[0023] The embodiment of the present application provides a nutritious rice paste, which is made from the following raw materials in parts by weight: 70-80 parts of germ rice flour and 20-30 parts of rice germ powder.

[0024] like Figure 1 As shown, the nutritious rice paste is made by the following steps:

[0025] Step 1, medium-crushing the germ rice, wherein the mesh number of the germ rice after medium-crushing is not greater than 12 meshes;

[0026] Step 2: adding rice germ to the germ rice after medium crushing according to the above proportion, mixing evenly, and subjecting the mixture to high-pressure puffing and maturation treatment;

[0027] Step 3: Use a pulverizer to crush the cooked mixture, the mesh size of the pulverization is not greater than 100 meshes, and obtain nutritious rice paste.

[0028] The above-mentioned nutritious rice paste is made of germ rice and pure germ. The germ contains a variety of vitamins and minerals, such as vitamin B1, vitamin B2, niacin, calcium, iron, zinc, etc., which are beneficial to human health; and the presence of these nutrients in rice paste can help meet the human body's needs for vitamins and minerals. Germ rice contains a certain amount of protein. After processing, the digestion and absorption rate of protein in rice paste is improved, which is very important for physical development and health maintenance, especially providing sufficient nutrition for the growth of infants and muscle maintenance of the elderly.

[0029] In one embodiment, the preparation of the nutritious rice paste further comprises step 4, wherein the nutritious rice paste is subjected to microwave sterilization, and then enters the pre-packaging silo for packaging. The working parameters of microwave sterilization are irradiation with ultraviolet light for 5 to 15 minutes at a temperature of 145° C. to 155° C. The source of ultraviolet light can be an ultraviolet lamp or other equipment that provides ultraviolet light.

[0030] In one embodiment, step 1, medium-crushing the germ rice comprises:

[0031] 1) The germ rice is crushed by a gear crushing device, the gear speed is 2500-3100 rpm, and the flow rate of the germ rice is 15-20 kg / min;

[0032] 2) The crushed germ rice is sieved, and the mesh number of the germ rice is not greater than 12 meshes.

[0033] In one embodiment, a gear mill is used to crush the cooked mixture, the gear speed is 2500-3100 rpm, the flow rate of the germ rice is 3-5 kg / min, and the mesh size of the crushing is not more than 100 meshes to obtain nutritious rice paste.

[0034] In one embodiment, the mixture is subjected to a high pressure puffing and cooking process, comprising:

[0035] The screw puffing equipment is used to perform extrusion puffing at a temperature of 145° C.-155° C., a screw speed of 150 r / min, a feed rate of 8 kg / h, and a shear speed of 200 r / min to obtain a cooked mixture.

[0036] In one embodiment, the weight of the germ accounts for 3% to 5% of the whole germ rice.

[0037] Rice germ can be purchased directly or obtained by threshing rice. For example, the following steps can be used to extract rice germ:

[0038] Step 1: Prepare unwashed rice: dry the mature rice and then process it into unwashed rice. The germ-preserving rice machine is a two-pass BSPB sand roller modified germ-preserving rice mill plus a DRPH modified polishing bran-wiping rice mill, which grinds out unwashed rice and rice bran containing some accidentally fallen rice germ particles;

[0039] Step 2: Prepare rice meal: The unwashed rice obtained in step 1 is further ground by three DRPA-D, DRPA-DW and DRPH iron roller rice mills to obtain clean rice meal, so that most of the rice germ and aleurone layer are separated from the rice grains;

[0040] The third step is separation of germ and aleurone layer: the rice meal obtained in the second step is firstly separated into rice bran and rice germ by air selection using a KXFD30 type meal separator in a pneumatic conveying pipeline, and then the rice meal after air selection is fully screened by a DZ100 type rotary vibrating screen with a screen mesh of 28 meshes to separate the rice germ and aleurone layer powder;

[0041] Step 4: Extracting rice germ: The rice germ obtained in the third step is selected and purified by an MPFX42 germ separator and an RD-C multifunctional CCD color sorter to obtain pure rice germ.

[0042] Germ rice can be commercially available germ rice or obtained by grinding rice grains. For example, the following steps can be used to extract germ rice:

[0043] The first step is to put the brown rice in an upright state downward between a pair of high-speed rotating grinding wheels, with the width direction of the brown rice parallel to the axis direction of the two grinding wheels; the movement direction of the adjacent wheel rims of the two grinding wheels is downward;

[0044] In the second step, the brown rice grains are rolled into the narrow gap between the rims of the two grinding wheels, and the aleurone layer and / or the outer blank milk coated on the side surface of the middle section are ground off;

[0045] Step 3: The rice grains fall out of the narrow gap between the rims of the grinding wheel to obtain germ rice.

[0046] Example 1

[0047] A nutritious rice paste is prepared from the following raw materials in parts by weight: 80 parts of germ rice flour and 20 parts of rice germ powder. The weight range of the germs in the whole germ rice is 4%.

[0048] like Figure 1 As shown, the nutritious rice paste is made by the following steps:

[0049] Step 1: medium-crushing the germ rice, wherein the mesh number of the germ rice after medium-crushing is not greater than 12 meshes.

[0050] 1) The germ rice is crushed by a gear crushing device, the gear speed is 2500 rpm, and the flow rate of the germ rice is 15 kg / min;

[0051] 2) The crushed germ rice is sieved, and the mesh number of the germ rice is not greater than 12 meshes.

[0052] Step 2: adding rice germ to the medium-crushed germ rice according to the above proportion, mixing evenly, and subjecting the mixture to high-pressure puffing and maturation treatment.

[0053] The screw puffing equipment is used to perform extrusion puffing at a temperature of 145° C., a screw speed of 150 r / min, a feed rate of 8 kg / h, and a shear speed of 200 r / min to obtain a cooked mixture.

[0054] Step 3: Use a pulverizer to crush the cooked mixture, the mesh size of the pulverization is not greater than 100 meshes, and obtain nutritious rice paste.

[0055] The cooked mixture was crushed by a gear crusher, the gear speed was 3100 rpm, and the flow rate of the germ rice was 5 kg / min.

[0056] The nutritional rice paste prepared in Test Example 1 has the following test results:

[0057] Energy is 1700kJ / 100g; dietary fiber is 5.7g / 100g; protein is 11.6g / 100g; vitamin B1 is 2.07mg / 100g; vitamin B2 is 0.33mg / 100g; niacin is 0.86mg / 100g; calcium (as Ca) is 20mg / 100g; iron (as Fe) is 3.6mg / 100g; zinc (as Zn) is 3.96mg / 100g; selenium is 4.8μg / 100g; γ-aminobutyric acid is 42.2mg / 100g.

[0058] It can be seen from the above data that the nutritious rice paste prepared in this embodiment has high nutritional value and comprehensive nutrition.

[0059] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed in the present application should be included in the protection scope of the present application.
