高粱营养粥的研制及其品质分析

Preparation and Quality Analysis of Sorghum Nutritional Porridge

以高粱、糯米、红米和黑米为主原料,感官评分为评价指标,通过单因素和正交试验确定高粱营养粥的最优配方,将其口腔消化率与市售银鹭黑米粥进行进行对比分析。结果表明,高粱营养粥最优配方为:高粱、糯米、红豆、黑米比例为7∶6∶6∶1,料液比为1∶12,煮制时间为90 min,三聚磷酸钠的添加量为0.08%,白砂糖的添加量为2%,蔗糖脂肪酸酯的添加量为0.12%;研制的高粱营养粥能量331.6 KJ·100 g^(-1),蛋白质含量1.1 g·100 g^(-1),脂肪含量0.6 g·100 g^(-1),碳水化合物含量17.1 g·100 g^(-1);整个口腔消化阶段高粱营养粥消化率均高于银鹭黑米粥,消化120 min后两者的消化率差距显著,此时间点高粱营养粥和银鹭黑米粥的碳水化合物消化率分别为16.05%和12.10%,180 min后均达到最大,分别为19.95%,18.36%。研制的高粱营养粥具有营养丰富、口味独特、易于消化等优良特点,研究拓宽了高粱的应用加工范围。

Optimal formulation of sorghum nutrient porridge with the addition of glutinous rice,red rice and black rice was produced by the single and orthogonal tests and compared with the commercial Yinlu porridge with the oral digestibility.The results showed that the optimal formula of sorghum nutrition porridge was:the respective ratio of sorghum,glutinous rice,red beans and black rice was 7∶6∶6∶1,ratio of material to liquid was 1∶12,cooking time was 90 min.Addition of sodium triphosphate was 0.08%,white granulated sugar was 2%,sucrose fatty acid ester was 0.12%.Under those condition,the energy of sorghum nutrient porridge was 331.6 KJ·100 g^(-1),protein content was 1.1 g·100 g^(-1),fat content was 0.6 g·100 g^(-1),carbon content was 17.1 g·100 g^(-1).The digestive rate of sorghum nutritional porridge was higher than that of Yinlu porridge during the whole oral digestion stage.The digestibility difference between two porridges was significant after 120 min of digestion,the carbohydrate digestibility of sorghum nutrient porridge and Yinlu porridge was 16.05% and 12.10%,respectively.After 180 min of digestion,those reached to 19.95% and 18.36%.A sorghum nutrient porridge with rich nutrition,unique taste and easy to digest was studied in present research,broadened the application and processing scope of sorghum.
