Abstract
The invention relates to an antibacterial fresh-keeping film. The antibacterial fresh-keeping film is mainly used for fresh-keeping packaging of fruits, vegetables, meats, soybean products, marine products and grain non-staple food, and further can be used for covering food utensils and protecting the food utensils from bacterial pollution. The antibacterial fresh-keeping film has characteristics of being wide in antibacterial spectrum, long in fresh-keeping time, strong in temperature tolerance, non-toxic and harmless, good in biological degradability, corrosion-resistant and deodorant, safe and free from abnormal odor, and stable in chemical properties, and is not only suitable for freezing preservation, but also suitable for microwave heating, therefore, the antibacterial fresh-keeping film is a novel food packaging product with ecological healthcare performance.
Description
technical fieldthe present invention relates to a kind of antimicrobial preservative film, the effective constituent of formula is chitosan, titanium dioxide, Xylo-Mucine, medical stone, polyethylene and glycerol, through special production technique, is prepared from.The Freshkeeping Packaging that is mainly used in fruit, vegetables, meat, bean product, sea-food, cereal non-staple foodstuff, also can cover food utensil, makes it avoid bacterial contamination.Preservative film is the plastic packing product of a class fresh-keeping foodstuff conventional in daily life, has appropriate oxygen-permeable and Water Vapour Permeability, can regulate by fresh-keeping product oxygen content and moisture content around, intercepts koniology, thus the freshness date of food and extend.If add anti-microbial property in fresh-keeping field, will make packaging material for food produce qualitative leap, become novel health care wrapping material.
background technologyin material progress day by day flourishing today, huge numbers of families have been come in the use of preservative film, become the non-defective unit of herbal.Commercially available preservative film product is all to take ethene masterbatch as starting material, and according to the different sorts of ethene masterbatch, preservative film can be divided into three major types again, is respectively PE preservative film, PVC fresh-preserving film and PVDC preservative film.Wherein, this bi-material of PE and PVDC is safe to human body, can relievedly use, and PVC is very large to the harm of human body, and the softening agent preheating in it is met oil and can dissolving be moved out, with food, enters human body, and human body is caused to carcinogenesis.Therefore, country prohibites and does not allow to fill hot food, prepared food and at microwave-oven-heating with PVC fresh-preserving film.Occurring in nature exists a large amount of microorganisms, and these hundreds of millions of tiny organisms are distributed in air, water, soil, ubiquitous.Food is usually corrupt mouldy in put procedure, and in this and air, the fungal spore of disperse everywhere has very large relation, especially in coastal humid area.Existing preservative film is seldom focused on antibacterial and mouldproof aspect, and this just provides opportunity and direction for we develop a kind of preservative film with anti-microbial property.Therefore, we wish to invent a kind of food fresh keeping membrane with antibacterial and mouldproof performance, and antibiotic health care material is well dissolved in preservative film, make it have fresh-keeping, high-efficiency antimicrobial lastingly, the high low temperature of tolerance, the feature that nontoxic, biological degradability is good.
summary of the inventionthe invention provides a kind of antimicrobial preservative film, main points are to select suitable component, and carry out rational mixture, through special production technique, are prepared from.The formula following (component and weight percent %) of antimicrobial preservative film: chitosan 1.5-3, titanium dioxide 0.5-1, Xylo-Mucine 0.8-1.5, medical stone 1-3, polyethylene 8-12, glycerol 1-2, deionized water adds to 100.
Chitosan is the deacetylation product of chitin; it is β-1; 4 glucosamine polymers; there is good biological film-forming properties and biocompatibility, biodegradable, can not cause environmental pollution; there is stronger bacteriostatic action; its principle may be that the negative charge on its positive charge and microorganism cells film surface produces association, has changed the permeability of microorganism cells film, thereby causes that microorganism cells is dead.
Titanium dioxide is photocatalyst-type anti-biotic semiconductor material, its energy band structure is discontinuous, there is a forbidden band filling up between the low energy valence band of electronics and empty high energy conduction band, when they are subject to frequency and are greater than the rayed of the frequency that forbidden band energy is corresponding, electronics in valence band is excited on conduction band, generates electronegative high reactivity electronics (e on conduction band
-), in valence band, generate positively charged hole (h
+), due to highly active electronics can with airborne oxygen and hydrogen reaction Hydrogen Peroxide, and the reaction of cavity energy and water in air generates hydroxide radical.The hydrogen peroxide generating can become organic substance decomposing carbonic acid gas and water with hydroxide radical, thereby kills the pathogenic micro-organisms such as bacterium.
Xylo-Mucine is to take a kind of high polymer fiber element ether that Mierocrystalline cellulose, caustic soda and Mono Chloro Acetic Acid make as main raw material, it is a kind of silver ions linear species, in food, as additive, use, integrate the several functions such as thickening, suspension, emulsification, stable, conformal, film forming, expanded, anti-corrosive fresh-keeping, acidproof and health care, be called as industrial monosodium glutamate.In this formula, as one-tenth membrane matrix, play a role.
Medical stone is a kind of to biological nontoxic, harmless and have certain bioactive composite minerals or medicinal rock, has the performances such as adsorptivity, solvability, PH modulability, biological activity and mineralising.Medical stone is leachable to trace element and the necessary amino acid of human body such as human body and useful major element K, Na, Ca, Mg, P and the Si of organism, Fe, Zn, Cu, Mo, Se, Mn, Sr, Ni, V, Co, Li, Cr, I, Ge, Ti in the aqueous solution.Can widespread use health care, the field such as food, beverage and purification of water quality, sewage disposal, anticorrosion, deodorization, fresh-keeping, decontamination, porcelain making and plant husbandry and aquaculture, in this formula, mainly play fresh-keeping, deodorization.
Polyethylene is called for short PE, is a kind of thermoplastic resin that ethene makes through polymerization.Nontoxic, odorless, feel, like cured, has good resistance to low temperature (minimum reaching-70～-100 ℃).Chemical stability is good, the corrosion of the most of soda acids of ability, and water-absorbent is little, and electrical insulation capability is good.Be mainly used to manufacture film, wrapping material, container, pipeline, daily necessities etc., in this formula, as one-tenth membrane matrix, use.
Glycerol, because its nonpoisonous and tasteless nuisanceless quilt is in a large number for foodstuffs industry, cosmetic industry, increases film-forming properties mainly as softening agent in this formula.
Preparation technology of the present invention is:
(1) by proportioning, described component Xylo-Mucine is put into deionized water, standing 12h makes its abundant swelling, and normal temperature is deposited standby;
(2) by proportioning, described component chitosan, titanium dioxide, medical stone are added in emulsion tank, stir, emulsification 20min;
