Abstract
The invention provides an edible onion film which comprises components in parts by weight as follows: 10-15 parts of onion juice, 6-8 parts of sorbitol, 5-7 parts of gelatin, 0.6-1 part of gulcomannan, 0.08-0.1 part of protamine and 75-85 parts of water. As the same time, the invention further provides a preparation method of the edible onion film. The prepared edible onion film can be used for packaging directly edible food and has onion flavor, the eating convenience of the packaged food is increased, and the eating interest is added.
Description
Technical field
The invention belongs to food processing field, relate to packing film, relate in particular to a kind of onion edible film.
Background technology
Edible packing membrane (EPF), is called for short edible film, is that a kind of to take edible natural material (as polysaccharide, protein etc.) be raw material, the film with porous network structure forming by differing molecular interphase interaction.Edible film have easy degraded, edible, easy to use, environment is not produced to the advantages such as pollution, be a kind of packaging material for food of great exploitation potential for its, have good development prospect.At present, edible film widespread use in food product pack, but the kind of edible film is too single, is all colourless, tasteless, transparent film conventionally, can not meet the needs of diversified food, differentiation package.
Summary of the invention
The invention provides a kind of onion edible film, can be used for the packing of ready-to-eat foods, when edible, no longer need to remove packing, can edible film is edible together with packaged food, increased edible convenience.
A kind of preparation method of onion edible film is also provided simultaneously.
An edible film, its weight part is composed as follows: Conditions of Onion Juice 10~15, Sorbitol Powder 6~8, gelatin 5~7, konjac glucomanna 0.6~1, protamine 0.08~0.1, water 75~85.
Described gelatin is through pulverizing, cross the jelly powder of 160 mesh sieves.
A kind of preparation method of onion edible film comprises the following steps:
(1) by weight that konjac glucomanna is soluble in water, at 15 ℃ ± 2 ℃ temperature, soak 12 hours;
(2), to the Conditions of Onion Juice, Sorbitol Powder, the gelatin that add weight ratio in konjac glucomanna solution, at 60 ℃ ± 2 ℃ temperature and under 600~800rpm speed, stir 20-30 minute, then be heated to 90 ℃ ± 2 ℃, insulation 6-8 minute;
(3) with 10% food phosphates sodium solution adjust pH to 8.0-8.5, add protamine, after stirring, standing 2-3 hour, is film-forming soln;
(4) film-forming soln is inclined to flat board above, by knifing, made its formation have certain thickness and uniform film, dry at 60 ℃ ± 2 ℃ temperature, demoulding obtains onion edible film.
Protamine is a kind of alkaline protein, it to Bacillus subtilus, bacillus megaterium, bacillus licheniformis, solidify genus bacillus, Lactobacillus plantarum, lactobacterium casei, streptococcus faecium etc. and all have stronger restraining effect, the antibacterial effect in neutral and alkaline medium is more remarkable.
The allicin that Conditions of Onion Juice contains also has strong disinfecting effect.
Principal feature of the present invention: the supplementary material that (1) prepares edible film is food raw material, has improved the edible safety of edible film; (2) added protamine and Conditions of Onion Juice, they all have the effect of natural anticorrosion, have guaranteed that edible film is in use difficult for microbial contamination, also can effectively prevent the corruption, rotten of packaged food simultaneously, extend effective period of food quality; (3) this edible packing membrane has the local flavor of onion, can increase the edible temperament and interest of packaged food.
