The purpose of this research was the use of jaggery palm substitute partial sugar in Khanom Chan the suitable ratio of jaggery and sugar (25:50 50:50 and 75:25) were investigated and to study the suitable kneading time which varied at 5 1015 and 20 minutes. Analyze nutritional values and design the experimental by Randomized Complete Block Design (RCBD). Sensory evaluation (color flavor taste texture and overall liking) was tasted by sixty testers with 9-point hedonic scale. After that using 5-point hedonic scale for consumer acceptance test by one-hundred testers. Results showed that the suitable ratio is 50:50 and the suitable kneading time is 20 minutes had high score in every attributes from sensory test. Chemical properties protein fat ash and moisture content were increased while carbohydrate total energy and energy from fat were decrease that compared with basic recipe of Khanom Chan. The partial substitution of sugar with jaggery palm that still yielded an acceptable product for the consumers was 100%.

The replacement of partial sugar with jaggery palm in Khanom Ar-Lua production was further carried out for studying the suitable ratio of jaggery and sugar are 25:50 50:50 and 75:25 and studying the suitable drying time which varied period of time at 8 9 10 and 11 hours. Analyze nutritional values of Khanom Ar-Lua that sugar partially replaced with jaggery palm and Randomized Complete Block Design (RCBD) was applied. Sensory evaluation (color flavor taste texture and overall liking) was tasted by sixty panels with 9-point hedonic scale. After that using 5-point hedonic scale for consumer acceptance test by one-hundred panels. The results showed that Khanom Ar-Lua which use of jaggery palm replacement partial sugar at ratio of 25:75 had the highest score in every properties of sensory test. The suitable drying time is 10 hours. Khanom Ar-Lua that used jaggery palm to replace partial sugar had higher protein carbohydrate and total energy than basic recipe but moisture content and energy from fat are the lower. The consumer acceptance test showed that 99% acceped Khanom Ar-Lua which using jaggery palm replaced patial sugar.

The objectives of this research are to study three standard recipes of coconut milk ice cream and to study the optimal level of jaggery palm in production coconut milk ice cream which sugar partially substituted with jaggery palm at difference levels are 50% 70% and 100% and then the experiment was analyzed with Randomized Complete Block Design (RCBD) at the confidence level was at 95%. Sensory evaluation (appearance color flavor taste texture (smoothness) and overall liking) was tasted by sixty panels with 9-point hedonic scale and the differences of the mean scores were compared with using Duncan’s New Multiple Rang Test (DMRT) in SPSS program for selection the standard recipe and optimal level of jaggery palm. Finally consumer acceptance test on the coconut milk ice cream which sugar partially substituted with jaggery palm was tasted by one-hundred consumers with 5-point hedonic scale. The result showed that the third standard recipe and the 100% of jaggery palm are the most acceptable from panels in sensory evaluation. Afterwards physical properties were analyzed found that viscosity increased up to 705.86 cps 21.56 of overrun value together with 11.26 melting rate. Average score of appearance color flavor taste texture (smoothness) and overall liking are 4.45 4.41 4.33 4.37 4.46 and 4.51 respectively and 98% of consumer accepted using jaggery palm substituted for partial sugar in coconut milk ice cream.
