中文摘要 | 為了瞭解包裝材料及貯藏溫度對金針鮮蕾品質之影響,以提供金針鮮蕾貯運參考,本試驗以OPS盒(CK)及低密度聚乙烯塑膠袋(LDPE袋)兩種材料密封包裝金針鮮蕾,每個包裝150g,分別置於5℃、10℃、15℃冷藏庫及不控溫的室內貯藏,貯藏期間調查重量、外觀、色差值及截切值的變化。金針鮮蕾從開花前兩天到前一天的顏色有變亮、變紅及變黃現象,其L、a、b值分別從52.1、2.4、26.9升高到58.5、11.2、31.5。金針鮮蕾在貯藏期間,低溫貯藏和PE袋包裝處理均可減緩失重、截切值及顏色變化的速度。例如鮮蕾在貯藏五天後的重量變化,盒裝5℃、10℃、15℃及不控溫貯藏(145.6g, 143.6g, 139.2g, 135.9g, 135.9g)顯著低於PE袋處理(149.8g, 149.6g, 149.3g, 148.7g, 148.7g),鮮蕾的失重速度在兩種包裝處理中均隨著貯藏溫度降低而降低。在截切值變化方面,盒裝5℃、10℃、15℃及不控溫貯藏(1,700.3g/cm2, 901.7g/cm2, 597.9g/cm2,腐敗)顯著低於PE袋處理(1,932.9g/cm2, 1,724.9g/cm2, 1,593.3g/cm2,1,307.7g/cm2),截切值降低的速度隨著貯藏溫度降低而降低。盒裝金針鮮蕾顏色變化亦較PE袋裝處理者快,降低貯藏溫度可減緩色差值先升高而後降低的變化現象。 |
英文摘要 | To understand the effect of storage temperature and packaging on the quality of flower buds of edible day lily, it is important in transportation and marketing of flower buds of edible day lily. The flower buds were treated by packaging with OPS boxes (CK) or LDPE bags, every packaging was 150g, and storaged in 5℃, 10℃, 15℃ and uncontrolled temperature in room. Changes of weights, appearance, color values and shearing force were investigated. Color changes of flower buds from two to one days before bloomed up were lighting, redding and yellowing, and the L, a, b values were changed from 52.1, 2.4, 26.9 to 58.5, 11.2, 31.5. Low temperature storage and LDPE bags packaging could retard weight loss, diminution of shearing force, blooming up and molding during 7 days of storaging. For example, after 5 days of storaging, the weight of flower buds with boxes packaging treatments storaged in 5℃, 10℃, 15℃ and uncontrolled temperature (145.6g, 143.6g, 139.2g, 135.9g, 135.9g) were all less significantly than LDPE bags packaging treatments (149.8g, 149.6g, 149.3g, 148.7g, 148.7g). In both packaging treatments, the rate of weight loss of flower buds was retarded by low temperature storaging; the shearing force of flower buds with boxes packaging treatments storaged in 5℃, 10℃, 15℃and uncontrolled temperature (1,700.3g/cm2, 901.7g/cm2, 597.9g/cm2, mold) were all less significantly than LDPE bags packaging treatments (1,932.9g/cm2, 1,724.9g/cm2, 1,593.3g/cm2, 1,307.7g/cm2), the rate of diminution of shearing force of flower buds was retarded by low temperature storaging, too. The color change of flower buds packaging with boxes was faster than packaging with LDPE bags. Storaged in lower temperature could retard the change of color values of edible day lily. |
