Problems solved by technology

In the prior art, post-harvest bananas are generally treated with chemical preservatives, which have a more obvious fresh-keeping effect, but there are chemical substance residues, drug resistance and environmental protection problems, which are not conducive to their health after consumers eat them. For example, the application number It is a Chinese invention patent of 201110280537.4; with people's pursuit of health and environmental protection, new banana fresh-keeping technologies have also appeared in recent years. Process the bananas and store them in an environment of 13-25°C
This method is simple, does not add any chemical substances, and is healthy and environmentally friendly. However, soaking bananas in hot water will stimulate and accelerate the respiration of bananas, destroy nutrients, and the bactericidal effect is not obvious, causing browning of the pericarp. This method has no fresh-keeping effect. Ideal, short fresh-keeping time, especially unfavorable for long-distance storage and transportation of bananas exported to foreign countries

Embodiment 1

[0021] A method for storing, transporting and keeping fresh bananas is as follows: after the Pubei Brazilian bananas with a maturity of 70% are harvested without mechanical damage, they are combed and cleaned in time to remove banana milk, dirt and residual flowers, and remove diseases, comb-shaped Untidy banana fruit is then put into a pool of chlorine dioxide with a concentration of 8mg / kg for sterilization and cleaning. In the present embodiment, low-pressure circulating spraying is used for cleaning, and the number of cleanings is 2 times; then the bananas after cleaning and draining are put into a concentration of 0.5% Chinese herbal medicine extract and soaked for 3-8 minutes, pulled out, and dried; The dried bananas are packed with activated clay and slaked lime film, then packed into packing boxes or boxes, and labeled; finally, the packed bananas are sent to a low-temperature storehouse at 13°C for pre-cooling for 24 hours, so that After the internal and external temp...

Embodiment 2

[0027] A method for storage, transportation and preservation of bananas is as follows: after the Pubei Williams bananas with a maturity of 70% are harvested without mechanical damage, they are combed and cleaned in time to remove banana milk, dirt and residual flowers, and remove diseases, combs, etc. Irregularly shaped banana fruits are then put into a pool of chlorine dioxide with a concentration of 8mg / kg for sterilization and cleaning. In the present embodiment, low-pressure circulating spraying is adopted to clean, and the number of times of cleaning is 2 times; then the bananas after cleaning and draining are put into a concentration of 0.5% Chinese herbal medicine extract and soaked for 5 minutes, pulled out, and dried; The final bananas are packed with activated clay and slaked lime film, then packed into packing boxes or boxes, and labeled; finally, the packed bananas are sent to a low-temperature storage at 13°C for 24 hours of pre-cooling, so that the inside and outs...

Abstract

The invention discloses a banana storage and transportation preservation method which comprises the following steps of: harvesting bananas, carrying out preservative and fresh-keeping treatment, pasting brands, packaging, precooling, storing and the like, namely, sterilizing and washing the bananas with the mature degree being 70-85% and without mechanical damage by using a 5-10mg / kg chlorine dioxide solution, subsequently putting the washed and drained bananas into a Chinese medicine herb extract solution with the concentration being 0.2-0.5% to be soaked for 3-8 minutes so as to carry out the preservative and fresh-keeping treatment; and pasting the brands, packaging and finally precooling and storing. According to the method, chlorine dioxide is used as a sterilizing agent, and the Chinese medicine herb extract solution is applied to the preservative and fresh-keeping treatment, so that the bananas are green, environment-friendly, free of chemical residue, good in preservation effect, long in preservation and freshness time, and applicable to long-distance storage and transportation when being exported and sold to other countries, and the method is easy to popularize.

Description

technical field [0001] The invention belongs to the field of fruit preservation, and in particular relates to a storage and transportation preservation method for bananas. Background technique [0002] Banana is one of tropical and subtropical famous fruits. Its yield is high, the pulp is sweet and smooth, rich in nutrients, and is deeply loved by people. It is a fresh fruit that is supplied all year round in domestic and foreign markets. my country's Guangdong, Guangxi, Hainan, Taiwan, Fujian, etc. all have production, especially the cultivation of bananas in Hainan, Taiwan, Guangdong and other places has become a major agricultural economy.
