Cherry is as one of the highest seeds of China's cultivation benefit, since 19 century 70s introduce China, cultivated area constantly expands, especially within nearly 10 years, area increases severely, by expand 2013 to less than 20,000 hectares more than 13.48 ten thousand hectares of 2000, become the advantage cultivation seeds of China some areas (Yantai, Dalian) at present, the market space is huge.For Shandong Province, within 2014, cherry cultivated area has developed into 1,000,000 mu, output 300,000 tons, and the output value 6,000,000,000 yuan accounts for the over half of national cherry industry, and in rapid growth.Along with the increase of output, adopting the classification of rear machinery pre-cold-peace also will become requisite treatment process.In the pre-cold-peace mechanical classification of cherry, as the cold medium of biography and pumped (conveying) medium, there is the risk of meeting water crack fruit more in the water that uses in this course.
Dehiscent fruit is a kind of physical phenomenon that cherry fruit causes pericarp to break due to pericarp absorption moisture increase turgescence.The factor affecting Fruit Cracking mainly contains fruit phenotype feature, pericarp structure feature (stomatal frequency, cutin membrane characteristic and cutin membrane moisture conductance etc.), pericarp tissue mechanical properties etc., affect by inherent cause, outside environmental elements and mineral condition etc. in addition.The quantity of dehiscent fruit and degree, different because of breediness, fruit development stage etc., research is thought, the kind that water absorbing force is strong, fruit face pore is large, stomatal frequency is high and pericarp intensity is low, as the easily dehiscent fruit such as red light, sunshine, Brooks.
If absorption speed and the water absorption of cherry fruit can be reduced, then can reduce cherry fruit meets water crack fruit after adopting risk in pre-cold-peace classification process.Before carrying out the pre-cold-peace mechanical classification of water, by suitable process, reduce the rate of water absorption of fruit, reduce the water absorption of fruit, the risk of dehiscent fruit can be reduced.But in actual production at present, there is no report and the application of these class methods.
Summary of the invention
The present invention is directed to above problem; provide a kind of water-repelling agent and preparation and application thereof of adopting rear dehiscent fruit risk for reducing cherry; develop the water-repelling agent product of edible safety; form the protection of one deck hydrophobic water coating at fruit surface, effectively can reduce the dehiscent fruit risk that fruit imbibition causes.
The technical solution adopted for the present invention to solve the technical problems is: a kind of water-repelling agent adopting rear dehiscent fruit risk for reducing cherry, and the raw material primarily of following weight portion forms: corn oil 12 ~ 18 parts, sucrose ester 6 ~ 9 parts.
For the preparation method of the water-repelling agent of cherry, comprise the following steps:
(1) at normal temperatures and pressures, by formulation ratio, corn oil and sucrose ester are joined in the warm water of 1L, warm water temperature is 40 ~ 60 DEG C, stir with agitator and dissolve completely to sucrose ester for 2 ~ 3 minutes, rotating speed is 300 ~ 850 revs/min, corn oil is dispersed in solution, is mixed with homogeneous white mother liquor;
(2) added by the mother liquor configured in 149 ~ 199L normal temperature clear water, mixer stirs 2 ~ 3 minutes, and rotating speed is 3000 ~ 5000 revs/min, obtains the water-repelling agent of uniformity.
For the using method of the water-repelling agent of cherry, cherry fruit to be immersed or with the water-repelling agent spray prepared, leaching fruit or spray time 1 minute, and then carry out water pre-cold-peace classification process.
Corn oil processes obtained vegetable fat by maize, unsaturated fatty acid content is up to 80% ~ 85%, main component linoleic acid is essential fatty acid, it is the part forming human body cell, can combine with cholesterol in human body, have the effect of preventing and treating the angiocardiopathies such as atherosclerotic; Sitosterol in corn oil has the effect reducing cholesterol; Corn oil is rich in vitamin E, Wheat Protein.Due to corn oil be of high nutritive value, mouthfeel is good, not perishable, also because it is as clear as crystal, light taste, deeply popular to people without special bad smell.In American-European countries, corn oil is extensively eaten by as a kind of table oil, enjoys the laudatory title such as " healthy oil ", " relieved oil ", " long life oil ".
Emulsifying agent forms the third material added needed for stable emulsion when referring to and can make two kinds of immiscible liquid mixing.It can make electric charge on dispersed phase drop band, and between dispersed phase drop, identical charges is mutually exclusive; Reduce the interfacial tension between decentralized photo and decentralized medium, interface is formed the diaphragm with certain mechanical strength, thus prevents the mutually coalescent of dispersed phase drop, ensure that the stable existence of emulsion.That existence with drops in emulsion is called decentralized photo mutually, or is called interior phase, discontinuous phase; And another joining together is called decentralized medium mutually, or be called foreign minister, continuous phase.Two kinds of not miscible liquid, during as water and oil phase mixing, can form the emulsion of two types, i.e. oil-in-water type (O/W) and water-in-oil type (W/O) emulsion.Foreign minister is water, interior mutually for the emulsion of oil is called oil-in-water emulsion, otherwise, foreign minister be oil, interior be that the emulsion of water is called WO emulsion mutually.
The nonionic emulsifier that sucrose fatty ester (sucrose ester) is take sucrose as hydrophilic radical, aliphatic acid is hydrophobic grouping, belongs to oil-in-water (O/W) type emulsifying agent.Sucrose ester has good emulsification to oil and water, sucrose ester is non-toxic, odorless, colourless, tasteless, human body skin is had no stimulation, there is good emulsification, dispersion, solubilising, the numerous characteristics such as wetting, fresh-keeping, the fields such as food, medicine, cosmetics, sugaring, preserving fruit and vegetable utilizing, chemical fertilizer and feed can be widely used in.Sucrose ester becomes sucrose after being hydrolyzed and edible fat acid has nutritive value.Different from the surfactant generally synthesize, sucrose ester can biodegradation under the condition of aerobic and anaerobism, and this brings convenience to the process of environment, is a kind of green surfactant.
Cherry is for eating fruit raw, and consumer cleans rear directly edible, and therefore the material of water-repelling agent must edible safety, water-repelling agent material (corn oil and the sucrose ester) wide material sources that the present invention selects, with low cost, without any side effects to human body, nuisanceless to environment.
The present invention is easy and simple to handle, to reducing the effective of cherry fruit absorption speed and water absorption, contributing to reducing the Fruit Cracking in the pre-cold-peace classification of fruit, being suitable for production application.
