Room-temperature food preservation sheet and preparing method thereof

Abstract

The invention discloses a room-temperature food preservation sheet.The preservation sheet is formed by an adsorption carrier with an anti-bacterial extraction solution adsorbed.Water absorbent paper or non-woven fabric or a thin wood sheet meeting the food safety standard serves as the adsorption carrier.The anti-bacterial extraction solution is formed by mixing a camellia seed meal extraction solution and a plant mixture extraction solution, wherein the plant mixture is prepared from orange peel, tea leaves, pomegranate peel, flowers of chrysanthemum morifolium ramat, honeysuckle flowers and mint.The preservation sheet can be placed on a room-temperature and heated box lunch, pastries and other foods, and common bacteria such as escherichia coli, staphylococcus aureus and bacillus subtilis can be inhibited within a certain time at the room temperature.By means of the antibacterial effect of natural extract, the product can perform the preservation effect on foods at the room temperature or under heat preservation even the foods are not put into a refrigerator, and the method is convenient to implement, simple and capable of preventing peculiar smells and guaranteeing good sanitation.

Description

technical field [0001] The invention relates to a fresh-keeping sheet used for food fresh-keeping at normal temperature and a preparation method thereof. Background technique [0002] At present, people’s food preservation methods mostly use cold source low-temperature storage. This method requires certain economic conditions and high energy consumption. In addition, there is a method of using preservatives to preserve freshness, but most preservatives contain chemicals, which is not conducive to people. health. Some foods such as rice, vegetables, meat, seafood, etc. should be kept at a warm state, such as 40-70°C, which has a better taste. But at this temperature, the bacteria existing in the food, even if the number is small, can easily use the nutrients in the food to multiply in the food at a temperature suitable for their reproduction, causing the food to become rancid and deteriorate, and even make people sick. Nowadays, people's work and study are busy, the pace of...
