基于合理氨基酸配比杂粮馒头工艺及评价研究

Study on the technology and evaluation of steamed bread based on reasonable amino acid ratio

目的探索合理氨基酸配比杂粮馒头的加工工艺与评价方法。方法以燕麦、荞麦、藜麦为原料研究符合人体需要的最佳氨基酸配比,磨粉后进行杂粮馒头制作工艺的研究,利用主成分分析对杂粮馒头的加工指标进行分析。结果燕麦、荞麦和藜麦的最佳配比为85:20:59(m:m:m),最接近人体最佳氨基酸模式;研究获得杂粮馒头的最佳配方为:燕麦含量44.8%、藜麦含量10.5%、荞麦含量31.2%、磨粉目数120目、酵母用量1.5%、谷朊粉用量12%(m:m)、加水量9:10(g:mL)。结论此配方制备的杂粮馒头质量最佳,为杂粮馒头的制作提供理论基础及建立评价方法,为杂粮开发加工提供数据参考。

Objective To explore the processing technology and evaluation method of reasonable ratio of amino acid to coarse grain steamed bread.Methods Using oats,buckwheat,and quinoa as raw materials,the best amino acid ratio that met the needs of the human body was studied,after grinding,the processing technology of coarse grain steamed bread was studied,and the processing index of coarse grain steamed bread was analyzed by principal component analysis.Results The optimum ratio of oats,buckwheat and quinoa was 85:20:59(m:m:m),which was close to the optimum amino acid model of human body.According to the reasonable ratio of grinding powder to study the process of coarse grain steamed bread,it was concluded that the best process was oats content 44.8%,quinoa content 10.5%,buckwheat content 31.2%,milling mesh 120,yeast consumption 1.5%,gluten consumption 12%(m:m),water content 90%(g:mL).Conclusion The quality of coarse grain steamed bread prepared with this formula is the best,which provides the theoretical basis and evaluation method for the production of coarse grain steamed bread,and provides data reference for the development and processing of coarse grain steamed bread.
