木鳖果是越南的一种常见高营养水果,近年来越南木鳖果产业发展迅速,但对其干燥研究较少,本文采用热泵低温干燥的方法,对木鳖果进行了干燥研究,确定木鳖果干燥的最佳工艺参数,并分析比较干燥对营养成分的影响。结果表明;风速不变,风温越高干燥物料所需时间越短,感官评定就越差,胡萝卜素损失越大;风温不变,风速越高干燥物料所需时间越短,感官评定越差,胡萝卜素损失越大;木鳖果热泵干燥最佳工艺参数为;风温;50℃;风速;10 m ∕s。
木鱉果是越南的一種常見高營養水果,近年來越南木鱉果產業髮展迅速,但對其榦燥研究較少,本文採用熱泵低溫榦燥的方法,對木鱉果進行瞭榦燥研究,確定木鱉果榦燥的最佳工藝參數,併分析比較榦燥對營養成分的影響。結果錶明;風速不變,風溫越高榦燥物料所需時間越短,感官評定就越差,鬍蘿蔔素損失越大;風溫不變,風速越高榦燥物料所需時間越短,感官評定越差,鬍蘿蔔素損失越大;木鱉果熱泵榦燥最佳工藝參數為;風溫;50℃;風速;10 m ∕s。

In recent years, Momordica fruit, as a kind of high nutritious fruit, has been developing rapidly in Vietnam.However, the dr_ying studies for Momordica fruit is lacking.In this paper, the heat pump low temperature drying of Momordica fruit were studied and the optimum drying parameters of Momordica fruit were obtained.The nutrient components of momordica fruit were analyzed after drying.The results show that when the wind speed is constant and the air temperature is increased, the drying time is decreased, the sensory evalua_tion become worse and the loss of carotene is increased; when the air temperature is constant, the higher the wind speed is, the shorter the drying time for Momordica fruit, and the worse the sensory evaluation, and the greater the loss of carotene; The optimum drying process parameters for Momordica fruit were air temperature 50 ℃and wind speed 10 m ∕s.
