Abstract
The invention discloses a cordate houttuynia preservation method, in particular relates to a method for preserving cordate houttuynia by using gas packing, belonging to the technical field of agricultural food science. The method aims at the characteristics that cordate houttuynia is subjected to brown stain easily, and the brittleness of the cordate houttuynia is reduced in the cordate houttuynia storage process, and can achieve the preservation by using the gas packing method. The method comprises the steps of cleaning the cordate houttuynia, blowing away part of waste heat, pre-cooling, then placing the cordate houttuynia into ethylene/ethylene vinyl alcohol copolymer freshness protection bags, filling a gas formed by mixing CO2, N2 and O2, carrying out heat sealing, and placing the cordate houttuynia in a refrigeration house being 2+/-1 DEG C for storage. The mixed gas comprises the gases of 20-30% of the CO2, 5-10% of the O2 and the balance being the N2 according to the volume rate. The retain freshness gas mixing accuracy error rate is less than 1.5%; the cordate houttuynia can be stored for 30 days; the edible rate of the cordate houttuynia is more than or equal to 85%.
Description
Technical field
This patent relates to the agricultural food product science and technology field, specifically a kind of cordate houttuynia preservation method of gas flush packaging in conjunction with cryopreservation that use.
Background technology
Efficient fruits and vegetable stock and preserving freshness, to guaranteeing that the fruits and vegetables busy season is not rotten, dull season continuous, enlarging and sell radius, is increased economic efficiency, and realizes the key of " high yield is had a good harvest ".In recent years, along with growth in the living standard, people are more and more higher to the quality requirements of food.Gas regulation package and fresh keeping technology at home and abroad develops rapidly, this type of technology comprises vacuum packaging, gas flush packaging, modified-atmosphere package, gas odor adsorption packing etc., its principle is the physiologically active that the gas componant of by control, packing subenvironment changes to suppress fruits and vegetables, reaches fresh-keeping purpose.
The gas flush packaging technology, by changing fruits and vegetables atmosphere of living in, reaches the purpose that extends fruit vegetables storing period.Gas that this technology adopts mostly is CO
2, O
2and N
2mist, utilize mist to slow down physiological reaction and extending life to the inhibition of microbial bacterial, germ and biological fruit and vegetable reaction.Numerous research shows, CO
2gas has the effect that suppresses most of putrefactivebacterias and fungus growth breeding, is the main antipathogenic composition in protective gas.O
2there are most of anaerobism putrefactivebacteria growth and breedings of inhibition, keep meat color and maintain fresh fruit of vegetables aerobic respiration, keep the effect of freshness.N
2inert gas, inoperative with food, as blanketing gas; Combine use with ethene adsorbent, will form the compound physical preservation technique that cost is low, security performance is high.The key of this technology is the reasonable gas configuration for different fruit and vegetable physiological regulation characteristics.High concentration CO
2can effectively suppress growth of microorganism and fruit and vegetable physiological regulation reaction in the fruit vegetables storing process.But O in mist
2also be absolutely necessary, otherwise will cause the generation of anaerobic respiration, produce ethanol.Therefore, reasonably gas composition is most important to fresh-keeping effect.
The whole herb with root that cordate houttuynia is Saururaceae herbaceos perennial heartleaf houttuynia, have another name called the folding basal part of the ear, purple Ji, hog snout hole, Rhizoma Rohdeae Japonicae etc., be distributed widely in Central China, the southeast and each provinces and regions, southwest, because the fresh goods mouthfeel is crisp, smell is unique is subject to Chuan Deng province, Yunnan-Guizhou consumer and likes, it is very high that cordate houttuynia is rich in protein, grease, vitamins and other nutritious components nutritive value.The effect that simultaneously there is clearing heat and detoxicating, the carbuncle that disappears apocenosis, inducing diuresis for treating strangurtia.The traditional Chinese medical science is applied to the illnesss such as lung carbuncle pyemesis, phlegm heat panting are coughed, hot dysentery, heat pourings, carbuncle sore tumefacting virus, so by health ministry, formally to be defined as be one of the plant resources of great exploitation potential for its of medicine and food.2011, " the Kweiyang folding basal part of the ear " acquisition " Chinese geography sign " authentication.Therefore, the exploitation of cordate houttuynia preservation technique has meaning for expansion sale radius and the shelf life of this fresh and live agricultural product.Cordate houttuynia floods with antistaling agent " a kind of use high concentration CO that fresh-keeping technology has " a kind of processing technology for preserving cordate houttuynia " application number 200910227065.9, by the method for gas flush packaging fruit, has the inventor to invent
2controlled atmospheric packing Kiwi berry preservation method " application number 201310072013.5 but with the application that still belongs to the first time of the cordate houttuynia preservation method of gas flush packaging.
