The production of hard candy from curry leaf (Murraya koenigii)

Abstract

This research had been carried out to determine the finest formulation of hard candy from Murraya koenigii (curry leaf). In this research, there were 6 samples tested which were sample R (hard candy contains 0% of curry leaf), sample A (hard candy contains 2% of curry leaf), sample B (hard candy contains 4% of curry leaf), sample C (hard candy contains 6% of curry leaf), sample D (hard candy contains 8% of curry leaf) and sample E (hard candy contains I 0% of curry leaf). Analysis that were carried out in this research were colour analysis ('L', 'a' and 'b'), moisture content, water activity, vitamin C and sensory evaluation. The attributes for sensory evaluation were colour, shape, aroma, taste, hardness and overall acceptance. For determination of colour, results show that sample R had the highest value 97.41±0.07 for the lightness 'L'. The lowest 'L' value 91.99±0.05 was obtained from sample E. The results also show that, there were significant different (p<0.05) between each sample but no significant different between sample C and D. For the 'a' value, sample R showed the highest value 0.24±0.03 and sample D exibited the lowest value -1.60±0.04, which lead to greenness. There was no significant different between sample A, D and E but there was significant different between other sample. For the 'b' value, sample C exhibited the highest value 6.19±0.03. While sample R were the lowest 2.03±0.0 I. There was no significant different (p<0.05) between sample A and D, and between sample B and E. Sample A had the highest moisture content of 4.99±0.87 while sample C had the lowest 2.56±1.59. There was no significant different (p<0.05) between sample R, D and E. For water activity, sample E had the highest value and sample C had the lowest. Every sample had a low value of vitamin C. Sample D was the most acceptable by panel due to the highest mean score in three attributes shape, taste and overall acceptance. From the result there were no significant different in the overall acceptance which means all of the sample are accepted at the same level.
