Mix together；
Step 5, the day lily antistaling agent of the day lily of naturally dry and claim 1 is fitted into freshness protection package, carried out cold
Hide, refrigerated storage temperature is 1~3 DEG C.
The beneficial effects of the present invention are：Preservation method provided by the invention can realize dual fresh-keeping, be konjaku first
Fresh-keeping solution made of fine powder and granatum extract solution with antioxidation soaks day lily, forms day lily surface
One layer of antibacterial film, can effectively prevent O2Into inside day lily, bacteria attack is prevented, extends period of storage, is played fresh-keeping anti-
The effect of bacterium, after be put into day lily antistaling agent, carry out that the second weight is fresh-keeping, garlic has very strong antibacterial to various bacteria and fungi
Ability, it is inhibited to the growth and breeding of microorganism, fresh-keeping, safe and non-toxic, Huang is carried out to day lily using its antibiotic property
Berberine in coptis extract has significant bacteriostasis, and forsythia suspense extraction has very strong antibacterial action, has been largely used to
The antistaling agent of food, sodium benzoate and citric acid have antiseptic effect, and mixed liquor is attached on food starch, do not influence chrysanthemum
The original quality of dish, beneficial to the long-period freshness preserving of day lily, the antistaling agent is naturally pollution-free, and fresh-keeping effect is strong, is carried using the present invention
The preservation method of confession, day lily can be fresh-keeping 12 months, and color cadmium yellow, have the due delicate fragrance of day lily, eat tender and crisp tasty and refreshing.
Embodiment
To describe the technology contents of the present invention, the objects and the effects in detail, it is explained below in conjunction with embodiment.
The design of most critical of the present invention is:Dual fresh-keeping is carried out to day lily, is first konjaku powder and there is antioxygen
Fresh-keeping solution made of the granatum extract solution of change effect soaks day lily, after be put into day lily antistaling agent, extend day lily
Fresh keeping time.
The present invention provides a kind of day lily antistaling agent, including following raw material is prepared：30~50 parts of galangal, garlic 40
~55 parts, 40~50 parts of food starch, 15~21 parts of coptis extract, 13~17 parts of forsythia suspense extraction, 4~9 parts of sodium benzoate
With 3~5 parts of citric acid.
The present invention also provides a kind of day lily preservation method using above-mentioned day lily antistaling agent, comprises the following steps：
Step 1, by day lily under conditions of 70~95 DEG C 40~60s of blanching；
