Description
Technical field
The present invention relates to a kind of preservation method of medlar fresh fruit.
Background technology
Lycium barbarum (Lycium barbarumL.) is the most characteristic local speciality in Ningxia, and lycium barbarum becomes the distinguishing products with Regional mark.The natural conditions of Ningxia uniqueness make the lycium barbarum fruit have the congenital monopoly powers such as skin is thin, meat is thick, sugar content is high, lycium barbarum production on quantity and quality all in national top standard.Matrimony vine has become Ningxia advantage leading industry, and the Ningxia agricultural development is played a supporting role, and its industrial advantage status is obvious.
" seed selection of No. 6 ”Shi Ningxia limited companies of forestry research institute of peaceful Qi eat the matrimony vine new varieties raw; there is the obvious advantages such as output is high, the fruit grain is large, pulp is thick, few containing the seed amount, nutrient composition content is high, the sweet free from extraneous odour of taste; suitable eating raw; and having passed through the identification that the Ningxia high quality tree species is authorized and national new variety of plant is protected, first eats the matrimony vine new varieties raw to be confirmed as Ningxia.Compare mass of 1000 kernel with the lycium barbarum main breed and output all has very large advantage.
Lycium barbarum is China's tradition rare medicinal herbs, and the title of " red treasured " is arranged, and is subject to for a long time China and foreign countries' medical circle and dietotherapy expert's great attention as the integration of drinking and medicinal herbs fruit.Research shows, lycium barbarum contains active ingredient and several amino acids and the trace elements such as LBP-X, betaine, hyoscine, thiamine, riboflavin, sterol, cinnamoylhistamine, rutin sophorin and folium lycii albumen.
But the fresh-keeping of medlar fresh fruit is always a great difficult problem.
Summary of the invention
The preservation method that the purpose of this invention is to provide a kind of safe, economic medlar fresh fruit, can make medlar fresh fruit extend storage time under the prerequisite that keeps nutritional labeling and quality.
A kind of preservation method of medlar fresh fruit, its special feature is, comprises the steps:
(1) get medlar fresh fruit, water cleans will really show the foreign material removal, then drain after second with 0.5-1.0mg/L ozone solution immersion 30-40, with pure water, clean afterwards, after draining, surface water be dried up, and the Freshness keeping disc of packing into is stand-by;
(2) medlar fresh fruit after step (1) is processed, every 5-8kg freshness protection package of packing into, unlimited sack is put into pre-freezer precooling, after making the core temperature reach 0-1 ℃, put into antistaling agent one bag No. 1 in freshness protection package, No. 2 antistaling agents one bag, then the freezer of put into-2--1 ℃ refrigerates to tighten sack.
What wherein medlar fresh fruit adopted Zhongning County, Ningxia or Yinchuan City eats matrimony vine " No. 6, peaceful Qi " fresh fruit raw.
Wherein No. 1 antistaling agent is efficient ethene remover, and No. 2 antistaling agents are SO
2Slow-release preservative.
Really show manual harvesting of complete red time band carpopodium at medlar fresh fruit in step (1), and select wherein mass of 1000 kernel more than 1200g, bright in colour, with carpopodium, without the fruit of disease and pest.
The invention provides a kind of preservation method of medlar fresh fruit, this technique comprise manual pluck that band carpopodium lycium barbarum fresh fruit, cleaning (surface disinfection), fruit table dry up, sabot, precooling, antistaling agent are processed, refrigeration, make the lycium barbarum fresh fruit can keep original color, freshness date can reach 80 days-90 days, can keep medlar fresh fruit well the fruit rate more than 90%.Fresh-keeping through the inventive method to eat matrimony vine raw direct-edible, and antistaling agent is ethene adsorbent and slowly-releasing SO
2Antistaling agent.Process costs of the present invention is low, easy and simple to handle, and technical application has extended the lycium barbarum antistaling fresh cycle.
