Abstract

The effects of different plant mucilage clarificants and packaging materials on the characteristic properties of spray dried liquid jaggery (SDLJ) powder during storage were determined. Three different liquid jaggery were prepared using plant mucilage from Aloe vera, fenugreek (Trigonella foenum-graecum L.) and flax seeds (Linumus itatissimum L.) as clarificants, in addition control jaggery prepared without using clarificants. No preservatives were used during preparation of liquid jaggery. Spray drying of liquid jaggery was performed at an inlet air temperature of 160°C and outlet temperature of 80°C with atomising disk speed of 32000 rpm using maltodextrin as carrier. The prepared SDLJ powder was packed in different covers made up of low density polyethylene (LDPE), high density polyethylene (HDPE) and aluminium pouches and stored for six months for further analysis. At every two months interval parameters such as moisture content (%), bulk density (g/cm3), hygroscopicity (%), solubility (sec) and total reducing sugars (%) of jaggery samples were evaluated. Comparative study indicated that control SDLJ powder had poor response for all the parameters during storage in all packaging modes. Plant mucilage clarificants treated jaggery samples showed better shelf life response and were in the order Aloe vera > fenugreek > flax seeds. Aluminium pouches showed better stability for all the characteristic properties analysed with least variation upto six months.
