Abstract

The invention relates to a production method of nutrient seven-color fruit and vegetable steamed stuffed buns, and belongs to the technical field of food processing. The production method comprises the following technological steps of making freeze-dried fruit and vegetable powder; selecting flour raw materials; activating the selected flour materials with dry yeast; adding fruit and vegetable powder; adding other raw materials; kneading the flour, the fruit and vegetable powder and other raw materials so as to obtain dough; performing fermentation for the first time; performing fermentation for the second time; preparing filling materials; wrapping the filling materials, and shaping steamed stuffed buns; performing fermentation; and steaming the steamed stuffed buns after the fermentation. The production method disclosed by the invention has the following advantages that the advantages of conventional fermented cooked wheaten foods are furthest reserved, bran-new product appearances and unique flavor are given to the steamed stuffed buns, and the nutrient value of the steamed stuffed buns is higher; new techniques for modern food processing and product analysis, including a fermentation technique, a freeze drying technique, an ultramicro pulverization technique, a mixed flour milling technique, a flour quality analyzing technique, a texture profile analysis technique and the like, are adopted in the production method disclosed by the invention, so that the technical content of the steamed stuffed bun industry is increased; the steamed stuffed buns are nutrient, health-care, attractive in color, unique in flavor, convenient and ready-to-eat, and have good market prospects.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a production method of a fruit and vegetable nutrition colorful bag. Background technique [0002] Steamed buns are one of the traditional noodles of the Han nationality in China. According to legend, they were invented by Zhuge Liang during the Three Kingdoms period (more than 1800 years ago). The use of the name "Baozi" began in the Song Dynasty. "Yimou Lu of Yanyi": "On the birthday of Renzong, the ministers will be given buns." Steamed buns are generally made of flour fermented, and the size varies according to the size of the filling. The smallest can be called Xiaolongbao, and the others are medium buns and large buns. Most of the existing steamed buns on the market are mainly white and soft, with a single appearance and color, and the nutrition of ordinary dough is also limited. In recent years, my country has vigorously promoted the importance of hea...
