In India, the traditional methods of jaggery storage prevalent in
western and eastern regions like open storage, matka, gunny bags etc.
These methods don’t work in Tarai regions because climatic conditions
are not favourable for keeping quality of jaggery as there is very high
humidity in these areas. During mansoon period, due to high humidity
range, jaggery samples get infected with microbial activity and thus
keeping quality of jaggery goes down. Jaggery samples could be stored
in cold storage but sometimes it is difficult to store the samples for
small scale farmers as cost involved is the main constraint for that. Also
the energy consumption is very high. Jaggery from cold storage is used
in off-season at high cost [20].
