In this study, Amla segments dried in different drying methods like sun drying and
solar tunnel drying and with different pre-treatments like 2 per cent Sodium Chloride and 0.1 per
cent Potassium metabisulphite solutions. The treated samples significantly showed variations in
some quality parameter of amla segments. The samples dried in solar tunnel dryer gave lower
moisture content compared with that of sun dried samples. The lowest water activity were found
to be in 2 per cent Sodium Chloride pre-treated amla segments dried in solar tunnel drying. Solar
drying of pre-treated amla segments in solar tunnel dryer resulted in 20-30 per cent reduction in
drying time as compared to open-air sun drying. The highest rehydration ratio was found to be in
0.1 per cent Potassium metabisulphite treated amla samples. The quality of rehydrated amla segments
dried in solar tunnel dryer was superior when compared to amla segments dried in open sun drying
method. The highest vitamin C retention was found to be 125.68 (mg/100 g) in untreated amla
samples dried in solar tunnel dryer. The quality of rehydrated amla segments dried in solar tunnel
dryer was superior when compared to amla segments dried in open sun drying method. The
problem of interruption by rain and cloudy period was solved. The samples dried in the solar
tunnel dryer were completely protected from rain, insectsand contamination by dust and were of
good quality dried product.
