| Topic: | Effects of Low Pressure Hot Air Drying on Drying Kinetics and Physicochemical Properties of Dried Ripe Mangoes
|
| Abstract: | The Low Pressure Hot Air Drying (LPHAD) is an innovative drying process that combines advantages of hot air drying and vacuum drying. This drying is capable to produce dried fruits with high quality product, low operational cost and reduced processing time. The aims of this work were to study the effect of LPHAD on drying kinetics and physicochemical properties of dried ripe mangoes. The mangoes were dried at air temperatures of 50, 60 and 70๐C and pressure at 6, 8 and 10 kPa. The results found that the samples dried by LPHAD with high temperature and low pressure provided a higher effective moisture diffusivity (Deff) than Hot Air Drying at atmospheric pressure. The LPHAD also provided more rehydration ratio and lower %shrinkage of the sample than Hot Air Drying. The sample color changes of the LPHAD were lower than that of atmospheric Hot Air Drying. |
