The outlook of garlic oil


China is an important garlic producer and exporter in the world, but there are relatively few deep-processing of garlic, mainly exporting primary products and raw materials. In order to enhance international competitiveness, garlic is further processed, especially high-quality garlic oil. It is very necessary to make products develop in the direction of high added value. This requires continuous improvement of the extraction process of garlic oil. The traditional steam distillation extraction method and organic solvent extraction method have long extraction time, and the extraction rate of garlic oil is relatively low. Supercritical CO2 extraction technology has the advantages of short production cycle, high extraction efficiency, safety and reliability, among which pilot and industrial applications are already in progress. It is believed that with the further deepening of the study of combining supercritical extraction technology with industrialization, the application of this technology in the further processing of garlic will develop rapidly. The new ultrasonic and microwave-assisted extraction technology, because it has the advantages of improving the mass transfer rate and shortening the extraction time, has gradually shown advantages in the extraction of natural products. However, such methods are still mainly in the laboratory research stage, and their large-scale application in industrial production needs further research. At the same time, in the extraction process of garlic oil, the deodorization technology and the stabilization technology of allicin should be continuously improved and perfected to ensure that the extracted garlic oil has good quality and good activity. At the same time, we should step up the research and development of garlic oil deep-processed products, and use good products to help raise people's awareness of garlic oil and promote the development of this field.
