Vacuum drying characteristics of eggplants

Journal of Food Engineering, 2007
Abstract The vacuum drying characteristics of eggplant were investigated. Drying experiments were carried out at vacuum chamber pressures of 2.5, 5 and 10 kPa, and drying temperature ranging from 30 to 50 °C. The effects of drying pressure and temperature on the drying rate and drying shrinkage of the eggplant samples were evaluated.

Novel ultrasonic-assisted vacuum drying technique for dehydrating garlic slices and predicting the quality properties by low field nuclear magnetic resonance.

Food Chemistry, 2020
A novel ultrasonic-assisted vacuum drying technique for dehydrating garlic slices to give high quality products was developed. Garlic slices were dried at 60 °C using four methods: ultrasonic-assisted vacuum drying (USVD), vacuum drying (VD), ultrasonic ...

Numerical analysis of heat and mass transfer in kiwifruit slices during combined radio frequency and vacuum drying

International Journal of Heat and Mass Transfer, 2020
Kiwifruit slices subjected to combined radio frequency (RF) and vacuum drying undergo a complicated process, including electromagnetic heating, heat and mass transfer along with a phase change of evaporation and shrinkage under a low pressure. The aim of

Evaluating drying feature differences between ginger slices and splits during microwave-vacuum drying by hyperspectral imaging technique.

Food Chemistry, 2020
This study aimed to investigate the difference between ginger slices (vertically cut) and splits (horizontally cut) during microwave-vacuum drying (MVD) procedures. MVD ginger slices showed a higher shrinkage rate and a higher hardness value, with a more

Effect of high-humidity hot air impingement blanching and pulsed vacuum drying on phytochemicals content, antioxidant capacity, rehydration kinetics and ultrastructure of Thompson seedless grape

Drying Technology, 2020
A new pretreatment method using high humidity hot air impingement blanching (HHAIB) followed by pulsed vacuum drying (PVD) was employed for Thompson seedless drying. The effect of this dehydration technique on phytochemicals content (ascorbic acid, total
