Abstract
An experiment entitled “Effect of different drying techniques on quality of
dried kasuri methi (Trigonella corniculata) leaves” was carried out at College of
Agriculture, Nagaur, Agriculture University, Jodhpur (Rajasthan). Kasuri methi
(Trigonella corniculata) is a bushy, herbaceous, slow growing yearly spice crop,
primarily grown for herbage that to for dry herb and seed. Its leaves are pinnate,
leaflet size is 1.25-2.0 cm. Flowers color is usually bright orange or yellow in close
racemes. The present investigation was focused on thethe effect of different drying
techniques namely shade drying, sun drying and solar tunnel drying on nutritional
and sensory quality of dried kasuri methi leaves.The proximate composition analysis
was performed after drying involving determination of moisture, fat, protein, ash, acid
insoluble ash, crude fiber and carbohydrate. Also other nutritional determinants like
of calcium, riboflavin and ascorbic acid were estimated. The weighed kasuri methi
leaves were taken and dried by different drying techniques. The weight reduction of
the samples as measured periodically until the constant weights were observed. From
the experiment, the initial moisture content of the fresh kasuri methi leaves was found
to be 71.27%. The final moisture content of the different drying methods drying
samples were found as 5.41% in shade drying, 5.17% in sun drying, and 5.37% in
solar tunnel drying respectively. Total drying time required for moisture removal to
very lowest level were found to be as 48 hr, 5hr, 3hr for shade, sun and solar tunnel
drying, respectively. Overall performance and quality characteristics is found better in
shade drying method samples as compare to other drying method but the solar tunnel
drying method is just marginally lacking behind sensory attributes, which is the
fastest drying method in all.
