Red Onion
Product Overview
Red onion is a popular onion variety valued for its vibrant purple-red skin, crisp texture, and mildly sweet flavor. It is widely used in retail, food service, and food processing sectors and is especially popular in fresh preparations where its color and flavor enhance visual appeal and taste.
Key Characteristics
Red onions are medium to large-sized bulbs with deep red to purple outer skin and white flesh accented by reddish-purple rings. They have a crisp texture and a mildly pungent, slightly sweet flavor. Red onions are commonly consumed both raw and cooked and are non-climacteric, meaning they do not continue to ripen after harvest.
Nutritional Value
Red onions are low in calories and provide vitamin C, dietary fiber, folate, and potassium. They are also rich in antioxidants, particularly anthocyanins, which give them their characteristic red-purple coloration.
Seasonality and Origin
Red onions are grown in temperate and subtropical regions and are available year-round through production and storage programs. Major producing countries include the United States, Mexico, India, China, and Spain.
