Embodiment 1

[0018] Adopt the technical scheme of combining the end value of 0.1% of the solution concentration of amaranth solution in the independent right 1 and the second right.

[0019] A kind of technology of natural amaranth coloring rice, specifically comprises the following steps:

[0020] (1) Extraction of natural amaranth: Weigh a certain amount of red amaranth leaves, crush them, add distilled water to soak at room temperature for 4-5 hours according to the ratio of solid to liquid of 1:4, filter, let stand, collect the supernatant, concentrate and dry to obtain Amaranth.

[0021] (2) Husking: Husking with a hulling machine;

[0022] (3) Separation of rice and rice mixture: the husked brown rice is automatically transported to the gravity rice and rice separator for separation of rice and rice, and the clean brown rice is separated;

[0023] (4) Thickness classification: the clean brown rice is separated and screened by a thickness classifier to select broken grains and uncoo...

Abstract

The invention discloses a technology for coloring rice with natural amaranth. The technology comprises natural amaranth extracting and a rice processing technology, wherein the rice processing technology comprises the steps of hulling, unhulled rice and brown rice separating, thickness separating, rice milling, classifying, coloring, measurement packing and the like. The solution concentration of the natural amaranth for coloring the rice is 0.1-20%, the preferential range is 0.5-10%, and the optimum concentration is 2%. According to the technology for coloring the rice with the natural amaranth, the natural amaranth which can be resistant to lipid oxidation, free radical scavenging and bacterium is used for coloring the rice, the cost is reduced, the nutrition loss caused by polishing and other technologies is decreased, and in addition the rice nutrition is increased, so that the rice has attractive colors.

Description

technical field [0001] The invention relates to a process for coloring rice with natural amaranth. Background technique [0002] In order to improve the appearance quality of rice, it is necessary to color sort and polish the rice. Color sorting can remove some heterochromatic particles, but the color sorting machine is expensive; polishing, especially secondary polishing, will increase investment and have food hygiene and safety issues. [0003] Amaranth is a natural pollution-free green food, and it is cheap and easy to get. As an extract of amaranth, natural amaranth pigment has bright color, non-toxicity, natural coloring, high safety and stable properties. Amaranth has multiple functions such as anti-lipid oxidation, scavenging free radicals and antibacterial. Contents of the invention [0004] In order to solve the problems in the background technology, the present invention provides a process for coloring rice with natural amaranth, so that the processed rice can...
