Thai desserts have unique appearance and characteristic cause ingredient and processing. Thai desserts processing is very complicate which Thai dessert is decreased to produce and consume. Difficulty Thai desserts processing were surveyed and ranked. Top 5 of difficulty processing were Kanom Kasornlamjeak Kanom Krok Kanom Beaung Thai Kanom Thong Ekk and Kanom Jamongkut. Kanom Kasornlamjeak consists with wrap flour and filler which made from coconut. The process of wrap flour is complicate. Flour mixing time (20 30 and 40 min) was studied. Increasing mixing time improved wrap flour forming. The sensory evaluation result showed that Kanom Kasornlamjeak with flour mixing time 20 min got a good preference score from the panelists. Kanom Krok consists with rice flour and coconut milk. The characteristic of Kanom Krok is crispy flour and forming. The concentration of lime water (0.5 1.0 and 1.5%) was studied. Increasing lime water concentration increased crispiness and hardness of Kanom Krok. Kanome Krok with 1.0% lime water received the highest preference score. Kanom Beaung Thai consists with casing flour and filler. The important characteristic of Kanom Beaung is crispy casing flour. The concentration of lime water (0.5 1.0 and 1.5%) was studied. Increasing lime water concentration increased crispiness and hardness. The sensory evaluation result showed that casing flour with 1.0% lime water got a high preference score. Coconut milk and wheat flour are the important ingredients in Kanom Thong Ekk. They were mixed and stirred until smooth paste to press in a plastic mold. Cooking temperature; 60 65 and 70C were studied. Increasing temperature increased oil separation and gelation. Kanom Thong EKK with cooking temperture at 65C received the highest preference score.Kanom Jamongkut is a Thai dessert that the shape looks like a crown. Watermelon seeds are the most important ingredient which are coated with sugar syrup and composed to be a crown. The amount of watermelon seeds coated with sugar were studied which were 50 100 and 150 seeds per batch. Increasing watermelon seed per batch to coat it with sugar syrup it did not look like a crown. Sensory evaluation result showed that 50 watermelon seeds coated with sugar received highest preference score.

Ja Mongkut is a kind of Thai dessert which the process is complicated. The most important processes is roasted watermelon seeds with sucrose solution to make the sugar gains like a thorn shaped that spent about 180-240 minutes caused Ja Mongkut is not popular to produce and consume. Effect of sucrose concentration on the thorn shaped of Ja Mongkut was studied. The sucrose concentration (45 60 and 75 %) was sprayed on the watermelon seeds during roasting. Watermelon seeds were sprayed with high sucrose concentration spent 25-30 minutes to product the thorn shape but it had large sugar gain. Sensory evaluation showed that the watermelon seeds sprayed with 45% sucrose concentration obtained the highest appearance and overall acceptance.

This research aimed to study the basic recipes of making “Pla Nil Yong” were studied. The Completely Randomized Design (CRD) was used to evaluate the sensory property in overall liking the characteristic appearances color flavour taste and texture. There were used 30-testers and a 9-Point Hedonic Scale were used. The study found that the second basic recipe had the highest scores in overall satisfaction. The 3 types of heating of fish meat production used were: Steaming Pressure Cooking and Broiling. It was found that the Pressure Cooking had the highest scores of all averages. The Steaming and the Pressure Cooking made the fish fiber fluffier than the Broiling. By the color variation of finishing product was as follow: Brightness (L*) 53.91 Red (a*) 10.50 Yellow (b*) 30.25 aw 0.57. By the amount of total microorganism 2.5x102 CFU/g Yeast and Fungus <25 CFU/g Moisture 4.75% Fat 6.54% Protein 48.06% Ash 7.47% Fiber 0.54% Carbohydrate 32.64%. The study of 3-differrent-temperature of storage were 28 40 and 50 degree Celsius. In 90-day storage checking; found that all of the three variation had overall liking the characteristic appearances and color were different but flavour taste and texture were of no difference. The total amount of microorganisms: yeast and fungus were a lower standard. The production cost of Pla Nil Yong is 397.10 bahts per kilogram.

This paper aimed to study the process of making instant Pad Thai powder by Spray Drying method. The appropriate temperature of hot gas and the quantity of Maltodextrin in processing instant Pad Thai powder by Spray Drying method were studied. Factorial in Completely Randomized Design (CRD) was used. The study found that the appropriate quantity of Maltodextrin was 20% and the appropriate temperature for in and out hot gas was 150/90 ºC. The color variation of the finishing instant Pad Thai powder was as follow: Bright colors L* 88.32 Red a* 0.99 Yellow b* 8.26. The color variation after cooking the product was: Bright colors L* 30.73 Red a* 3.08 Yellow b* 8.25. aw 0.22. The moisture of the powder was 1.24. Then the consumer satisfaction was studied by using 3 types of Pad Thai Noodles; Pad Thai Noodles with Instant pad Thai Powder Pad Thai Noodles with regular Pad Thai sauce and Pad Thai Noodles sold in general market. Randomized Complete Block Design RCBD was used. The study of the consumer satisfaction revealed that there was no difference between pad Thai Noodles made with Instant Pad Thai Powder and Pad Thai Noodles made with regular Pad Thai sauce at the statistical significance (p>0.05). The testers rated the overall taste of Pad Thai Noodles at 7.57. Next the researcher studied the expiration period of Instant Pad Thai Powder by packing the product in double vacuum foil and storage the product at 4 different temperatures 30 35 45 and 55 degree Celsius. Then the product was studied to evaluate the physical chemical microorganism and sensory property. The product kept at 55 ºC was the most different of the four storage products at p ≥ 0.05 with the highest level of consumer satisfaction at color = 7.33 smell = 7.30 taste = 7.90 texture = 7.57 and total = 7.40. The amount of microorganism yeast and fungus were at the safe level to comsume.

This research work was to study the effect of surface treatment of natural fiber and the effects of type and content of natural fiber on the development of acoustic material from natural rubber foam /natural fiber composites. The surface treatment used for this research work was sodium hydroxide (NaOH) treatment. NaOH Concentrations and treatment times were varied from 0 to 15 %wt. and 0 to 30 min respectively. Natural fibers used for this work were bagasse fiber (BF) and oil palm fiber (OPF). The suitable condition for surface treatment was estimated by fiber length and diameter (L/D) ratio and morphology of natural fiber. The result suggested that L/D ratios tended to increase when NaOH concentrations and/or treatment times increased except for NaOH concentration of 15 %wt. L/D ratios of OPF after surface treatment were changed more than those of BF. The suitable conditions of NaOH treatment for BF and OPF were NaOH concentration of 10 %wt. and surface treatment times of 30 and 10 min respectively. The effects of fiber type and content on sound absorption properties of natural rubber foam /natural fiber composites were investigated by cell characteristics sound absorption coefficient DMA analysis and bulk density. Both treated BF and OPF with suitable treatment condition were varied from content of 0.0 to 10.0 %wt. The result showed that the cell size of composites tended to decrease with addition of natural fiber whereas number of foam cell per unit volume increased. After adding natural fiber more than 2.5 %wt. cell size of composite foam and number of foam cell per unit volume tended to change the inverse direction. Natural fiber in composites enhanced the sound absorption efficiency. Sound absorption coefficient of composites adding BF was more than that of composite adding OPF. The addition of natural fiber enhanced the elasticity of composites and that increased sound absorption efficiency. NaOH treatment led to creation of strong interfacial bonding between natural fiber and natural rubber and enhanced the sound absorption efficiency. Density of NR composite foam increased with increasing natural fiber content.
