Drying of ginger slices Evaluation of quality attributes

The ginger slices (0 9 kg) were dried in a relative humidity convective drier (lab-scale hot-air drier equipped) which works with a tempera-ture range from 30 to 75 C relative humidity (10–40%) air velocity (2 ms−1) and power of 1 2 kw as previously described in detail by Osae Zhou Alolga et al (2019) The ginger slices were dried under

Comparison of three types of drying (supercritical CO2

Based on nine quality parameters (textural colour and sensory properties) a mathematical model for calculating a single total quality index (TQI) of dried apples packed in different types of packaging in normal and modified atmosphere has been introduced At the beginning of the study apples dried in supercritical CO2 had the best scores
