Problems solved by technology

[0002] There are many kinds of rice on the market, but the existing rice production methods often cause the chlorophyll in the rice to be decomposed and lost to a large extent, thereby greatly reducing the chlorophyll content of the rice itself

Embodiment Construction

[0012] The present invention will be further described in detail below in conjunction with examples.

[0013] A production method of chlorophyll rice, comprising the following steps:

[0014] S1. Harvesting in advance: when the paddy is not completely yellow and the grain moisture content of the paddy is 18%-19%, the paddy is harvested in advance to obtain the grain;

[0015] S2. Low-temperature drying: dry the grains obtained in S1 at a temperature of 46-52°C (do not use the sun to dry, as sunlight will accelerate the decomposition and loss of chlorophyll in the grains);

[0016] S3. Hulling and rice milling: hulling the grains dried at low temperature in S2 to obtain brown rice, and then using a rice mill to peel and whiten the brown rice to obtain the chlorophyll rice.

[0017] The grains obtained in S1 need to be dried at low temperature within 1-1.5 h after harvesting.

[0018] The drying time at low temperature in S2 is 2.5-4 hours.

[0019] The moisture content of th...

Abstract

The invention provides a production method of chlorophyll rice which comprises the following steps of 1, early harvest, when the rice is not completely yellow and the moisture content of rice grains is between 18% and 19%, the rice is harvested in advance to obtain the grains; 2, drying at a low temperature, the grains obtained in step 1 are dried at a low temperature of 46 to 52 DEG C; and 3, shelling and milling, the low-temperature dried grains from step 2 are shelled to obtain brown rice, the brown rice is shelled and whitened by using a rice milling machine to obtain the chlorophyll rice.The rice is harvested when the rice is not completely yellow and the moisture content of the rice grain is 18% - 19%, the obtained rice grains are dried at a low temperature of 46-52 DEG C within 1-1.5 hours after harvest, the decomposition loss rate of chlorophyll in the rice can be effectively reduced, the chlorophyll content of every kilogram of chlorophyll rice finally obtained reaches 6.7-20mg, and therefore the edible value of the rice is greatly improved.

Description

technical field [0001] The invention relates to the grain field, in particular to a production method of chlorophyll rice. Background technique [0002] There are many kinds of rice on the market at present, but the existing rice production methods often cause the chlorophyll in the rice to be decomposed and lost to a large extent, thereby greatly reducing the chlorophyll content of the rice itself. Contents of the invention [0003] Aiming at the deficiencies in the above technologies, the present invention provides a method that can greatly reduce the decomposition and loss of chlorophyll contained in rice itself, thereby increasing the chlorophyll content of rice. [0004] A production method of chlorophyll rice, comprising the following steps: [0005] S1. Harvesting in advance: when the paddy is not completely yellow and the grain moisture content of the paddy is 18%-19%, the paddy is harvested in advance to obtain the grain; [0006] S2, low-temperature drying: dry...
