The study of vegetable-carved processing packed in hermetically sealed container for 5 types of plant e.g. carrot pumpkin radish green papaya and cucumber which carved into rose or leave shape and preserved in acidified-pickle (7.23% vinegar 64.81% water 0.81% salt 27.00% sugar and 0.15% lactic acid pH 3.27). The processing were conducted by sanitized carved-carrot pumpkin and radish in peroxyacetic acid solution (80 mg/l 3 min) or dipped in tap water (3 min) for green papaya and cucumber. Then all carved-vegetables were blanched in calcium chloride solution (0.5% 3 min) followed by preserved in acidified-pickle in plastic box with a lid and stored for 4 days at room temperature (25ºC). The results showed that pH and °Brix decreased 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 4th days of the storage. Hence carrot and pumpkin were used in the next experiment which preserved in preservative-added recipe (27.03% vinegar 27.03% water 0.9% salt 45.05% sugar and 200 ppm sodium metabisulfite pH 3.39) with hot-filled method in glass bottle. Treatment was compared with carved-vegetables preserved in acidified-pickle and kept at 4oC as the control. The pH of samples of pickle solution carved-vegetables and mixed-sample of both treatments showed lower than 4.6 and °Brix were gradually decreased during storage periods.The appearance of both treatments were maintain good and not different between treatments. Shelf-life of carved-carrot -pumpkin and -radish stored in hermetically sealed container was up to 7 days. Total bacteria count Escherichia coli yeast-molds were not exceeded than the standard limited by Ministry of Public Health and Staphylococcus aureus was not detected

Tis research had the following objectives to study 1 production of crispy baked fibrous covering jackfruit meat 2 production of snack from crispy baked fibrous covering jackfruit meat 3 acceptance of snack made from crispy baked fibrous covering jackfruit meat by evaluators 4 storage time of smack product in room temperature. When fibrous covering jackfruit meat when baked at 70 80 and 90 degrees Celsius for 100 minutes evaluators accepted snack baked at 90 degrees Celsius by the best all around score at statistically difference (p ≤0.05). ln studying sweetness by using three levels of sugar at 50 60 and 70 grams. Products with 60 and 70 grams of sugar received same score. The amount of sugar at 60 grams was used. ln studying Amount of fibrous covering jackfruit meat at 20 25 and 30 gram iT was found that 25 Grams of fibrous covering jackfruit meat received the highest score. ln forming the shape of the snack the use of only fibrous covering jackfruit meat could not be formed into any shape. Pressed rice ba-sae and pressed rice were used. The pressed rice helped ingredients formed into shape. The temperature used in baking the product at 70 80 and 90 degrees Celsius were used. The higher temperature lessened time of baking. 90 degrees Celsius were used to bake the snack for 20 minutes. This product was accepted by evaluators at acceptance test using differences at statistically difference (p ≤ 0.05). when studied storage time by keeping product 2-4 weeks at room temperature vacuum packed. Free water and the yeast and mold amount wrer tested every 10 days. During 0 to 16 days no yeast and mold wrer found. The moisture level was 0.58. On the 17 th day mold count increased to 700 (CFU/g) and the moisture content increased. Therefore fibrous covering jackfruit meat product can be kept 16 days.

Khao’ Niao Dam is a grain which has anthocyanins pigment. Rice flours contained high protein content more than white grain and have higher water absorption. The white rice flour had higher swelling power and lower solubility than 6 rices flours. Amylose which content in the white rice flour is peak viscosity final viscosity setback and pasting temperature than the waxy rice flours. The objectives of this research were to formulate and determine the appropriate condition for sensory test on the rices powdered beverage products to consumers in terms of color flavor sweet taste viscosity and preference overall. Starting from the basic formula 3 formula is a formula that consists of Germinated brown rice drying were 23.33 % millet drying were 3.33% soybean powder were 6.67% powdered milk were 13.33% sugar were 33.33 % and cream powder were 20.00%. Acceptance scores of 7.60 and then to research the use of Germinated brown rice drying a substitute for cream powder in the manufacture of rice powder beverages into 3 levels such as 50 75 and 100% the amount of Germinated brown rice drying a substitute for cream powder 100 % has been the most acceptance. Then the ratio of rice flour 7 the appropriate type of beverage rice powdodor and viscosity of the beverage rice powder for 3 formulas were formulated with Black Glutinous flour were 10.00% the most acceptance. The study of soybean powder substitute millet powder in the manufacture of rice powder beverages to reduce the viscosity into 3 levels: 50 75 and 100%. The result showed that the suitable of soybean powder substitute millet powder were 100% and the most acceptance. This study used amount of soybean powder and milk powder substitutes sugar in the production of powdered rice beverage can be divided into 3 levels in the formula is 5 10 and 15% the result showed that the 10% of the soybean powder and 15% of milk powder substitutes sugar the most acceptance. Then study the temperature of water for rice powder beverages and the ratio of water to the rice powder beverages in the rice powder is 1:5. Nutritional value analysis of rice beverage product showed were 6.46% moisture 11.63% protein 7.34% fat 5.65% dietary fiber 1.47% ash and 67.45% carbohydrate and the shelf-life of rices powdered beverages which pack in aluminum foil bags was preserve products and store at 30 °C more than 6 weeks.

This research focuses on the production of charcoal briquettes from agricultural residues by using durian and nypa palm peel mixtures. The objectives of this study are to study the combustion efficiency of charcoal briquettes; study the suitable ratio for the production of briquettes with the ratios of durian : nypa palm peel mixtures as 100:0 50:50 25:75 and 0:100; recycle the agricultural residues as the renewable energy sources and analyze the fuel characteristics; moisture content ash content volatile matters fixed carbon and heating value. The results showed that the best ratio for the combustion efficiency of charcoal briquettes is 50:50 with the minimum moisture content of 4.68% the minimum ash content of 2.70% the volatile matters of 10.33% ; the maximum fixed carbon of 25.56% and all characteristics are met with the standard of charcoal briquettes from the local community products. In the ratio of 100:0 it showed the maximum heating value as 5399 calories per gram. Therefore the 50:50 charcoal briquettes are suitable as the renewable energy source. Besides the capacity of odor adsorption was analyzed by adding the odor substances (mothball) in two bottles with three mothballs for each bottle for two consecutive days before removal. Then sic of 50:50 charcoal briquettes were added into one bottle. Ten testers smelled the bottle every two days for six days. The result showed that the bottle with the charcoal briquettes had odor less than the bottle without briquettes. Hence the charcoal briquettes from durian and nyla palm peel mixtures have the best odor adsorption capacity and are suitable for household uses.
