(46(3):278-293)Studies on Export Suitability of Different Carambola Cultivars

本研究之目的在探討不同品種甜楊桃於模擬外銷貯運作業流程下之品質變化，並評估其外銷適性與潛力。試驗結果顯示五種甜楊桃經低溫檢疫模擬外銷貯運作業流程後，糖度、可滴定酸及硬度等均有下降的趨勢，pH 值會升高，失重均低於2 %，低溫可抑制各品種楊桃之黃化現象。經最後之官能品評及整體評估認為以秤錘種、青墘種在低溫檢疫模擬外銷貯運後仍可維持較佳的品質並有較高的商品可售率（秤錘種約100％及青墘種83％以上），故最適合外銷，二林種次之，楊桃臺農一號及馬來西亞種則因有將近30％之擦壓傷及約有100％之果實發生寒害而不適合外銷。The purposes of these studies were to investigate the changes of fruit qualities of five carambola cultivars during simulated export storage procedure and to estimate the export suitability and potentiality. The results showed that the sugar content, titratable acidity and firmness of the five tested cultivars declined during simulated exportation. However, the pH value of each cultivars incressed. All the five cultivars showed different degrees of yellowing but the weight loss decreased less than 2%. It was suggested that “Cheng Chwei” and “Ching Chyan” were the most suitable for exportation than other cultivars because of their better qualities and higher salability (Cheng Chwei nearly 100% and Ching Chyan above 83%) after simulated exportation. “Er Lin” was second one suitable for exportation. “Tainoung No.1” and “Malaysia” were not suitable for exportation due to high mechanical injury (30%) and chilling injury (100%) after simulated exportation
