Plant antibacterial component based slow-releasing antibacterial fresh-keeping carton and production method thereof

Abstract

The invention discloses a plant antibacterial component based slow-releasing antibacterial fresh-keeping carton and a production method thereof and relates to the field of fresh keeping of agricultural products. The slow-releasing antibacterial fresh-keeping carton comprises a corrugated board and an antibacterial coating which coats the corrugated board, and the antibacterial coating is prepared from, by weight, 0.2-3% of clove extract, 0.4-4% of thymus serpyllum extract, 0.3-3% of lemon grass extract, 0.3-2% of prickly ash extract, 6-16% of moisture sensitive resin, 2-6% of beta-cyclodextrin, 0.02-2% of emulgator and 80-90% of distilled water. The production method includes: firstly, proportionally mixing all the components of the antibacterial coating with heating and stirring to produce a slow-releasing antibacterial coating solution; secondly, coating the corrugated board with the slow-releasing antibacterial coating solution to obtain the slow-releasing antibacterial corrugated board; finally, subjecting the antibacterial corrugated board to die cutting and creasing to produce the slow-releasing antibacterial fresh-keeping carton. The slow-releasing antibacterial fresh-keeping carton is applicable to fresh keeping of the agricultural products such as fruits and vegetables, and storage period of the fruits and vegetables can be prolonged by three to eight times.

Description

technical field [0001] The invention relates to an antibacterial fresh-keeping carton and a preparation method thereof, in particular to a slow-release antibacterial fresh-keeping carton based on plant antibacterial components and a preparation method thereof, which is suitable for fresh-keeping packaging of agricultural products such as fruits and vegetables under normal temperature conditions. Background technique [0002] Due to improper packaging and preservation, about 25% to 30% of fruits and 15% to 20% of vegetables are rotted and lost in my country every year, and the direct economic losses caused by this are as high as 100 billion yuan. In developed countries, the loss rate of fruits and vegetables is generally controlled below 5%. In order to suppress the rot of agricultural products such as fruits and vegetables, people use various methods such as low-temperature storage, controlled atmosphere preservation, heat treatment, irradiation treatment, and chemical prese...

Problems solved by technology

However, most of the research is still in the experimental stage, and there are still some problems: most of the natural plant antibacterial ingredients are easy to volatilize or oxidize and decompose and become ineffective; the antibacterial validity period of natural plant antibacterial ingredients cannot be controlled; Fresh-keeping packaging materials still lack mature technology
