[0079] A preparation method for instant multi-grain nutritional granule supplementary food for infants, comprising the following steps:
[0080] (1) According to the ratio of 80% of triticale flour, 8.37% of black rice flour, 11.36% of black bean flour and 0.27% of black sesame flour, the raw materials were mixed and added with water, and then stirred for 10-25min to make the mixture evenly, and the mixed material was obtained. The water content of the mixed material is 24-28wt%.
[0081] (2) Extrusion and puffing: Extrude and puff the mixed material in step (1) at an extrusion temperature of 160-170° C. and a screw speed of 7-13 Hz to obtain an expanded mixed material.
[0082] (3) Drying: the puffed mixture in step (2) is made into a granular material of 0.45-0.9mm through a granular food supplement forming device, and then the granular material is dried at 50-70°C for 6- After 10 hours, the granule food supplement was obtained.
[0083] According to the three-factor three...

[0105] According to the ratio of 80% of triticale flour, 8.37% of black rice flour, 11.36% of black bean flour and 0.27% of black sesame flour, the mixture was mixed with water until the water content was 24wt%, and stirred for 15 minutes. Put the uniformly stirred mixture into the extrusion extruder, extrusion conditions: extrusion temperature 165 ° C, screw speed 10Hz, to obtain the puffed mixture, the puffed mixture is made into granular material through a molding device, and then the obtained The granular material was dried at 65° C. for 8 hours to obtain a granular food supplement with a particle size of 0.45-0.9 mm. According to the above measurement method, the gelatinization degree of the granular food supplement is 94.63%, the rehydration rate is 5.05%, the digestibility is 92.89%, and the comprehensive score is 192.57.
[0106] Adopt the following method to test the nutrient composition of embodiment 16 gained granule complementary food:
[0107] Refer to GB 5009.5-...
