Description

Freshness protection package for prolonging storage time of broccoli by utilizing insect antibacterial peptide
Technical Field
The invention relates to a freshness protection package for prolonging the storage time of broccoli by using insect antibacterial peptide, belonging to the technical field of agricultural science.
Background
Broccoli, also known as cauliflower (scientific name: Brassica oleracea l.var.borrytis L.), is a vegetable. Broccoli is an annual plant of the brassica genus of the brassicaceae family, which is a variety of cabbage. The antibacterial peptide (antimicrobial peptide) originally refers to a kind of basic polypeptide substance with antibacterial activity produced by induction in the body of insects, the molecular weight is about 2000-7000, and the substance is composed of 20-60 amino acid residues. Most of the active polypeptides have the characteristics of strong alkalinity, thermal stability, broad-spectrum antibiosis and the like. The antibacterial peptide has broad-spectrum antibacterial activity and strong killing effect on bacteria, and particularly the killing effect on some drug-resistant pathogenic bacteria draws more attention. However, in the actual large-scale production, broccoli is very easy to rot and deteriorate, especially fresh and tender broccoli is not easy to store, and how to prolong the storage time of the broccoli becomes a great problem to be solved urgently. Therefore, this patent is a utility model of vegetable freshness protection bag, and some prior art products are materials related to the film used for the bag wall, such as cn03113758.x and CN 202110384271.1; some improvements related to punching bag walls, such as cn200820227731.x and CN 200520135848.1; there are double or multi-layered bags such as CN94243082.4, CN200620094989.8 and CN 200520014855.6. The closest technical products to the present application are CN96217220.0 and CN 201210588963.9. All the issued patents are designed products for keeping vegetables fresh or storing vegetables well, but no related patent application is found if the issued patents can prevent the vegetables from being dehydrated, dried and yellow. Therefore, broccoli is placed in a container containing antibacterial peptide fine mist for 10-30 seconds and then is put into a freshness protection bag provided with a freshness protection strip bag, meanwhile, the freshness protection strip is placed in the freshness protection strip bag, the freshness protection strip is a round paper strip with the cross section diameter of 1-centimeter and the length of 8-40 centimeters, the freshness protection strip is forcibly squeezed after the paper strip absorbs the antibacterial peptide solution, when the freshness protection strip does not drip liquid any more, the freshness protection strip is loosened and is put in a freshness protection strip bag cavity, and because the freshness protection strip can still keep a certain humidity after being wrung, water vapor released in the broccoli preservation process can be adsorbed, bacteria carried in the water vapor can be killed, the water vapor can not be accumulated into water drops in the freshness protection bag cavity, and because the broccoli needs to be treated by the antibacterial peptide fine mist in advance before being bagged, therefore, the antibacterial peptide has no dead angle to protect the broccoli from being invaded by bacteria, viruses, protozoa, molds and the like, and finally the purpose of prolonging the preservation time is achieved.
Disclosure of Invention
In order to overcome the problem of how to prolong the storage time of broccoli, the invention provides a freshness protection package for prolonging the storage time of broccoli by using insect antimicrobial peptide, the freshness protection package for prolonging the storage time of broccoli by using the insect antimicrobial peptide is characterized in that broccoli is placed in a container containing antimicrobial peptide mist for 10-30 seconds, then the freshness protection package with a freshness protection strip package is placed in the freshness protection strip package, a freshness protection strip is placed in the freshness protection strip package, the freshness protection strip is a round paper strip which is soaked in antimicrobial peptide solution prepared by adding 1 part of antimicrobial peptide into 50-500 times of water and has the cross section diameter of 1-centimeter and the length of 8-40 centimeters, the freshness protection strip is forcibly wrung after absorbing the antimicrobial peptide solution, when the freshness protection strip does not drip any more, the freshness protection strip is loosened and placed in a freshness protection strip bag cavity, and the freshness protection strip can still keep certain humidity after being wrung, and at the same time, the water vapor released in the preservation process of broccoli can be adsorbed, fungi carried in the water vapor can be killed, the water vapor is prevented from accumulating into water drops in the cavity of the preservation bag, and the broccoli needs to be treated by the antibacterial peptide mist in advance before being bagged, so that the broccoli can be protected from being invaded by bacteria, viruses, protozoa, molds and the like without dead angles by the antibacterial peptide, and the purpose of prolonging the preservation time is finally achieved.
