Bagged salad is often a source of food waste in many households due to spoilage. To combat this, food experts recommend a simple trick: placing a dry paper towel inside the bag or container with the greens. This absorbs excess moisture, which is a key factor in spoilage. According to the U.S. Department of Agriculture, bagged greens should be kept at a temperature of no more than 41°F (5°C) to maintain freshness. It is also advisable not to rinse pre-washed salads before storage, as this can introduce additional moisture. Discarding any wilting leaves promptly can further help maintain the quality of the remaining greens. By implementing these storage techniques, households can significantly reduce food waste and save money, making the practice of using a paper towel in salad bags both economical and environmentally friendly.
