master-cooks | Why Grocery Store Apples Have That Thin Layer Of Wax

Grocery store apples often have a thin layer of wax applied to their surface, which serves multiple purposes. Firstly, this wax coating helps to preserve the freshness of the apples during transportation and storage. Apples naturally produce their own wax, which acts as a barrier to retain moisture and maintain firmness. However, during the cleaning and packing process, this natural wax can be removed. To compensate, a small amount of food-grade wax is applied to apples. This added wax not only helps in moisture retention but also provides a glossy appearance, enhancing the fruit's visual appeal and making it more attractive to consumers. Moreover, the wax coating acts as a protective layer, reducing the risk of bruising and damage during handling and transit. This is particularly important for maintaining the quality and shelf life of apples as they make their way from orchards to grocery store shelves. The wax used is safe for consumption and is approved by regulatory bodies, such as the U.S. Food and Drug Administration. Common types of wax used include carnauba, shellac, and beeswax, all of which are derived from natural sources. Overall, the wax coating is a practical solution that benefits both the fruit and the consumer by ensuring apples remain fresh, appealing, and protected.

The wax extends the shelf life of apples

Apples, which are primarily made up of water, naturally develop a waxy layer to help retain moisture and avoid drying out. This natural wax is also present on other fruits such as lemons, oranges, and pears, even when they are freshly harvested. The wax serves as a barrier against pests and fungi, preventing them from penetrating the apple's flesh. However, after apples are picked and prepared for transport to grocery stores and supermarkets, they undergo a comprehensive cleaning process that removes this wax, along with any dirt or bacteria that may have accumulated during harvesting.

Once the natural wax is removed, a new layer is applied to help the apple retain moisture. This wax layer usually consists of natural carnauba wax and various food-grade synthetic waxes. In addition to aiding moisture retention, this wax creates a protective barrier that prevents bacteria and other contaminants from entering through any small cuts in the apple's skin. While one of the wax's functions is to extend the apple's shelf life, it also improves the fruit's appearance, giving it a shiny, fresh look that is more attractive to consumers.

Should you remove the wax?

The wax applied to apples and other fruits is composed of natural or food-safe substances and is designed to be safe for eating. There's no need to painstakingly remove all the wax from an apple before enjoying it. However, as with all grocery store produce, it's a good idea to rinse your apple to eliminate any dirt that may have accumulated (just be sure to wait until you're ready to eat them, as washing can reduce their shelf life). The FDA recommends against using soap or specialized produce washes on apples, as these chemicals can seep through the skin and potentially lead to health issues. Instead, simply use a soft-bristled brush to gently clean the apple, and you’re all set.

Apples are a wonderful and tasty addition to any diet. While their waxy exterior may not look appealing, it serves to protect the apples for safe consumption, so there's no need for concern before you enjoy one.
