    摘要:

    通過三因素二次通用旋轉組合試驗設計,，考察了預凍速率、干燥室壓力和加熱板溫度對真空冷凍干獼猴桃切片品質的影響，得出了獼猴桃凍干切片品質與各因素間的回歸模型。3個因素對獼猴桃凍干切片質量的影響均極為顯著 (p＜0.01＝；影響主次順序為預凍速率,、干燥室壓力、加熱板溫度。獼猴桃凍干切片的最優(yōu)生產工藝參數為預凍速率0.6℃/min,，干燥室壓力73.6 Pa，加熱板溫度

    Abstract:

    40℃,。 The effects of the factors of pre-freeze rate, dry chamber pressure and board temperature on quality of vacuum freeze-dry kiwifruit slice were investigated with three-factor second order general revolving combination design, and the regression model with high reliability was obtained between the quality of kiwifruit slice and the factors. The results showed that the three factors all had very significant influence on quality of kiwifruit slice (p＜0.01）. The influencing sequence from significant to common is pre-freeze rate, dry chamber pressure and board temperature. The optimally technical parameters are 0.6℃/min of pre-freeze rate, 73.6Pa of dry chamber pressure and 40℃ of board temperature.
