Abstract
The invention discloses a method for preparing grease resistant food wrapping paper. The method comprises the following steps of: preparing a grease resistant coating, performing vacuum degassing, coating grease resistant coating according to a ratio of 2 to 10 g/m<2> and drying at the temperature of between 60 and 110 DEG C. In a crude product of the grease resistant coating, the weight content of chitosan is controlled to be between 0.5 and 10 percent; and in the crude product of the prepared grease resistant coating, the weight content of chitosan is between 0.5 and 10 percent, the volume content of acetic acid is between 0.5 and 10 percent, and the weight content of sodium alginate is between 0.1 and 10 percent. In the grease resistant food wrapping paper obtained by the method, a grease resistant value is between 8 and 11, and the grease resistant food wrapping paper has the advantages of low cost, environment friendliness, high oil resistance and water resistance, no toxicity and the like.
Description
Technical field
The invention discloses a kind of preparation method of anti-fatty foods wrapping paper, belong to coating wrapping paper preparing technical field.
Background technology
In the packaging for foodstuff field, particularly for the packing of some oiliness article, most of manufacturers tend to adopt plastics as raw material.But owing in the processing procedure of rubbish, be difficult to after the plastics in landfills decompose, and discharge toxic gas after burning.The exploitation degradation plastic just becomes the emphasis of current tackling of key scientific and technical problems.But because material and technical problem, current degradation plastic still can't be degraded fully, and cost is higher, thereby drops into large-scale production and use as yet.
There is the degradable food package film that utilizes natural biologic material such as soybean protein to make to be used for the oily food packing at present; But edible packaging is extensive not enough for commercial applications; Can't replace the synthetic high polymer plastic sheeting, its reason mainly is the bad mechanical property of film, the natural possess hydrophilic property of edible polymer material own; It hinders moist limited, and problems such as its packing heat sealability and impressionability are still waiting to solve simultaneously.
The grease proofing food wrapper that Chinese patent 201495453U announces comprises facial tissue layer, ground paper layer, 3 layers of core paper layer, and between the sandwich layer at a distance from being pressed with membrane waterproofing and anti-oil lamella, facial tissue layer and ground paper layer all are coated with the sizing agent layer.Publication number is that the patent of CN201201764X provides a kind of used for packing foods grease proofing paperboard.This grease proofing paperboard is made up of face coating layer, lining, sandwich layer, bottom and anti-oil reservoir, and anti-oil reservoir is fluorine-containing oil-proofing agent.Greaseproof paper in the above patent fails to provide the oil preventing performance of the wrapping paper of individual layer paper substrate, and cost high, produce complicated.
The fluorocarbon coating can improve grease resistance, be used to produce anti-oily wrapping paper, but the fluorocarbon price is too high, harmful and can change the food local flavor, should not be used for packaging material for food.
Shitosan and paper all are ep-type materials, can degrade fully, fundamentally solve problem of environmental pollution.Shitosan shows chelating ability to the calcium in the food, can not reduce nutritive value of food, and shitosan also has antibiotic property and grease resistance.Sodium alginate belongs to natural macromolecular material, and have that biodegradability, avirulence, source are wide, film forming, grease resistance and low-cost advantage.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the prior art, provide that a kind of cost is low, environmental protection, anti-oily water repelling property are good, nonhazardous and reach the preparation method of the anti-fatty foods wrapping paper that does not influence flavour of food products.
According to technical scheme provided by the invention, the preparation method of said anti-fatty foods wrapping paper comprises the steps:
The preparation of anti-grease paint: shitosan, acetate and sodium alginate are dissolved in the deionized water and stir; Be made into anti-grease paint bullion; In anti-grease paint coarse fodder; The weight percentage of shitosan is controlled at 0.5%～10%, and the volumn concentration of acetate is controlled at 0.5%～10%; The weight percentage of sodium alginate is controlled at 0.1%～10%;
Vacuum outgas: the anti-grease paint coarse fodder that will be made into obtains processing anti-grease paint finished product through vacuum outgas; The vacuum of vacuum outgas is 0.02-0.05MPa;
Coating: select 60～90g/m
2The packing body paper, with anti-grease paint finished product the packing body paper one side be coated with, the coating weight of anti-grease paint finished product is 2～10g/m
2, obtain anti-fatty foods wrapping paper wet feed;
Oven dry: will resist fatty foods wrapping paper wet feed to put into temperature is that 60～110 ℃ baking oven toasted 2～5 minutes, obtains anti-fatty foods wrapping paper siccative.
The anti-fatty foods wrapping paper that the inventive method obtains, its kit rating is 6～11, advantages such as the anti-fatty foods wrapping paper that the inventive method obtains has that cost is low, environmental protection, anti-oily water repelling property are good, nonhazardous.
