In this work, a storage study was conducted to find suitable packaging material for tomato powder storage. Experiments were laid out in a single factor completely randomized design (CRD) to study the effect of packaging materials on lycopene, vitamin C moisture content, and water activity of tomato powder; The factor (packaging materials) has three levels (low-density polyethylene bag, polypropylene bottle, wrapped with aluminum foils, and packed in low-density polyethylene bag) and is replicated three times. During the study, a twin layer solar tunnel dried tomato slices of var. Galilea was used. The dried tomato slices were then ground and packed (40 g each) in the packaging materials and stored at room temperature. Samples were drawn from the packages at 2-month interval for quality analysis and SAS (version 9.2) software was used for statistical analysis. From the result, higher retention of lycopene (80.13%) and vitamin C (49.32%) and a nonsignificant increase in moisture content and water activity were observed for tomato powder packed in polypropylene bottles after 6 months of storage. For low-density polyethylene packed samples and samples wrapped with aluminum foil and packed in a low-density polyethylene bag, 57.06% and 60.45% lycopene retention and 42.9% and 49.23% Vitamin C retention were observed, respectively, after 6 months of storage. Considering the results found, it can be concluded that lycopene and vitamin C content of twin layer solar tunnel dried tomato powder can be preserved at ambient temperature storage by packing in a polypropylene bottle with a safe range of moisture content and water activity levels for 6 months.

包装材料对干番茄（Lycopersicon esculentum Mill.）粉贮藏期间番茄红素、维生素C和水分活度的影响
在这项工作中，进行了一项储存研究，以寻找适合番茄粉储存的包装材料。采用单因素完全随机设计（CRD）进行实验，研究包装材料对番茄红素、维生素 C 水分含量和番茄粉水分活度的影响；因子（包装材料）分为三个级别（低密度聚乙烯袋、聚丙烯瓶、铝箔包裹、低密度聚乙烯袋包装），重复3次。在研究过程中，双层太阳能隧道干燥了 var. 番茄片。使用了加利利。然后将干燥的番茄片研磨并装入包装材料中（每片40克）并在室温下保存。每隔2个月从包装中抽取样品进行质量分析，并使用SAS（9.2版）软件进行统计分析。结果表明，聚丙烯瓶装番茄粉储存6个月后，番茄红素（80.13%）和维生素C（49.32%）保留率较高，水分含量和水分活度没有显着增加。对于低密度聚乙烯包装样品和用铝箔包裹并装入低密度聚乙烯袋中的样品，储存6个月后，番茄红素保留率分别为57.06%和60.45%，维生素C保留率分别为42.9%和49.23%。考虑到结果，可以得出结论，双层日光隧道干燥番茄粉的番茄红素和维生素 C 含量可以通过包装在水分含量和水分活度水平安全范围的聚丙烯瓶中在环境温度下保存 6 个月。
