The development of dried water chestnuts is aimed to study the appropriate concentration of calcium chloride for preparation of water chestnuts before drying process; a proper duration for drying process by using hot air oven; the comparison of drying processes between solar dried-oven and hot air oven; and the use of dried water chestnuts for Thai dessert products. The research result can be summarized that the concentration of calcium chloride solution is 0.25% that yield the best quality for water chestnuts which had 0.63 water activity (aw); 3.47 moisture content color value of (L*) 62.38 (a*) 4.82 (b*) 35.66; and 0.79 specific density. It also yields the best quality to rehydrate water chestnuts comparing to their previous condition. A proper drying duration of water chestnuts soaking in 0.25% calcium chloride by using solar dried-oven at different duration of drying. Dried water chestnuts dried at 9 hours and average dehydration temperature 50-55 Celsius had 0.31 water activity (aw); and color value of dried water chestnuts is of bright red with (L*) 80.14. Also the brightness of rehydrated water chestnuts decreased to (L*) 58.30 and firmness (Newton) to 68.70. By using hot air oven the study of a proper duration of soaking water chestnuts in 0.25% calcium chloride indicated that drying for 3.5 hours of drying time water chestnuts had highest moisture content while drying for 4.5 hours had the least moisture content. Therefore decreasing of moisture content depends on the drying duration with different methods. The study also found that dried water chestnuts using solar dried-oven had less water activity (aw) and moisture content than those using hot air oven. Moreover dried water chestnuts from solar dried-oven had brightness value (L*) less than those from hot air oven; but dried water chestnuts from solar dried-oven had more reddish yellow than those from hot air oven. Also there is similarity of specific density of water chestnuts from both drying methods. For rehydration of water chestnuts color values of these 2 methods are similar. However color which is similar to fresh water chestnuts is resulted by drying water chestnuts with hot air oven; and the brightness (L*) of water chestnuts texture increases. Also value of (a*) and (b*) of water chestnuts from hot air oven are more reddish yellow. Meanwhile firmness (Newton) from drying with hot air oven is able to maintain strength or firmness of water chestnuts. Percentages of water chestnuts absorption are similar between two drying methods. The sensory test of Thai pudding using dried water chestnuts indicated that there is no statistically significant at 95% level of average scores in the terms of color smell taste dried texture and overall acceptance. The result of microbial analysis from dried water chestnuts found that there is no microorganism. In addition the result of raw material cost calculation showed that drying 1 kilogram of fresh water chestnuts yielded 108 grams of dried water chestnuts. The total cost of production is 48.43 Baht per kilogram.

The study objective was to the basic recipe of Ready Made Mee-Krob (Crispy Rice Noodle) sauce were evaluated the sensory property appearance color flavor taste texture and overall acceptability by 7-Points Hedonic Scale. The first basic recipe including sugar tamarind juice lime juice fish sauce shallots bean paste and tomato sauce had the highest scores in overall acceptability. Mee-Krob sauces were packed in retort pouch and stored at room temperature for 90 days. The color-values (L* a* and b*) of the product were decreased while the viscosity and pH of the product were increased during storage. The microbiological shelf life of Mee-Krob sauce were assessed. The microbial population remained under 10 CFU/g for 90 days. Consumer acceptance testing was a passive measure to indicate the acceptance of the product by Home Use Test. The consumers gaving a high degree of product acceptance indicated that the product was well accepted.

The objective of this research is 1) to develop Phajok designs by computer sewing machine 2) to study the opinions of consumers towards Phajok designs which have been developed by way of computer sewing machine and 3) to study the satisfactions of consumers towards lady hand bag products with Phajok designs developed by way of computer sewing machine. Sampling groups are 400 ladies in Bangkok Metropolis and its perimeter who are interested in Thai fabrics. Tools used are Questionnaires and 15 models of lady hand bag product prototype; data analysis by using statistics on percentage mean and standard deviation with the actions by conducting the study on the original 15 Jok Designs and then developing the sewing by computer on 3 designs for decorations on lady hand bags in 5 different designing models whereby 15 developed modeling bags are obtained. Result of the research finds that most of the consumers are 41 years old and over; their educations are in Bachelor Degree level or its equivalency; their marital status are married; occupations as the private enterprise staffs earning incomes ranging from 15001 Baht to 20000 Baht and buying Thai clothing goods from tourist attraction places; reasons for buying are to take them for giving as souvenirs and have ever bought Phajok products; thing for consideration in buying Phajok is the designs; Phajok are utilized in making dresses or decorating the dresses; interested in Phajok designs developed by computer sewing machine and are of the opinions Phajok can be used as the products in dress decorating. On the selections in buying the lady hand bangs consumers are found to consider the aspect of the model with the likes on the decorations with the designs sewn by silk threads and are of the opinions that the model of the lady hand bags decorated with Phajok designs developed by way of computer sewing machine is suitable. Result of the analysis on the satisfactions of the consumers towards lady hand bags sewn with Phajok designs developed by way of computer sewing machine of all models are in high level.

The objective of this research is to study the implementing the agricultural residue to the design of outdoor paving block for lowering the building temperature. The base layer admixture (layer no.1) is selected from cement type1: quarry dust: rice husk: rice straw: water ratios equal to 1: 3: 0: 0: 0.3 1: 1: 0: 1: 0.5 1: 1. 0.25: 0.75: 0.5 1: 1: 0.5: 0.5: 0.5 1: 1: 0.75: 0.25: 0.5 and 1: 1: 1: 0: 0.5 by weight. The surface layer admixture (layer no.2) is white silica cement: yellow stone chip no.4: water equals to 1: 4: 0.3 by weight. The exterior floor-covering blocks were tested following density testing water absorption testing compressive testing and surface temperature testing compare with laterite sandstone paving concrete block marble and granite. Resulting the best ratio of cement type1: quarry dust: rice husk: rice straw: water is 1: 1: 0.75: 0.25: 0.5 that has properties at 28 days following 1939.43 kg/m of density 14.97 % of water absorption 284.69 ksc of compressive strength and lower than other paving blocks around 3 – 13 degrees Celsius of surface temperature
