Freshness preservation and storage method of organic rice

Abstract

The invention discloses a freshness preservation and storage method of organic rice. According to the freshness preservation and storage method of the organic rice, a lactic acid bacterium fermentation product containing natural antioxidants is taken as a freshness preservation agent, wherein the lactic acid bacterium fermentation product contains multiple active antioxidant ingredients which arecapable of effectively inhibiting oxidative deterioration of the rice, as well as inhibiting growth of mildews, so that the lactic acid bacterium fermentation product is a safe and beneficial freshness preservation agent; moreover, pretreatments are performed on the rice by using supercritical fluid so as to improve adsorption capacity of the freshness preservation agent on surface of the rice sothat the treated rice has increased surface adsorption, and thus, adsorption between the rice and the freshness preservation agent is increased so as to realize effective adsorption of the freshness preservation agent; and finally, modified atmosphere packaging treatment is performed on the organic rice coated with the freshness preservation agent so that the treated organic rice has much longer shelf life and quality retention period compared with products of the same kind, and thus, the organic rice is very competitive in the market.

Description

technical field [0001] The invention relates to the technical field of grain processing, in particular to a fresh-keeping storage method for organic rice. Background technique [0002] With the improvement of residents' living standards, organic food is more and more popular among consumers. Organic rice, as a category of organic food, has begun to develop vigorously in our country. The so-called organic rice refers to rice that follows the production standards of organic agriculture, does not use genetically engineered organisms and their products in production, does not use chemically synthesized pesticides, fertilizers, growth regulators and other substances, and follows natural laws and ecological principles. Products obtained using a range of sustainable agricultural production methods. Although my country's organic rice cultivation started relatively late, it has developed very rapidly and there is huge room for consumption upgrades. [0003] Organic rice is not prot...

Problems solved by technology

In recent years, fresh-keeping technologies such as irradiation technology, nanotechnology, microwave technology, and smearing have been developed. Most of these technologies have problems of fresh-keeping, poor insect-proof effect, and the safety of additives needs to be considered, or they are expensive and complicated to operate and are not suitable for large-scale use.
