  • How to make sunflower oil?
  • When it comes to making sunflower oil, the two main methods are cold pressing and solvent extraction. Cold pressing is the more traditional method of extracting oil from the sunflower seeds, and involves pressing the seeds without any heat.‌
  • How is sunflower oil pressed?
  • Sunflower oil can be pressed using either cold-pressed or hot-pressed methods. Cold pressing sunflower oil involves oil extraction through physical mechanical means without heating, or at low temperatures (<40°C). This entire process occurs at a low temperature, resulting in a lower oil yield but preserving the authentic taste of the seeds.‌
  • What is cold pressed sunflower oil?
  • The most common method of producing sunflower oil is known as cold pressing. This process involves pressing the sunflower seeds without the use of heat, thereby preserving the oils natural nutrients and antioxidants. Cold-pressed sunflower oil is considered to be the highest quality, as it retains all of its beneficial properties.‌
  • What is hot pressing sunflower oil?
  • Hot pressing sunflower oil involves pre-processing sunflower seeds through steps such as roasting or cooking at high-temperature (60°C to 120°C), enhancing the oil's fragrance and oxidative stability. This effectively breaks down sunflower seed structure for pressing.‌
  • How much sunlight does a sunflower need?
  • Sunflowers produce best in locations with direct sunlight (6 to 8 hours per day); they want long, hot summers to flower well. Sunflower seed oil is obtained from the seeds within the brown hub in the center of the sunflower plant. Sunflower oil is light in taste and gives more Vitamin E than any other vegetable oil.‌
  • What is the difference between hot pressing and cold pressing sunflower oil?
  • Hot pressing results in a more ideal oil yield, extracting a larger portion of the oil content, but high temperatures can lead to nutrient loss. Cold pressing, on the other hand, preserves the nutritional components of the oil, making cold pressing popular in small and medium-sized sunflower oil mills.
