Embodiment 1

[0016] Take a batch of Tainong awns that have just been picked from the orchard, wash and dry the skin stains and spilled juice, and then spray a compound preservative containing the following components:

[0017] Shellac: 5%

[0018] Three-dimensional network porous silica: 0.5%

[0019] NaOH: 0.4%

[0020] Spock: 0.05%

[0021] Sodium dodecylbenzenesulfonate: 0.02%

[0022] water: balance

[0023] Stored at room temperature (25°C), the decay rate of Tainong mango sprayed with preservatives is less than 1% after 10 days of storage, and less than 5% after 25 days of storage, the weight loss rate is doubled, and it can still maintain a fresh taste .

Embodiment 2

[0025] Take a batch of ivory awns just picked from the orchard, wash and dry the skin stains and overflowing juice, and then spray the compound preservative containing the following components:

[0026] Shellac: 7%

[0027] Diatomaceous earth: 1%

[0028] K 2 CO 3 : 0.6%

[0029] Tekoto: 0.1%

[0030] Tween 80: 0.06%

[0031] Water: balance.

[0032] Stored in a refrigerator at 12°C and a relative humidity of 60%, the rot rate of the ivory awn sprayed with preservatives is less than 1% after 25 days of storage, and less than 3% after 40 days of storage, the weight loss rate is reduced by 1 times, and it can still be preserved. Fresh palate.

Embodiment 3

[0034] Take a batch of pineapples just picked from the orchard, wash and dry the skin stains and overflowing juice, and then spray the compound preservative containing the following components:

[0035] Shellac: 9%

[0036] Porous ceramics: 2%

[0037] NaHCO 3 : 0.8%

[0038] Promethine: 0.2%

[0039] Tween 80: 0.1%

[0040] Water: balance.

[0041] Stored in a refrigerator at 8°C and a relative humidity of 60%, the rot rate of pineapple sprayed with preservatives is less than 2% after 15 days of storage, and less than 5% after 25 days of storage, the weight loss rate is reduced by 1 times, and it can still keep fresh taste.

Abstract

The invention discloses a porous material composite fruit wax-coating preservative capable of controlling breath, and solves the problems that fruits are rotted and deteriorated easily to produce alcohol, can be kept fresh difficultly and cannot be stored. The composite preservative consists of the following components in percentage by mass of 5 to 9.8 percent of shell-lac, 0.05 to 3 percent of porous material (comprising three-dimensional network porous silicon oxide, kieselguhr, porous ceramic and porous carbon), 0.04 to 3 percent of cosolvent, 0.05 to 0.3 percent of bacteriacide, 0.01 to 0.1 percent of dispersing agent and the balance being water. Mangos and pineapples which are coated with the preservative can still taste fresh after being stored for 30 days, so that the weight loss rate is reduced twice, and the rotting rate is less than 5 percent; and the quality of fruits is guaranteed, the storage period and the shelf life of the fruits are prolonged, and economic loss caused by rotting and deterioration of the fruits and the like is reduced effectively.

Description

technical field [0001] The present invention relates to a fruit fresh-keeping product in the field of food engineering technology, to be precise, a controllable breathing porous material composite fruit wax coating film preservative, which is mainly used for mango, pineapple, banana, lychee, grape, apple, longan , Strawberries, citrus, pears and other fruits, especially for tropical fruits with high respiratory intensity. Background technique [0002] The production of tropical fruits in my country is very rich, such as mango, pineapple, banana, lychee, etc., and the ripening period is mostly in high temperature and high humidity seasons. Poor conditions and technology have caused great losses to fruit farmers and seriously affected the economic benefits of fruit growing areas. Postharvest fruit storage technology has become a bottleneck in the development of tropical fruits in my country. Although the fruit coating preservatives commonly used in the market slow down the ro...
