Embodiment Construction
[0013] The present invention will be described in further detail below, so that those skilled in the art can implement it with reference to the description.
[0014] The invention provides a processing method of potato nutrient compound rice, comprising: step 1), mixing evenly 70 parts of rice flour, 30 parts of potato whole flour and 10 parts of corn flour in parts by mass, wherein rice flour, potato whole flour The thickness of rice flour and corn flour are 90 mesh, 100 mesh and 90 mesh respectively; among them, the rice flour used is made from early indica rice or broken rice, which helps to expand the application range of early indica rice or broken rice. Potato powder is used in compound rice to improve the taste of early indica rice and improve product quality;
[0015] Step 2), send the mixed raw materials into the twin-screw extrusion molding equipment, and extrude to obtain the semi-finished product of potato nutrition compound rice. Six heating zones, the heating te...

Abstract
The invention discloses a processing method of nutritional potato mixed rice. The processing method comprises the following steps: uniformly mixing 70-90 parts of rice meal, 10-30 parts of mashed potato and 10-20 parts of corn flour in parts by mass, wherein the finenesses of the rice meal, the mashed potato and the corn flour are respectively 70-90 meshes, 100-150 meshes and 70-120 meshes; feeding the mixed raw materials into a double-screw extrusion forming device, wherein the double-screw extrusion forming device is divided into six heating regions, and the heating temperatures from a first region to a sixth region are respectively 20-25 DEG C, 50-60 DEG C, 90-100 DEG C, 100-115 DEG C, 110-115 DEG C and 85-95 DEG C; cooling for 1-2 hours by virtue of a cooling fan, and drying at 20-30 DEG C for 4-6 hours, so as to obtain the finished nutritional potato mixed rice. According to the processing method of the nutritional potato mixed rice, by adding the mashed potato into mixed rice, the taste of the mixed rice is improved, the consumption of potatoes is increased, the development of potato industries is promoted, and the food security is guaranteed.
Description
technical field [0001] The invention relates to a processing method of potato nutrient compound rice. Background technique [0002] Potato has high nutritional value and is a globally recognized complete nutritional food. Its protein has high nutritional value, high digestible components, and is easily absorbed by the human body. Its quality is similar to animal protein and contains 18 kinds of amino acids, including arginine, Amino acid, isoleucine, lysine, methionine, phenylalanine, threonine, tyrosine, valine and other essential amino acids that the human body cannot synthesize by itself, which are comparable to eggs. At the same time, potatoes are also rich in vitamins (carotene, vitamin C, thiamine, riboflavin, niacin, etc.) and minerals (such as calcium, phosphorus, iron, etc.) and other nutrients. In European and American countries, the output and consumption of processed potato products account for about 76% of the total output, and there are more than 90 kinds of p...
