Abstract
An experiment entitled “Effect of different drying techniques on quality of
dried moringa (Moringaoleifera) leaves” was carried out at College of Agriculture,
Nagaur, Agriculture University, Jodhpur (Rajasthan). Moringa (Moringaoleifera) is
known as the functional food, provides health benefits beyond basic nutrition and may
play a vital role in reducing and minimizing the risk of certain diseases and other
health conditions.It has a great significance as an important food commodity and
‘natural nutrition of the tropics’. It is considered as a highly nutritive vegetable in
many countries especially in India, Pakistan, Philippines, Hawaii and many parts of
Africa due to its enriched leaves, fruits, flowers and immature. The present
investigation was focused on the evaluation of the study of different drying techniques
on quality of dried moringa leaves using different drying methods namely sun drying,
shade drying and solar tunnel drying. Also analysis of the proximate composition
such as moisture, fat, protein, ash, acid insoluble ash, fiber and carbohydrate. Also,
the nutritional determination of calcium, ascorbic acid and riboflavin were estimated.
The weighted moringa leaves were taken and dried in different drying methods and
conditions. 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 moringa leaves was found to be 75.12g per 100g and 6.76g per 100g. The
final moisture content of the different drying methods drying sample was found
6.73g in sun drying, 6.91g in shade drying and 6.65g in solar tunnel drying
respectively. Total drying time required for moisture removal to very low level or
negligible weight reduction of samples were found to be as 48hr, 7hr, 3hr for shade,
sun and solar tunnel drying respectively.
