Embodiment 1

[0016] (1) Slowly add the acidic solution by atomization until the water content of germinated brown rice is 25%, keep the water addition rate at 0.6% / hour before the water content reaches 17%, and slowly increase the water addition rate to 1.0% / hour after the water content exceeds 17%; (2) The germinated brown rice is slowed down for 3 hours at 40°C and the humidity is 95%; (3) The germinated brown rice is treated with far-infrared rays, the temperature of the infrared heat source is 200°C, and the treatment time is 6 minutes; (4) 3% Using citric acid as a solvent, prepare a chitosan solution with a mass percentage of 2%, spray the germinated brown rice treated with far-infrared rays, and dry it in air at 45°C to form a transparent and bright protective film. The germinated brown rice is vacuum-packed after the above-mentioned treatment.

Embodiment 2

[0018] (1) Slowly add the acidic solution by atomization until the water content of brown rice is 23%, maintain the water addition rate of 0.6% / hour before the water content reaches 17%, and slowly increase the water addition rate to 0.9% / hour after the water content exceeds 17%; ( 2) Brown rice is cured for 2.5 hours at 35°C and humidity 80%; (3) Treat brown rice with far-infrared rays, the temperature of the infrared heat source is 180°C, and the treatment time is 10 minutes; (4) Use 2.5% citric acid As a solvent, a chitosan solution with a mass percentage of 1.5% was prepared, sprayed on brown rice treated with far-infrared rays, and dried in air at 43°C to form a transparent and bright protective film. The brown rice is vacuum-packed after the above-mentioned treatment.

Embodiment 3

[0020] (1) Slowly add the acidic solution by atomization until the water content of the semi-brown rice is 20%, keep the water addition rate at 0.6% / hour before the water content reaches 17%, and slowly increase the water addition rate to 0.8% / hour after the water content exceeds 17%; (2) Semi-brown rice is cured for 2 hours at 30°C and humidity 75%; (3) Semi-brown rice is treated with far-infrared rays. The temperature of the infrared heat source is 150°C, and the treatment time is 14 minutes; (4) Use 2% Using citric acid as a solvent, prepare a chitosan solution with a mass percentage of 1%, spray it on the semi-brown rice treated by far-infrared rays, and dry it in the air at 40°C to form a transparent and bright protective film. The semi-brown rice is vacuum-packed after the above-mentioned treatment.

Abstract

The invention relates to a production method of washing-free cooking rice. The production method is characterized by comprising the following steps of slowly adding an acid solution in an atomizing manner, performing tempering for some time, then performing irradiation by low-heat source far infrared rays, so as to activate enzymes in rice step by step; and besides, evaporating free water in the rice, so as to obtain the washing-free rice having good cooking properties. According to the production method disclosed by the invention, slow humidifying by an atomizing method and low-temperature high-moisture tempering treatment are adopted, so that the crossbreaking rate of rice granules is effectively reduced, and loss of nutrient components is reduced.

Description

technical field [0001] The invention relates to a production method of steamed and boiled rice without scouring, and belongs to the field of agricultural product processing. Background technique [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, semi-brown rice and germinated brown rice with better nutritional value are advocated. However, because these rices contain a lot of crude fiber and bran layers, their cooking performance and eating quality are not good, which is an unfavorable factor restricting their promotion. [0003] Far infrared is a kind of ray with strong heating effect. Under the action of far-infrared rays, the dipoles and free charges in organisms tend to be arranged in the direction of the electromagnetic field. In the process, the irregular motion of molecules and atoms is aggravated to generate heat; when the far-infr...
