快速微波水分仪在测定果蔬罐头水分中的应用
目的 建立用快速微波水分仪测定果蔬罐头中水分的方法。方法 在微波条件下对水分含量高的果蔬罐头进行检测, 寻找出测定果蔬罐头水分的最佳条件, 检测结果和GB 5009.3-2016《食品安全国家标准 食品中水分的测定》直接干燥法检测结果进行比对。结果 本方法检测果蔬罐头, 样品搅拌均匀下, 均匀涂抹到样品垫上的厚度<4 mm, 所测定的水分含量结果相对标准偏差(relative standard deviation, RSD)值理想, 结果再进行F检验计算和t检验计算, 所检测结果与直接干燥法检测结果也无显著性差异, 结果重现性好、耗时少, 能满足快速分析的要求。结论 本方法可等效标准检测方法使用, 适用于果蔬罐头水分的批量检测。
Objective To establish a method for the determination of moisture in canned fruits and vegetables by rapid microwave moisture analyzer. Methods Under the microwave condition, the canned fruits and vegetables with high moisture content were detected, and the best conditions for the determination of the moisture content in the canned fruits and vegetables were obtained. The results were compared with the results of direct drying method in the GB 5009.3-2016 National standard of food safety-Determination of moisture in foods. Results When the sample was mixed evenly, the thickness of the sample was less than 4 mm, and the relative standard deviation (RSD) value of the moisture content was ideal. The results were calculated by F test and t test, and there was no significant difference between the results of this method and that of direct drying method. The results had good reproducibility, less time consuming and could meet the requirements of rapid analysis. Conclusion This method can be used as an equivalent standard method for the batch detection of water in canned fruits and vegetables.
