Description
Technical Field
The invention relates to a fruit fresh-keeping tank with a bionic eggshell structure and a sterilizing cloth cover arranged in the bionic eggshell structure, and belongs to the technical field of zoology experiments.
Background
Eggshells are naturally formed by nature. The eggshell structure can be divided into five layers from inside to outside, and the first layer of eggshell inner membrane (called membrana Follicularis ovi from the second part of Chinese pharmacopoeia, which comprises complex proteins composed of fibrin, keratin and mucopolysaccharide, accounting for 15-17% of the total weight of eggshell);a second eggshell outer membrane; a third papillary cone layer; a fourth grating layer (sponge layer) and a fifth eggshell membrane. The eggshell is formed by eggshell-less egg-inner membrane (keratin membrane-protein fiber) -outer membrane (which is the foundation for eggshell formation) -nipple layer-sponge layer (determining eggshell thickness and hardness, caCO) 3 ) Shell membrane (useful for maintaining the strength and freshness of the protected eggshells). The eggshell structure of an egg is porous, and the eggshell is porous and breathable in general so as to facilitate metabolism during internal life evolution. The antibacterial peptide source refers to an alkaline polypeptide substance with antibacterial activity which is generated by induction in an insect body, and certain antibacterial peptides have powerful killing effect on partial fungi, protozoa, viruses, cancer cells and the like. Fruit refers to a plant fruit that is juicy and has a predominantly sweet and sour taste. The fruit not only contains rich nutrition, but also can promote digestion. The existing fruit preservation equipment and method are good and practical, such as fruit preservation bags, fruit preservation vehicles, fruit preservation warehouses and preservation methods: if not cooked, the fruits are not delicious and possibly harmful to health, and the fruits are stored in the refrigerator after being cooked at normal temperature. Hard skin fruits are often put directly into a refrigerator, such as: watermelon, pineapple, cantaloupe and other fruits. The fruits with thin and soft skin are put into a plastic bag and then put into a refrigerator. Such as apples, pears, mangoes, etc. More particularly, if the fruits such as litchi and longan are placed in a refrigerator for a long time, the shells are dried and hard to turn black, and the flavor of pulp is affected, so that people can keep the fresh taste of pulp by spraying a little water on the fruits before placing the fruits in plastic bags. The litchi can be cut off by scissors, soaked in salt water for several minutes, fished out, and then put into a plastic bag to be put into a refrigerator, so that the flavor can be kept for a long time. From the above, all the fruit fresh-keeping devices and methods are quite troublesome at present, so how to conveniently, quickly and efficiently keep fresh daily fruits is a serious problem to be solved urgently? Therefore, the porous structure of the bionic eggshell is designed into a fresh-keeping tank, and the bionic eggshell is arranged in the fresh-keeping tankThe fruit fresh-keeping tank with the sterilizing cloth cover is necessary to achieve the purposes of keeping fruits fresh and prolonging the storage time of the fruits by forming a micro-oxygen environment in the fresh-keeping tank artificially, and utilizing quicklime to remove the water possibly causing the decay of the fruits and utilizing the sterilizing cloth cover immersed with the antibacterial peptide in time when the fruit cells can breathe normally.
