The purpose of this research was to study the dyeing polyamide/elastane fabric with natural indigo using exhaustion dyeing process. The effects from the concentration of the natural indigo dye thiourea dioxide and sodium hydroxide were investigated. The colour of each dyed material was investigated in term of the CIELAB (L* a* and b*) and K/S value. The color fastness to washing rubbing perspirdation light water sea water and chlorinated water of the dyed samples was determined. The bursting strengrh of dyed polyamide/elastane was evaluated. The best vatting condition was at 50 ̊C for 30 minutes. The optimal formula of dyeing polyamide/elastane fabric using natural indigo was prepared by mixing 200 g/L natural indigo paste 60 g/L thiourea dioxide 1 g/L sodium hydroxide. The fabric dyed in the solution of indigo vatting a shade of dark blue colour. The color fastness to light washing water sea water perspiration and chlorinated water were good to very good. However the rubbing fastness results showed fair level. The bursting strength of dyed fabrics is less than the undyed fabric 3.1%. The optimal ratio of discharge printing on polyamide/elastane fabric were compose of 70 % starch print paste and 30 % discharging agent (KMnO4). The pattern design produced from these combinations in the printing areas on fabrics showed an excellent standard of printing quality. The results confirmed that natural indigo dyes have potential applications in polyamide/elastane fabric dyeing and the dyed fabric can be used produce women’s intimate apparel.

The objective of this research was to find the suitable processes of carved-vegetables which packed in hermetically sealed container. Two vegetables were composed of carrot and pumpkin. There were carved into rose or leaf shape. An optimum ratio of 2 recipes of pickle solution were studied. The first one was a recipe which acidified with lactic acid (acidified-recipe) to pH <4.6. Another one was a recipe supplemented with preservative (preservative-added recipe). The results showed that an optimum ratio for acidified-recipe was composed of 7.23% vinegar 64.81% water 0.81% salt 27.00% sugar and 0.15% lactic acid which showed the final pH was 3.27. For preservative-added recipe an optimum ratio was composed of 27.03% vinegar 27.03% water 0.9% salt 45.05% sugar and 200 ppm sodium metabisulfite which showed the final pH was 3.39. Carrot pumpkin green papaya and cucumber were sanitized in peroxyacetic acid (80 mg/L 3 min). Radish was dipped in tap water for 3 min. Then all carved-vegetables were immersed in calcium chloride solution (0.5% 2 min) before preserved in acidified-recipe solution in plastic box with a lid and then stored at room temperature for 4 days. Equilibrium time pH and °Brix were studied. The results showed that pH and °Brix were decrease during 4 days storage and showed obviously tended to equilibrium. However carved-radish and cucumber were spoiled by microorganisms as a film on the surface of pickle solution and gas bubble was occurred inside a container on 4 days of the storage. Hence three carved-vegetables including carrot pumpkin and radish were used in the next experiment which preserved in preservative-added recipe. Treatment was compared with the same recipe without preservative as the control. All types of carved-vegetables had an equilibrium time for 7 days. Three parts of samples e.g. pickle solution carved-vegetables and mixed-sample showed pH lower than 4.6 and °Brix were gradually decreased during the storage. Shelf-life of all carved-vegetables stored in hermetically sealed container was up to 7 days. Total bacteria count E. coli yeast-mold were not exceeded than the standard limited by Ministry of Public Health and Staphylococcus aureus was not detected throughout 7 days of the storage.

Suitable durian rind flour production (durian rind flour-DRF) was three strain different durian rind were used include Chanee (CN) Monthong (MT) and Kan Yao (KY). Three methods of durian rind were used. 1 (TD-Tray Dry) 2 (SD-Stream Dry) and 3 (BD-Boil Dry). Chanee Monthong and Kan Yao Durian rind after drying and powdered process was found drying method 2 (SD-Stream Dry) to the highest yield of durian rind Kan Yao the second and the lowest durian rind is Monthong. The total weigh strain and shelf life of durian was affect to durian rind powder volume. Kan Yao is high volume of the white rind the second is Chanee and Monthong is lowest in white rind. The most total weigh of durian was affect to white durian rind in the other hand durian low total weigh was affect to white durian rind to the durian rind powder. Crude fiber is the mainly of chemical compositions of the three strain different durian rind. Cellulose and lignin as non-soluble dietary fiber. The soluble fiber found in durian rind is pectin. The quality of durian rind powder in Method 2 gave the lightest color followed by Method 3 for Method 1 to give the darkness color. Acidity of durian peel and durian rind powder acidic. The viscosity of durian rind is derived from pectin-a polysaccharide compound. For the communication of technology the potential development of durian rind flour powder at the Faculty of Home Economics Technology the participants were most satisfied in all aspects. Preparation of durian peel powder in all 3 ways there are parts that can not be powdered. In the next study. It is recommended to study the method to obtain powdered durian that cannot be powdered.
