| 中文摘要: |
| 通过单因素实验研究中和工序蛋白溶液质量分数、中和pH、消泡剂添加量、干燥喷嘴孔径和添加抗结剂对大豆分离蛋白流动性和扬尘性的影响。结果表明：高蛋白溶液质量分数、低中和pH、大喷嘴孔径均利于提高大豆分离蛋白粉的流动性，降低其扬尘性；其中高流动性、低扬尘度大豆分离蛋白粉加工的最佳工艺参数为蛋白溶液质量分数14%、中和pH 6.5、干燥喷嘴孔径1.6 mm、消泡剂添加量0.05%，另可根据需要添加适当二氧化硅类的抗结剂。 |
| 英文摘要: |
| The effects of the mass fraction of protein solution, neutralization pH, dosage of defoaming agent, pore size of the dry nozzle and addition of anticaking agent on the flowability and fugitive dust of soybean protein isolate were studied by single factor experiment. The results showed that high mass fraction of protein solution, low neutralization pH and large nozzle pore size were favorable for enhancing the flowability and reducing the fugitive dust of soybean protein isolate powder. The optimal processing parameters for the processing of high flowability and low fugitive dust soybean protein isolate powder were obtained as follows: mass fraction of protein solution 14%, neutralization pH 6.5, nozzle pore size 16 mm, and dosage of defoaming agent 0.05%. In addition, a certain anticaking agent could be added according to the need. |
