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.

The replacement of partial sugar with jaggery palm in Khanom Ar-Lua production was further carried out for studying the suitable ratio of jaggery and sugar are 25:50 50:50 and 75:25 and studying the suitable drying time which varied period of time at 8 9 10 and 11 hours. Analyze nutritional values of Khanom Ar-Lua that sugar partially replaced with jaggery palm and Randomized Complete Block Design (RCBD) was applied. Sensory evaluation (color flavor taste texture and overall liking) was tasted by sixty panels with 9-point hedonic scale. After that using 5-point hedonic scale for consumer acceptance test by one-hundred panels. The results showed that Khanom Ar-Lua which use of jaggery palm replacement partial sugar at ratio of 25:75 had the highest score in every properties of sensory test. The suitable drying time is 10 hours. Khanom Ar-Lua that used jaggery palm to replace partial sugar had higher protein carbohydrate and total energy than basic recipe but moisture content and energy from fat are the lower. The consumer acceptance test showed that 99% acceped Khanom Ar-Lua which using jaggery palm replaced patial sugar.

The study on baked crispy okra sheets (Hit 9701 species) by using a hot air dryer. The objective of this study was to investigate the okra sheets formula and manufacturing procees by hot air dryers with 3 methods; pouring finely blended okra onto the inside tray pouring finely blended okra onto the outside tray and pouring finely blended okra into an aluminum block. It was found that pouring finely blended okra into an aluminum block resulted in the least crack in the dried sheet with the rectangular shape remaining intact. After the forming method is decided on a study was conducted on the temperature to bake okra at 3 levels namely 70 80 and 90 C.It was found that baking okra at 80 C for 4.5 hours was suitable the baking and crispy okra sheets ended up with the lightness(L*) of 49.75 the green (a*) was-2.53 and yellowness (b*) of 23.71. The moisture content was at 5.07 % water activity content was 0.27 The hardness was 5.01 N and the crispness was 4.67. The results of chemical analysis showed that the carbohydrate content was 76.34% crude fibers was 10.72% ash content was 8.24% moisture content was 4.24% and fat content was 0.46%. From the study on the bacteriological quality it was found that the crispy okra sheet products can be stored at room temperature for 28 days.
