Abstract
The invention discloses a preservation and freshness method for bananas, comprising the steps of: a, harvesting bananas with ripeness of 70-80%, separating the bananas individually, selecting bananas with uniform size, no plant disease and insect pests and mechanical injury, cutting the banana heads neatly, cleaning and airing; and b, soaking the aired bananas in the step a in a preservative for 5-15 minutes, then airing, and packing and storing, wherein per liter of the preservative comprises 5-20mg of N-(2-chloro-4-pyridyl)-N-phenylurea (CPPU) and 10-100mg of gibberellin (GA3). The bananas treated by the method disclosed by the invention can be stored for 90days at the temperature of 25 DEG C, the healthy fruit rate is over 95%, and the fruit quality and flavor can be well kept, so bananas treated by compounding a proper amount of CPPU and GA3 have a good color and luster change control effect, thus a certain technical support is provided for the application of the compounded CPPU and GA3 in pretreatment and posttreatment of fruits and vegetables, particularly in storage after harvesting, keeping freshness and prolonging the shelf life of dark green fruits and vegetables to achieve a fresh-keeping effect.
Description
Technical field:
The invention belongs to the preserving fruit and vegetable utilizing field, be specifically related to a kind of banana storage preservation method.
Background technology:
Banana (Musa spp., AAA group, cv. ' Brazil ') is to originate in the southeast, Asia, abounds with in the torrid zone, semi-tropical characteristic fruit, and be one of large fruit in the world four (citrus, banana, grape, apple).Banana is rich in the nutriments such as carbohydrate, protein, mineral matter, vitamin.Research in recent years finds that banana also contains norepinephrine (Noradrenaline), serotonin (Serotonin), the physiological activators such as dopamine (Dopamine), therefore, banana is the healthy food of a kind of only polydipsia, moistening lung intestines, promoting blood circulation, replenishing essence marrow, the effect such as hypotensive.Banana is transition type fruit, show the obvious dark green flavous change color feature that becomes in maturation, and the aggravation along with maturity, brownization stigma very easily occurs in the pericarp surface, last fruit and pericarp addle together, cause shelf life to shorten and commodity value decline, therefore carry out banana fresh-keeping research important in inhibiting.At present both at home and abroad banana fresh-keeping method have that deepfreeze, chemical agent are anticorrosion, controlled atmosphere and radiation preservation etc.
In the Banana after ripening, the color and luster variation is an irreversible chlorophyll degradation chlorisis physiology course; The color and lusters such as carotenoid of the yellow of originally covering are presented, and are also simultaneously the old and feeble signs that occurs.The process in coupling of being close to that it has been generally acknowledged that banana is ripe softening and the pericarp chlorisis occurs together, but when running into that the external environment factor stimulates or during relevant treatment, greenly can postpone or accelerate to degrade, and the undesired after ripening such as occurs damaging to plants caused by sudden drop in temperature, rascal is ripe.Chlorophyll degradation may be controlled relevantly with a series of chlorophyll degradation enzymes, but also is subject to some metabolins such as solubility small molecular sugar glucose, fructose, the adjusting of biological regulator such as the basic element of cell division (cytokinins, CKs) simultaneously.In these physiological reactions, the chloroplaset aging can not be normally photosynthetic, the green disappearance; The antioxidant system of pericarp tissue self destroys, active oxygen breaks out, foxiness occurs; Defence capability weakens, fungal infection etc.
N-(2-chloro-4-pyridine)-nitrogen-phenylurea (Phenylurea, N-(2-chloro-4-pyridil)-N '-phenylurea, CPPU) be a kind of artificial synthetic similar thing of the basic element of cell division, has very strong cytokine activity, can promote cell division, chlorophyll to synthesize, improve fruit-setting rate and expand, strengthening resistance obvious with the texts that delays senility.It is widely used in Fruit pre-treatment such as grape, Kiwi berry, cherry etc. to increase fruit yield, keeps quality after Fruit.
Gibberellin is a plant growth regulators, be mainly used on agriculture, woods, gardening promoting growing, enlarge leaf area, accelerate the sprout growth, suppressing ripe and old and feeble of crop, control the effects such as formation of lateral bud dormancy and stem tuber, extensive use on cotton, grape, potato, fruit, vegetables.
Summary of the invention:
The purpose of this invention is to provide a kind of banana storage preservation method that can effectively control the banana postharvest senescence and keep fruit quality.
Banana storage preservation method of the present invention, is characterized in that, comprises the following steps:
A, gather seven to medium well banana, every comb banana is divided into single any of several broadleaf plants and refers to, selects big or small homogeneous, without the banana of disease and pest, mechanical damage, cuts flat any of several broadleaf plants and refers to clean, and dries;
B, the banana after the drying of step a is placed in antistaling agent soaks 5～15min, then dry the packing storage;
Described antistaling agent is every liter and contains N-(2-chloro-4-pyridine)-nitrogen-phenylurea 5～20mg and gibberellin 10～100mg.
The drying of described step a and step b is preferably that to dry temperature be 25 ℃, and flash-off time is 0.5～1 hour.
Described packing storage is preferably with the thick sealed polyethylene plastic bag of 0.03mm packs, and is placed in 25 ℃, preserves in the room temperature of 70～90% humidity.Excess Temperature can shorten fresh keeping time, and the ripe phenomenon of rascal appears in banana.
Every liter of antistaling agent of the present invention is so prepared: the N-of 5-20mg (2-chloro-4-pyridine)-nitrogen-phenylurea (CPPU) is dissolved in the 20ml absolute ethyl alcohol, add appropriate water, and then add the gibberellin of 10～100mg, then water is settled to 1000ml, obtains antistaling agent.
After banana is adopted, soon, ethene generates in a large number, causes the rapid flavescence of Banana peel, and chlorophyll reduces, the rapid deliquescing of pulp, loses commodity value.the inventor finds, banana color and luster and chlorophyll content are closely related, N-(2-chloro-4-pyridine)-nitrogen-phenylurea (CPPU) may competitiveness act on cytokinin oxidase (CKX) as the basic element of cell division (CTK) analog, analyze the physiological change relation of the variation of ripening of fruits chlorophyll degradation and CTK, the present invention utilizes the external processing banana of using of the compound GA3 of CPPU, result shows the soluble sugar content in Banana peel, chlorophyll, a series of pericarp antioxidation activities change, and CTK content all changes, use the banana after the present invention processes to preserve 90d under 25 ℃, good fruit rate is more than 95%, it is better that fruit quality and local flavor can keep, this shows, the compound GA3 processing of the addition of C PPU is adopted rear banana and is had effect preferably to controlling its color and luster variation, for being applied in before fruits and vegetables are adopted, the compound GA3 of CPPU adopts post processing, especially dark green type postharvest fruit and vegetable storage, delay senility, Shelf-life, thereby reach fresh-keeping effect, certain technical support is provided.
The antistaling agent of applying in the present invention is phytocytomine analog CPPU and gibberellin GA3 solution, and these two kinds of materials are to slow down the respiratory metabolism of fruit in storage, delaying the minimizing of pericarp Determination of Chlorophyll for the principle of banana fresh-keeping.Also these two kinds of materials of report confirmation are not harmful, therefore safe at present.
The present invention is simple to operate, need not large equipment investment, can use on a large scale on producing, and has a good application prospect.
