Abstract

The invention discloses a method for extracting anise camphor through rectification, and the method comprising the following steps: adding salt to anise tree tender leaves and evenly mixing, then drying and frying, soaking and filtering to obtain a mixture, then adding dry soybeans into the mixture, then filtering, heating and filtering to obtain a mixed oil, then distilling the mixed oil and standing for stratification to obtain an extract, then placing the extract in an extractive rectification tower for processing to obtain an extract, and dehydrating the extract to obtain anise camphor. The invention has a simple operation method, and no organic reagent is used in the extraction method, thus reducing the probability of an organic reagent mixing with anise camphor. Instead of a recrystallization process, the invention adopts an extraction process through rectification, improving the yield of anise camphor.

Description

technical field [0001] The invention relates to the field of agricultural product processing. More specifically, the present invention relates to a method for rectifying and extracting anethole. Background technique [0002] Star anise is a unique aromatic plant in my country. It mainly grows in Guangxi, Guangdong, Yunnan, Fujian, Sichuan and other places. Guangxi has the most output and the best quality. The main production areas of Guangxi are concentrated in the south and west of Guangxi, including Chongzuo, Fangchenggang, Qinzhou, Baise, Nanning, Yulin, Wuzhou and other cities are especially famous for the quality of Shiwandashan and Debao Lingyun. The annual output of star anise in my country is about 100,000 tons, accounting for 80-90% of the world's total output, while Guangxi accounts for about 85% of the national total output. Guangxi has become a veritable hometown of star anise. In addition to meeting domestic demand, star anise is also exported to the United Sta...
