Embodiment 1

[0030] combine figure 1 It can be seen that brown rice and grain amaranth grains are ground by vertical cyclone mill to obtain brown rice flour and grain amaranth powder respectively, and the gained brown rice flour and grain amaranth powder are passed through a 100 mesh sieve respectively, and 60.5 g of sieved brown rice flour and 39.1 g of sifted brown rice powder are taken. After the sieved grain amaranth powder is mixed evenly, add 0.4g monoglyceride as a modifier, mix evenly to obtain 100g compound powder, send the compound powder into the hopper of a twin-screw extruder, and extrude and cut For granulation, the production process parameters of controlled twin-screw extrusion are: solid feed rate 10kg / h, liquid feed rate 19.5%, and barrel temperature of 40-160°C (the temperatures of the five temperature zones are respectively T1: 70°C, T2: 140°C, T3: 150°C; T4: 80°C; T5: 60°C), the screw speed is 120r / min, the cutting machine speed is 800r / min; the prepared rice grains ar...

Embodiment 2

[0032] Brown rice and grain amaranth grains are ground respectively by vertical cyclone mill to obtain brown rice flour and grain amaranth powder, and the gained brown rice flour and grain amaranth powder pass through a 100 mesh sieve respectively, and 85 g of sieved brown rice flour and 14.5 g of sieved After the grain amaranth powder is mixed evenly, add 0.5g of monoglyceride as an improver, mix evenly to obtain 100g of compound powder, send the compound powder into the hopper of a twin-screw extruder, extrude, cut and granulate, Among them, the control parameters of the twin-screw extrusion production process are: solid feed rate 12kg / h, liquid feed rate 20.5%, and barrel temperature of 40-160°C (the temperatures of the five temperature zones are respectively T1: 65°C, T2: 135°C, T3: 145°C; T4: 75°C; T5: 55°C), the screw speed is 140r / min, the cutting machine speed is 1000r / min; the prepared rice grains are transported to the fluidized bed through the connecting pipe by the ...

Abstract

The present invention discloses amaranthus hypochondriacus recombinant rice and belongs to the field of food processing. The recombinant rice is prepared from 60.5-95% of brown rice flour, 4.7-39.1% of amaranthus hypochondriacus powder and 0.1-0.5% of an additive. The present invention also discloses a production method of the amaranthus hypochondriacus recombinant rice. The method comprises the following steps: the brown rice flour and amaranthus hypochondriacus powder are used as main raw materials, a twin screw extruding technology is used, and gelatinizing, squeezing, extruding, cutting and granulating, fluidized bed pre-drying, microwave drying and other processes are carried out. In the squeezing process, the temperature in a machine barrel is divided into five temperature zones and the temperature control of each of the temperature zones is different. In the microwave drying stage, the microwave intensities in different zones are different. The prepared recombinant rice by the preparing technology is bright in color and luster, and moderate in mouthfeel, lysine is strengthened, nutrition is more balanced and reasonable, and the cost is lower.

Description

technical field [0001] The invention belongs to the field of food processing, and in particular relates to a grain amaranth recombined rice and a production method thereof. Background technique [0002] Grain amaranth is a new type of grain and feed crop. The amino acid composition in the protein of grain amaranth is balanced, especially the content of lysine is high. However, most cereals such as wheat and rice lack lysine, so that the food The nutritional value is affected, and lysine is easily destroyed and lacking in the process of processing. Therefore, supplementing some essential amino acids such as lysine in food as much as possible has become one of people's requirements for food quality; The caryopsis behind the outer protective cortex husk is rich in various nutrients, including dietary fiber and various minerals. The nutritional value of brown rice is higher than that of refined rice, but because the surface of brown rice contains part of the cortex, brown rice a...
