The present review article is intended to provide comprehensive insights into the techniques of sunflower cultivation, methods of processing, and opportunities for value addition through a variety of applications. Sunflower (Helianthus annuus L.) is an economically valuable crop, admired for its vibrant yellow flowers and seeds rich in high-quality oil. The oil derived from sunflower seeds is nutritionally valued for its high content of unsaturated fatty acids, such as linolenic and linoleic acids, which help to reduce cholesterol levels and prevent arterial fat clots. Moreover, it contains essential vitamins A, D, E, and K. Sunflower cultivation primarily occurs in warm regions, aligning with the plant’s climatic preferences. As a short-lived plant, sunflowers demonstrate drought resilience due to their deep root system. In recent years, the use of sunflowers has significantly expanded, driving economic growth. The demand for products derived from sunflowers, including sprouts, roasted seeds, seed oil, and even sunflower-based agricultural tourism, has increased exponentially. Notably, sunflower seeds and their oil hold particular importance as they form the basis for integrated production systems, contributing to the creation of various food and non-food products. By presenting this information, we aim to provide a comprehensive guide for those interested in enhancing the utilization of sunflowers across various sectors.
