Abstract

The invention relates to a method for fresh-keeping grain, comprising following steps: putting rice, or peart barley, or corn, or green bean or small red bean in thin-walled plastic container, and charging carbon dioxide of 70% into container at the same time, then closing the container, or filling rice or peart barley, or corn, or green bean or small red bean and carbon dioxide in thin-walled plastic container from the bottom simultaneously. The invention is characterized by practical and stability, it can protect the grain germ and case and make the protein in grain be kept in thorough dormant condition, by doing reach purpose of frsh=-keeping.

Description

A kind of grain fresh keeping method

Technical field

The present invention relates to a kind of grain fresh keeping technology.

Background technology

Paddy is a kind of important crops, and according to statistics, the population in the whole world about 50% all is staple food with the rice, and 21% of world population fuel value of food is taken from paddy.In developing country, about 60% dietary protein origin is in cereal, and in the decades in future, cereal is still the major protein source of 2/3 population in the world.The quality of rice protein is the best in each albuminoid of generally acknowledging, the nutritive value of rice protein is higher than aleuronat, its first limiting amino acid lysine content is higher than that other are all kinds of, its amino acid ligand relatively is rationally, compares its biological value (BV) with other grain protein and protein effectiveness ratio (PER) is higher.The hypoallergenic of rice protein makes it to be suitable as very much the food of baby or special population.Be rich in tens of kinds more than needed by human composition and physiologically active ingredient in the rice, particularly brown rice, and abundant enzyme (being in resting state).The a tree name research report claims, 65% nutrient in the rice (nutriment and must composition) is accumulated in meter embryo and the cortex, the bioactive ingredients that has in the rice almost all accumulates in rice and the cortex, and the biotic component in known rice embryo and the cortex is up to tens of kinds more than.The fresh-keeping rice embryo and the cortex of rice of just making of rice can more be protected and be preserved, and activity of proteins is maintained more.Existing rice and the fresh-keeping general employing film plastic pocket of some coarse cereals, film is very thin, intensity is low, be easy to make meter embryo and cortex to come off, and the gas concentration lwevel that charges into during general controlled atmosphere is very low, only account for about 20% of gas weight, can not make protein be in deep sleep state, so fresh-keeping effect is unsatisfactory.

Summary of the invention

The present invention is a kind of grain fresh keeping method, is rice or the seed of Job's tears or corn or mung bean or red bean are placed the thin-walled plastic container, charges into the CO more than 70% simultaneously in plastic containers ₂, sealed plastic container mouth then.Also can be with rice or the seed of Job's tears or corn or mung bean or red bean and CO ₂Begin to charge into the thin-walled plastic container from container bottom simultaneously.After filling, sufficient CO ₂, the sealing filling exit was placed one day.CO in the thin-walled plastic container ₂Fully infiltrate in rice or the coarse cereals; make protein be in smother; dormancy fully, form negative pressure in the thin-walled plastic container this moment, and bottle shrinks; grain is compressed; like this, the plumule and the top layer of grain have perfect shelter, and can not come off; thereby reach the purpose of fresh-keeping grain, its freshness date was more than 1 year.When edible, as long as open thin-walled plastic container filling mouth, fresh air enters container, makes the CO in the grain ₂Discharge, the protein in the grain finishes dormancy, recovers active.The grain of Bao Cuning was both nutritious like this, had kept the distinctive fragrance of grain again, was proper fresh-keeping.The present invention's a kind of cost-effective grain fresh keeping method of can yet be regarded as.But it is still unsuccessful that this method is used to preserve grain such as millet.

The specific embodiment

Embodiment 1, and rice is filled the thin-walled plastic bottle of two kilograms of volumes, pours into high-purity CO then in bottle ₂, after ten minutes, get final product with thermoplastic film sealing bottleneck.

Embodiment 2, in the can seed of Job's tears in the thin-walled plastic bucket of 5 kilograms of volumes, gas tube is inserted to the thin-walled plastic jar at the bottom of, pour into high-purity CO ₂, carry on while irritating, until filling the seed of Job's tears, make a jar interior CO simultaneously ₂Be not less than 70% of gas gross, then the hermetically sealed can mouth.

Claims

1, a kind of grain fresh keeping method is characterized in that rice or the seed of Job's tears or corn or mung bean or red bean are placed the thin-walled plastic container, charges into the CO more than 70% simultaneously in plastic containers ₂, sealed plastic container mouth then.

2, grain fresh keeping method according to claim 1 is characterized in that rice or the seed of Job's tears or corn or mung bean or red bean and CO ₂Begin to charge into until being full of the thin-walled plastic container from container bottom simultaneously.
