CN105309599A - Preserving method for asparagus - Google Patents

Abstract

The invention discloses a preserving method for asparagus. The method comprises the following specific steps that the pest-free asparagus is selected, short asparagus roots which are 12-16 cm are shorn and kept, and clean water is used for cleaning away soil on the surfaces of the short roots completely; salt is placed into water and stirred uniformly to prepare a salt solution with the concentration of 4-6%; the salt solution is heated to 45 DEG C-55 DEG C, then the short asparagus roots are placed into the salt solution to be scalded for 40-60 seconds, and after being bailed out, the short asparagus roots are cooled to 20 DEG C-25 DEG C; the short asparagus roots are stored in a refrigerator, and the temperature in the refrigerator is controlled to be 3 DEG C-5 DEG C. The preserving method has the advantages of being good in asparagus storage effect and the like.

Description

The store method of a kind of asparagus

Technical field

The present invention specifically relates to the store method of a kind of asparagus, is applied to asparagus technical field of memory.

Background technology

Asparagus is one of large famous dish in the world ten, have another name called asparagus, enjoy the laudatory title of " kings of vegetables " in the international market, asparagus is rich in several amino acids, protein and vitamin, its content is all higher than general fruits and vegetables, asparagine particularly in asparagus and trace elements of selenium, molybdenum, chromium, manganese etc., there is adjustment organism metabolism, improve effect of body immunity, in the prevention and therapy to hypertension, heart disease, leukaemia, leukemia, oedema, cystitis etc., there is very strong inhibitory action and pharmacodynamics effect.

Asparagus is after harvesting, and the freshness of asparagus can reduce very soon, organizing of asparagus so not only can be caused hardening, and can lose a large amount of nutrition, therefore, needs to provide a kind of method for storing asparagus.

Summary of the invention

For solving the defect of prior art, the invention discloses the store method of the good asparagus of a kind of asparagus preservation effect.

The invention discloses the store method of a kind of asparagus, concrete steps are as follows:

Step one: select the asparagus without insect pest, cut short of the asparagus reserving 12-16 ㎝, uses clear water to be cleaned up by the earth in short root table face;

Step 2: put into by salt in water, after stirring, configures the salt solution that concentration is 4%-6%;

Step 3: saline solution is heated to 45 DEG C-55 DEG C, then puts into short for asparagus in saline solution and scalds 40-60 second, then after pulling out short for asparagus, be cooled to 20 DEG C-25 DEG C;

Step 4: be stored in refrigerating chamber by short for asparagus, the temperature in refrigerating chamber controls at 3 DEG C-5 DEG C.

The store method operation of asparagus of the present invention is more convenient, and the holding time of asparagus is long, and short of asparagus is not perishable, and the nutrition of short of asparagus is also not easily run off, and the preservation effect of asparagus is good.
