Embodiment 1

[0018] The preparation technology of antistaling agent: 1) the optimization of extraction technology takes the content of total volatile oil of compound antistaling agent and the content of galangin as investigation index, adopts the optimal extraction process of orthogonal experiment screening compound antistaling agent, makes extraction with water Solvent, extraction time (150, 120, 90; 120, 90, 60; 90, 60, 30 / min), extraction times (1, 2, 3 / time) and solvent multiple (6, 8, 10 / time) were set up 3 The optimal extraction process was selected as follows: the number of extractions was 3 times, the extraction time was 150min, 120min, 90min, and the solvent multiple was 6 times. Under the extraction process, the total volatile oil content of the compound preservative is 1.2%, and the galangin content is 0.87 mg / g.

[0019] 2) Screening of the optimal ratio: The rot rate and weight loss rate of papaya is used as the investigation index, and the optimal ratio of compound preservati...

Embodiment 2

[0026] 1) Extraction of compound antistaling agent: Weigh 2000g of galangal, 500g of nutmeg, 700g of Huoxiang, and 600g of Zanthoxylum bungeanum; add 6 times the amount of water, reflux and extract for 5 hours, extract the volatile oil to obtain 31mL of volatile oil, and then add 8 times the amount of Water extracted twice, filtered, combined filtrates, concentrated under reduced pressure to extract 415g.

[0027] 2) Prepare compound fresh-keeping granules, add 31mL of volatile oil to dissolve in 10 times the amount of ethanol, add to the water saturated solution of 10 times the amount of β-cyclodextrin, and stir on a magnetic stirrer while adding, at 40°C Inclusion for 60 minutes, refrigerated in the refrigerator for 24 hours, suction filtered, washed with a small amount of water, pumped until almost dry, washed 4 times with petroleum ether, dried at 40°C for 5 hours, and obtained. Add 1.5 times the amount of soluble starch and dextrin to 415g of medicinal liquid extract, mix...

Embodiment 3

[0031] Effects of galangal single herb extract on papaya stored at room temperature

[0032] 1) Extraction of antistaling agent Take galangal 500g, add 6 times the amount of water to extract for 5 hours, extract the volatile oil, add 8 times the amount of water to extract twice, filter the galangal decoction, and dissolve the volatile oil in Tween 80 The galangal preservative is obtained in the water decoction.

[0033] 2) Use of antistaling agent Gained galangal antistaling agent is formulated into 80g / L, 60g / L and 40g / L respectively, and the papaya is rinsed, and the rot rate is counted after 10 days of storage in an open environment at room temperature, and the treatment group is 80g / L Compared with the blank group, the rot rate is lower, but compared with the compound preservative, it can not significantly prolong the storage time at room temperature. The rot rate of the galanga single preservative treatment group has reached 75% after 10 days of storage. And under the sa...

Abstract

The invention relates to a fruit fresh keeping agent, and a preparation method and an application thereof, especially relates to a papaya fresh keeping agent, and a preparation method and an application thereof, and belongs to the technical field of foods. The papaya fresh keeping agent comprises Rhizoma Alpiniae Officinarum, Myristica fragrans, wrinkled gianthyssop and Chinese prickly ash according to a certain mass ratio. The papaya fresh keeping agent developed on the basis of medicinal and eatable plants has a substantial fresh keeping effect, and can effectively prolong the fresh keeping time of papaya and maintain the flavor and color of papaya. The medicinal and eatable plants are selected as raw materials, so the fresh keeping agent has high safety; and the traditional Chinese medicine and pharmacy compatibility theory is referenced, and antibiosis and anti-oxidation activity synergy among Chinese herbal medicinal components is used, so the antibiosis effect is improved, the antibiosis concentration is reduced, the antibiosis spectrum is broad, the anti-oxidation intensity of the fresh keeping agent is enhanced, oxidation of vitamins and other nutritional components is prevented, and no destroy of nutrition of fruits is maintained.

Description

technical field [0001] The invention relates to a fruit preservative, its preparation method and application, in particular to a papaya preservative, its preparation method and application, and belongs to the technical field of food. Background technique [0002] Fruits are rich in vitamins, organic acids, and minerals, and are important dietary supplements for humans. Among them, papaya has unique flavor and rich nutrition, and occupies an important position in the fruit market at home and abroad. However, papaya is affected by high temperature and high humidity climate conditions in the place of production. After harvesting, papaya has strong respiratory metabolism and is prone to browning and rot, which brings great difficulties to storage, transportation and preservation. Therefore, it is imperative to develop a natural, efficient, cheap, non-toxic, and residue-free papaya preservative. The most effective way to keep papaya fresh after picking is cold storage combined ...
