Engineering Laboratory for Agro-processing and Safety Control of Jiangxi Development and Reform Commission, Jiangxi Agricultural University, Nanchang , China) ABSTRACT: Objective To compare and analyze the moisture detection methods of sunflower seeds and pumpkin seeds. Methods To determine drying conditions will lead to the difference of results by using 105 constant weight method and 130 timing and constant temperature drying method to test moisture constant of sunflower seeds and pumpkin seeds in different pretreatment conditions. Sunflower seeds and pumpkin seeds were measured by 130 timing and constant temperature drying method for 10 times to analyze whether there were significant differences in moisture result in different samples under the different pretreatment methods and the same drying conditions. Results The method of using whole seeds grinding method to treat sunflower seeds and pumpkin seeds then drying by 130 timing and constant temperature drying was closer to the real value. Conclusion In consideration of fast and accurate processing, we recommend using 130 timing and constant temperature drying method with mechanic grinder for whole shredded method to detect the moisture of sunflower seeds and pumpkin seeds.
