Research on Optimization of Extracting Spicy Hot Pot Oil Process by Supercritical CO2 Extraction Technology
Most of the extraction methods of traditional hot pot spicy hot pot oil are ordinary infusion extraction methods,which have the characteristics of long production cycle and low extraction efficiency.As a relatively new extraction technology in the field,supercritical CO2 extraction technology has the advantages of high extraction efficiency,safety and non-toxicity,and the extractant can be reused.In this study,the contents of capsaicin and Zanthoxylum amide were used as indexes to optimize the extraction process of spicy hot pot oil by supercritical CO2 extraction technology,and the optimal extraction conditions were obtained:the extraction time was 40 min,the CO2 flow rate was 30 kg/h,the extraction temperature was 60℃,and the extraction pressure was 2.5 MPa.After extraction,the content of capsaicin was(105.28±2.06)mg/g,and the content of Zanthoxylum amide was(87.65±1.04)mg/g.Compared with the traditional extraction technology,extraction rate and sensory scores of spicy hot pot oil were higher.After testing,the physical and chemical indexes of the extracted spicy hot pot oil met the requirements of relevant national and enterprise standards,and this study can provide technical basis for future industrial processing.
