Abstract
The present invention relates to a moisture-prevention and mildew-prevention agent which is suitable for the moisture prevention and mildew prevention of agricultural and sideline products of foods, foodstuff, dry seafood, tobacco, medicinal materials, etc., leather, clothing, precision apparatus, etc. The moisture-prevention and mildew-prevention agent comprises the components of anhydrous calcium chloride, a carrier and fumaric acid diester or nipagin ester, wherein the carrier comprises methylcellulose, hydroxymethyl cellulose and a sodium salt thereof, xanthan, anhydrous calcium sulphate and quicklime. The product of the present invention has the advantages of low manufacture cost, good performance of moisture prevention and mildew prevention, safety, sanitation and no toxin.
Description
The present invention relates to a kind of protection against the tide, mould inhibitor, be applicable to protection against the tide, the mildew-resistant of agricultural byproducts such as food, grain, dried seafood, tobacco, medicinal material and leather and fur, clothing, precision instrument etc.
Protection against the tide, fungus-proof measure commonly used at present have following several: pack behind (1) article dry sterilization.This method requires very high to wrapping material and technology of the package, be difficult to popularize, and packing is taken the back apart and made moist mouldy before article do not use easily.(2) in packaging vessel, place siccative, siccative commonly used such as silica gel, its water separation capability is poor, and water regain is few, can only play the effect of protection against the tide, mildew-resistant at short notice, moreover its cost is also high.(3) directly add antiseptic-germicide or employing external control type antiseptic-germicide.This method can not play moisture-proof role, and its anti-mold effect also reduces because of article are moist simultaneously.
Below in conjunction with embodiment the present invention is described in detail.
Moiety of the present invention is: Calcium Chloride Powder Anhydrous, carrier, dimethyl ester or nipagin esters, carrier are methylcellulose gum, Walocel MT 20.000PV and sodium salt thereof, xanthan gum and mix anhydrous calciumsulphate, unslaked lime.Above-mentioned each composition drying, pulverizing are mixed later, can be packaged into product multi-form, different size, wrapping material can be ordinary packing paper, plastic film, plastic cup, jar, waterproof cloth and the metal vessels etc. of band breather hole.
Embodiment: with Calcium Chloride Powder Anhydrous 400g, calcium sulfate 400g, sodium cellulose glycolate 100g, dimethyl ester 100g, dry, pulverizing mixes later packing.Every parcel 3g can absorb to place in the air of the above moisture content of 4g, relative humidity 80% and still had water-retaining capacity in 5 days, can make the article of having taken apart in the one liter of container that seals do not make moist in two months, four months not mouldy.
The invention is not restricted to an above-mentioned embodiment.
Advantage of the present invention is:
1. low cost of manufacture is convenient to popularize.Its manufacturing cost only is equivalent to 1/2nd of silica gel, 1/5th of the present external control type mould inhibitor that uses.
2. moistureproof, fungicidal properties is good.Its water-retaining capacity is more than three times of silica gel, and under the same conditions, the effectively moistureproof phase is more than three times of silica gel, still has the fungicidal properties of certain hour after losing humidity resistance.
3. the various compositions of this product all are the foodstuff additive that are allowed to use, and safety, health, nontoxic when being used for food, are not worried to be eaten by mistake.
Claims (1)
1. a protection against the tide, mould inhibitor is characterized in that the moiety of this product is: Calcium Chloride Powder Anhydrous 400g, calcium sulfate 400g, sodium cellulose glycolate 100g, dimethyl ester 100g.
