Abstract
Nontoxic antistaling agent of a kind of citrus and citrus fresh-keeping method, it is that 1%-10% calcium hydroxide aqueous solution soaks fruit that the citrus that need are stored is put into concentration, drying the back hides with the plastic bag packaging envelope, citrus was stored five months, keep former fruit color and luster, local flavor, prevent to rot, and have nontoxic, inexpensive and method characteristic of simple.
Description
The present invention is nontoxic antistaling agent of a kind of citrus and citrus fresh-keeping method.
China abounds with raciness such as the close tangerine in Wenzhou, Pon mandarin orange, local morning, nutritious loose-skin orange, and loose-skinned oranges rots and the dehydration drying shrinkage easily, and fresh fruit supply time weak point does not satisfy consumer wants.The present fresh-keeping method of citrus has multiple, and common method is to soak fruit or be coated with fruit with fruit wax with soup after plucking citrus.Soak the fruit soup and contain harmful composition more, as publication number is a kind of fresh-preserving agent for oranges and tangerines of the Chinese invention patent bulletin release of CN87102017A, include carbendazim class anti-corrosion agent, carbendazim is a systemic fungicide, higher mammal toxicity is belonged to low toxicity, and and for example publication number is the natural fresh-keeping agent of fruits that the Chinese invention patent bulletin of CN1041262A is released, will be with the 2.4-D point base of a fruit in implementation process, 2.4-D absorption growth hormone in belonging to belongs to moderate toxicity to higher mammal toxicity.Pericarp after above-mentioned antisepsis antistaling agent is handled is residual hazard more or less, and the consumer has certain scruples, and tangerine peel has also lost the value of being used as medicine and refining the comprehensive utilization of tangerine wet goods.
The objective of the invention is to provide a kind of good refreshing effect, fresh-preserving agent for oranges and tangerines and preservation method nontoxic, with low cost.
The present invention is nontoxic antistaling agent of a kind of citrus and citrus fresh-keeping method, it is characterized in that to dissolve into concentration be the solution of 1%-10% and be used for citrus and soak fruit with water and calcium hydroxide, dries after soaking fruit, hides with plastic bag packaging envelope then.
Calcium hydroxide can be made edible additive, except making concentrated edible agent and PH conditioning agent, also can be used for pharmacy and demineralized water etc., and is nontoxic to human body.
Principle of the present invention is as follows:
1, the used antistaling agent calcium hydroxide aqueous solution pH value of the present invention is between 12-13, and pathogen can not live in such strong basicity environment, and citrus soaks the fruit back initial stage with antistaling agent and just killed the germ of fruit surface.
2, fruit dries rear surface formation one deck tunicle, to mainly causing rotten germ (Penicillium notatum, green mold bacterium, the rotten bacterium of the base of a fruit etc.) good inhibition effect is arranged.
3, fruit is put into after the polybag, and the calcium hydroxide on surface can absorb carbon dioxide in air, has played the gas regulation effect, has delayed the aging of fruit, has strengthened the resistance against diseases of fruit.
The fresh-keeping test examples of citrus unshiu Marcovitch:
To adopt down near ripe citrus unshiu Marcovitch fruit, be that this antistaling agent solution of 2% is soaked fruit with concentration in 3 days, drying the back packs with the polybag single fruit, adorn in the carton for per then 20 jin-30 jin, check after five months in (4 ℃-19 ℃ of per day room temperatures) storage under the common house owed by a citizen normal temperature condition in Wuhan City: the fruit profile is full, color and luster is vivid, good fruit rate 95%, bright base of a fruit rate 100%.Through quality determination, soluble solid content 15.5%, total acid 1.376%, Gu acid ratio 11.26, Vit C contents is 21.2706 milligrams in per 100 gram fruit juice, mouthful gustation is dense, sweet acid appropriateness, local flavor is normal.
Contrast test:
Soak fruit with 250PPm2.4-D and 500PPm carbendazim mixed liquor, with aforementioned same method and same time storage, good fruit rate 83%, bright base of a fruit rate 50%, soluble solid content 12.6%, total acid 1.257%, Gu acid is than 10.02, Vit C contents is 18.7759 milligrams in per 100 gram fruit juice, acid.
Claims (2)
1, the nontoxic antistaling agent of a kind of citrus, it is characterized in that with water and calcium hydroxide dissolve into concentration be the solution of 1%-10% and be used for citrus soak the fruit.
2, a kind of citrus fresh-keeping method is characterized in that with citrus concentration being to dry after the calcium hydroxide aqueous solution of 1%-10% soaks fruit, hides with the plastic bag packaging envelope then.
