  • What is sunflower seed processing?
  • Sunflower seed processing focuses on sunflower oil as the most valuable product. It is used as high-value oil in various food applications. The deoiled meal is considered a byproduct and is mostly used as animal feed. In 2011, annual world production of deoiled sunflower meal was at 16 million tons (FAO, 2013).
  • How is sunflower crushed for oil recovery?
  • Sunflower is crushed for oil recovery via one of two process methods, hard pressing or prepress solvent extraction. Hard pressing relies upon exerting high pressure on the prepared seed to separate oil from the solids fraction, historically recovering about 25% oil from the seed.
  • What is the export/production ratio of sunflower?
  • If we compare the export/production ratio of the main products involved in the vegetable oils and proteins markets, we see that sunflower is traded mainly after processing: 55% of the oil volumes were exported in 2018/19, 38% of the meals, and only 5% of the harvested seeds.
  • Why is refined sunflower oil popular in India?
  • Refined sunflower oil has found wide acceptance because of its high polyunsaturated fatty acid content, bland flavour, good storage stability and low viscosity (Semwal et al. 1996). Refined sunflower oil has emerged as one of the most popular cooking oil in India.
  • Why is prepress solvent extraction better than sunflower meal?
  • Because sunflower oil has a substantially higher economic value than sunflower meal, process economics improve significantly as the oil recovery yield increases. Therefore, prepress solvent extraction, with the highest oil recovery yield, is the process method utilized today for the majority of the sunflower seed that is crushed globally.
  • Can you buy crude sunflower oil from a foreign country?
  • New techniques like countercurrent bleaching and electrofiltration (ÖHMI) are under development (11). Purchasing crude sunflower oil (or seed) from certain countries involves the risk of PAH¡¯s (polyaromatic hydrocarbons) contamination, originated from direct fuel gas drying of the seeds or from environmental pollution.
