Grain-bean type nutritional food formula and prepration process

The invention relates to a grain-bean type nutritional food formula and a prepration process, and the grain-bean type nutritional food formula is characterized in that the grain-bean type nutritionalfood formula comprises 4-20 parts of soybean flour, 3-20 parts of grain flour or rice flour and 1-2 parts of yeast. The preparation process is as follows: 1. an infant grain-bean type nutritional foodduring weaning period is prepared by taking 4 parts of soybean and 4-8 times of the weight of the soybean of water, evenly mixing, carrying out steam heating at normal pressure for 30 minutes and then cooling to 30-35 DEG C. Then, 3 parts of the grain flour or the rice flour are added in a fermentation tank for even mixing, 1.5 parts of beer yeast is further added, excipients are added after carrying out flowing aerobic fermentation for 6-8 hours at the temperature of 30-35 DEG C, and heating, curing and molding are carried out. Due to the elimination of anti-nutrition factors in a seed foodby using the method, the gr
