Embodiment 1

[0017] Classify the brown rice according to the rice grain type, put the classified brown rice on the conveyor belt, the conveying speed is 1 kg / s, use saturated steam and air to treat the surface of the brown rice alternately, then lightly grind (the spindle speed is 800 rpm), and leave it at room temperature Store at 25±3°C, 65±3% RH. The alternate treatment of saturated steam and air is as follows:

[0018] (1) Preheat the brown rice with air, the air temperature is 50°C, the humidity is 40%, the flow rate is 2 m / s, and the action time is 40 seconds; (2) The brown rice is treated with saturated steam, and the steam temperature is 100 ℃, the flow rate is 2 m / s, and the action time is 20 seconds; (3) the brown rice is cooled by air, the air temperature is 50 °C, the humidity is 60%, the flow rate is 2 m / s, and the action time is 20 seconds; ( 4) Treat the brown rice with saturated steam, the steam temperature is 100°C, the flow rate is 2 m / s, and the action time is 20 second...

Embodiment 2

[0020] Classify the brown rice according to the rice grain type, put the classified brown rice on the conveyor belt, the conveying speed is 1.5 kg / s, use saturated steam and air to alternately treat the surface of the brown rice, then lightly grind (the spindle speed is 800 rpm), and place at room temperature Store at 25±3°C, 65±3% RH. The alternate treatment of saturated steam and air is as follows:

[0021] (1) Treat the brown rice with air, the air temperature is 60°C, the humidity is 50%, the flow rate is 3 m / s, and the action time is 30 seconds; (2) The brown rice is treated with saturated steam, the steam temperature is 100°C , the flow rate is 3 m / s, and the action time is 40 seconds; (3) the brown rice is processed by air, the air temperature is 40°C, the humidity is 40%, the flow rate is 35 m / s, and the action time is 40 seconds; (4 ) Treat the brown rice with saturated steam, the steam temperature is 100°C, the flow velocity is 3 m / s, and the action time is 40 secon...

Abstract

The invention relates to a production method for long-storage enriched rice. The production method is characterized by comprising the following steps of: classifying unpolished rice, adopting saturated steam and air to alternatively treat the unpolished rice; and carrying out primary light grinding to obtain the long-storage enriched rice. The enriched rice produced by the production method provided by the invention has a low crack percentage, loses a few nutritional ingredients, and can kill worm eggs hidden in the rice, can passivate lipoxidase and lipase in the rice, and can restrain lipid oxidation. Meanwhile, in the alternative treatment process of the saturated steam and the air, part of steam enters the coat of the unpolished rice, so that the coat and seed coat on the surface layer of the unpolished rice are easily removed by primary light grinding while an aleurone layer and a plumule part are kept. The enriched rice produced by the method is long in storage period and high in nutritional value.

Description

technical field [0001] The invention relates to a production method of nutritious rice, in particular to a production method of storage-resistant nutritious rice. technical background [0002] With the improvement of living standards, people pay more and more attention to healthy, nutritious and balanced diet. In Europe, America, Japan and other countries, brown rice with better nutritional value is advocated. However, brown rice has not been widely accepted because it contains more crude fibers and bran layers, has poor expansibility and water absorption, and has a bad taste. However, after proper processing of brown rice, the nutritious rice (reduction rate of 2%-8%) can be obtained by removing the cortex of brown rice and retaining the aleurone layer and germ. Since part of the bran layer is removed from nutritious rice, it tastes better than brown rice and contains more nutrients than polished white rice. However, after the bran layer is removed, the aleurone layer in...
