Abstract
The invention relates to a fruit preservation method, and concretely provides a red fragrant pear storage fresh-keeping method. Harvested red fragrant pear fruits are immersed in a chlorine dioxide solution and then are subjected to ventilation, air drying, packaging and precooling; the 1-MCP sustained release agent and a potassium permanganate ethene remover are added, mixed gases of oxygen, carbon dioxide and nitrogen are inputted into an air regulating box, and air regulating storage is carried out. The red fragrant pear storage fresh-keeping method combines physical and chemical methods, air regulating fresh-keeping storage of red fragrant pear fruits is carried out, fresh-keeping red fragrant pear fruits are stored for 8-10 months, color and fragrance of fruits at harvest are kept basically within 10 shelf days after warehouse-out, yellowing of pericarp is delayed obviously, the fruit rotting rate is lowered, and quality and flavor of fruits are kept.
Description
Technical field
The present invention relates to a kind of fruit method for preserving, be specially red radish method for storing and refreshing.
Background technology
Red radish be Zhengzhou Fruit-tree Inst., Chinese Agriculture Science Academy with Kuerle delicious pear and goose pears cross breeding, be one of development in recent years excellent new varieties of red skin pears of getting up.Mean fruit weight is about 220g, long oval or spindle, pericarp background color yellow green, and sunny slope is blush, or changes yellow into gradually, and core is little, and meat is crisp, and fragrant and sweet taste is dense, best in quality, dark liking by consumers in general.At present in Shanxi, all there is cultivation on Shaanxi, Hebei, Shandong, Beijing, the ground such as Liaoning, and output and area increase year by year.Red radish is storage tolerance comparatively, but anaphase storage or after taking out from freezer shelf or In transit pericarp turn yellow gradually by green, have impact on storage quality and the commodity value of fruit, because green red radish is more liked by consumer, along with the prolongation of storage time, it is the key technical problem affecting these pears storage sale that pericarp turns Huang, and core also has brown stain simultaneously, also have impact on sale to a certain extent, cause certain loss to storage enterprise and orchard worker.In current production, the main storage technique of red radish is conventional refrigeration, after the vanning of red radish picking fruit, is directly positioned over 0 ~ 1 DEG C of freezer and preserves.Although use this technology also can by red radish fruit storage 6-7 month, the fruit of outbound, shelf life be short, and it is fast that pericarp turns yellow degree, and fruit rot rate is up to 25-30%, and taste of fruit declines obviously.
Summary of the invention
For above-mentioned technical problem, the invention provides a kind of preservation method turning Huang that can extend the red radish fruit storage time, delay pericarp.Concrete technical scheme is:
Red radish method for storing and refreshing, comprises the following steps:
(1) gather: select 7-8 maturation without disease and pest, without bump injury, really gather without rotten red radish; And subsequent treatment was carried out in 6-18 hour;
(2) anticorrosion: the red radish fruit of gathering to be soaked in the ClO 2 solution of 30 ~ 50mg/L fruit 3-7min; Place the place of shady and cool ventilation after fruit immersion liquid, dry liquid, time controling is in 18-30 hour;
(3) pack: the red radish fruit after preservative treatment is loaded in the thick polyethylene film freshness protection package of 0.01-0.03mm, uncovered placement;
(4) precooling: after gathering in 24-48 hour, puts into fore-cooling room and carries out precooling by fruit, precooling temperature is 1-5 DEG C;
(5) air conditioned storage: the red radish fruit after precooling puts into air-conditioning preservation box, in polyethylene freshness protection package, put into 1-MCP sustained release agent and potassium permanganate ethylene scavenger simultaneously, by freshness protection package Mian Kou, sealing air regulating box, oxygen is passed in air regulating box, the mist of carbon dioxide and nitrogen, gas flow is 150mL/min, air-conditioning preservation box being placed on temperature is carry out air conditioned storage in the freezer of 0 ~ 1 DEG C, in air regulating box, the concentration of oxygen controls 3% ~ 5%, the concentration of carbon dioxide controls 2% ~ 3%, nitrogen gas concn is 92%-95%, gas componant adopts Italian COMBO280GasAnalyser to measure.
Red radish method for storing and refreshing provided by the invention, the method of physics and chemistry is adopted to combine, controlled atmosphere storage is carried out to red radish fruit, fresh-keeping red radish fruit storage 8-10 month, after outbound within shelf 10 days, the color, smell and taste of basic fruit when keeping gathering, obviously delay turning of pericarp yellow, reduce fruit rot rate, keep quality and the local flavor of fruit.With 1-methyl cyclopropene sustained release agent and potassium permanganate ethylene scavenger, suppress to greatest extent and absorb ethene, reaching the object of delayed fruit aging.
