Defrosting, deodorizing, bacteria-resisting, and fresh-keeping material and preparation technology thereof

Abstract

The invention provides a defrosting, deodorizing, bacteria-resisting, and fresh-keeping material and preparation technology thereof, and relates to the technical field of air purification, bacteria resistance, and fresh maintenance of a refrigerator. A material with long-lasting humidity-controlling, defrosting, deodorizing, bacteria-resisting, and fresh-keeping effects is arranged on the inner walls of a refrigerator and a freezer. The material prepared in the invention plays defrosting, deodorizing, bacteria-resisting, and fresh-keeping effects on inner space of the refrigerator and the freezer, decomposes and removes strange and odor gases, such as hydrogen sulfide, methyl mercaptan, ethyl mercaptan, trimethylamine, and ethylene, in the air or in the refrigerator or the freezer, and inhibits metabolism of fruits and vegetables, thereby reducing the activity of several main enzymes in the fruits and vegetables, and preventing ripening and deterioration of the fruits and vegetables. The conservation time of the fruits and vegetables is prolonged; the purpose of fresh-keeping is achieved; and freshness and taste of the fruits and vegetables are improved.

Description

technical field [0001] The invention relates to the technical field of refrigerator air purification, antibacterial and fresh keeping, in particular to a defrosting, deodorizing, antibacterial and fresh keeping material and a preparation process thereof. Background technique [0002] At present, the food in the refrigerator will produce peculiar smell and quality changes during storage. There are both internal and external reasons for this. The internal reasons mainly include chemical composition, tissue structure, biological characteristics, etc. The main reason is the environmental factors of storage: such as humidity, temperature, gas, microorganisms, etc. Different foods will emit different odors, and different foods will emit different odors when they are spoiled. [0003] The odors in refrigerators and cold storages mainly include the following types: the smell of hydrogen sulfide (H2S) emitted by rotten eggs and milk, the odor of ammonia (NH3) emitted by rotten meat, ...

AI Technical Summary

Problems solved by technology

[0004] The reason why fruit and vegetable food rots and deteriorates is mainly because of their respiration, ethylene gas and water evaporation loss, and the proliferation of microorganisms. Generally, the respiration of fresh fruit and vegetable food is carried out all the time, even after picking. Continuing, because respiration needs to consume nutrients in the body, which affects the quality and freshness, in order to limit its respiration, the current method is to store fruits and vegetables at low temperature and low oxygen as much as possible, because microorganisms can be effectively inhibited at low temperature and prevent the loss of water in fruits and vegetables, but under this condition, the fruits and vegetables did not stop breathing completely, but the breathing speed slowed down, so ethylene gas is still produced. The test proves that it is one part in a billion Low concentration of ethylene gas is enough to induce the ripening of fruits and vegetables. Once the fruits and vegetables are ripe, the quality will gradually decline, resulting in overripe, aging, softening and spoilage.

In addition, the design temperature of the refrigerating room in the refrigerator is usually around 1°C-10°C. Under this temperature condition, the water in the fruits and vegetables in the refrigerating room will evaporate to varying degrees, resulting in dehydration, discoloration, and dryness of the fruits and vegetables. Affect the freshness and taste of food, and the moisture will form frost and solidify on the back wall of the inner container of the refrigerator. These frosts will affect the cooling effect and energy saving. Condensation into water due to temperature rise, which flows away through the water outlet on the inner wall
