In order to solve above-mentioned technical problem, the technical solution adopted in the present invention is:
(1) weigh and put into juice extractor after 4～5kg Fructus Citri Limoniaes are peeled and squeeze the juice, remove filtering residue by the filtered through gauze of 200 mesh and obtain filtrate, isolated supernatant after filtrate is centrifuged 10～15min with horizontal centrifuge with 4000～5000r/min rotating speeds will be obtained；
(2) supernatant measuring 800～900mL above-mentioned isolateds is poured in beaker, 100～200g Pericarppium arachidis hypogaeaes are added again in beaker, it is placed in sonic oscillation instrument with 200～300W power ultrasonic vibration dippings 8～10h, is filtrated to get softening Pericarppium arachidis hypogaeae carrier, standby after naturally drying；
(3) for 1:20 glacial acetic acid and deionized water mix homogeneously are obtained acetum by volume, then in acetum, add its quality 8～the chitosan of 10% and 5～15% glycerol, be placed on magnetic stirrer and be stirred mixing with 500～600r/min rotating speeds；
(4) during above-mentioned stirring, add mixed liquor gross mass 2～4% sodium alginate and 3～5% calcium chloride, continue stirring until mixed liquor is gel in beaker, again gel mixed liquor is put in vacuum concentration pot, reduction pressure inside the tank, to 900～1000Pa, is concentrated under reduced pressure to give the acid-soluble Chitosan-coated liquid of thickness；
(5) for 3:1:20, sodium chlorite, the above-mentioned standby Pericarppium arachidis hypogaeae carrier that softens are loaded in vortex oscillation instrument together with the acid-soluble Chitosan-coated liquid of thickness by volume, with 40～50W power vortex vibration dippings 2～3h, be filtrated to get filtering residue；
(6) filtering residue obtained above is put into vacuum freeze-drying machine, lyophilizing 3～5h at-50～-40 DEG C, put into after taking-up after jet mill is pulverized and cross 100 mesh standard sieves, after packaging, i.e. obtain biomass slow released ClO 2 antistaling agent.
The application process of the present invention: the biomass slow released ClO 2 antistaling agent present invention prepared carries out being configured to antistaling agent solution by 3～5g/L, fruit is immersed in antistaling agent solution, natural drying after soaking 5～10min, put in the plastic bag preparing antistaling agent equipped with the present invention after drying, every kilogram of fruit dosing 1～3g antistaling agent, can make the fruit freshness preserving time improve 30～40 days.
The invention has the beneficial effects as follows:
(1) present invention utilizes softening Pericarppium arachidis hypogaeae to be carrier, by acid-soluble Chitosan-coated liquid cladding chlorine dioxide back loading in the carrier, improves the stability of chlorine dioxide, can store for a long time；
(2) antistaling agent prepared by the present invention can slowly release chlorine dioxide within a certain period of time, easy to use, antibacterial the most thorough, can play the effect of long-time sterilization；
(3) present invention prepares raw material environmental friendliness, has no side effect human non-toxic and will not produce secondary pollution.

Example 3
First weigh and put into juice extractor after 5kg Fructus Citri Limoniae is peeled and squeeze the juice, remove filtering residue by the filtered through gauze of 200 mesh and obtain filtrate, filtrate will be obtained and be centrifuged isolated supernatant after 15min with horizontal centrifuge with 5000r/min rotating speed；The supernatant measuring the above-mentioned isolated of 900mL is poured in beaker, then adds 200g Pericarppium arachidis hypogaeae in beaker, is placed in sonic oscillation instrument with 300W power ultrasonic vibration dipping 10h, is filtrated to get softening Pericarppium arachidis hypogaeae carrier, standby after naturally drying；For 1:20 glacial acetic acid and deionized water mix homogeneously are obtained acetum by volume, then in acetum, add chitosan and 15% glycerol of its quality 10%, be placed on magnetic stirrer and be stirred mixing with 600r/min rotating speed；Mixed liquor gross mass 4% sodium alginate and 5% calcium chloride is added during above-mentioned stirring, continue stirring until mixed liquor is gel in beaker, putting in vacuum concentration pot by gel mixed liquor again, reduction pressure inside the tank, to 1000Pa, is concentrated under reduced pressure to give the acid-soluble Chitosan-coated liquid of thickness；For 3:1:20, sodium chlorite, the above-mentioned standby Pericarppium arachidis hypogaeae carrier that softens are loaded in vortex oscillation instrument together with the acid-soluble Chitosan-coated liquid of thickness by volume, with 50W power vortex vibration dipping 3h, be filtrated to get filtering residue；Filtering residue obtained above is put into vacuum freeze-drying machine, lyophilizing 5h at-40 DEG C, puts into after taking-up after jet mill is pulverized and crosses 100 mesh standard sieves, i.e. obtain biomass slow released ClO 2 antistaling agent after packaging.
The biomass slow released ClO 2 antistaling agent present invention prepared is carried out being configured to antistaling agent solution by 5g/L, fruit is immersed in antistaling agent solution, soak natural drying after 10min, put in the plastic bag of the antistaling agent prepared equipped with the present invention after drying, every kilogram of fruit dosing 3g antistaling agent, can make the fruit freshness preserving time improve 40 days.
Claims (1)
