Studies on Preparation of Jaggery Granules with Nucleation Technique
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 4
Abstract
Experiments were carried out for the preparation of jaggery granules with the technique of nucleation. The dry seeds (sucrose of size 500-600μ) were used as nuclei for seeding. Experiments were conducted at two brix levels of jaggery syrup with three seeding levels of dry seeds as 50, 100 and 150 g/L to study the effect of seeding on percentage recovery of jaggery granules of different size. The results revealed that the per cent recovery of fine granules (<1000μ) was significantly decreased with increase in seeding level. The recovery of medium (1000-2000μ) and coarse (2000- 3000μ) size granules was increased with increase in seeding levels indicating the effect of nucleation. At 95°B the recovery of fine, medium and coarse size granules was found to be 44.50, 25.92 and 29.58 per cent, respectively under control, whereas at maximum seeding level of 150 g/L, it was 25.64, 35.99 and 40.29 per cent, respectively for fine, medium and coarse granules. Similar effect was attributed at 85°B. Moreover, the color of jaggery granules prepared at 85°B was yellowish compared to 95°B. The nucleation in jaggery syrup during cooling stage enhances the process of granulation. All size granules (fine, medium and coarse) were seen attractive in terms of colour, appearance and texture.
