃,介质流量95.5m3/h,此时成品亚麻胶含水率为10.89%,粘度为74mPa·s。
The effects of spray drying parameters on moisture content, viscosity, and emulsifying property of flaxseed gum were studied. The spraying rate, air temperature and air flow rate were selected as the experimental factors. The results reveal that all of the above factors do not affect the emulsifying property but affect the moisture content and viscosity significantly. Mathematical models established by orthogonal regression experiment were used to optimize the spray drying process. The optimized process conditions of spraying rate, air temperature and air flow rate are as follows: spraying rate is 690 mL/h, air temperature is 186.5℃ and air flow rate is 95.5 m^3/h. Under the optimized conditions, the moisture content of dried gum is 10.89% and the viscosity of dried gum is 74 mPa·s.
