The purposes of this research were1) to study the process of dried banana leaves’ dyeing with natural dye and scientific dye and 2) to study the results of dried banana leaves’ dyeing with natural dye and scientific dye. Dried banana leaves were bleached by using three formulas as follows: 1. Mix Haiter with water in the ratio 1:1 2. Mix Haiter with water in the ratio 2:1 and 3. Mix Haiter with water in the ratio 3:1. Soak 300 grams of the dried banana leaves for 5 days and record the results. The result of this experiment indicated that the third formula wassuitable to whiten and toughen dried banana leaves. After choosing the suitable formula for bleaching

The objective of this research was to find the suitable types of carving style for five fruits and vegetables e.g. pumpkin carrot radish cantaloupe and Japanese cucumber. Physiological changes and methods to improve quality and extend shelf-life were also studied. The results showed that the leave-carved operations stimulated the respiration rate ethylene production and the electrolyte leakage more than flower-carved operations. These responses depended on the size of wound and surface area that contacted with atmospheric oxygen. Two concentrations of peroxyacetic acid (60 and 80 mg/L) solutions showed the efficacy in reducing microorganism populations better than sodium hypochlorite (50 and 75 mg/L). The three firming agents of calcium chloride (0.5-1.5%) calcium lactate (0.5-2%) and calcium propionate (0.5-2%) could improve texture at different concentrations. The combination effects of peroxyacetic acid (80 mg/L) and firming agents (0.5% calcium chloride 1.5% calcium lactate and 2% calcium propionate) and/or 0.25 and 0.5% of chitosan coating were applied on rose and lotus-carved fruits and vegetables. All off flower-carved fruits and vegetables were stored at 5?1oC in clamshell container. Then they were placed in a control temperature chamber at 25?1oC every day for 3 hours until the end of shelf-life. The results showed that 0.25 and 0.5% chitosan coating had the best coating solutions for extended shelf-life of carved pumpkin carrot and cantaloupe. The control treatment dipped in tap distilled water showed the suitable treatment for rose-carved radish and lotus-carved Japanese cucumber. The best chemical treatment for each fruit and vegetable was repeated in the storage experiment and then they were stored at 5?1oC in clamshell containers to determine the shelf-life of three carved fruits and vegetables (rose carnation and lotus). The shelf-life of two styles of flower from carved pumpkin did not exceed 6 days. Carved carrot in rose and carnation flowers had shelf-life for 12 days while radish was not more than 9 days. The shelf-life of rose and carnation carved cantaloupe did not exceed 9 and 6 days respectively. Lotus-carved Japanese cucumber had shelf-life for 6 days. Carved radish and Japanese cucumber were dipped in tap distilled water which had high initial microbial population that caused the short shelf-life. Thus the application of 2% calcium propionate and 80 mg/L peroxyacetic acid was the suitable treatment for reducing microbial population and improving the appearance quality and extended shelf-life.

The research on “A Study of Seasoning Watermelon shell Process ” had objectives of study to develop product of Watermelon shell jam from changing the prototype recipe of pineapple jam. The researchers altered the recipe by using Watermelon shell to replace 100 per cent pineapple texture in three recipes to be put additionally into water melon texture in three different content 20 per cent 30 per cent and 40 per cent of the total weight of Watermelon shell . The researcher studied about the process of making flavored Watermelon shell in order to study three types of appropriate and different processes of Watermelon shell including diced Watermelon shell chopped Watermelon shell and ground Watermelon shell in homogenous texture. From the study it was found that study of pineapple jam recipe was in prototype recipe; altering the recipe by using Watermelon shell to replace 100% pineapple texture. Then the researchers had tasting persons taste three basic recipes and found that tasting persons accepted recipe No. 2 in the total aspects of color scent flavor texture and fondness. The scores were 7.93?0.62 8.25?0.56 7.80?0.54 7.63?0.70 and 7.68?0.57 respectively; the fondness was from moderate level to much fondness. When variance was analyzed and statistical difference was searched it was found that total features of color scent flavor texture and fondness did not have significant difference at level of 0.05. From study it was found that study of process of making flavored Watermelon shell in three types including diced watermelon shell chopped watermelon shell and ground Watermelon shell in homogenous texture it was found that tasting persons accepted recipe No. 1 (diced Watermelon shell ) in total color scent flavor texture and fondness having mean value at 8.03?0.66 8.50?0.64 8.28?0.55 7.98?0.66 and 7.93?0.35 respectively in the level of moderate fondness to much fondness. When variance was analyzed and statistical difference was searched it was found that total features of color scent flavor texture and fondness had significant difference at level of 0.05.

The research studied results of integrated learning management in flower arrangement techniques subject of students from the bachelor’s degree in Home Economics Business Administration program Rajamangala University of Technology Phra Nakhon. The researchers provided the cooperative learning and selected three units of flower arrangement techniques subject consisting of materials and tools for arranging flowers creative flower arrangement and international flower arrangement. The research samples were the second year students of Home Economics Business Administration program. The research methods used in this study were a learning achievement form a satisfaction form and a participant observation form. Results of the study found were: 1. The effects of cooperative learning on students flower arrangement techniques subject achievement was found that there was a statistically significant difference between students pretest and post-test scores at the level .05. 2. The satisfaction of students toward flower arrangement techniques subject was at the highest level ( x = 4.00). It showed that students’ attitudes toward cooperative learning were at good level.
