Abstract
The invention discloses a kind of fruit preservative papers, belong to paper product field.The present invention is in 40 ~ 55 DEG C, take ethyl cellulose, inorganic powder, composite modified constituent of chitosan that 1 ~ 2h is mixed in reaction kettle, after be cooled to 20 ~ 25 DEG C plasticizer, spinach compound extracted solution, polylysines mixing be added, 40 ~ 60min is stirred with 300 ~ 350r/min, obtains antistaling coating; antistaling coating is taken to be sprayed on the side of individual wood pulp body paper; stands 5 ~ 10min, sprays antistaling coating again in wood pulp body paper homonymy, stand 5 ~ 10min; drying is to get fruit preservative paper.It is short that the present invention solves the current fruit preservative paper function time, the inapparent problem of preservation.
Description
Technical field
The invention belongs to paper product fields, and in particular to a kind of fruit preservative paper.
Background technology
In recent years, Chinese fruit industry development is very fast, however preserving fruit and vegetable utilizing storage capacity seriously falls behind, and the shelf-life is shorter,
It is difficult to ensure the freshness of fruit.Fruits and vegetables rot to be the basic reason for causing the preserving fruit and vegetable utilizing phase short, and fruits and vegetables storage condition is wet
Degree, temperature, cleannes and oxygen concentration are the principal element for causing fruits and vegetables rotten, the rotten speed and aforementioned four of fruits and vegetables
The value of factor is directly proportional, i.e., temperature is higher, and humidity is bigger, and cleannes are poorer, and oxygen concentration is bigger, the rotten speed of fruits and vegetables
Degree is faster.So-called cleannes refer mainly to the bacterial content in storage condition air（Mainly mould）, these bacterium parts
In natural air, a part is contained on the epidermis of fruits and vegetables, and humidity, temperature, oxygen are the hotbeds of bacterial reproduction.It changes
Yan Zhi, temperature is higher, humidity is bigger, oxygen is more sufficient, and the speed of bacterial reproduction is faster.It is well known that for most of food
For, the exceeded growth and breeding of microorganism is the main reason for leading to food spoilage.In the storage and transport of food, if warm
Degree, humidity and gas flow it is suitable, microorganism will raised growth breeding, accelerate food spoilage.Food packaging is as food and outside
Last one of barrier of boundary's environment has particularly important relationship to the holding of food quality.As people anticipate to environment protection health
The enhancing of knowledge, the requirement to packaging are also higher and higher.Tin foil has become the country as a kind of environmentally protective Perserving materials
The research emphasis of outer researcher.
Antistaling agent is mainly added in paper substrate or is coated on paper substrate surface for the preparation of tin foil, makes it have certain
