Abstract
The invention discloses a carbon dioxide extraction method of garlic essential oil. The method comprises the following steps that garlic heads and garlic stems of garlics are respectively crushed andbeaten into a paste shape; then, mixing is performed to form mixed garlic paste; the characteristic that the self specific garlic ammonia enzyme of the garlics can oxidize the garlic paste into allicin under the aerobic condition is utilized, so that the mixed garlic paste is subjected to fermentation treatment so as to improve the content of effective ingredients in the garlic essential oil; then, an extracting agent is used for extracting and filtering the fermented garlic paste; filter liquid is subjected to carbon dioxide extraction and grading pressure reduction separation; the finished product of the garlic essential oil is finally obtained. In addition, the principle that ice points are different is utilized, so that the water and the extracting agent in residual juice of the mixedgarlic paste extracting liquid after the extraction are sequentially removed, so that the garlic essential oil is obtained again. When the carbon dioxide extraction method of the garlic essential oilprovided by the invention is used for extracting the garlic essential oil, the extraction rate of the garlic essential oil is effectively improved; meanwhile, the effective ingredients of the target product are reserved to the greatest degree; the industrial production is facilitated.
