| 摘要： 近幾年鳳梨釋迦鮮果外銷量大增，農民獲利頗佳，但外銷國家98%集中在中國大陸，產業潛伏極大風險，急需拓展鳳梨釋迦果品之利用方式，以穩定鳳梨釋迦產業發展。本計畫之鳳梨釋迦採後催熟技術中，果實以益收生長素稀釋500倍全果浸泡、益收生長素原液塗抹果梗、電石處理8小時，及乙烯處理8小時等方式，皆可促進果實後熟；其中以益收生長素稀釋500倍後全果浸泡處理，可減少二分之一後熟時間，且果肉品質正常，適合供消費者食用或加工原料使用。鳳梨釋迦冷凍加工產品中，截切厚度會影響PPO酵素活性造成加工品褐變反應，其中截切厚度3cm成品於儲藏時間第2個月，褐變指數及白色度相較於其他截切厚度成品表現較佳。本計畫研發催熟技術及加工產品，可擴展鳳梨釋迦果品利用性，提升產業競爭力。The Annona fruit export volume was significant increased in recent years, farmers’ income was good. But 98% export concentrated in China, the Annona industry had great risk. It needs to development different use of fruit for stability industry. This project include ripening technique of atemoya postharvest, using 500-fold Ethrel of whole fruit, 1-fold Ethrel on fruit pedicle, Calcium carbide for 8 hours, and ethylene for 8 hours, etc., could accelerate to fruit ripe of atomoya. And using 500-fold Ethrel of whole fruit was best method to be reduced ripening time that had good fruit quality for consumption or processing materials use. In atemoya frozen processing products, thickness could affect browning reaction as the result of the PPO enzyme activity. Where there were better analytical results in browning index and whiteness in the thickness of 3cm slice when storage test was finished in the second month. The ripening technique of atemoya postharvest and processing technology development would increase the utilization of atemoya fruits and enhance industrial competitiveness. |
