Abstract

A kind of preprocess method before being dried the invention discloses day lily barn, it includes:Biological preservation liquid first is configured to boiling water, Natamycin and the kojic acid after cooling, and the day lily of harvesting is soaked 20~30 minutes in biological preservation liquid, pulls out, pack and store 1~2 day at room temperature, suppress to bloom.Then it is configured to chlorisis agent with Natamycin, kojic acid, 40% ethephon agent and jasmonic ketone methyl esters.Under room temperature condition, the day lily that the ability of blooming is lost through aforementioned processing is immersed in chlorisis agent 1~2 hour, pulled out, sealing storage 2~3 days takes off green, yellow is presented.The present invention under cryogenic, using biological species food additives, it is to avoid food-safety problem caused by chemical addition agent;The inventive method is simple, and processing cost is low, is adapted to rural area peasant household, little Wei enterprises and Large-scale enterprises application.

Description

A kind of preprocess method before day lily barn drying
Technical field
The present invention relates to the preprocess method that a kind of day lily is dried, the pre- place before particularly a kind of day lily barn drying Reason method.
Background technology
Day lily(Hemerocallis Fulvs)Also known as day lily, popular name datlily, it is that Liliaceae perennial herb is planted Thing, its edible part is bud, is the Specialty vegetable of China.Day lily is of high nutritive value, containing carbohydrate, protein, vitamin, nothing Machine salt and a variety of amino acid needed by human, delicious flavour, the good reputation for having the king of vegetables, are loved by consumers.
Discuss day lily cultivated area produces 240000 tons of fresh vegetable per year up to 160,000 mu, and more than 800,000,000 yuan of the gross output value accounts for complete The 28.9% of county's planting industry gross output value, more than 40 ten thousand vegetable growers are engaged in day lily industry, vegetable grower's per capita net income up to more than 5000 yuan, into For the pillar industry of Qidong County, Qidong day lily in 2016 obtains geography symbol product title and protected, and day lily has turned into One loud business card of Qidong County.
High temperature season, day lily easily blooms after adopting, rotted, it is difficult to fresh-keeping, therefore, Qidong County day lily it is main with Based on processing sell dry vegetalbe.In the case that harvesting amount is less, peasant household suppresses to bloom with steamer blanching fixing day lily, then daylight Under ted processing dry vegetalbe, this method each household can only process 50~100kg fresh vegetables daily.At present, the fresh vegetable amount of collecting season is put down Daily up to 4 kilotons, peak period is up to 30,000 tons, and company's machine drying and peasant household's working ability are limited, therefore, same day harvesting A large amount of hemerocallis can not such as be dried in time, be lost huge.To solve the above problems, can be using barn or drying equipment to chrysanthemum Dish carries out extensive drying.But, surface green is carried out in barn or drying equipment to day lily after hemerocallis steam beating It can not completely be taken off in drying process, dry vegetalbe surface is in dirty-green, influence attractive in appearance, lose commodity value.Thus, day lily is dried Lifting of the preceding pretreatment chlorisis method to drying quality is significant.
The content of the invention
It is an object of the invention to solve barn drying day lily color and luster unsightly problem and provide a kind of day lily bake Preprocess method before room drying.The purpose of the present invention is reached by following measure:
(1)The first step, vacuum packaging, room temperature storage suppresses to bloom.
Take after boiling water cooling, add Natamycin thereto and kojic acid is configured to biological preservation liquid, Natamycin and kojic acid Mass percent concentration be respectively 0.02%~0.03%, 0.5%~0.6%.By the new hemerocallis of harvesting preparation biology Soaked 20~30 minutes in fresh-keeping liquid, pull out, vacuum sealed package is stored 1~2 day at ambient temperature, suppress to bloom.
(2)Second step, prepares chlorisis agent.
Take after boiling water cooling, Natamycin, kojic acid, 40% ethephon agent and jasmonic ketone methyl esters are added thereto and is prepared Chlorisis agent, Natamycin, kojic acid, the mass percent concentration of 40% ethephon agent be respectively 0.02%~0.03%, 0.5%~ 0.6%th, 0.05%~0.06%, the concentration of jasmonic ketone methyl esters is 10mg/L~15mg/L.
(3)3rd step, immersion.
, will be through step under room temperature condition(1)The day lily of processing is immersed in chlorisis agent 1~2 hour.
(4)4th step, chlorisis.
Through step(3)Day lily after immersion seals at ambient temperature, preserves 4~5 days, you can take off green, presents Yellow.
One preferred embodiment of such scheme is, the step(1)Middle vacuum sealed package is store in PVC plastic pocket Deposit.
Due to easily being bloomed at high temperature after day lily harvesting, thus the present invention suppression that takes measures first blooms, and uses Sealed storage, reduces oxygen concentration under vacuum, and reduction respiratory intensity reaches the purpose that suppression is bloomed.Further, since often New hemerocallis easily rots under the conditions of temperature, can reach using biological fresh-keeping method and suppresses the mesh that day lily rots 's.Natamycin can suppress the growth of the fungies such as mould, and kojic acid can suppress the growth of the microorganisms such as bacterium and polyphenol oxidase enzyme activity Property caused by brown stain, ethephon (CEPHA),2-(chloroethyl) phosphonic acid and jasmonic ketone methyl esters can promote day lily ripe, accelerate the degraded of chlorophyll, thus this hair It is bright to can reach using exogenous hormone processing day lily and take off green day lily is suppressed into Post flowering, the purpose of yellow is presented.
Compared with prior art, advantages of the present invention mainly has:(1)Under cryogenic conditions, using biological species food additives, Food-safety problem caused by chemical addition agent is avoided, meets the requirement of safety food processing;(2)The inventive method is simple, Workable, processing cost is low, is adapted to rural area peasant household and the application of little Wei enterprises.(3)Day lily is existed using the inventive method Pre-processed before drying, make the beautiful appearance of drying day lily, commodity value is significantly improved.
Embodiment
Embodiment 1:
After the cooling of 100kg boiling water, 27g Natamycins are added thereto and 550g kojic acids prepare biological preservation liquid.25kg is plucked New hemerocallis soaked 20~30 minutes in biological preservation liquid, pull out, pack in PVC plastic pocket, room temperature condition Lower storage 1~2 day.Again by after other 100kg boiling water cooling, 25g Natamycins, 550g kojic acids, 40% ethene are added thereto Sharp aqua 150g and 1.5g jasmonic ketone methyl esters is configured to chlorisis agent.Under room temperature condition, energy of blooming will be lost through aforementioned processing The day lily of power is immersed in chlorisis agent 1~2 hour, is then pulled out, is sealed in PVC plastic pocket, is preserved 2~3 days, is taken off green Color, is presented yellow.
