This research aimed to investigate the suitable method to product osmotically dehydrated banana peels and determine its shelf life as well as consumer acceptation. It was found that the proper method was the slow osmotic dehydration process with 30 40 and 50% of syrup (sucrose solution). This method led to the highest appearance color and flavor scores as accessed by the consumer. Therefore the slow osmotic dehydration process was selected for further study relating to the ratio between salt and malic acid (3:2 3:3 and 2:3 of syrup weight). The result show that no differences in appearance color flavor and texture scores were found among treatments however the sample treated with salt and malic acid in the ratio of 3:3 obtained the highest taste score. Thus the suitable process to produce the osmotically dehydrated banana peels was slow process with salt and malic in the ratio 3:3. According to the shelf life study the sample (100g) packed in metallic foil still compiled with Thai community standard of fruit and vegetable products during 12 weeks of storage under 25-30 °C. In addition the consumers also accepted the selected osmotically banana peel product.

The research was aimed to: 1) create a standard formula of Sangyod brown-rice flour Thai Lodchong 2) study the change during storage and 3) study the consumers’ acceptance. The physical properties chemical composition sensory evaluation and microbiological quality were determined. The study showed that Lodchong in which the substitution of Sangyod brown rice flour at 50% by weight of rice flour and 30% of arowroot flour for the total flour weight were used was most accepted in all aspects. The product has a slight physical conversion at 7 °C for not longer than 48 hours. All the microorganisms yeast and mold found were still safe for consumers and none of Escherichia coli was detected in the product. Nutritional analysis results revealed that 100 grams of the product contained 78.64 kcal energy 0.98 g protein0.07 g fat 18.03 g carbohydrate dietary fiber 0.71 g and 11.63 mg anthocyanin. For consumers’ acceptance it was found that the product was much accepted and 99% of the consumers were interested to buy the product at 22 bath per 180 ml cup.

The purposes of this research were developing for health Thai custard dessert (Khanom Maw Kaeng) by using the Jerusalem artichoke powder and cereal cream instead of coconut cream. By using Jerusalem artichoke powder 3 types and 3 levels at 2 % 4 % and 6% the result of sensory evaluation from 40 nutrition experts had showed that using Jerusalem artichoke powder at 2% and 4% had been no significant difference at P<.05. The testing of custard with 4% of Jerusalem artichoke powder was receiving the result from a hundred consumers by the overall liking test using 9-point hedonic scale a hundred consumers rated the products like moderately to very and 100% of consumers accepted the product. Hardness of product was being 319.72 firmness was being 230.83 cohesiveness was being 0.17 and difficulty of crunch was being 24.85. The result of a physical attributes; the facial color was being bright at L* 37.13 the color value of green to red was being a* 8.27 and blue to yellow was being b* 12.15. But the color of product was being bright at L* 46.52 the color value of green to red at a* 5.06 and blue to yellow at b* 14.34 and the results of chemical factor were being; relative humidity was being 37.71 protein was being 14.36 fat 3.21 Ash 0.79 dietary fiber 3.23 total dissolved solid was being 33.27 carbohydrate was being 40.70 and total energy was being 249.13 respectively.

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

The purposes of this research are to investigate 1) personal factors contributing to the longevity of elderly 2) the dietary behavior of long-living elderly and 3) the relationship between personal factors such as:gender age BMI and dietary behavior. The samples are 29 of long-living elderly with ages more than 80 years old living in Tambon Tha Phi Liang Muang district Suphanburi province. The long-living elderly must be able to answer the questions. The statistics used to analyze data in this research are frequency percentage and Chi-Square (χ2). The data were analyzed using statistical tools. As for thier dietary behavior it was found that most long-living elderly usually have five food groups:eggs UHT milk paddy morning glory cabbage watermelon papaya and vegetable oils. They purchased these five groups of food for consumption. Boiling was the main method of cooking. They usually stored food in the refrigerator to keep them fresh. The relationship between personal factors and dietary behavior could be classified into 5 areas : types of food frequency of consumption sources of food methods of cooking and methods of food preservation. The finding found that gender age and BMI were related with food consumption. However cooking (boiling) was not related with statistically significant level at .05.
