RELATIONSHIP BETWEEN WHEAT MILLING STREAM QUALITY AND SEPARATION EFFECT OF WHEAT STARCH AND GLUTEN BY CENTRIFUGAL PROCESS

Selecting 21 flour samples from different milling systems,we studied the relationship between the wheat milling stream quality and the separation effect of wheat starch and gluten by centrifugal process.The results showed that the quality properties of the flour samples from different systems and its influences on the separation effect were different from each other.The correlation analysis of the separation effect showed that the bran speck content and the ash content were in highly significant negative correlation with the A starch yield,and in highly significant positive correlation with the dry gluten yield;the water absorption rate was in significant positive correlation with the A starch yield,but in highly significant negative correlation with the dry gluten yield;and the gluten index had no obvious correlation with the A starch yield and the dry gluten yield.The results showed that the bran speck content and the ash content had high effects on the starch separation effect;and the higher the bran speck content and the ash content were,the lower the starch yield was,and the higher the dry gluten yield was.
