Final answer:
Wholesalers and retailers can preserve the freshness of products by using preservatives and proper storage conditions.
Step-by-step explanation:
To preserve the freshness of products, wholesalers and retailers can take several measures. First, they can use preservatives such as antioxidants to slow down spoilage caused by bacteria, molds, fungi, or yeast. These preservatives can also prevent changes in color, flavor, or texture and delay rancidity. Another way to preserve freshness is by using refrigerated and well-ventilated storage facilities for fruits and vegetables. These conditions help maintain the quality and safety of the products.
