When purchasing dried fruits such as dried apples, opt for pre-packaged products rather than loose, bulk items whenever possible. Check the packaging to ensure it displays the required information, such as the product name, place of origin, manufacturer's name, production date, batch or code number, specifications, shelf life, and consumption instructions. Prioritize products from well-known, large-scale enterprises known for good product and service quality. Additionally, after opening the package, smell the product; a pungent, off-putting odor may indicate high levels of residual sulfur dioxide. You can thoroughly soak the product in clean water to help reduce potential health risks before consumption.
