摘要 利用线性规划法优化以红小豆为主要原料的老年食品配方,并通过动物实验对其营养学进行评价。以红小豆、薏米、燕麦等杂粮为主要原料,根据老年食品的营养要求,在总能量、蛋白质、膳食纤维、钙、碳水化合物、脂肪等营养素组成和最低成本的约束条件下,建立数学模型进行优化。结果表明,红小豆82.5%、薏米5%、燕麦1%、大豆蛋白6.7%、天门冬氨酸钙2.8%、脱脂奶粉2%组成的老年食品,营养价值符合"四足四低"要求,而且成本最低,动物实验结果表明食用后血糖、血脂无明显差异,蛋白质和钙消化率提高。 A kind of geriatric food using red bean as the main raw material was obtained by the linear programming method. Its nutrition was evaluated through animal experiments. The formulation was composed of red beans,coix seed,oatmeal,etc. According to nutritional needs of total energy,protein,dietary fiber,calcium,carbohydrates,fats and other nutrients for the geriatric food,and the constraints on minimum cost,the formulation was optimized using a mathematical model. The results showed that the nutritional value could meet the requirements of ‘four enough and four low’and has the lowest cost when the ratios of red bean,coix seed,oatmeal,soy protein,calcium aspartate and skimmed milk powder were 82.5%,5%,1%,6.7%,2.8%and 2%,respectively. In addition,animal experiments showed that there was no significant difference in postprandial plasma glucose and lipids,while the digestibility of protein and calcium was improved.
