The objectives of this research were to study the effect of hot air velocity on the changes of the moisture content and temperature of preserved tomatoes undergoing combined conveyor system and hot air drying. Specific energy consumption physical properties in term of color and shrinkage and sensory evaluation of dried preserved tomatoes were also investigated. The preserved cherry tomatoes were dried at a drying temperature of 80oc and hot air velocity of 2 and 4 m/s until the moisture contents of the preserved tomatoes were lower than 18% wet basis. The experimental results showed that the hot air velocity had effect on the changes of the moisture content and temperature of preserved tomatoes. Specific energy consumption total color difference shrinkage percentage and sensory evaluation results of dried preserved tomatoes of the hot air velocity of 2 and 4 m/s were not significantly different (P>0.05).Moreover the dried preserved tomatoes obtained from this research had significantly lower sensory scores in term of color and appearance than those obtained from the local market (P≤0.05). However sensory scores in term of flavor texture and overall preference of the dried preserved tomatoes obtained from this research and the local market were not significantly different (P>0.05).

Development of prototype products from waste rice for teenage consumer. The purpose of this study was developing formula and prototype of waste rice for food production. The waste rice could be used as rice in 100% for 3 products such as Khao Tang Rice Crackers and Sticky Rice Coconut Cream. The suitable condition for Khao Tang was using waste rice as 110 g. and seasoning 10%. The result of physical and chemical analysis showed that: products have orange bright color hardness cripyness and not rancidity. The percentage of moisture fat protein crude fiber ash and carbohydrate content 4.02 ± 0.06 20.12 ± 0.05 9.36 ± 0.04 2.58 ± 0.12 4.30 ± 0.11 and 59.62 ± 0.09 respective. The suitable condition for Rice Crackers was using waste rice as 130 g. storage in room temperature at 24 hr. After that place to microwave at 20 sec. %. The result of physical and chemical analysis showed that: products have orange bright color Tom Yum seasoning for delicious hardness cripyness and not rancidity. The percentage of moisture fat protein crude fiber ash and carbohydrate content 6.69 ± 0.03 1.65 ± 0.06 5.23 ± 0.07 0.93 ± 0.13 1.37 ± 0.08 and 84.12 ± 0.05 respective. The suitable condition for Sticky Rice Coconut Cream was using coconut milk (UHT) as 175 g. storage in freeze at 24 hr. After that place to microwave at 30 sec. %. The result of physical and chemical analysis showed that: products have white-yellow bright color softness and coconut sweet taste. The percentage of moisture fat protein crude fiber ash and carbohydrate content 43.55 ± 0.03 6.29 ± 0.02 3.21 ± 0.03 1.20 ± 0.06 0.50 ± 0.09 and 45.24 ± 0.05 respective. The shelf life of 3 products are more than 2 months and consumer acceptability like moderately product.

At the present the studies on the Mahachanok jam product is limited. The objective of this research was to study in the textural syneresis and sensory characteristics of Mahachanok jam from three types of geldings (pectin galactomannan and carrageenan) and different storage conditions (room temperature 4o C) for 1 month. It was found that the gel strength rupture strength and brittleness of the Mahachanok jam from carrageenan and galactomannan were higher than pectin (p≤0.05). When the jam was stored at 4oC jam from pectin had highest brittleness and jam from galactomannan had syneresis more than carrageenan and pectin (p≤0.05) respectively. The jam was stored at 4o C found that the syneresis was lower than stored at room temperature. For sensory evaluation the overall acceptance of Mahachanok jam from pectin and carrageenan were higher than galactomannan with the mean of like score between slight to moderate.

The purpose of this study was developing formula and prototype of mushroom in Moo Yaw chips for food production. The mushroom could be used as fat replacer in meat products 100%. The products have water holding capacity emulsion stability. The suitable condition for Moo Yaw chips as thickness of 1.5 mm. after that bake with oven at 60 ๐C 3 hours deep-fat-frying at 140 ๐C 3 second then bake with oven at 60 ๐C 15 mins and mix seasoning 10% for delicious. The result showed that physical and chemical analysis of Moo Yaw chips as follows : Hardness value 3.93 ± 0.22 N. Cripyness value 6.40 ± 2.70 aw value 0.33 ± 0.20 L* a* b* value 32.27± 0.82 18.29 ± 0.43 and 22.86 ± 1.57 respectively. Product have brown dark color. The percentage of moisture protein fat crude fiber ash and carbohydrate content 3.91 ±0.06 24.72 ± 0.06 29.53 ± 0.07 6.27 ± 0.17 7.80 ± 0.17 and 27.83 ± 0.17 respective. The proximate analysis of moisture content lees than formula control while protein content and ash content more than formula control. Moo Yaw chips have shelf life at least 2 months and consumer acceptability like moderately product.

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.
