Abstract:This article used linear programming to design cereals with high dietary fiber.Wheat flour，bean curd powder，barley flour，buckwheat flour and whole wheat flour were used as raw materials，and the dietary fiber content which was not less than 10%was used as the main constraint during the linear solution.The nutrient composition analysis and cooking performance of the obtained formula were carried out to determine the optimal formula.Dietary fiber content of the formula which acquired from linear programming up to 10%or more and protein content increased by nearly 3%.What's more，the compound powder had a functional component-Rutinum and its content was 120.93 mg/g.The steamed bread had a better taste and higher nutritional value with this formula steamed.
