Abstract
The invention relates to a medlar mould proof color fixative which comprises components by weight percentage: 0.08-0.12% of ethyl p-hydroxybenzaote sodium, 0.16-0.24% of propylparaben sodium, 1.00-2.00% of iso-ascorbyl sodium, 0.50-0.75% of EDTA-2Na, 1.00-1.50% of sodium pyrophosphate and the balance of water; the medlar mould proof color fixative adopts the sodium salt of hydroxybenzoic acid ester mildewproof agent, has low toxicity, non-sulphur residual, good water-solubility and high efficient inhibiting effect on the mould which cause medlar to mildew; the iso-ascorbyl sodium, the EDTA-2Na and the sodium pyrophosphate which have very good color-preserving effect on the medlar pigment has better color-preserving effect; and the selected mildewproof agent and the color fixative can be well combined and has no influence on the effect with each other after being combined.
Description
Technical field
The present invention relates to the postharvest technology of fruits and vegetables field.
Background technology
At present also be not exclusively used in the composite food additive that medlar mould proof protects look, the disqualification rate after matrimony vine is drying is about 20%, and the peasant is in order to reduce the loss, and the matrimony vine that will go mouldy is used sulfur fumigation, and through the matrimony vine of sulfur fumigation, SO
2Residual quantity is more than 20 times of permission residual quantity≤50mg/kg index that GB GB/T 18672-2002 matrimony vine (fruit of Chinese wolfberry) standard is clearly stipulated all above 1000mg/kg, becomes " the malicious matrimony vine " of " red skin evil mind ".
Ripe Chinese wolfberry fruit water content height, characteristics such as the meat softness easily is extruded, sugar content height make matrimony vine be easy to be gone mouldy by infected by microbes in drying and storing process.The composition of wolfberry pigment is the fatty oil carotene compounds, makes matrimony vine present redness, wherein the content of beta carotene about 90% very easily oxidized because beta carotene contains a large amount of unsaturated bonds, light fugitive and to thermally labile.In utilizing the drying process of heliotechnics, canopy temperature can reach 50 ℃～60 ℃, and light intensity can reach more than the 1300uw/cm2, and wolfberry pigment is oxidation Decomposition very easily with this understanding, and black fruit rate is higher.
In the actual production, the peasant generally adopts the method reduction of sulfur fumigation to go mouldy, and causes the content of sulfur dioxide severe overweight.
Chinese patent 200610163494 (application number) discloses a kind of color-fixing wax-removing agent of lycium barbarum, this protects the look dewaxing agent and is made up of sodium acid carbonate, potassium sorbate, natrium citricum, Sodium Benzoate, natrium nitrosum, main component is a sodium acid carbonate in this patent, main effect is dewaxing, employed mould inhibitor is a potassium sorbate, according to our laboratory research, potassium sorbate is not remarkable to the anti-effect of going mouldy of the main bacteria seed that causes matrimony vine and go mouldy, and excessive concentration, its residual quantity easily exceeds standard, and cost is higher, is difficult for promoting.
Chinese patent 200810133860 (application number) discloses a kind of agent special for protecting color and making dried medlar, and raw material is edible soda ash, natrium citricum, sodium iso-vc and potassium sorbate, and color stabilizer does not wherein have clear and definite proportion relation, does not promptly have the best look proportioning of protecting to make up.
Summary of the invention
The purpose of this invention is to provide a kind of medlar mould proof color fixative.
The present invention is a kind of medlar mould proof color fixative, by mass percentage, its component is: nipagin A sodium 0.08～0.12%, Sodium Propyl Hydroxybenzoate 0.16～0.24%, different Vc sodium 1.00～2.00%, EDTA-2Na0.50～0.75%, sodium pyrophosphate 1.00～1.50%, surplus is a water.
The using method that the present invention relates to is that this solution evenly is sprayed on the matrimony vine surface in sprayer.
Characteristics of the present invention are: 1. adopt the sodium salt of parabens mould inhibitor, and low toxicity, no sulphur is residual, and good water solubility, at causing that the mould that matrimony vine goes mouldy has efficient inhibitory action; 2. select the different Vc sodium, EDTA-2Na and the sodium pyrophosphate that wolfberry pigment there are fine color-protecting function for use, it is better to protect chromatic effect; 3. selected mould inhibitor and color stabilizer can be compound well, and compound back does not have influence to effect each other.
Description of drawings
Fig. 1～3rd, the present invention uses the aqueous solution of 1% anticorrisive agent to causing the fungistatic effect figure of the main mould that matrimony vine goes mouldy in the experiment, and the employing diameter is that the filter paper of 8mm is done bacteriostatic experiment.
Fig. 1 is the present invention to the fungistatic effect figure of the main mould (the commissure spore is mould) that causes matrimony vine and go mouldy, and the inhibition zone mean size is: 5.7mm has fairly obvious fungistatic effect.
Fig. 2 is the present invention to the fungistatic effect figure of the main mould (branch is mould) that causes matrimony vine and go mouldy, and the inhibition zone mean size is: 4.7mm has fairly obvious fungistatic effect.
Fig. 3 is the present invention to the fungistatic effect figure of the main mould (Mucor) that causes matrimony vine and go mouldy, and the inhibition zone mean size is: 4.5mm, fungistatic effect is obvious.
The specific embodiment
The present invention is a kind of medlar mould proof color fixative, by mass percentage, its component is: nipagin A sodium 0.08～0.12%, Sodium Propyl Hydroxybenzoate 0.16～0.24%, different Vc sodium 1.00～2.00%, EDTA-2Na0.50～0.75%, sodium pyrophosphate 1.00～1.50%, surplus is a water.
Further launch the present invention below in conjunction with specific embodiment.
Embodiment 1:
When overcast and rainy, the mass concentration percentage of each component of medlar mould proof color fixative of the present invention is: nipagin A sodium 0.12%, Sodium Propyl Hydroxybenzoate 0.24%, different Vc sodium 2.00%, EDTA-2Na 0.75%, sodium pyrophosphate 1.00%.New fresh fructus lycii is dipped in 10 seconds in the solution, places 35 ℃ of mean temperatures, relative humidity 99% is observed mould variable Rate under the condition of lucifuge sealing.Experimental result shows: compare with control group, can postpone the matrimony vine mouldy time is 18 hours; In the time of 48 hours, reduce the mould variability 30% of matrimony vine; In the time of 72 hours, reduce the mould variability about 22% of matrimony vine than control group.
Embodiment 2:
During with sunny weather, the mass concentration percentage of each component of medlar mould proof color fixative of the present invention is: nipagin A sodium 0.08%, Sodium Propyl Hydroxybenzoate 0.16%, different Vc sodium 1.00%, EDTA-2Na 0.50%, sodium pyrophosphate 1.50%.New fresh fructus lycii is dipped in 10 seconds in the solution, places under the sunshine dry.Experimental result shows: compare with control group, the matrimony vine color after drying is pure, and color and luster is even, and oil fruit, black fruit rate reduce by 85%～95%.
