This research aims to study Bubble Mesona Chinensis Flavor added with Flaxseed The objective is to study the basic formula of Bubble and to study the quantity of grass jelly juice to substitute water in bubble which has 4 different levels consist of 25 percent 50 percent 75 percent and 100 Percent and to study the flax seed supplementation in Bubble which has 4 different levels consist of 3 percent 6 percent 9 percent and 12 Percent by using the method of randomized complete block design or RCBD. This experimental plan will help assess the sensory quality in appearance color smell taste texture and overall preference by using 9 “Point Hedonic Scale” method. This experimental study used 80 people to test the flavor consist of lecturers and food and nutrition students Faculty of Home Economics Technology Rajamangala University of Technology Phra Nakhon. The results were calculated the average (𝑥̅) to Analysis of Variance (ANOVA) and compare the mean difference at the confidence level 0.05 by using the method of Least Significant Difference (LSD) and Duncan’s New Multiple Range Test (DMRT). Results from the study of grass jelly juice to substitute water in bubble tasters rated Formula 3 for the highest acceptance for color taste texture and overall preference. The average score was 7.98 7.90 7.91 and 7.89 respectively. The tasters rated the highest acceptance score for Formula 2 in flavor with an average score of 7.73 and appearance. The tasters gave the highest acceptance at Formula 4 with an average of 8.02. When analyzed and compared the mean differences it was found that appearance and color when comparing the mean differences it was found that the appearance and color were statistically significant (P≤0.05) in aroma taste texture and overall preference. There was no significant difference (P> 0.05) Results from study of flax seed supplementation in Bubble tasters rated Recipe 1 for the highest acceptance for aroma and taste with a mean score of 7.92 and 7.92 respectively for appearance color and overall preference. 8.06 and 7.95 respectively texture. The tasters rated the same score between Formula 1 and Formula 2 with a mean score of 7.94. when analyzing and comparing the mean difference it was found that Appearance color smell taste and texture There was a statistically significant difference (P≤0.05).
