国内外市场上全麦粉的品质分析研究

Study on Quality of Whole Wheat Flour from Domestic and Overseas Market

从国内外市场上收集了22个全麦粉产品，对其卫生指标和品质指标进行了分析研究。结果表明，所有全麦粉产品的卫生指标均达到了我国相关国家标准的要求；水分、降落数值、湿面筋含量、蛋白质、粗脂肪、脂肪酸值、烷基间苯二酚（ARs）、总膳食纤维和灰分9个品质指标测定结果显示：企业在制作全麦粉时，都偏向于选择高筋小麦。通过ARs、膳食纤维及灰分等指标数据与实验室研制的标准全麦粉对比，充分表明国内外全麦粉产品质量参差不齐，大部分产品仅添加了部分麸皮，不符合全谷物的定义。烷基间苯二酚、总膳食纤维和灰分值是评价全麦粉品质的3个重要指标。

The health and quality indexes of 22 whole wheat flour products from domestic and overseas market were analyzed.
