Vegetables.
Waxing is a premarketing operation used for vegetables such as cucumbers, potatoes, sweet potatoes, and tomatoes to enhance their marketability and shelf life. This process serves two primary purposes:
- Aesthetic Appeal: It gives the produce a bright, attractive appearance for consumers.1
- Moisture Retention: It helps control shriveling by reducing the rate of moisture loss from the vegetable.1
By applying a thin layer of wax, producers can maintain the quality of these vegetables during storage and transport.1
