Problems solved by technology

But, the fresh-keeping technology about bergamot fruit is still very scarce at present, and there is seldom the report in this respect both at home and abroad
Shentu Wenyue, School of Biology, Zhejiang University, etc. used "4‰ Gradite + 14‰ Carbendazim" or "4‰ Gradite + 14‰ Carbendazim + 10mg / L2, 4-D+10mg / L6-BA ” or “4‰ Gramite + 14‰ Carbendazim + 20mg / L2, 4-D + 20mg / L6-BA” or “4‰ Gramite + 14‰ Carbendazim + 20mg / L2, 4-D +20mg / L6-BA+20mg / LCaCl 2 "After the soaking treatment, put it in a fresh-keeping bag for storage. It is found that the mite removal treatment and the bactericidal treatment of plant growth regulators can effectively improve the fresh-keeping effect, but if the fresh-keeping bag is not used, the water loss is still relatively serious.
There are many successful cases in the study of chitosan’s fresh-keeping application, but there are also reports that the fresh-keeping effect is not obvious. For example, Zhu Ying from Northwest Agriculture and Forestry University used 1% chitosan to treat chayote, combined with PE fresh-keeping bags, and stored in different places. The fresh-keeping effect was evaluated at high temperature, and the results showed that chitosan coating treatment had no obvious effect on the fresh-keeping of chayote
We believe that, first of all, there is an essential difference between chayote and chayote fruit. The former is a perennial climbing herb of the Cucurbitaceae chayote family. The Latin name is Sechium edule (Jαcq.). And bergamot is a non-climate fruit; secondly, the composition of chitosan preservative used in the research is too simple

Embodiment 1

[0035] Fruit material: Jinhua Bergamot (smaller fruit shape).

[0036] Select bergamot fruits that do not contain pathogenic bacteria and have no mechanical damage, soak them in agent A diluted 20 times for 10 minutes, rinse them with clean tap water 2-3 times, remove the residual disinfectant on the surface of fruits and vegetables, and then place the fruits in a ventilated place to dry naturally. Soak the whole bergamot in the 15 times diluted agent B for 3 minutes, completely submerged. After being dried at room temperature and protected from light, the fruit is directly stored in a cardboard box at room temperature or at low temperature, or is directly packed in various packaging boxes according to the requirements of the finished product, and is transported and sold directly.

[0037] Results: Compared with the non-treatment group, the storage period was prolonged by 50-66.67%, the rot rate was reduced by 62.48-80.38%, and the preservation effect was obvious.

Embodiment 2

[0039] Fruit material: Guangdong Bergamot (larger fruit shape).

[0040] Select bergamot fruits that do not contain pathogenic bacteria and have no mechanical damage, soak them in agent A diluted 10 times for 15 minutes, rinse them with clean tap water 2-3 times, remove the residual disinfectant on the surface of fruits and vegetables, and then place the fruits in a ventilated place to dry naturally. Soak the whole bergamot in the 10 times diluted agent B for 5 minutes, completely submerged. After being dried at room temperature and protected from light, the fruit is directly stored in a cardboard box at room temperature or at low temperature, or is directly packed in various packaging boxes according to the requirements of the finished product, and is transported and sold directly.

[0041] Results: Compared with the non-treatment group, the storage period was prolonged by 45.29-60.70%, the decay rate was reduced by 49.56-68.77%, and the preservation effect was obvious.

Abstract

The invention provides a citrus medica var sarcodactylis fruit antistaling agent and an application method thereof, which belong to the technical field of preservation and storage of fruits and vegetables. The method can be widely used to solve the problems of preservation and storage of each variety of citrus medica var sarcodactylis. The antistaling agent consists of an A agent (a mixed disinfecting stock solution which mainly comprises propargite, carbendazol, sodium hypochlorite and the like) and a B agent (a preservative coating stock solution which mainly comprises chitosan, glutathionevitamin C, calcium chloride, glycerol and the like.). The method comprises the following steps: (1) immersing the A agent after diluting; (2) washing and drying; (3) immersing (spraying) the B agent after diluting; (4) drying; and (5) packaging. The method has the advantages of obvious preservation effect, wide application range, simple operation, high efficiency, green and environmental protection and low operating cost. Through treatment of the method, storage period of the citrus medica var sarcodactylis fruit can be prolonged by about 45 to 66 percent, rotting rate of the fruit can be reduced by about 49 to 81 percent, and the fruit can maintain plump appearance, bright color and rich fragrance after storage is finished.
