Abstract
The present invention relates to a deoxidizing fresh-keeping agent, consisting of (wt%) 40-60% of iron powder with 80-200 meshes, 0.4-2.5% of salt, 0.2-3.5% of active carbon, 1-3% of quick lime with 12-14 meshes, 8-16% of water, 3-15% of dimethyl fumarate and 47.4-0% of coal cinder with 12-14 meshes. Said deoxidizing fresh-keeping agent has the double fresh-keeping function of deoxidizing and sterilizing, so that it can be extensively used for fresh-keeping for low-moisture materials, such as food, medicinal material and tea, etc..
Description
The present invention relates to a kind of antistaling agent that is used for food fresh keeping, particularly a kind of deoxidizing antistaling agent.
Along with improving constantly of living standard, people improve constantly the quality requirements of food etc., and the production of antistaling agent is also maked rapid progress.Adding from original mildew-resistant, anticorrisive agent develops into Deoxygen Packaging of today.Mildew-resistant, anticorrisive agent be to suppressing going mouldy and putrid and deteriorated certain effect being arranged of food, but human body is had certain infringement, so progressively eliminated; Deoxygen Packaging is to absorb oxygen in the packaging bag with deoxidier, suppresses microbial growth and breeding, reaches fresh-keeping purpose.As Chinese patent application number is that 88105412.7 " 504 double suction agent " just belongs to deoxidation type antistaling agent.But use this class antistaling agent if the packaging bag air permeability is big or because of sealing the seepage phenomenon is not arranged sternly, then deoxidier just can not play effect that deoxidation is fresh-keeping.Equally, if food itself just has anaerobic bacteria to exist, then this class deoxidier just can not reach fresh-keeping purpose.Also have and use dimethyl fumarate to make antistaling agent, it can form one deck gas phase protection layer, kill bacteria around packing material.But cross when low in environment temperature, its volatilization is quite slow, can not be formed with certain density gas phase protection layer on every side at packing material within a certain period of time, does not reach the requirement of sterilization, thereby does not also just have fresh-keeping effect.
The purpose of this invention is to provide a kind of deoxidizing antistaling agent that has above-mentioned two class antistaling agent effects concurrently, it can remove the oxygen in the packing material effectively, suppresses microbial growth, can kill the bacterium in the packing material again effectively.
The objective of the invention is to realize by following technical solution:
By weight percentage:
Get 80～200 purpose iron powders (can be reduced iron powder or cast iron powder) 40-60%;
Salt (CaCL
2Or NaCL) 0.4-2.5%;
200 purpose active carbon 0.2-3.5%;
12-14 purpose quick lime (CaO) 1-3%;
Water (H
2O) 8-16%;
Dimethyl fumarate 3-15%;
12-14 purpose cinder (or bentonite/zeolite) 47.4-0%.
Operation as follows:
1) salt is contained in the entry stirred, till dissolving;
2) get cinder (or bentonite, zeolite) and stir (available sugar coating machine stirred 3～5 minutes) with active carbon, quick lime, auxiliary agent;
3) salt solution with the step 1) gained sprays into step 2) in the gained auxiliary agent, stir while spraying into;
4) compound with the step 3) gained adds dimethyl fumarate and iron powder (reduced iron powder or cast iron powder), stirred for several minute (available sugar coating machine stirred 3～5 minutes), pack with wrapping paper then with certain air permeability, with the good outer packaging bag sealing of air-tightness, promptly get deoxidizing antistaling agent of the present invention again.
Advantage of the present invention is; open outer packaging bag during use; be placed in the packaged food bag (external packing of food bag is polyester/polyethylene or the compound air-tight package of nylon/polyethylene preferably); then this deoxidizing antistaling agent begins to absorb wherein oxygen and while release heat; a bag interior temperature is raise; then promote the volatilization of dimethyl fumarate wherein, in bag, form the gas phase protection layer, kill microorganism wherein simultaneously.When being in anaerobic state in the bag, not only can stop wherein microbial growth breeding effectively, can also prevent the food oil lipid oxidation, the nutrition deterioration.Realized the double effects of the fresh-keeping and sterilization fresh-keeping of deoxidation.
Below in conjunction with two embodiment of the present invention advantage of the present invention is described further:
By above-mentioned technical solution, get iron powder 40 grams, the NaCL0.5 gram, water 8 grams, active carbon 0.7 gram, dimethyl fumarate 3 grams, cinder 46.8 grams, quick lime 1 is restrained into deoxidizing antistaling agent A of the present invention; Get iron powder 60 grams again, CaCL
22 grams, water 15 grams, active carbon 2 grams, dimethyl fumarate 10 grams, bentonite/zeolite 8 grams, quick lime 3 grams are made deoxidizing antistaling agent B.A, B dideoxy antistaling agent and existing deoxidier are done the contrast experiment.Getting existing deoxidier C(gets its component and is: iron powder 50 grams, NaCL1 gram, water 9 grams, active carbon 3 grams, cinder 15 grams, bentonite/zeolite 20 grams, quick lime 2 grams), getting existing its component of antistaling agent D(is dimethyl fumarate 15 grams).With above-mentioned A, B, (it is 40ml/M that wrapping paper all adopts air permeability to each even packing 20 parcel of four kinds of antistaling agents of C, D
224 hours, specification was that the composite paper-plastic material of 4 * 5cm is made), respectively get 18 parcels and be positioned over respectively in the packaging bag of moon cake that does not contain any anticorrisive agent.Packaging bag of moon cake is divided into polyester/polyethylene. polypropylene, polyethylene. and three kinds of polyethylene, the moon cake of respectively getting three kinds of packaging bags is one group for 6 bags, gets four groups altogether, totally 72 bags, four group # are I, II, III, IV.Wherein put into A in the I group, put into B in the II group, put into C in the III group, put into D in the IV group, carry out the nature shelf test after all sealing, experimental period is 3 months, and test temperature is 20 ℃～32 ℃, and result of the test is seen attached list.Can see that from table the deoxidizing antistaling agent A, the B that produce according to technical solution of the present invention to the moon cake of three kinds of packaging material, deposit and still can keep the former flavoursome of moon cake in three months, and as before fresh.And adopt existing antistaling agent C, D, not only to the having relatively high expectations of packaging bag, and fresh-keeping effect is starkly lower than the present invention.The present invention also can be used for the fresh-keeping mildew-resistant of low moisture content article such as tealeaves, medicinal material except that as the food preservative.
