Abstract
The invention provides an edible honey-dew melon film. The edible honey-dew melon film consists of the following components in parts by weight: 0.5-1 part of glucomannan, 5-10 parts of clear juice of honey-dew melon, 6-10 parts of sorbitol, 5-7 parts of gelatin, 0.08-0.1 part of protamine and 80-90 parts of water. The invention also provides a preparation method of the edible honey-dew melon film, and the prepared edible honey-dew melon film can be used for packaging the ready-to-eat foods, such as preserved fruit, soluble foods and candies. The edible packaging film provided by the invention has the flavor of the honey-dew melon and the faint grass-green appearance, and can be used for increasing the edible convenience of the packaged foods and also increasing the edible fun.
Description
Technical field
The invention belongs to food processing field, relate to packing film, relate in particular to a kind of hami melon 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 hami melon edible film, can be used for the packing of ready-to-eat foods, as preserved fruit, brew food, candy etc., 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 hami melon edible film is also provided simultaneously.
A hami melon edible film, its weight part is composed as follows: konjac glucomanna 0.5~1, the clear juice 5~10 of hami melon, Sorbitol Powder 6~10, gelatin 5~7, protamine 0.08~0.1, water 80~90.
A kind of preparation method of hami melon 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 clear juice of Sorbitol Powder, gelatin, hami melon that adds successively 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 hami melon 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.
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, the effect that it has natural anticorrosion, has guaranteed that edible film is in use difficult for microbial contamination, also can effectively prevent the corruption, rotten of packaged food simultaneously, extends effective period of food quality; (3) this edible packing membrane has the outward appearance of local flavor and the pistachio of hami melon, can increase the edible temperament and interest of packaged food.
