Abstract
The invention provides a microwave-specific food package bag and a manufacturing method thereof. The manufacturing method comprises the steps that air holes are formed in a plastic package body, film brei is brushed on the air holes, and the food package bag is obtained when the film brie is dried; the manufacturing method of the film brei comprise the steps that the corn starch and the crosslinked starches are mixed according to the proportion of 4:1, and starch slurry with 25% concentration is prepared when the mixed starches dissolve in water; the PH value is adjusted; the calcium chloride solution with 3.6% concentration is added into the starch slurry, and the starch slurry is stirred and heated to 70 DEG C; the starch slurry is cooled to 45 DEG C rapidly when the starch slurry is pasted fully, and the isoamylase is added into the pasted starch slurry according to the proportion that adding 50 ug isoamylase to per g of gram of starch; stirring is conducted for 3 hours, the isoamylase with equal amount is added further, stirring is conducted for 6 hours, and power brei is prepared after filtrating through a gauze. According to the microwave-specific food package bag and the manufacturing method thereof, starch film can melt gradually under a high-temperature and high-humidity environment, so that the food package bag can ventilate automatically.
Description
Technical field
The present invention relates to a kind of food pack, more particularly to a kind of food pack that can be used for microwave heating.
Background technology
Current food pack material includes papery, plastics etc., and in order to keep food hygiene, food pack is all close
Envelope, so just can guarantee that food is not contaminated in transport and sales process, but most food carry out microwave heating when
Wait, packaging bag can not again sealed, because food adds thermogenetic vapor to be full of in a large number inside packaging bag, need to open
, still there is contaminated possibility in packaging bag, so although feasible while when extensive supplying food, it is impossible to one
It is individual to go to tear packaging bag, it is time-consuming and laborious.Therefore need to develop it is a kind of can keep sealing again can direct microwave heating food
Product packaging bag.
The content of the invention
For defect present in background technology, it is an object of the invention to provide a kind of special food pack of microwave,
The food pack keeps the sealing of packaging bag in transport storing process usually, has certainly when microwave heating is carried out
Dynamic airing function, i.e., complete microwave heating by need not opening closed food pack.
In order to achieve the above object, the technical solution adopted for the present invention to solve the technical problems is：
A kind of manufacture method of microwave special food packaging bag, comprises the steps：
1) plastic packaging bag body is made；
2) multiple air-vents are opened up on the surface of plastic packaging bag body, the diameter of air-vent is maintained at 0.3-0.5mm；
3) in the corresponding position brushing film slurry of the multiple air-vents of inner surface of packaging bag body, film slurry completely covers air-vent
Lid；
4) during the packaging bag of swiped through film slurry will be applied as vacuum drying oven, with 50 DEG C of dryings 40 minutes, then with 65 DEG C of dryings
20 minutes, after the film molding on air-vent, packaging bag is taken out, that is, obtain microwave special food packaging bag；
Wherein described film slurry is adopted and made with the following method：
1) by corn starch and crosslinked starch according to 4:1 ratio mixing, is dissolved in after water and is adjusted to the shallow lake of concentration 25%
Slurry；
2) it is 5.0-6.0 25% starch slurry to be adjusted into pH value；
3) addition accounts for the calcium chloride solution of starch slurry weight 1.5% in starch slurry, and the concentration of calcium chloride solution is
3.6%, it is heated with stirring to 70 DEG C；
4) completely 45 DEG C are rapidly cooled to after gelatinizing, according to 50u isoamylases/g starch isoamylase, constant temperature stirring is added
After 3 hours, then the isoamylase of same amount is attached, be stirred for terminating after 6h, with obtaining slurry after filtered through gauze.
For the stable performance for keeping film to starch, the temperature control of film slurry is at 45-50 DEG C when brushing film is starched.
The reaction control of crosslinked starch affects have higher stability to heat, acid and shearing force, it has been found that using crosslinking
, using the film of corn starch processing, intensity improves more than 20% to the film that starch is processed after mixing with corn starch with individually.
Starch film easily becomes fragile if freeze-day with constant temperature, and the present invention adopts stage drying：50 DEG C of dryings 40 minutes, 65
DEG C drying 20 minutes, it is to avoid because intensity that freeze-day with constant temperature is caused declines.
It is a further object to provide a kind of microwave special packing bag, it adopts above-mentioned manufacture method to be obtained.
Of the invention main the characteristics of：
1st, the film being manufactured into by unique method and technique is starched, and to be brushed and form starch film after being dried, and the starch film has strong
Degree is high, toughness is big, the advantages of airtight, brushes after the inner surface of air-vent, can keep closed inside food pack
Property, make food in packaging bag be in air-tight state so as to ensure the safety that food is stored.Meanwhile, starch film has enough strong
Degree, can be maintained in daily storage transportation and not crush and burst apart.
2nd, the starch film that the film slurry is obtained after being dried, can automatic dissolving after temperature is more than 80 DEG C and moisturt register is more than 55%
Solve as slurry, due to the property, by the packaging bag as microwave-oven-heating after, after temperature is increased to 80 DEG C, due to food
Moisture come out with vapor form, starch film can gradually melt under high temperature and high humidity environment, and at this time, starch film is not
Air-vent is carried out again closed, the vapor come out by food in packaging bag is able to be come out from packaging bag, it is ensured that
The safety of microwave heating, it is to avoid the generation of " blast ".
3rd, the component overall safety of starch film, even if the slurry contamination after its thawing is to food, its main component is starch,
No any impact safe to food.
Specific embodiment
With reference to embodiment, the present invention will be further described：
