Abstract
The invention provides technology for producing a vegetable protein and konjac glucomannan composite degradable and edible film, belonging to the technical field of food processing. The technology comprises the following main production processes: mixing and stirring soy protein, glycerin, konjac glucomannan and sodium carboxymethylcellulose; heating the materials to react; then carrying out tape casting on the film solution on a copper plate through homogenization and degasification; adopting a copper plate film forming conveyer belt to firstly pass through steam drying pipeline equipment and then pass through cooling pipeline equipment with relative humidity being about 50% to form a film; and finally adopting mechanical film rolling equipment to roll the film, thus producing a degradable and edible film with high strength. The film material has good mechanical performance and oil, moisture and oxygen resistance. The film can be applied to packaging of various materials such as food, health products, drugs, feed and the like.
Description
Technical field
A production technology for vegetable-protein konjak gum composite degradable edible film, belongs to food processing technology field.
Background technology
Degradable edible film be a kind of not only can coating-film fresh-keeping but also the new packaging material that the packaged form such as bag, box replaces the conventional synthesis wrapping material such as plastics can be processed into, simultaneously it can also be an integral part of food, and increases color, smell and taste and nutritive value for food.Degradable edible film has pollution-free, degradable advantage, be that plastic wrapping is unrivaled, this is on the rise at " white pollution ", and most developed country has forbidden or limited the use of plastic wrapping and advocate and select beyond doubt a kind of best selection today of " Green Packaging ".So the degradable edible film wrapping material technology of preparing integrating these advantages is just becoming one of important technology that food service industry generally has an optimistic view of, there is good development prospect.
In existing background technology, U.S. patent Nos 6162475 reports the making method of the edibility active packing utilizing PVA to be base-material, this packaging has good fresh-keeping effect to food, Robert R Holcomb reports the method and apparatus of charge distribution on the active film that changes and have the electric allomeric function stability of thin film physics, and this has vital role to the performance improving active film.China is in the intellecture property of edible film, mainly concentrate on the formula of film, ZL02139279.X reports a kind of edibility yam starch composite food package film and preparation method thereof, film forming is stirred mainly through starch pasting, ZL02151253.1 reports the preparation method of composite comestible shell polysaccharide membrane, it take Chitosan-phospholipid complex as the main raw of film forming, with membrane-forming agent or toughener, softening agent and linking agent for ancillary component, by temperature control film forming.These researchs all do not relate to the control method (stage by stage dry) of film forming properties, the mechanism (limit to) of pressure treatment, particularly film forming and technical study above.Report is had no to the inventions such as edible film component mechanical index intensity and research.
In sum, in the research of degradable edible film, mainly concentrate in film forming formulation and mechanism both at home and abroad, be conceived in the applied research of film.To the performance of film own as tensile strength, moisture-inhibiting, ventilation property, water-soluble research, processing mode and improve material aspect of performance research less, compared with other packing techniques modern, still there is imperfection part, as performance is not high, production technique imperfection, thus the range of application limiting degradable edible film.Excellent preservative film, especially degradable edible film, all should have high strength, good barrier and controlled atmosphere to a certain degree and certain biocidal property.
Summary of the invention
The present invention is to provide a kind of is main raw material with soybean protein, with the use of components such as glycerine, konjak gum and Xylo-Mucines, by the new technology of homogeneous, the obtained degradable edible film novel material such as degassed, dry.The present invention adopts the method for vacuum outgas, is conducive to except the bubble in striping liquid; The present invention adopts copper coin curtain coating, is conducive to taking off film, can prevent film from ftractureing.The present invention adopts soybean protein and glycerine, konjak gum and Xylo-Mucine to react, and can keep higher viscosity stability under low temperature, high-shear conditions, thus keeps its high strength ability.The glycerine that product of the present invention adds, konjak gum and Xylo-Mucine, effectively can improve the mechanical property of film, oil resistance performance, oxygen resistance and block-water performance, reaches the shelf-lives object extending packaged food.
Embodiment
Soybean protein is utilized to produce a technology for degradable edible film,
1, component allotment: 90kg soybean protein, adds 1000L distilled water, 0.20L glycerine, 1.2kg konjak gum and 2kg Xylo-Mucine under stirring, regulate film liquid acidity, after homogeneous, under 90 DEG C of water bath condition, heated and stirred, until complete reaction, obtains coating solution.
2, degassed: at 0.1MPa deaerated under vacuum (0.5h-2h).
3, curtain coating: require to arrange blade width and height according to film thickness, curtain coating is in can on the copper coin conveying belt of controlling diaphragm thickness.
4, dry: copper coin film forming conveying belt first by drying with steam pipe-line equipment, and then by relative humidity about 50% cooling duct equipment, film forming.
5, film is taken off: machinery volume film, packaging, storage.
Claims (2)
1. the production method of a vegetable-protein konjak gum composite degradable edible package material, it is characterized in that: 1) 90kg soybean protein, 1000L distilled water, 0.20L glycerine, 1.2kg konjak gum and 2kg Xylo-Mucine is added under stirring, regulate film liquid acidity, after homogeneous, under 90 DEG C of water bath condition, heated and stirred, until complete reaction, obtains coating solution; 2), after deaerated under vacuum, curtain coating is on the copper coin film forming conveying belt of the scraper with adjustable-height and width of controlled film thickness; 3) copper coin film forming conveying belt is first by drying with steam pipe-line equipment, and then by relative humidity 50% cooling duct equipment, film forming, finally roll up film device by machinery and roll up film, packaging forms.
2. the production method of a kind of vegetable-protein konjak gum composite degradable edible package material according to claim 1, is characterized in that, described degradable edible package material is used for the packaging of food, healthcare products, medicine or feed.
