Sunflower seed
Summary
Sunflower seed are the seeds of the sunflower (Helianthus annuus). There are three types of commonly used sunflower seeds: linoleic (most common), high oleic, and sunflower oil seeds. Each variety has its own unique levels of monounsaturated, saturated, and polyunsaturated fats. The information in this article refers mainly to the linoleic variety.
For commercial purposes, sunflower seeds are usually classified by the pattern on their husks. If the husk is solid black, the seeds are called black oil sunflower seeds. The crops may be referred to as oilseed sunflower crops. These seeds are usually pressed to extract their oil. Striped sunflower seeds are primarily eaten as a snack food; as a result, they may be called confectionery sunflower seeds.
The term "sunflower seed" is actually a misnomer when applied to the seed in its pericarp (hull). Botanically speaking, it is a cypsela. When dehulled, the edible remainder is called the sunflower kernel or heart.
In 2020, global production of sunflower seeds added up to 50 million tonnes, led by Russia and Ukraine with 53% of the world total combined (table). Argentina, China, and Romania also contributed significant volumes.
Sunflower are commonly eaten as a snack, but can also be consumed as part of a meal. They can be used as garnishes or ingredients in various recipes. The seeds may be sold as in-shell seeds or dehulled kernels or be sprouted and eaten in salads.
When in-shell seeds are processed, they are first dried. Afterwards, they may be roasted or dusted with salt or flour for the preservation of flavor.
Sunflower seeds sold by the bag are either eaten plain, salted (sometimes called 'plain') or with flavoring added by the manufacturer. Flavor examples include barbecue, pickle, hot sauce, bacon, ranch, and nacho cheese.
In-shell, sunflower seeds are particularly popular in Mediterranean, Eastern European, and Asian countries where they can be bought freshly roasted and are commonly consumed as street food, the hull being cracked open with the teeth and spat out, while in many countries, they can be bought freshly packed in various roasted flavors.
