Longan is the important economic crops of the region. But the longan be kept short and not easy by the factory where DS food which contains business processing agricultural crops by the production of dried longan. The oven are limited.The factory in longan longan fruit fresh wait in baking process have nectar flow. When and dried, sell at a low price. Therefore, the objective of this research project.The longan after through extending the also the quality is acceptable. The way to extend the longan. Be made by soaking in solution the longan shell. This research, therefore, design of experiment of full factorial 2K.The study 3 factors including temperature, ratio of longan to solution and bags, all 4 repeated experiment is to find the most appropriate response The color value of longan should are minimized. Soluble solids (sweet).And pH greater than 5 up
.The results showed that the factors affecting the result of longan color significantly, including factors AB is interaction between temperature and the ratio of longan on the solution. And the factors affecting the total soluble solidThe A factor is temperature.The factors C's bag, and the factors BC is interaction between longan to solution ratio and bags. The equations to calculate the appropriate conditions for the model finally. From the processing program, MNITABThe color of the longan was 4.5425 and the yield of soluble solids (sweet) was 19.7450 oBrix which a reasonable level of each factor is the temperature 5 degrees Celsius. The ratio of longan to solution 1:1 and bags coated (Al / PE). The experimental results confirmed by repeated experiments and the test results were compared with average value of fresh longan from previous research. It was found that the mean in experiments confirm the results are close to the equation.7 days and make the longan after process extend quality acceptable
.Then, in section of Engineering Economics If the way to extend this fresh longan to use. Must cost increase, 825.45 080 1, respectively. But it will make the income has increased, 1, 355 230.55 baht since can be sold in 38 price per kilogram. So it is essential that worth investing
