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.

Study about duck cream soup product from waste duck ribs had objectives to study production process of duck cream soup product and to study about chemical and physical quality of duck cream soup product. The procedures in operation are as follows: Study about three basic recipes of duck cream soup product and study about appropriate time period in boiling of duck rib stock for producing of duck cream soup. The duck rib stock obtained from boiling in different three levels of time as follows: 2 3 and 4 hours. After that the researcher tested in sensory test in overall appearance color smell flavor texture and favor. The researcher used method of giving points of 9-point Hedonic scale. There were 40 testing persons. The researcher planned the random test in RCBD: (Randomplete block design) and compare difference of mean by DMRT (Duncan’s New Multiple Range Test). From the study result it was found that basic recipe cream soup which has been accepted the most of all was Recipe No.2. It was found that the researcher did not give different points to overall appearance color smell and favor. The mean was 7.10 7.23 7.10 and 7.48 respectively. The Duck rid stock obtained from boiling in different three levels of time as follows: 2 3 and 4 hours. Duck cream soup using duck stock for a period of 4 hours Because of the boiling simmer for a long time. Cause evaporation of water As a result the concentration and the smell more pronounced. The mean was 7.18 7.15 7.10 and 7.33 respectively result of chemical and physical quality analysis included viscosity cream soup duck that the period of boiling for 4 hours of 2 .7 5 x 103 cestipois the most pH value to be 6.12. This is consistent with generally produce only soup. The viscosity is between 103 to 104 which the retrogradation of the roux. The duck cream soup with and good texture.

The purpose of this research was the use of jaggery palm substitute partial sugar in Khanom Chan the suitable ratio of jaggery and sugar (25:50 50:50 and 75:25) were investigated and to study the suitable kneading time which varied at 5 1015 and 20 minutes. Analyze nutritional values and design the experimental by Randomized Complete Block Design (RCBD). Sensory evaluation (color flavor taste texture and overall liking) was tasted by sixty testers with 9-point hedonic scale. After that using 5-point hedonic scale for consumer acceptance test by one-hundred testers. Results showed that the suitable ratio is 50:50 and the suitable kneading time is 20 minutes had high score in every attributes from sensory test. Chemical properties protein fat ash and moisture content were increased while carbohydrate total energy and energy from fat were decrease that compared with basic recipe of Khanom Chan. The partial substitution of sugar with jaggery palm that still yielded an acceptable product for the consumers was 100%.

Food is one of the four basic human needs. Now an increase in the amount of restaurant business has affected the household food consumption behaviour; consumers are buying more ready-to-eat food products. The behaviour increases the risks of consuming contaminated food so the cleanliness and the safety of the nourishment should be seriously taken care. Restaurant Development Way for Food Safety A Case Study: Savoey Restaurant Tha Maharaj Branch was aimed to study practice plans associated with applying knowledge on food safety; to survey understanding on food safety practice; to study factors affecting food safety development of Savoey Restaurant Tha Maharaj Branch. The population and sampale of this study comprised totaled 20 employees qualified for specifications set by the researchers. The tools included content analysis and weighted arithmetic mean mean percentage and standard deviation were employed for statistical analysis. The findings indicated there were two workflow operations of Savoey Restaurant Tha Maharaj branch; Service workflow operation Kitchen and bar workflow operation. The inspections of food hygiene standards in 9 aspects were conducted by researchers. The marks were given associated with the criteria of the List of Food and Drug Administration No 840/2545 attached to the Assessment Methods for Inspection Results of Food Manufacturer under the Ministerial Notification that overall mark of each topic must not lower than 50 percent and no serious defects were found. The Savoey Restaurant Tha Maharaj Branch meets the specified criteria in six aspects comprising dining area with air-conditioners (65.46 percent) outdoor dining area and vicinity (56.82 percent) machine utensils and equipment (87.5 percent) maintenance and cleaning (55 percent) wastewater and waste treatment (58.33 percent) cleanliness and convenience of restrooms (62.5 percent). Each topic meets the criteria on general hygiene standard control. Meanwhile the topics required immediate correction were food preparation and cooking area (27.6 percent) followed by personal hygiene (40.83 percent) and quality control of food ice cube and beverage (49.17 percent) respectively. Thus it is concluded that the current problems arising out of inadequate understanding on good practice of food safety since the business owner has never provided trainings on hygiene for their workers.

The objectives of this study is to 1) study the behaviors of consumption of baked goods in Bangkhen district Bangkok and 2) study factors of decision making of consumers on services. We have sample of 400 subjects and used statistical methods consist of frequency proportion mean standard deviation t-test and F-test. From the results we found that most of the consumers are female of age between 20 – 30. Most of our samples are students and have income less than 10000 baht per month. For the results on behaviors we found that most purchases are for self-consumption. Cakes are the most popular baked goods. There’re 1 – 3 quantity of goods per purchase and cost around 70 -150 baht. The frequency that samples go to bakery is 1 – 4 times a week from Monday to Friday and around 15.01 – 19.00. Samples mostly got information of bakery from personal communication. The results show that price is the most important factors influence on consideration of consumers given ( = 4.46) of mean. While other important factors are products ( = 4.37) convenience ( = 4.10) brand loyalism ( = 4.05) commercial ( = 3.99) brand’s quality ( = 3.96) and brand ( = 3.85). There’s no difference on the influence of gender on consumption but there’s a significant difference between price and brand’s quality and between ages and between convenience and commercial.
