The stability study of salad dressing products from rice berry broken rice is aimed to study the appropriate amount of vinegar of thick salad dressing from riceberry broken rice. Broken Riceberry rice is further developed by studying the stability by using different amounts of lecithin by soybean lecithin content of 0.15 % Then the physical quality was found that the thickened salad dressing from broken riceberry using soy lecithin was a stabilizing substance with reddish-brown color with brightness (L*) 39.34 ± 0.07 red color value (a*) 11.48 ± 0.04 and yellow value (b*) 5.56 + 0.53. Salad dressing has a soluble solids 33.17 + 0.29 (ºBrix) consistency of stabilization value is 11.48 ± 0.04 cm. pH 3.60 ± 0.01 and titratable acidity 0.43 ± 0.02 %. Proximate analysis is 52.01 % moisture 30.22 % carbohydrate14.86 % fat 2.12 % fiber and 0.79 % ash. During storage at 4 ºC for 4 weeks the total amount of microorganisms and yeasts is less than 10 colonies per gram which pass the requirements of the Community Product Standards. 672/2547.

The purpose of this study is to study a proper quantity of golden bean powder in 4 different levels: 25 50 75 and 100 of the amount of almond powder to study the amount of nutrients in a macaron which made of golden bean powder and to study the level of acceptance of using golden bean powder instead of almond powder in a macaron. The researchers investigated the appropriate amount of golden bean powder in the product by studying the ingredients used in the formulations included golden bean powder by French meringue technique. The researchers used a five-point hedonic scale product to observe sensory of product in appearance color smell taste texture and overall with a taste. The panelists were 40 students in the Department Faculty of Home Economics at Rajamangala University of Technology Phra Nakhon. The Randomized Complete Block Design (RCBD) method was used and compared average scores by Duncan New Multiple Rang Test (DMRT) method at 95% confidence interval. There were statistically significant differences in the levels of golden bean powder all sensory attributes (p< 0.05). Specifically the addition of 75% of golden bean powder had the highest level of acceptance for all sensory attributes with average scores: 4.50 4.42 4.27 4.42 4.27 and 4.42 respectively. The nutrition in macaron net weight 100 grams contain 383 kilocalories of Energy Protein 9.96 grams Carbohydrate 76 grams Sugar 62 grams and Fat 4.38 grams. Based on the comparison of the cost of the standard formula and the golden bean powder it found that the standard formula has a cost of 4.36 baht per 1 pair while the cost of gold bean powder is 2.4 baht per 1 pair. It shows that the golden bean powder will give lower energy than almond powder. Moreover golden bean powder can reduce production costs produce as much as 1 fold.

This research aims to: (1) develop the training curriculum development for enhancing skills in general ability ( 2) evaluate the effectiveness index of the training curriculum development for enhancing skills in general ability and 3) study the samples’ levels of satisfaction. The samples in to study were 10 senior students in regular program. The research instruments included the training curriculum development for enhancing skills in general ability an evaluation of congruence a knowledge and skill test a questionnaire on training satisfaction. The statistics used were the effectiveness index percentages mean standard deviation and paired – sample T test. The results revealed that the training curriculum development for enhancing skills in general ability were highest level appropriation ( X = 4. 67) showing that it was possible for further use. From the pre and post tests on the knowledge and skill testing the trainees different score showed that there was improvement among the trainees at the significant level of . 05. The questionnaire result showed that the trainees were highest satisfied.

The purpose of this research was to develop a short vocational training course on household chemical products and to develop a training course for shortterm vocational training in the production of household chemicals. Population groups Is a general public in Bangkok and metropolitan area by using the voluntary selection as follows. Trial of a short course on the production of household chemicals 10 participants. Evaluation of short courses in household chemical production 10 participants. Technology transfer the short-term training course on household chemical production 20 participants and five speakers. The tools used in the research are as follows: 1. Demand questionnaire 2. Short-term vocational training course 3. Satisfaction assessment. Data analysis using statistical software packages. The statistics used were mean ( X ) standard deviation (SD) and t-test. The research found that 1. Study and development of short courses in the production of household chemicals 1.1 selection of household chemicals that will lead to the creation of training courses based on components Where to buy Price per set Properties of components Safety and hazard Materials and equipment used for production storage use and distribution opportunities 1.2 Creating training courses training course components and training documents to have a sequence of steps that are easy and convenient for the learning of the general public 2.

This research aims to develop the waste heat energy conversion device to generate electricity through a thermoelectric generator (TEG) which is called “CHEU. This device is applied to the LPG cookstove that serves as a waste heat source. The thermoelectric generator with 4 modules in series connection is used to convert heat energy to electricity. The present research shows a modification of the CHEU based on two concepts as follows: (1) re-design the structure for heat transfer improvement and (2) select the high capability of TEG to support a high temperature from a heat source as a result of (1). In this study the modified CHEU is called “MCHEU”. A heat-load condition is set as the gas pressure of LPG which varies in a range of 0.1 - 0.6 kg/cm2 and the throttle valve is fixed approximately at 40% of a fully opened throttle while the air entrainment is fully opened throttle. Also the water-cooling system is used for heat dissipation. Base on the performance evaluation of MCHEU the interesting results are drawn as follows: 1) the maximum temperature difference is on an average value of 278.5oC at a maximum heat load condition while a maximum voltage current and power are on an average value of 18.83 V 5.67 A and 107 W respectively. 2) The temperature difference of MCHEU is higher than that of CHEU with an average value of 50%. 3) The output power obtained by MCHEU is higher than that of CHEU with an average value of 52% and takes less time about 40% for fully charging a battery (12V 7.5Ah). Nevertheless MCHEU usage does not affect the thermal efficiency of a cookstove. 4) The efficiency of an energy conversion obtained by MCHEU is 20% which is higher than that of CHEU about 2%.
