The objectives of this study were 1) to study the basic recipe of Khanom Raerai and 2) to study the substitute amount of rice flour by using Tubtim Chumphae Brown rice flour in Khanom Raerai at four different levels of 0% 40% 50% and 60% by total rice flour weight. Randomized Complete Block Design (RCBD) to apply the sensory quality in terms of appearance color odor texture and overall preference using a 9-Point Hedonic Scale tasting method tasted by 40 untrained students from Foods and Nutrition Program Faculty of Home Economics Technology Rajamangala University of Technology Phra Nakhon. The data was verified by mean Analysis of Variance (ANOVA) and then compared the mean difference at a 0.05 confidence level by using Duncans New Multiple Range Test (DMRT) method. The results were analyzed by a computer software program. The results found that 1) the basic Khanom Raerai recipe made from rice flour tapioca flour arrowroot flour soybean oil and water was 27.25% 1.63% 1.63% 4.09% and 65.40% by total ingredients weight. The tasters verified the sensory quality in appearance color odor texture and overall preference. The mean values were 7.80 7.40 7.27 7.67 and 7.93 respectively at a moderate level of liking. The results found that almost all sensory aspects were significantly different at the 0.05 level except for color and odor. 2) the amount of Tubtim Chumphae brown rice flour substitutes for rice flour in Khanom Raerai it was found that the tasters accepted 40% by weight of rice flour in terms of appearance color odor texture and overall preferences. The mean values were 8.60 8.20 8.40 8.33 and 8.67 respectively at the level of liking the most. The sensory results found that all sensory characteristics were not different at the 0.05 level. Therefore the Khanom Raerai recipe uses Tubtim Chumphae brown rice flour substitutes for rice flour at the 40% level as the formula accepted in this study.

The purposes of this research were developing for 1) to study the basic recipe of Rae-rai 2) to study the preparation process of sunchoke flour 3) to study the amount of rice flour substitution with sunchoke flour in Rae-rai 4) To study the consumer acceptance in the Rae-rai with rice flour and sunchoke flour and 5) to study the nutritional value of basic recipe Rae-rai and substitutes for sunchoke flour. By using the basic recipe of Thanawit (2018) then apply the selected recipe study of the preparation process of sunchoke flour. And using the amount of rice flour substitution with 4 levels of sunchoke flour 15% 20% 25% and 30%. Acceptance tests were conducted by panelist. The results showed that the preference scores for color smell taste texture overall preference and appearance differing with statistical significance (p≤.05) by the tasting operator lowering the liking score when the amount of rice flour substitute was added to the sunchoke flour in increasing ratio and the score of the most favorite dessert in 20% sunchoke flour for consumer testing In the composition of ingredients that are beneficial to odor health Overall inclination texture and taste at the level of acceptance like all aspects most of them know and have eaten all this dessert. Is a product that has more nutritional value for health accepting after the trial of eating Rae-rai. The appropriate amount is 15 grams / 4 pieces. The appropriate price is 30 baht per 1 unit of packaging. Interested when the product is sold by the nutritional value of the basic recipe and the replacement recipe found that the composition in the inulin recipe the substitution amount is 12.26 grams. Basic recipe moisture content is higher than the replacement recipe. Carbohydrate substitution recipe is higher than the basic recipe for the replacement recipe protein which is higher than the basic recipe for the replacement recipe fat which is higher than the basic recipe.
