• What are the kinetics and mechanism of sunflower seed oil extraction?
  • The kinetics and mechanism of the extraction process investigated. It is shown that the process of extracting sunflower seed oil is complicated and include as intra-diffusion and outer-diffusion oil transfer is similar to extraction of target components from other seeds of plant material (amaranth, rapeseed, etc.).
  • 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.
  • How many sunflower seeds are edible and oil sunflower seeds?
  • This study aimed to comprehensively compare and analyze the raw material characteristics, basic physicochemical properties, and processing characteristics of eight sunflower seeds (four edible and four oil sunflower seeds) and the correlation between these parameters.
  • How is sunflower seed processed for oil production?
  • Figure 1 shows a flowchart of sunflower seed processing for oil production that results in sunflower seed byproducts (whole and defatted sunflower meals) (Figure 2). The process starts with the crushing of the seed, where the whole sunflower meal is generated.
  • Do edible sunflower seed cells contain oil?
  • The cell size, shape, and distribution of oil and protein varied significantly among different sunflower seed varieties. SEM revealed that the cells of edible sunflower seed cells are large, with minimal oil spillage in the cross-section.
  • How to extract oil from sunflower seeds?
  • Petroleum ether (boiling point range 30¨C60 ¡ãC) was used to extract oil from different varieties of sunflower seeds at low temperatures; sunflower oil was obtained by rotary steaming, and the remaining sunflower seed meal was dried naturally in the fume hood for use.
