However, "Golden Bergamot" is difficult to buy in the market after the Spring Festival; at the same time, due to the freshness of "Golden Bergamot" during transportation and storage, its main market is limited to the Jinhua area

The existing fresh-keeping methods for bergamot fruit include low-temperature refrigeration and chemical substance spraying. The low-temperature preservation method has the disadvantages of high investment, strict technical requirements, relatively large energy consumption, and does not meet the requirements of "energy saving and emission reduction". Industrial development, farmers' income increase and social and economic sustainable development are all unfavorable

The chemical substance spraying method does not meet the green environmental protection requirements due to the potential pollution in the spraying process.
