Abstract

The present invention relates to grains product, and is especially high nutritious rice or 'coarse rice', which is produced with paddy and through light grinding, dry air polishing to eliminate rice hull and 5-20 % of rice coating, and packing in airtight container filled with O2, CO2 and N2 in the weight ratio of 1-3 to 6-8 to 22-26. The high nutritious rice has well preserved bioactivity and nutrients of rice, good taste and preservation period over 10 months.

Description

High nutrient fresh-preservation rice

Technical field

The present invention relates to grain processing, preservation technique and manufactured goods thereof.

Background technology

Rice is human topmost cereal crops, world population 1/2nd main edible rice, and rice is the fruit of gramineous herbaceous plant's cultivation, comprises grain husk and caryopsis.Paddy is sloughed grain husk and is brown rice, and it is rice that the brown rice stone roller removes the chaff skin.Brown rice is made up of cortex, endosperm and embryo.Cortex is pericarp, the general designation of planting skin, perisperm, and during husk rice, most of cortex is ground by rice mill and removes into rice bran.So cortex also is called the chaff layer.Endosperm is the topmost part of rice.Endosperm can be divided into aleurone, inferior aleurone and starch cell.At grain of rice different parts, the gluten cell number is slightly different.Have only a confluent monolayer cells in its side, the outside of belly then has the 1-3 confluent monolayer cells, and then there is the 5-6 confluent monolayer cells at the back side.Inferior aleurone is in the below the aleurone layer, and its thickness has only several confluent monolayer cells, is easy to during pearling grind with aleurone.Aleurone is made up of the intimate square prothenchyma (of wood) of marshalling.Gluten cell is bigger, is full of tiny particulate matter in the cell, is called aleurone grain, and it is rich in protein, lipid, vitamin and organic phosphate.Research is learnt, 65% nutrient is accumulated in meter embryo and the cortex in the rice, and the biological activity that has in the rice almost all accumulates in meter embryo and the cortex, therefore, unpolished-rice nutrient is worth high, but its palatability is poor, people do not like to eat, and it is good that the white rice after smart the stone roller is eaten mouth, but the nutriture value value difference.Remove small part kind skin and only grind, keep the 80% high Nutritive Rice with epithelial layer, be difficult for again preserving, its active component can only survive about a week, be difficult to fresh-keeping storage, and this also is that palatability is better, the main cause that nutritious high Nutritive Rice still can not be promoted so far.

Summary of the invention

Purpose of the present invention will provide a kind of exactly and be convenient to fresh-keepingly, nutritious, is easy to promote edible grain variety.The high Nutritive Rice of band fresh-keeping packaging of the present invention also can be referred to as " unpolished rice ", and " unpolished rice " and its outer containter are formed.This high Nutritive Rice is through the light levigate stone roller of multimachine, the polishing of dry method wind-force, sloughs the rice of rice husk, reservation 80-95% cortex.Container is airproof antistaling container.The high nutrition " unpolished rice " that processes is packed in the antistaling container, charge into the O of weight ratio 1-3: 6-8: 22-26 ₂, CO ₂And N ₂, seal then.Can make unlikely the coming off such as kind skin on the grain of rice like this, can keep the life of bioactive ingredients and rice again, keep its nutritional labeling and freshness, fresh keeping time was more than ten months, people can be consumed throughout the year, the rice that mouthfeel is good, nutritious satisfy the demand of people to high-quality food, and cost is low, easy to implement to promote.

The specific embodiment

Adopt the light levigate stone roller of multimachine earlier, dry method wind-force polishing method processing rice, general four machines or four machines of adopting are with feeding-in and-out, control the granularity of each machine roller pressure, rotating speed and sand roller sand: the broken brown rice sand roller pressure of a machine is (30-60) g/ square centimeter, rotating speed (1400-1450) r/ minute, fine sand granularity (36-42) number, broken skin husk rice 20 percent; Two machines grind rough pressure (70-90) g/ square centimeter, rotating speed (1300-1350) r/ minute, ultra-fine fineness of sand (40-60) number, peeling is ground and is subtracted 40 percent, it is iron roll that three machines are wiped rough, pressure (300-450) g/ square centimeter, rotating speed (700-750) r/ minute, the peeling stone roller subtracts 30, four percent machine rice and is finished to iron roll, every square centimeter of pressure (250-300) g/, rotating speed (750-850) r/ minute, peeling is ground and is subtracted 10, makes the aleurone rate of retaining of rice be not less than 80 percent, and coverage rate absolutely.The bioactive ingredients and the life that keep rice to greatest extent.This high Nutritive Rice can be referred to as " unpolished rice ".At once high nutrition " unpolished rice " is packed into then in the airproof as shown in Figure 1 packing container 1, container 1 can be bag, tank or bottle, charges into the O of 1-3: 6-8: 22-26 then ₂, CO ₂And N ₂, add a cover 2 sealings at last.The high nutrition " unpolished rice " of this band antistaling container is convenient to store, transports and is sold, and storage life was more than ten months.As adopt inner wrapping, it is more rationally convenient that cook with the rice divided meal every day.

Claims

1, high nutrient fresh-preservation rice, form by rice and outer containter, it is characterized in that said rice is through the light levigate stone roller of multimachine, the polishing of dry method wind-force, slough rice husk, keep the high Nutritive Rice " unpolished rice " of 80-95% cortex, said container (1) is airproof container, pack into after the high nutrition " unpolished rice ", charge into the O of weight ratio 1-3: 6-8: 22-26 in the container ₂, CO ₂And N ₂, add a cover (2) sealing.
