The objective of this study was to investigate the appropriate formulas and methods for the production of bamboo shoots. Total Method 3 was used to study the optimum amount of wheat flour at the concentrations of 5 10 and 15 percent. The tasting parameters of wheat flour were 15 percent. (Framing) and overall liking. Then a suitable amount of baking powder was added in the amount of 1 2 and 3 percent. The average leaf color flavor taste texture and overall preference were 7.50±1.14 7.67±0.80 7.77±0.86 7.57±0.97 and 7.97±0.67 respectively. Physical quality was found to be 52.42±0.02 L* 19.60±0.04 a* and 31.23±0.02 b*. The value of aw was 0.42±0.01. The crispness was 5.33±0.58. The hardness was 5.93±0.11. Based on the chemical quality survey it was found that moisture content was 2 . 2 7 ±0.77 protein content was 12.48±0.00 fat content was 22.47±1.72 the fiber content was 5 . 4 7 ±1.21 the ash content was 7 . 2 8±0.12 and the carbohydrate content was 50.02±0.00 packed in foil aluminum foil bags. With desiccant Preserved at room temperature for 6 weeks moisture content aw values color and texture were analyzed. Moisture content and aw values decrease and result in color values. Slow change the texture decreased slightly. But the product is still framed.

The objective of this thesis was to study the ratio of the black and white sticky rice in the recipe of non-fried rice cracker (Khao-tan) to develop syrup for product topping and to study the appropriate quantity of a cashew nuts for adding in the product. To study a physical and chemical nature of the product. To study the customers satisfaction in product. Firstly the appropriate ratio of the black and white sticky rice was studied. The result was the recipe that had 80% of white sticky rice and 20% of black sticky rice was voted to be the best. For the product topping that had a combination of glucose syrup and sugar was the best. Moreover the quantity of glucose syrup and sugar on product effects the customer’s satisfaction (color smell taste texture and the overall score). For the appropriate quantity of the cashew nut the formula 2 which has a 25% of cashew nuts was voted to be the best. Comparison of which non-cashew nuts and 25% cashew nuts formula the study revealed that the 25% cashew nuts formula had more nutrition (protein fat and fiber). Microbial population count <10 cfu/g. The product is able to keep in room temperature. The customer’s satisfaction reach to 94% in 25% cashew nuts formula.

This research aimed to study the design and development to assist in bringing the car seat into the production process and the risk assessment approach to ergonomics to suit operator. Emphasizing the importance of work and trying to create design tools. Organize work appropriately in accordance with the competency and performance of each individual. Using the principles of biomechanics analysis applied in the analysis along with an assessment of the risks by taking into consideration upon 3 factors. 1. The level of severity. 2. The level of frequency.3. Safety measures at the different parts of the body due to which the body must be borne from the outside and in the work. By bringing knowledge of mechanics the proportion of the body anatomy and physiology is able to create the relationship in a model way of Ergonomics which occurs according to the gesture. The use of tools lifting heavy parts and labor pull push and press researchers found in the process of lifting car seat weighs 14.5 kg dimensions width 45 cm length 55 cm and 100 cm in height is the distance of the car seat to shelve. Assembly point distance of 200 cm research has fixed this issue by adjusting the distance of the car seat and shelves by only 50 cm distance can be reduced down to 150 cm and adjust the position of the lifting cushion to reduce twisting torso while assess the biomechanics model of the behavior of all employee in improvement on quality both before and after work station.

The research objective is to utilize the waste water at 12ºC to 20ºC in exchange with the process water at the temperature of 29ºC. After entering the heat exchanger the process water will have the reduced temperature of 19ºC and then will be delivered to the cooler so the temperature of the process water will further be reduced to 15ºC to involve in the production process. Consequently the cooler’s energy use is lower. Since the common coolers used in these days have problems about the clogged system caused by shrimp residue the cleanup of the system is difficult and the maintenance cost is high. With this problem the research and development of the new heat exchanger is carried out resulting to the Shell and Tube Heat Exchanger type with the angled lid and the waste water flow control pads allowing the water alternatingly running through the lower part and upper part of each pad. The process water will flow in the 6 sets of the stainless tubes with 2 mm. thickness ½ inch diameter and 6 meter length. The space between the set is 5 centimeters for exchanging heat with the waste water flowing outside the tubes. The study conclusion is that the new heat exchanger can reduce the temperature of the process water to 19ºC so it can save the electricity cost of the cooler for 886485 baht per year and make the cleanup easier without taking off the equipment parts thus lowering the maintenance cost as well.
