Problems solved by technology

[0002] There are many kinds of rice on the market, but the existing rice planting and production methods are often harvested after maturity, which causes the chlorophyll in the rice to be decomposed and lost to a large extent, thereby greatly reducing the chlorophyll content of the rice itself
At the same time, the paddy that produces rice is easily polluted by heavy metals in the soil and irrigation water during the planting process, which reduces the eating quality of rice.

Embodiment 1

[0026]A production method of pollution-free chlorophyll rice includes the following steps:

[0027]S1. Paddy planting and harvesting: Choose field soil that does not contain heavy metals for rice planting, apply organic fertilizers during the rice growth period, and use water sources that meet the national surface water secondary water standards for irrigation. No chemical fertilizers and pesticides are applied. When the rice is not completely yellow When the moisture content of the rice grains is 18%, the rice grains are harvested to obtain grains, and the grains do not fall to the ground during harvesting;

[0028]S2. Low temperature cleaning and drying: the obtained grains are cleaned at a temperature of 18°C, the impurity content of the grains after cleaning is 0.2%, and the grains after cleaning are dried at 38°C to reach the grain The moisture content of the grain is 12%, and the cleaning and drying of the grain must be completed within 4 hours after harvest;

[0029]S3. Low-temperatur...

Embodiment 3

[0048]S1. Paddy planting and harvesting: Choose field soil that does not contain heavy metals for rice planting. During the rice growth period, apply organic fertilizer and use water sources that meet the national surface water secondary water standard for irrigation. No chemical fertilizers and pesticides are applied. When the rice is not completely yellow When the moisture content of the rice grains is 18.5%, the rice grains are harvested to obtain grains;

[0049]S2, low-temperature cleaning and drying: the obtained grains are cleaned at a temperature of 26°C, the impurity content of the grains after cleaning is 0.25%, and the grains after cleaning are dried at a temperature of 44°C to The moisture content of the grain is 12.5%, and the cleaning and drying of the grain must be completed within 4.5h after harvest;

[0050]S3. Low-temperature storage in warehouse: send the dried grains to the grain warehouse at 10℃ for storage;

[0051]S4. Hulling and rice milling: the grains stored in the ...

Abstract

A production and preparation method of pollution-free chlorophyll rice, comprising the following steps: S1, paddy planting and harvesting: selecting field soil free of heavy metals for paddy planting, and harvesting the paddy until the paddy is not completely yellow to obtain grains; S2, low temperature Cleaning and drying: clean the obtained grains at a temperature of 18-35°C; S3, storage at low temperature in warehouse; S4, husking and milling to obtain brown rice; S5, one-time husking to obtain primary rice; S6, two The second bran removal is to obtain second-grade rice; S7, the third bran removal, removes the remaining rice bran layer, and obtains chlorophyll rice. The invention can effectively reduce the rate of decomposition and loss of chlorophyll in the rice, and the finally obtained chlorophyll content per kilogram of chlorophyll rice reaches 24-50 mg, which greatly improves the edible value of the rice itself.

Description

Technical field[0001]The invention relates to the field of food, in particular to a method for producing pollution-free chlorophyll rice.Background technique[0002]At present, there are many kinds of rice on the market, but the existing rice planting and production methods are often harvested after mature, which makes the chlorophyll in the rice decompose and lose to a large extent, thereby greatly reducing the chlorophyll content of the rice itself. At the same time, rice-producing rice is susceptible to heavy metal pollution in the soil and irrigation water during the planting process, which reduces the eating quality of rice.Summary of the invention[0003]In view of the shortcomings in the above-mentioned technology, the present invention provides a method that can greatly reduce the decomposition and loss of chlorophyll contained in the rice itself, thereby increasing the chlorophyll content of the rice.[0004]A production method of pollution-free chlorophyll rice includes the foll...
