Abstract
The invention relates to a method for preparing a freshness-retaining bag containing enteromorpha fiber. The method comprises the following steps: extracting the enteromorpha fiber; adding the enteromorpha fiber into paper pulp fiber according to the ratio of 4 to 5 percent to prepare the freshness-retaining bag containing the enteromorpha fiber; and coating 5 percent semi-deacetylation chitosan solution in the freshness-retaining bag. The freshness-retaining bag prepared by the method has bacteriostatic effect; the semi-deacetylation chitosan solution coated in the freshness-retaining bag can effectively inhibit water loss of vegetables and fruits; and the freshness-retaining bag has wide application prospect.
Description
Technical field
The present invention relates to a kind of food preserving bag preparation method, be specifically related to a kind of preparation method who contains waterside moss fiber freshness protection package.
Background technology
Present vegetables and Fruit fresh-preservation bag mostly are the PE freshness protection package, and in preservation process, inwall tends to long-pending full water pearl, along with the prolongation of time also can cause rotting of vegetables and fruit.And the paper bag freshness protection package easily causes the water loss of vegetables and fruit, shortens the shelf-life.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this invention is to provide a kind of preparation method who contains waterside moss fiber freshness protection package.
Technical scheme of the present invention is: a kind of preparation method who contains waterside moss fiber freshness protection package may further comprise the steps:
A, with after the dehydration of fresh Enteromorpha, be soaked in the sodium hydroxide solution of 2mol/L of 10 times of weight, soaks after 24 hours and filters, leach thing pressurization decatize, then take out, polish, pulp washing leaches, and namely obtains the waterside moss fiber;
B, the waterside moss fiber is joined in the paper pulp by 4～5% weight ratios, fully behind the mixing, can obtain containing the paper of waterside moss fiber through copying paper moulding, oven dry;
C, the paper that will contain the waterside moss fiber are made freshness protection package, smear 5% half chitosan solution in freshness protection package.
Described steam temperature is 120～150 ℃, and pressure is 0.1～0.2MPa, and decatize heat time heating time is 1～2 hour.
Freshness protection package of the present invention has bacteriostasis, and cost is low, and the Enteromorpha raw material sources are abundant; In the half chitosan solution that is coated with can the establishment vegetables and the water loss of fruit, have broad application prospects.
The specific embodiment
