The investigations were carried out to study the effect of different particle size and packaging
materials on storability of jaggery powder on the basis of changes in chemical composition and organoleptic
characteristics. Jaggery powder of three different grades viz., coarse (0.500 -0.708 mm), medium (0.351 - 0.420
mm) and fine (0.211 - 0.296 mm) were prepared and packed in 100 gauge polyethylene bag. The samples were
stored at room temperature for the period of 6 months. In order to optimize the particle size of jaggery powder,
the changes in chemical composition and organoleptic properties were evaluated during storage. The results
revealed that change in chemical composition was lower in case of coarse jaggery powder. The coarse jaggery
powder having particle size in the range 0.500-0.078 mm) was found more acceptable among all other powder
sizes after storage period of six months in terms of its chemical properties and organoleptic characteristics
