Description
Technical field
The invention belongs to vegetables and fruits packing technique field, a kind of fruit active fresh-keeping ink and its preparation are related in particular to
Technique.
Background technology
China is as vegetables and fruits big country, and types of fruits is various, best in quality, but fruit still can be breathed after harvesting
Heat is released in effect, the oxidation for occurring nutritional ingredient, produces the metabolites such as moisture, carbon dioxide, ethene.In normal temperature, naked put
Under conditions of, the fruits and vegetables effciency of respiratory is high, easily aging, rot, transported according to common plasticses packaging, plastics package is formed
Confined space carbon dioxide, ethene etc. can not be discharged in time, further promote decaying and addling for fruit.
For tropical fruit (tree)s such as Kiwi berry, banana, mango, lichee, it has place of production high temperature, high humidity and some of itself
After-ripening is more easy to after special physiological characteristic, harvesting, is rotted, data display, China is improper due to Preservation Treatment, annual fruit
The rotten proportion of goods damageds are up to 20-25%.
In order to solve tropical fruit (tree) harvesting after storage and transport for long-distance the problem of, at present generally using refrigeration, cold chain transportation
Method, weaken its respiration, but this mode is higher to regional condition and means test requirement, common peasant household is difficult to
Self-built freezer is invested with homestyle.Air regulating fresh-keeping method is also used in the prior art, by adjusting the gas in storage condition
Content ratio, suppresses tropical fruit (tree) respiration, reduces energy loss, or smear antistaling agent, antiseptic etc. in fruit surface
Chemical reagent realizes the fresh-keeping of fruit.But in the above method, controlled atmosphere method is fresh-keeping to add carrying cost, and chemical reagent makes
With can then there is residual in fruit surface, there is certain toxic side effect in the chemical reagent of residual, influence people are healthy.
The content of the invention
Therefore, the technical problems to be solved by the invention are that the fresh-keeping mode cost of traditional fruit is high, had to health
Negative effect, so as to propose that a kind of fruit with low cost, being easy to transport, have no toxic side effect for being prepared in packing case surface is used
Active fresh-keeping ink and its preparation technology.
In order to solve the above technical problems, the technical scheme is that：
The present invention provides a kind of fruit active fresh-keeping ink, and by percentage to the quality, the active fresh-keeping ink is by 60-
70% environment-friendlyink ink and 30-40% active fresh-keeping agent composition.
Preferably, by percentage to the quality, the environment-friendlyink ink is between 65-72% gel type resin, 3-5%
Phthalic acid alkyd resin, 2-3% polyethylene cerate, 18-23% pigment, 2-6% calcium carbonate, 0.3-0.5% it is dry
Drying prescription is constituted.
Preferably, by percentage to the quality, by percentage to the quality, the active fresh-keeping agent by 8.5-12% antibacterial
The starch for the being enclosed with 1- methyl cyclopropenes composition of agent, 45-55% adsorbent and 35-43%.
Preferably, the antiseptic is made up of cinnamon essential oil and chitin, the quality of the cinnamon essential oil and chitin
Than for 1:1-2；The adsorbent is made up of nano silicon, zeolite powder and calcium carbonate, the nano silicon, zeolite
Powder, the mass ratio of calcium carbonate are：7.5-9:7.5-10:40-45.
Preferably, described be enclosed with the starch of 1- methyl cyclopropenes, the load capacity of 1- methyl cyclopropenes is 2-
4wt.%.
Preferably, the porosity of the gel type resin is not more than 3nm, the molecular weight of the polyethylene cerate is
2000-3000。
Preferably, the pigment is one kind in food pigment Monascus color, Gardenia Yellow, gardenia blue, anthocyanidin, light blue
Or multiple combinations, the drier is the dry fat X-10 of E.
Preferably, the nano silicon is food-grade nano silicon, the particle diameter of the nano silicon
For 20-30nm.
The present invention also provides a kind of technique for preparing described fruit active fresh-keeping ink, and it is included environmental protection in proportion
The step of type ink and active fresh-keeping agent are uniformly mixed under 1500-2500rpm rotating speed.
Preferably, the step of also including the fresh-keeping ink being printed in Packaging Box surface.
The above-mentioned technical proposal of the present invention has advantages below compared with prior art：
(1) fruit of the present invention active fresh-keeping ink, by percentage to the quality, the active fresh-keeping ink by
60-70% environment-friendlyink ink and 30-40% active fresh-keeping agent composition.Fresh-keeping ink of the present invention is by nonpoisonous and tasteless
What environment-friendlyink ink and antistaling agent were mixed to prepare, the ink directly can coat or be printed onto packing case inner surface, can be with
Used in surroundings, extend such as banana, the fresh keeping time of Kiwi berry tropical fruit (tree), and its is with low cost, common plantation
Family is that can purchase, and is occupied little space, and is adapted to long-distance transport, compared with traditional cold chain transportation or controlled atmosphere transport, freight
Significantly reduce.
(2) fruit of the present invention active fresh-keeping ink, by percentage to the quality, the environment-friendlyink ink is by 65-
72% gel type resin, 3-5% isophthalic alkyd resin, 2-3% polyethylene cerate, 18-23% pigment, 2-
6% calcium carbonate, 0.3-0.5% drier composition.The ink adhesion is strong, is difficult during storage or fruit transportation
Come off, obtained fresh-keeping corrugated box good quality, fresh-keeping effect continuation is long.
