Description
Technical field
The present invention relates to a kind of food wrapper and preparation method thereof, be specifically related to a kind of degradable food packaging paper and preparation method thereof.
Background technology
Development along with food service industry, the food wrapper kind is day by day various, relatively common are cake paper, candy wrapper, vermicelli carton, bread wrapper, the biscuit carton, ice cream outer packaging paper using, wherein waterproof and oilproof type food wrapper gains great popularity, yet the overwhelming majority is all take macromolecular compounds such as polystyrene, polyvinyl chloride, polypropylene as covering material, simultaneously these materials have the degraded of being difficult for, recovery difficult large, burn characteristics such as producing toxic gas and harm ecotope.In addition, in process of production, the chemical such as the permeability-reducing admixture that in paper pulp, adds, sizing agent, SYNTHETIC OPTICAL WHITNER, staining agent, stablizer, UV light absorber and plasticizer.Migration occurs part chemical objectionable constituent under hot and humid environment is polluted food.In a word, food wrapper is endangering to a certain extent the physically and mentally healthy of people and is bringing disadvantageous effect to ecotope.From 1 day September in 2009, food wrapper must have the QS authentication marks to come into the market.Latest survey shows that chemical residues seriously is the underproof major cause of wrapping paper, therefore, in order to improve to greatest extent the security of food wrapper, should need not or use food grade additives instead as much as possible aborning.WHO and Environmental Protection in China expert think, will initiate from now on that everybody uses nontoxic, harmless full paper-made environmental protection bag, and paper product are easy to corruption, both can the reclaiming paper or do vegetable fertilizer, simultaneously again can environmental contamination reduction, and purify air.
Application number is that 02115925.4 patent of invention " but a kind of solvable edible composite corn starch packing-film and preparation method thereof " has been announced take W-Gum and konjaku as main raw material and made respectively main glue and auxiliary glue, but under the effect of softening agent polyoxyethylene glycol, ethylene glycol or Sorbitol Powder through spraying, dryly obtain solvable edible composite corn starch packing-film.Add the chemical of limiting the quantity of and adding in the numerous food in making processes, easily cause objectionable constituent osmosis pollution food in the hot and humid situation, in addition, physical strength is little to be difficult to satisfy processing request.
The article of " Packaging Engineering " the 1st phase Bian Xue, Cao Longkui in 2009 " potato residue prepare edibility internal packing membrane technique research " research take potato residue as main raw material, carrageenin, sodium alginate be membrane-forming agent, glycerine is that softening agent prepares the edible packaging inner membrance, and the packing film indices measured, have the characteristics such as smooth surface, dissolution rate is fast, water-intake rate is low.Yet the packing film color and luster that potato makes jaundice is attractive in appearance not, and meeting water dissolution is the packing film major defect.
Application number is that 02115925.4 patent of invention " preparation method of water-soluble chitosan packing film " has been introduced a kind of packing film making method take chitosan as main raw material, added edibility composition (such as white sugar, starch) in the making processes, the water soluble component polyvinyl alcohol, it is neutral that whole system is, and final drying obtains food packaging film edible, soluble in water.Yet the polyvinyl alcohol that adds in the film is contaminated food products in that infiltration in the situation of water is arranged, and therefore, the security of this packing film is still waiting to improve, in addition, and merely by polysaccharide and the composite shortcoming that forms a little less than all there is physical strength in food packaging film of other compositions.
Summary of the invention
In view of the deficiencies in the prior art, the object of the present invention is to provide a kind of degradable food packaging paper and preparation method thereof.
To achieve these goals, technical scheme of the present invention is:
(1) preparation konjac sol: take by weighing respectively Rhizoma amorphophalli glucomannan, carrageenin, each 4-8g of soybean protein isolate, 8-10g, 8-10g and be dissolved in the 1L water, stirring and leaving standstill swelling 2-3h obtains konjac sol;
(2) preparation slurry: getting water ratio is the former wood pulp of food grade of 15%-20%, and be 1 by the weight ratio of former wood pulp and water: 8-10 carries out molten slurry, and uses the sodium hydroxide adjusting pH of 0.1mol/L to be 7.5-8.5, is mixed with the food grade wood pulp; Described former wood pulp refers to without bleaching, and broken degree is the 150-200 order, and the length of contained wood fibre is 2.5-3.0mm;
(3) filler: adding accounts for the glycerine of konjac sol weight 0.3%-0.5% as softening agent in the konjac sol of step (1), and doubly add the prepared food grade wood pulp of step (2) by the 2.5-3.5 of konjac sol weight, under 70-85 ℃ of water-bath, utilize stirrer 10～15r/s to stir 0.5-2.5h, viscosity with the modified starch solution of 5%-20% is regulated colloidal sol makes viscosity be not less than 600Pa
S, the pH that regulates colloidal sol with sodium hydroxide or the powdered sodium carbonate of 0.1mol/L is 8.0-9.5;
(4) degassed masking oven dry: utilize ultrasonic degas machine ultrasonic degas 10-15min under 200-400W, to be cooled during to 45-50 ℃, roll-forming makes film, film is positioned over to dry in the 60-70 ℃ of baking oven to water ratio be not higher than 8%;
(5) wax, dry: take out film after the oven dry after the room temperature cooling, the edible paraffin of melting is sprayed at the tow sides of film, hang airing namely gets degradable food packaging paper.
The present invention has the following advantages: the preparation method of a kind of degradable food packaging paper of the present invention, take Rhizoma amorphophalli glucomannan as main raw material, interpolation soybean protein isolate, carrageenin are auxiliary material, take glycerine as softening agent, add slurry without bleaching, the therefore carcinogens such as Han dioxin and Organohalogen compounds not, and this fibre stuff porous, wall thickness, but Effective Raise becomes ventilation property and the intensity of paper; Through colloidal sol, mixing, swelling, dry and smear the operations such as edible paraffin, make degradable food wrapper, have the characteristics such as safety non-toxic evil, environmental protection; Simultaneously, improved significantly physical strength; The various raw materials that add are food grade, even if there is the phenomenon of osmosis also can contaminated food products, can be used as the inner packaging paper of ice cream, cake, the food such as fried.
