Onion Oil is a natural vegetable oil extracted from onion bulbs (Allium cepa L.), which is generally extracted by steam distillation or supercritical CO₂ extraction technology to ensure the stability and purity of the oil while retaining the active ingredients. Its main volatile components, such as dipropyl disulfide and dipropyl trisulfide, not only give it the typical "onion aroma" and "garlic aroma", but also bring potential physiological activities such as antibacterial and conditioning.
This onion essential oil has cross-industry application potential due to its natural source, concentration process and chemical composition diversity, making it an important natural raw material for the development of many new products.
