Abstract:

Taking Scutellaria baicalensis as the research object, microwave-assisted eutectic solvent was used to extract the effective antibacterial component baicalin. The effects of 9 different properties of DESs on the extraction rate of baicalin were investigated, and DES-1 was determined as the optimal extraction solvent. On the basis of single factor experiment, using response surface method analysis, the highest yield of baicalin was 66.99 mg/g at extraction time of 16 min, liquid-solid ratio of 20:1(mL:g), and extraction temperature of 85℃. The compound preservation solution was prepared with baicalin, and its fresh-keeping effect was evaluated by measuring the physical and chemical indicators of fresh meat. The results show that the compound preservation solution containing baicalin can effectively reduce the decreasing rate of pH and the increasing rate of peroxide value and volatile base nitrogen. It can effectively inhibit the fat oxidation and protein decomposition of fresh meat, and as the concentration of baicalin increases, the preservation effect of fresh meat is getting better. The study can be used as a technical reference for baicalin in meat storage and preservation.

Key words: microwave extract, antibacterial, baicalin, eutectic solvent, compound preservation solution, the preservation of fresh meat
