Description
Technical field
The present invention relates to macromolecule polysaccharide field of membrane material, particularly to a kind of preparation method of complex polysaccharide edible film.
Background technology
The real research of edible film starts from 20th century 50, the sixties, the substantial amounts of people from this countries in the world governmental input
Power and material resources research edible film, and obtain certain progress.Present edible film has been changed over by single component molding,
And develop into several functions property, the multi-component camposite membrane that multiple polysaccharide macro-moleculars are made.Edible film is new as one kind
Packaging material, have the advantages that environmental protection, quality that is biodegradable, nontoxic, can improving food, but also have battalion
Support and be worth.
According to edible film to prepare material different, can be divided into polysaccharide edible film, protein edible film, lipid edible film and
This several conventional edible film of compound edible film.The film that two or more polysaccharose substance is formed also widely is ground
Study carefully, conventional polysaccharide edible film has starch film, modified cellulose film, chitosan film and glucomanan film etc..Because polysaccharide is special
Different long-chain helical molecular structure, its stable chemical nature, it is adapted to long-time storage and various storage condition, but they all belong to
In hydrophilic polymer, hinder moist general very little, during polysaccharose substance forms film, intermolecular hydrogen bonding and intramolecular
Hydrogen bond plays important role.
Content of the invention
The present invention is directed to problem present in background technology, provides a kind of preparation method of complex polysaccharide edible film, its skill
Art scheme is as follows:
A kind of preparation method of complex polysaccharide edible film, comprises the steps:

To the konjaku glucomannan hydrosol for 0.5-3% for the mass percent, standby；
2) by after upper step products therefrom casting film-forming, it is dried, takes off film, obtain final product complex polysaccharide edible film.
As preference:
Also comprise the steps: between described step a and step b
A1, weigh plant polyose, add distilled water or organic solvent so as to dissolving or dispersed, in 30 DEG C of -90 DEG C of water
In bath, stirring 30-120 min obtains the polysaccharide dissolving phase that mass percent is 0.5-3%；
A2, by polysaccharide dissolving be added to step a be obtained the konjaku glucomannan hydrosol in, stirring so that it is sufficiently mixed
Uniformly.
Plasticizer is also included, the quality of plasticizer is konjaku glucomannan and plant in described distilled water or organic solvent
The 0-30% of polysaccharide quality sum.
In product in described step b, the mass percent of solute is 0.5-3%.
The operating procedure of the drying in step b is: again in 30 DEG C of -70 DEG C of dryings after 0-120 min being dried at 70 DEG C -90 DEG C
6-12h, is then placed in 20-30 DEG C again, balances 0-3h under the conditions of 30-80% rh.
Described plant polyose is konjaku glucomannan, ethyl cellulose, carboxymethylcellulose calcium, pulullan polysaccharide, can obtain so
Glue, the algin mixture of one or more therein.
Described plasticizer is water, glycerine, SA dibutyl ester therein one or more.
Organic solvent in described step 2 is ethyl acetate or absolute ethyl alcohol.
The complex polysaccharide edible film of present invention preparation includes konjaku glucomannan-ethyl cellulose composite membrane, Amorphophallus rivieri glucomannan
Glycan-carboxymethylcellulose calcium composite membrane, konjaku glucomannan-curdlan composite membrane, konjaku glucomannan-algin are combined
Film, konjaku glucomannan-pulullan polysaccharide composite membrane, konjaku glucomannan-curdlan composite membrane, konjaku glucomannan-second
Base cellulose-curdlan composite membrane etc..
The polysaccharide composite edible film flat smooth of this method preparation, the film thickness 0.02-0.1mm obtaining, light transmittance is well saturating
, in 60-90%, good mechanical properties tensile strength is in 30-150mpa for light rate.This preparation method is easy, solves some existing
Technical problem such as oil base phase is incompatible with aqueous phase, phenomenon of phase separation, and organic reagent consumption is few, low cost, degradable, solvent
Residual is low, meets the residue criterion of national edible packing film, the membrane safety prepared is edible, edible film packaged food shelf life exists
30-90d scope.
