Problems solved by technology

This kind of fortified rice has little nutrient loss during storage, transportation and sales, but the production process has high energy consumption, large investment, and high production cost, so it is not suitable for rice processing enterprises in my country.
In addition, the nutrient-enhanced rice prepared by the existing technology has average cooking quality and poor taste, so it is difficult to be accepted by consumers.

Embodiment 1

[0022] (1) Soak the rice in 1.1% (w / v) sodium bicarbonate aqueous solution for 2 hours for pretreatment, remove and dry, crush and pass through a 120-mesh sieve to obtain rice flour;

[0023] (2) Weigh 50kg of rice flour, add 5kg of corn flour, mix well, add 0.38 mg of sodium selenite per kilogram of mixed flour, slowly add sodium selenite solution, stir to mix evenly, and adjust the mixing powder The moisture content is 23%, transferred to a single-screw extruder, the temperature of the fifth stage of the screw is set to 35°C-70°C-90°C-85°C-50°C, the feeding speed is 32r / min, and the screw speed is 16Hz. After extrusion, use a rotary cutter to cut into the shape of rice grains, place them under the conditions of 43°C and 72% humidity for slow aging for 4 hours, and then put them in a drying oven at 55°C to dry and polish to obtain nutritious rice rich in organic selenium.

Embodiment 2

[0026] (1) Soak the rice in 0.8% (w / v) sodium bicarbonate aqueous solution for 2 hours for pretreatment, remove and dry, crush and pass through a 120-mesh sieve to obtain rice flour;

[0027] (2) Weigh 50kg of rice flour, add 7kg of corn flour, mix well, add 0.38 mg of sodium selenite solution per kilogram of mixed flour, slowly add sodium selenite solution, stir to mix evenly, and adjust the mixing powder The moisture content is 23%, transferred to a single-screw extruder, the temperature of the fifth stage of the screw is set to 35°C-70°C-90°C-85°C-50°C, the feeding speed is 30r / min, and the screw speed is 16Hz. After extrusion, use a rotary cutter to cut into the shape of rice grains, place them under the conditions of 43°C and 72% humidity for slow aging for 4 hours, and then put them in a drying oven at 55°C to dry and polish to obtain nutritious rice rich in organic selenium.

Embodiment 3

[0030] (1) Soak the rice in 0.5% (w / v) sodium bicarbonate aqueous solution for 2 hours for pretreatment, remove and dry, crush and pass through a 120-mesh sieve to obtain rice flour;

[0031] (2) Weigh 50kg of rice flour, add 3kg of corn flour, mix well, add 0.30 mg of sodium selenite per kilogram of mixed flour, slowly add sodium selenite solution, stir to mix evenly, and adjust the mixing powder The moisture content is 23%, transferred to a single-screw extruder, the temperature of the fifth stage of the screw is set to 35°C-70°C-90°C-85°C-50°C, the feeding speed is 32r / min, and the screw speed is 16Hz. After extrusion, use a rotary cutter to cut into the shape of rice grains, place them under the conditions of 43°C and 72% humidity for slow aging for 4 hours, and then put them in a drying oven at 55°C to dry and polish to obtain nutritious rice rich in organic selenium.

Abstract

The invention discloses a method for producing nutrient rich in selemium. The method comprises the following steps: mixing pretreated rice meal with corn meal with a certain proportion uniformly; adding sodium selenite, regulating the content water in the mixed meals; transferring the mixed meals to a single-screw extrusion machine to extrude; cutting the mixed meals into rice grain shape by using a rotary cutter; putting the rice grains at constant temperature and humidity to temper and age; and then drying and polishing, thus obtaining the nutrient rich in selemium. The nutrient rich in selemium is good in cooking quality, and can be contributed to eliminating peroxides and radicals in the bodies of customers in regions with selenium deficient soils, so cells are prevented from being damaged; and moreover, the tumor growth is inhibited, and the body immunity is improved.

Description

technical field [0001] The invention relates to a method for preparing nutritious rice rich in organic selenium, in particular to a method for preparing nutritious rice rich in organic selenium by using a screw extrusion technology, which belongs to the technical field of food processing. Background technique [0002] As a major food crop, rice is widely planted around the world and is a very important source of food for human beings. According to the statistics of the Food and Agriculture Organization of the United Nations, there are 122 countries in the world that grow rice, and the annual planting area reaches 140-157 million hectares, accounting for about 23% of the grain planting area; the total output of rice is about 600 million tons, accounting for about 29% of the total grain output ; There are more than 50 countries with an annual output of more than 100,000 tons of rice. Among the top ten rice producing countries in the world, all are in Asia except Brazil, with ...
