Embodiment 1
[0028] Step 1. Soak the early indica rice for 6-14h to make the early indica rice fully absorb water; soak the corn ballast for 8-16h; wash and peel the fresh potatoes and cut them into rice-sized pieces.
[0029] Step 2. Mix the pretreated rice, corn dregs and potato pieces and add them to the feeding hopper of the grinding and extrusion molding equipment, add water to cover the potato, rice, and corn dregs mixture by 3-5cm, and control the temperature to 80- Grinding and extruding at 85°C to obtain primary processed rice noodles.
[0030] Step 3: Put the preliminary processed rice noodles at 20-30°C for 10-16 hours for optimization, and obtain optimized rice noodles.
[0031] Step 4. The optimized rice noodles are dried in a medium temperature and high humidity multi-stage process. The method is: the optimized rice noodles are dried according to the following seven stages: the first stage: temperature 25°C, humidity 85%, drying time 60min; Stage: Temperature 30℃, humidity 85%, dry...

Abstract
The invention discloses a method for processing potato and corn composite nutritional rice flour. According to the method, fresh potatoes, corn dregs and rice are taken as raw materials, a grinding and extruding process and a medium-temperature high-humidity multistage drying method are combined, and the ratio of the fresh potatoes, the corn dregs and the rice and the temperature, optimized conditions and the like in the grinding and extruding process are controlled, so that not only can the nutritional ingredients of the potatoes and corns be fully maintained, and also the composite nutritional rice flour has the advantages of simple process, good taste and rich nutrition, and the method is suitable for large-scale industrial production of the potato and corn composite nutritional rice flour.
Description
Technical field [0001] The invention relates to the field of food processing, in particular to a processing method of potato and corn compound nutritional rice noodles. Background technique [0002] Potatoes have high nutritional value and are universally recognized as complete nutritious foods, which have attracted widespread attention and research. Generally speaking, fresh potatoes contain 9-20% starch, 1.5-2.3% protein, 0.1-1.1% fat, and 0.6-0.8% crude fiber. Potato protein has high nutritional value, high digestible components, and is easily absorbed by the human body. Its quality is similar to animal protein and comparable to eggs. Potato protein contains 18 kinds of amino acids, including arginine, histidine, isoleucine, lysine, methionine, phenylalanine, threonine, tyrosine, valine, etc. which cannot be synthesized by the human body. Essential amino acids. In addition, potatoes are also rich in vitamins, including carotene, vitamin C, thiamine, riboflavin, niacin, etc....
