  • How to extract volatile oils from onions?
  • Procedure of extracting onion volatile oilscoupling the pilot and small scale device based on multi-rectification. Because there is more than 90% water in fresh onions , it is not necessary to add water into the extraction tank of the pilot equipment during the extraction process.
  • How to extract onion essential oil?
  • Current research has been done to determine how to extract onion's essential oil. It contains organosulfur compounds, and those are the major elements. By using traditional techniques like maceration, steam distillation, Soxhlet extraction, etc., the earlier study has been verified.
  • How to enrich onion distillates from pilot rectification?
  • Multi-rectification on lab scale was used to enrich onion distillates from pilot rectification. Onion volatile oils from two kinds of onions of two growing areas were extracted and compared. GC–MS results indicate that sulfides are main flavors in the prepared onion volatile oils.
  • How is onion oil made?
  • One method of production of onion oil is steam distillation of crushed onion bulbs, which consist of a complex mixture mostly formed by mono-, di-, tri-, and tetra-sulfides with different alk yl groups (Hosoda et al., 2003). Alk (en)yl sulfides are perceived as odorants like sulfur, fried onion, garlic, and/or cooked cabbage (Blank, 2002). Thus,
  • Why is onion oil used in food industry?
  • In addition, its constituents can stabilize free radicals, act as an antibrowning agent, and inhibit the growth of pathogenic and spoilage microorganism. For this reason, onion oil is well appreciated by the food industry. Main volatile compounds identified in onion oil. Content may be subject to copyright. Content may be subject to copyright.
  • Does onion oil inhibit Lium rubrum?
  • lium rubrum was completely inhibited by 200 ppm of onion oil (Zohri et al., 1995). sulfoxides. The number of carbons in alk (en)yl group and sulfur atoms in molecules influenced antimicrobial activity of sulfides (Kim et al., 2004a). Sulfur compounds may be inv olved in the inhibition of the bacterial activity of key enzymes
