复配型改良剂对青麦仁面条品质影响的研究

    STUDY ON THE EFFECT OF COMPOUND MODIFIER ON QUALITY OF GREEN WHEAT KERNEL NOODLE

    • 摘要: 青麦仁中含有多种营养物质,添加到面条中不仅能丰富面条的花色品种,而且使面条具有更高的营养价值,但是青麦仁的添加降低了面条的蒸煮品质及口感,因此选取羧甲基纤维素钠(CMC)、黄原胶、磷脂作为青麦仁面条的品质改良剂,研究了不同添加剂、不同添加量对青麦仁面条干物质吸水率、蒸煮损失率及感官评分的影响。单因素试验结果表明,3种改良剂都对青麦仁面条的品质有一定的改良效果,CMC添加量为0.8%~1.6%,黄原胶添加量为0.4%~1.2%,磷脂添加量为0.8%~1.6%时干物质吸水率、蒸煮损失率、感官评分较好。通过响应面试验得出3种添加剂的影响依次为CMC>黄原胶>磷脂;黄原胶与磷脂交互作用> CMC与磷脂交互作用> CMC与黄原胶交互作用;复合改良剂配方为CMC添加量1.2%,黄原胶添加量0.8%,磷脂添加量1.2%。

       

      Abstract: The green wheat kernel contains a variety of nutrients including carbohydrates,protein,unsaturated fatty acids,potassium,calcium,magnesium,and vitamins.Making bread and biscuit of green wheat kernel provides the feasibility for making of the green wheat noodle.Adding green wheat kernel increased the nutritional value of noodles but reduced the cooking quality and taste of noodle.Therefore,three additives including sodium carboxymethyl cellulose (CMC),xanthan gum and phospholipid were selected to improve noodle quality in this study.The effects of different proportion and amount of these additives on green wheat kernel noodle quality were investigated.The indicators including dry matter water absorption rate,cooking loss rate and sensory score were evaluated.The single factor experiments indicated that three amendments could improve green wheat kernel noodle quality,and the optimal adding amount of CMC was 0.8%-1.6%,xanthan gum was 0.4%-1.2%,and phospholipid amount was 0.8%-1.6%.T response surface methodology analysis demonstrated that the influence of the three additives was CMC>xanthan gum>phospholipid and xanthan gum phospholipid interaction>CMC phospholipid interaction>CMC xanthan gum interaction.The experimental verification of reliability optimization showed that the composite modifier formula was CMC1.2%,xanthan gum 0.8%,phospholipid 1.2%.
