Description
Technical field
The present invention relates to a kind of new method of fruit fresh-keeping, particularly a kind of new method that suppresses the brown stain of yellow hat worn by a Taoist priest the operatic circle skin.
Background technology
At the yellow hat worn by a Taoist priest pears are the important pear cultivation kinds of China; Its fruit is satisfactory, pulp is pure white, and meat is fine and smooth, crisp, and local flavor sour-sweet is moderate and have strong fragrance; Receive consumers in general's favor, the yellow hat worn by a Taoist priest pears have become the principal item of China's production, processing and export abroad.Yet the yellow hat worn by a Taoist priest pears are in maturity period and storage early stage, and fruit surface is prone to the pericarp foxiness takes place, appear irregularly shaped, like shank, so name " shank disease ".Sick fruit exterior quality extreme difference, commodity value reduces greatly, often orchard worker and fresh-keeping enterprise is caused very large economy loss.
In order to keep the quality of yellow hat worn by a Taoist priest pears, need be cooled to as early as possible about 0 ℃ after adopting, be that shank is sick yet adopt back rapid cooling can obviously increase the weight of to occur again pericarp browning.
The new method of yellow hat worn by a Taoist priest the operatic circle skin brown stain mainly is slow cooling in preventing to preserve in the commodity production at present; This method has suppressed the brown stain of pericarp more effectively, but its operation bothers, and cooling needs 15～20 days; Because cooling is slow; The pears quality obviously reduces, and storage later stage or outbound shelf stage rotting rate, the withered rate of carpopodium are all higher, and the fruit taste is also bad.
In the document at home and abroad, less about the information that suppresses the brown stain of yellow hat worn by a Taoist priest pears postharvest storage mesocarp, the new method that alleviates pericarp browning also has precooling, controlled atmosphere, soaks calcium, 1-MCP handles etc., and having single method to handle also has complex method to handle.Precooling treatment is the yellow hat worn by a Taoist priest pears to be put in be higher than under the reserve temperature condition, for example 8 ℃, after 5～10 days, reduce to low temperature again, and the method is similar to slow cooling, also is to alleviate brown stain through alleviating thermal stimulus, and the cooling of this method is slow, and complex operation influences the quality of pears.Forefathers use too high CO in test
2Exudative type PE preservative film, common PE preservative film, modified form PVC fresh-preserving film, functional low-density polyethylene film, polyvinyl chloride preservative film carry out controlled atmosphere to be handled; Controlled atmosphere is handled the brown stain that has alleviated yellow hat worn by a Taoist priest the operatic circle skin to a certain extent; But the controlled atmosphere method is had relatively high expectations to packaging material, packing method, so effect is limited.Calcium ability delayed fruit is old and feeble, reduces physiological disease, suppresses the inner brown stain of fruit.One Chinese patent application CN200910227838.3 has reported that soaking calcium handles and can alleviate the brown stain of yellow hat worn by a Taoist priest the operatic circle skin, apple after the harvesting discovered, pears is arranged with 500～1000 nLL
-1Stifling 18～24 hours of 1-MCP, and then with 3～6% CaCl
2Aqueous solution soaking 3～5 minutes, pull drying out after, by conventional method refrigeration, this compound new method has kept good storage quality, but prevents that the pericarp browning effect is limited, and the operation hell to pay.One Chinese patent application CN102132724 discloses and has adopted the stifling pericarp browning that suppresses the yellow hat worn by a Taoist priest pears of ethylene gas, and effect is obvious, but this processing needs to carry out under the relative air-proof condition.One Chinese patent application CN101990935 discloses the yellow hat worn by a Taoist priest pears and has adopted the first application of vacuum in back, and then cooling method suppresses the pericarp browning of yellow hat worn by a Taoist priest pears under the condition of normal pressure, and patented method uses needs vaccum-pumping equipment, complicated operation, cost height.One Chinese patent application CN102077863 discloses use 0.5-10% sodium chloride solution and has carried out immersion treatment inhibition yellow hat worn by a Taoist priest pears 0.5-5h, can obviously suppress the brown stain of yellow hat worn by a Taoist priest the operatic circle skin, and there be trouble, the residual problem of salt marsh used in this method.
