It is well-adapted to Taiwan’s climate and has strong growth potential and good adaptability. It is cultivated throughout the country, including Hualien County, Taitung County, Yilan County, Yunlin County, Chiayi County, Nantou County, Tainan County, Miaoli County, New Taipei City and other regions. It is usually used as a fruit for the Mid-Autumn Festival. Farmers usually use the "white dew" solar term as the harvest index day. Therefore, the fruit harvest period is concentrated in the few days before and after the white dew for the Mid-Autumn Festival. On the other hand, due to differences in climatic environment and cultivation methods in different regions, the maturity period is not consistent. The areas with lower temperatures and shorter sunshine hours usually take longer to develop. If they cannot be supplied before the Mid-Autumn Festival, it may cause slow sales. As a result, some farmers often harvest early, resulting in uneven fruit quality on the market. Due to the above-mentioned production characteristics, the Wendan pomelo industry is very prone to problems such as imbalance between production and sales and uneven quality. It is urgent to develop techniques for digesting excess or poor quality fruits. Citrus fruit peel is rich in essential oils, and has toxic effects on microorganisms and insects. It is a natural fungicide and has the potential to develop postharvest treatment technologies for horticultural products such as edible coating ingredients. This project intends to establish the production technology of the edible coating using Wendan pomelo peel extract and preliminarily evaluate its antibacterial effect to facilitate the future development of the postharvest treatment and preservation technology of the garden products, and to solve the problems of the imbalance between the production and sales of Wendan pomelo and the uneven quality.文旦柚萃取物可食性膜採後處理pomelo extractedible coatingpostharvest
