Research on Influencing Factors of Drying Process for Brain-Boosting Rice Flour for Middle-Aged and Elderly
As a nutritional supplement for the middle-aged and elderly,the drying process of brain-boosting rice flour directly affects its taste and quality.In this paper,the drying process parameters of brain-boosting rice flour were optimized through response surface test.The results showed that the addition of waxy corn starch was the main influencing factor of water absorption index and sensory score in the drying process parameters of brain-boosting rice flour.The optimized drying process of brain-boosting rice flour after the response surface test is drum speed 3.0 r·min-1,steam pressure 0.5 MPa,and the amount of glutinous corn starch added 21%.Under these conditions,the average sensory score of the samples is(94.3±0.6)points,and the average water absorption index is 4.31.The confidence interval of the test value is 95%,and there is a good consistency between the actual value and the predicted value of the model,indicating high reliability of the model prediction.
