Problems solved by technology

[0003] At present, some rice preservation uses vacuum packaging to achieve the purpose of rice preservation, but the cost is high, the packaging quantity is small, and the public consumption capacity is limited, which does not meet the needs of ordinary consumers.
As a relatively satisfactory fresh-keeping technology based on deoxidizers, it has been rapidly developed and popularized in recent years, but the general cost is relatively high, and they have disturbing hidden dangers

Embodiment 1

[0017] Add 33g of citric acid, 78g of sodium dehydroacetate and 23g of calcium lactate one by one in 1000g of water, mix, and slowly add 45g of chitosan after all dissolve, and stir rapidly until all dissolve.

Embodiment 2

[0019] Add 31g of citric acid, 73g of sodium dehydroacetate and 24g of calcium lactate one by one in 1000g of water, mix, and slowly add 48g of chitosan after all dissolve, and stir rapidly until all dissolve.

Embodiment 3

[0021] Add 32g of citric acid, 76g of sodium dehydroacetate and 22g of calcium lactate one by one in 1000g of water, mix, and slowly add 43g of chitosan after all dissolve, and stir rapidly until all dissolve.

[0022] How to use: When polishing the rice, use a humidifier to evenly spray the preservative on the surface of the rice. The dosage is 2-2.5kg of preservative per ton of rice.

Abstract

The invention relates to a rice antistaling agent and a preparation method thereof. The rice antistaling agent is prepared by matching sodium dehydroacetate, citric acid, calcium lactate and chitosan according to the synergistic action of a bacteriostatic agent, an antioxidant and a film-forming agent through mixing and stirring. The rice antistaling agent has high dissolving efficiency, high safety and stable performance and not only can well prolong the shelf life of the rice but also has the calcium enriching effect. When in use, the antistaling agent is only evenly sprayed to the surface of the rice by using a humidification machine when the rice is polished. The rice antistaling agent is very convenient to use.

Description

technical field [0001] The invention relates to a rice fresh-keeping agent and a preparation method thereof, belonging to the field of grain fresh-keeping. Background technique [0002] Rice preservation has always been a major problem in food storage, especially in high-temperature and high-humidity seasons, it is easy to breed mold, mildew and quality deterioration, this is mainly because rice nutrients are exposed to high-temperature and high-humidity air for a long time Such pollution and self-contained lipase oxidation mildew and other reasons. [0003] At present, some of the fresh-keeping rice uses vacuum packaging to achieve the purpose of rice fresh-keeping, but the cost is high, the number of packages is small, and the consumption capacity of the public is limited, which does not meet the needs of ordinary consumers. Deoxidizer-based fresh-keeping technologies have been rapidly developed and popularized in recent years, but the cost is generally high, and they hav...
