zanthoxylum oil, scallion oil, a sour agent, black 
pepper oil, a 
rosemary extract with the 
mass concentration of 0.04 to 0.07 percent, 2-pentanol with the 
mass concentration of 0.05 to 0.15 percent, 
hexanal with the 
mass concentration of 0.5 to 0.15 percent, 2-nonanone with the mass concentration of 0.5 to 1.5 percent, 2, 5-dimethyl 
furan with the mass concentration of 0.5 to 1.5 percent, 
calcium chloride with the mass concentration of 0.15 to 0.25 percent, arteannuin with the mass concentration of 0.5 to 1.5 percent, 
anethole with the mass concentration of 0.5 to 1.5 percent, 
eugenol with the mass concentration of 0.5 to 1.5 percent, 
myrcene with the mass concentration of 0.5 to 1.5 percent and d-
limonene with the mass concentration of 8 to 12 percent. By adopting the pickled
