USDA Updates FoodData Central With Watermelon Rind Information
The United States Department of Agriculture (USDA) recently finalized an official nutritional analysis for watermelon rind, providing standardized data for a part of the fruit that typically ends up in the compost bin. A one-third-cup serving of raw, seedless rind contains 10 calories, one gram of dietary fiber, 140 milligrams of potassium, and 4 milligrams of vitamin C. This formal recognition allows health professionals and nutritionists to offer consistent guidance on the potential benefits of the often-discarded portion.
Stephanie Barlow, senior director of communications for the Florida-based National Watermelon Promotion Board (NWPB), stated that this move addresses a significant knowledge gap. Most consumers remain unaware that the rind is edible. The NWPB funded the research and coordinated with the USDA to ensure the data reached the FoodData Central database. This provides an evidence-based resource that was previously missing from official government documentation.
Waste Reduction and Consumer Usage Trends
Watermelon consists of approximately 70 percent flesh and 30 percent rind. Data from the NWPB’s 2023 Watermelon Consumer Usage Study indicates that 62 percent of consumers discard the rind entirely. This behavior accounts for an average of five pounds of potential food waste per household consumption. While the rind lacks the sweetness of the inner fruit, it offers a functional way for home cooks to extract more value from their produce purchases.
Megan McKenna, the NWPB’s senior director of marketing and food service, emphasized the importance of using professional labs to verify the nutritional content. By standardizing these results, the organization aims to help both retail consumers and food service operators maximize their ingredients. Still, nutrition experts advise that the rind should not serve as a direct replacement for the nutrient-dense flesh, which remains the primary source of key antioxidants such as lycopene.
Practical Preparation and Safety Standards
Integrating watermelon rind into a diet requires specific preparation techniques. Lisa Young, a registered dietitian and adjunct professor at New York University, noted that the rind possesses a tougher texture than the interior fruit. Consumers should prioritize proper handling to ensure food safety. Washing the exterior of the whole melon under cool, running water before slicing is a non-negotiable step to prevent contamination.
Popular preparation methods include pickling, roasting, or shredding the rind for slaws. The outer green skin can be removed with a standard vegetable peeler, revealing a texture similar to a cucumber. Pickled rind can remain safe for consumption for up to two weeks when stored in a sealed glass jar in the refrigerator. Freshly cut watermelon, when kept in a proper container, maintains quality for three to five days. As households seek to lower grocery expenses, these methods provide a straightforward pathway to extending the utility of summer produce. The growing trend of online content creators showcasing international recipes has also pushed public interest in using the entire fruit further than it has reached in previous years.
