Embodiment 1

[0018] A method for keeping carambola fresh is to first select the fresh carambola that is 7-8 mature after harvest, without mechanical damage, soak it in a calcium chloride solution with a concentration of 1% for 15 minutes, drain and place it in a 3% concentration Soak in the composite fresh-keeping solution for 3 minutes and dry the water; then spray the traditional Chinese medicine fresh-keeping agent, dry it, freeze at 10°C for 2h, then put it into a polyvinyl chloride fresh-keeping film with a thickness of 0.07mm, and then tie the fresh-keeping film. Put it in the outer packing box, store or sell at room temperature;

[0019] The compound fresh-keeping solution is a mixture of 0.2% vitamin C solution and 3.5% chitosan aqueous solution at a volume ratio of 0.5:1, and the traditional Chinese medicine fresh-keeping agent includes: 10 parts of Stemona, 15 parts of fennel, garlic 3 parts, 12 parts of galangal, 8 parts of sage, 20 parts of sage grass, 9 parts of forsythia, 5 part...

Embodiment 2

[0022] One way to keep carambola fresh is to select fresh carambola that is 7-8 mature after harvest and without mechanical damage, soak it in a calcium chloride solution with a concentration of 5% for 5 minutes, drain and place it at a concentration of 0.5 % Composite fresh-keeping solution is immersed for 10 minutes, and the water is dried; then spray the traditional Chinese medicine fresh-keeping agent, dry, freeze at 4℃ for 0.5h, then put it into a polyvinyl chloride fresh-keeping film with a thickness of 0.0457mm, and then put the fresh-keeping film Tie the mouth, put it in the outer packing box, store or sell at 5~10℃;

[0023] The compound fresh-keeping liquid is a mixture of 3% vitamin C solution and 0.8% chitosan aqueous solution in a volume ratio of 0.5:1, and the traditional Chinese medicine fresh-keeping agent includes: 18 parts of Stemona, 7 parts of fennel, garlic 10 parts, 5 parts of galangal, 15 parts of sage, 10 parts of sage grass, 18 parts of forsythia, 10 part...

Embodiment 3

[0026] One way to keep carambola fresh is as follows: it first selects fresh carambola that is 7-8 mature after harvest and has no mechanical damage, soaks it in a calcium chloride solution with a concentration of 3% for 10 minutes, drains and places it at a concentration of 2 % Compound fresh-keeping solution is immersed for 7 minutes, and the water is dried; then spray the traditional Chinese medicine fresh-keeping agent, dry, freeze at 8℃ for 1h, then put it into a PVC fresh-keeping film with a thickness of 0.05mm, and then tie the fresh-keeping film 口, put in the outer packing box, store or sell at room temperature; among them

[0027] The composite fresh-keeping liquid is a mixture of 2% vitamin C solution and 2.1% chitosan aqueous solution in a volume ratio of 1:1, and the traditional Chinese medicine fresh-keeping agent includes: 15 parts of fennel, 10 parts of garlic and garlic 7 parts, 8 parts galangal, 12 parts sage, 15 parts Xihuangcao, 12 parts Forsythia, 8 parts cinna...

Abstract

The invention discloses a fresh-keeping method of carambolas, which comprises the following steps: selecting picked fresh carambolas which are ripe to the 70-80% degree and have no mechanical damage, soaking the carambolas in a calcium chloride solution with a concentration of 1-5% for 5-15 min, draining, then soaking in a composite fresh-keeping solution with a concentration of 0.5-3% for 3-10 min, airing to remove moisture; then spraying a traditional Chinese medicine fresh-keeping agent, airing, freezing at 4-10 DEG C for 0.5-2 hours, filling into a fresh-keeping film, tying the fresh-keeping film, putting into an external packing case, and storing or selling at room temperature or 5-10 DEG C. The calcium chloride, chitosan, vitamin C and the traditional Chinese medicine fresh-keeping agent adopted by the method of the invention are all safe and healthy fresh-keeping agents, have significant fresh-keeping effect; the method can well prolong the fresh-keeping and storage time of carambolas, and facilitates popularization.

Description

Technical field [0001] The invention relates to a fruit preservation technology, in particular to a method for carambola preservation. Background technique [0002] Carambola (Averrhoa Ccaambola L.) is a tropical evergreen fruit tree. The mature fruit is sweet and sour, juicy and rich in vitamin C. It has the effects of dispelling wind, promoting body fluid, quenching thirst, stopping bleeding, pulling poison and promoting muscle growth. It is one of the characteristic fruits of South my country . However, due to the thin, brittle, prismatic, and easy-to-damage skin of the carambola fruit, it brings difficulties in post-harvest handling and shortens the storage time of the carambola, which is not conducive to the fresh sale and export of the carambola. [0003] At present, the preservation of carambola is mainly low-temperature atmosphere preservation, film preservation and chemical preservation. Among them, film preservation refers to applying a film preservative to the surface of...
