A fresh-keeping box is a container designed to preserve the freshness of food for a longer period. These boxes are typically airtight and made from materials like plastic, glass, or stainless steel. They help maintain the quality, flavor, and nutritional value of food by reducing exposure to air, moisture, and contaminants. Fresh-keeping boxes are ideal for storing fruits, vegetables, leftovers, or even meal prep items. They come in various sizes and shapes, making them convenient for different storage needs. Some are also microwave-safe or freezer-friendly, adding to their versatility. Using these boxes can minimize food waste and keep your kitchen organized.
