小麦粉中阿拉伯木聚糖含量与小麦籽粒之间的关系

本文研究了面粉中阿拉伯木聚糖（简写AX）含量与小麦籽粒特性之间的关系,研究结果表明：AX含量与硬度（r=0.049）、水分（r=0.048）呈微弱正相关;与容重呈显著负相关（r=-0.215）,因为AX主要存在于小麦籽粒面筋蛋白和淀粉之间,当它们之间的AX多时,面筋蛋白和淀粉的量就会减少,容重就会减少;面粉中的AX与不完善粒（r=0.146）、出粉率（r=0.155）呈正相关,因为在小麦籽粒中,麸皮中AX含量占小麦籽粒的30%左右,当出粉率增加,会使一小部分的麸星进入面粉,从而使面粉中的AX增加。

The Relationship Between The Content Of Arabinoxylan In Wheat Flour And Whweat

The relationship between the the content of arabinoxylan and the characteristics of wheats grain was studied in this article,the results showed that there was a weak positive correlation between AX content and hardness(r=0.049),moisture(r=0.048);and there was respectively the negative relation between AX content and bulk density(r=0.215),because AX mainly existed between the gluten and starch,when the AX content between them increased,the amount of gluten and starch would reduce,so the bulk density would reduce;the AX in the flour with imperfect grain(r=0.146)and flour extraction(r=0.155)were positively correlated,because when the imperfect grain increased,the content of stars in the bran of the flour would be relatively increased,the content of AX in the bran accounted for about 30% of the wheat grain,when the imperfect grain increased,the AX in the bran would come into the flour,which made the amount of AX in the flour increased.
