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 development of fruit cake products using quinoa flour mixed with rice flour and vegetable fat were aimed ( 1) to study the optimal ratio of quinoa flour and rice flour as a substitute for wheat flour in fruit cake products ( 2) to study the use of vegetable fat as a substitute for butter in fruit cake products using quinoa flour and rice flour mixture ( 3) to study the nutritional value of basic fruit cake and fruit cake using quinoa flour and rice flour mixture and using vegetable fat instead of butter and ( 4) to study consumer acceptance of fruit cake products that using quinoa and rice flour mixture by using vegetable fat instead of butter. The results showed that the appropriate ratio of quinoa and rice flour mixture as a substitute for wheat flour was a ratio of 50: 50 which achieved preference ratings higher than the ratio of 60: 40 and 70: 30 based on sensory evaluation. The study on the use of vegetable fat as a substitute for butter in fruit cake recipes showed that the use of fat obtained from rice bran oil had higher mean scores of favorability than the use of fat from coconut oil and fat from olive oil. The nutritional value of fruit cakes using the mixture of quinoa and rice flour and fat from rice bran oil as a butter substitute was compared with the basic recipe. It was found that the nutritional value was not much different. The fruit cake recipe that uses quinoa flour mixed with rice flour and fat from rice bran oil in 100 grams can provide 368.30 kilocalories with a moisture content of 32.22% protein 6.02% carbohydrates 41.10% fat 19.98% ash 0.68% and calcium 507.57 mg. And from the results of the acceptance study of 120 general consumers who had opinions on fruit cake products that use quinoa flour mixed with rice flour and fat from rice bran oil 4 3 % found that fruit cake products had novelty and interesting followed by 25% of the nutrients that were beneficial to the body with 100% acceptance of the developed products.

Rice flour-based cookies are gluten-free products. Cricket powder and isolated soy protein are alternative protein sources which can provide desirable nutrition. Xanthan gum is one of the hydrocolloids affecting the texture of cookies. This study investigated the effect of cricket powder (CP) isolated soy protein (ISP) and xanthan gum on the physical chemical and sensory qualities of rice flour-based cookies. The substitution of rice flour with two protein sources CP (25 and 35%) and ISP (0 25 and 35%) in the cookie formulations which were evaluated for their qualities using a 2x3 factorial arrangement in a completely randomized design. The result showed that when CP increased or ISP decreased the diameter of the product significantly (p≤0.05) increased but the hardness of the product significantly (p≤0.05) decreased. The effect of xanthan gum (0 0.14 0.28 and 0.42%) on the quality of products was also evaluated. It indicated that the increase in xanthan gum content significantly (p≤0.05) increased water activity moisture content and hardness of product while the liking score for hardness and overall liking significantly (p≤0.05) decreased. Therefore the optimal formula of rice flour cookies was 25% CP and 35% ISP for rice flour replacement without xanthan gum.

The aims of research were to study (1) a basic formula of rice noodles’ production. (2) the production of jobs tears flour and rice flour in rice noodles’ production. (3) the quantities of using jobs tears substituting for rice flour in noodles’ production. And (4) consumers’ acceptance of rice noodles product from jobs tears flour. The results showed that the first formula was chosen to be the basic formula. This formulation containing 10% rice flour 3% tapioca flour 26% water and 0.5% vegetable oil. The results of physical qualification between jobs tears flour and rice flour showed that the lightness (L) of jobs tears flour lower than the lightness (L) of rice flour (p≤0.05). And the value (a*) showed redness and the value (b*) showed yellowness higher than rice flour (p≤0.05). Humidity and water activity (aw) of general rice flour is not different from jobs tears flour considered by sensory test with ratio of jobs tears flour to rice flour of 20:80. This ratio got more preference the ratio 40:60 and 60:40 (p≤0.05). According to the consumer test (100 consumers) the Noodles by Partially Substituting Rice Flour with Jobs tears Flour was accepted as the novel and delicious product by 98% consumers. Moreover and 92% of consumers decided to buy the product containing 250 g in the plastic bag with the price of 25 Baht.

The objective of this research was to compare the quality of Kanomchan which replace rice flour with Homnil rice flour Riceberry rice flour and Sangyod rice flour and to study the quantity of modified starches used in frozen Kanomchan products. Sensory evaluation of 30 panelists using 9 points Hedonic Scale. It was found that the panelist preferred Kanomchan that was made from Sangyod rice rather than the Kanomchan made from Riceberry rice flour and Homnil rice flour (p≤0.05). In the recipe of Kanomchan consist of 40.98% coconut milk 37.30% flour 10.65% cassava starch 9.02% cassava starch and 2.05% rice flour. Then using Sangyod rice flour in Kanomchan products to study modified starches suitable quantity for frozen Kanomchan products by three standards. Constitute 1% 3% and 4% by replacing of cassava starch. And compared with base recipe that not add modified starches. Then Kanomchan was freeze at -18 °c for three days. Before defrost with microwave and heated with 640 watts of microwave power for 2 minutes. The result found that frozen Kanomchan product which adding 3% modified starch had the most sensory points in every attributes. Except taste score texture (toughness) and overall score more than non-modified starches recipe (p>0.05). Then study three types of hydrocolloids. (guar gum gum Arabic and carrageenan) for develop quality of frozen kanomchan products by add hydrocolloids 0.1% for amount starches in frozen kanomchan products that using. Then freeze at -18 °c and reheat with microwave which had 640 watts of microwave power for 2 minutes. The result is guar gum had the most of linking points good texture that suitable with frozen Kanomchan products than caragenan and gum arabic. Results of the selection of the pattern of Kanomchan in packaging. By all experts choose a rose mold. and the packaging style numbrr 1 with the accompanying reasons name and the product brand prominently easy to remember beautiful colors look appetizing and linked the Thai dessert.
