Abstract
RSM was performed for the optimization of processing conditions to develop ghewar, traditional sweetmeat of India. Three variables i.e. frying temperature (160-180 ?C), batter temperature (5-10 ?C) and frying time (4-6 minute) were taken to investigate the effect on ghewar responses viz., oil content, moisture content, texture and sensory attributes (OA). The optimum conditions were 160 ?C frying temperature, 5?C batter temperature and 4 minute frying time. Upon optimization, the ghewar yielded the following results: 45.33% oil content, 4.65% moisture, 15.2 N texture (hardness), 54.89 L value, 15.16 a value, 24.97 b value, 58.73 hue value, 29.21 chroma value, 48.07 total color difference, and 0.24 water activity. Storage study of optimized ghewar was also carried out and found shelf stable for 30 days in metallised foil pouches. Hardness values were found to progressively drop from 15.2-9.40 N during the storage period, whereas moisture content, FFA, and peroxide value were found to gradually increase from 3.70-5.12%, 0.33-0.54 %, and 4.8-7.6 meq/kg, respectively.
