The study on baked crispy okra sheets (Hit 9701 species) by using a hot air dryer. The objective of this study was to investigate the okra sheets formula and manufacturing procees by hot air dryers with 3 methods; pouring finely blended okra onto the inside tray pouring finely blended okra onto the outside tray and pouring finely blended okra into an aluminum block. It was found that pouring finely blended okra into an aluminum block resulted in the least crack in the dried sheet with the rectangular shape remaining intact. After the forming method is decided on a study was conducted on the temperature to bake okra at 3 levels namely 70 80 and 90 C.It was found that baking okra at 80 C for 4.5 hours was suitable the baking and crispy okra sheets ended up with the lightness(L*) of 49.75 the green (a*) was-2.53 and yellowness (b*) of 23.71. The moisture content was at 5.07 % water activity content was 0.27 The hardness was 5.01 N and the crispness was 4.67. The results of chemical analysis showed that the carbohydrate content was 76.34% crude fibers was 10.72% ash content was 8.24% moisture content was 4.24% and fat content was 0.46%. From the study on the bacteriological quality it was found that the crispy okra sheet products can be stored at room temperature for 28 days.

The objectives of this study were to investigate the three basic egg cake recipes to study the content of four types of perilla frutescens in egg cake at perilla frutescens 0% 1% 2% and 4% percent of total ingredient weight and to study the content of four types of garlic butter in egg cake 0% 5% 10% and 20%. The experiment was conducted by using randomized complete block design (RCBD) to evaluate product attributes in appearance color flavor taste texture and overall liking with the 9- Point Hedonic Scale. There were 80 tasters who were instructors and students at the Foods and Nutrition Major the Faculty of Home Economics Technology at Rajamangala University of Technology Phra Nakhon. Data were analyzed through mean (xˉ) and Analysis of Variance (ANOVA) Least Significant Difference (LSD) and Duncan’s New Multiple Range Test (DMRT) From the study on the three basic egg cake recipes it was found that most of tasters accepted second recipes. In terms of appearance color flavor taste texture and overall liking in medium. When the variance was analyzed and statistical difference was compared it was found that the color flavor and texture was different with statistical significance at the 0.05 level. From the study on the amount of four recipes of perilla frutescens egg cake. it was found that most of tasters accepted perilla frutescens 1%. In terms of appearance color flavor taste texture and overall liking in medium.When the variance was analyzed and statistical difference was compared it was found that the color was different with statistical significance at the 0.05 level. From the study on the amount of four recipes of garlic butter egg cake. it was found that most of tasters accepted garlic butter 10% In terms of appearance color flavor taste texture and overall liking in medium to very When the variance was analyzed and statistical difference was compared it was found that the appearance flavor taste texture and overall liking was different with statistical significance at the 0.05 level.

Use of synthetic surfactant is another choice to increase efficiency of polycyclic aromatic hydrocarbon (PAH) phytoremediation in soil. In this study the toxicity of soil contaminated with anthracene and fluoranthene at total concentration as 0 200 and 800 mg/kg in combination with 2 synthetic surfactants that were triton x-100 and tween 80 at concentration as 0 1 and 10 times of critical micelle concentration (CMC) on seedling growth of Hibiscus sabdariffa and Mirabilis jalapa. Both synthetic surfactants were watered separately on day 13 after inoculation and seedling growth were measured on day 20 after inoculation. The result shown that both H. sabdariffa and M. jalapa could grow in soil contaminated with anthracene and fluoranthene at all concentrations in combination with both synthetic surfactants. Tween 80 at 1 time of CMC were the least toxic to H. sabdariffa while toxicity of all surfactants on M. jalapa were not different. Decrease of plant growth depended on the increasing of PAH concentration in soil. With these reasons both plants were possible to use for PAH phytoremediation at total concentration 200 mg/kg in combination with synthetic surfactant
