Hanyuan Zanthoxylum Bungeanum Maxim Flavor Compositions Study And Zanthoxylum Oil Processing Technology Improved Design

The study summarized the chemical composition of Zanthoxylum Bungeanum Maxim, introduced the distribution of resource and domestic and overseas study level to the plant. On this condition, studied the flavor composition of Hanyuan Zanthoxylum and optimized the processing technology of the traditional Zanthoxylum Oil. According to the study of Zanthoxylum flavor compositions, we selected the main flavor compositons, and used Limonene, Linalool and Acylamide as the key factor of the flavor compositions in Zanthoxylum Oil. It supplied the reference to making Zanthoxylum Oil standard. By the design of Zanthoxylum Oil processing technology, we found the key factor to influence the distilling rate of Zanthoxylum flavor compositions, improved the production efficiency and the utilization ratio of the Zanthoxylum resource, and improved the quality of Zanthoxylum Oil at the same time. The flavor compositions of Zanthoxylum Bungeanum Maxim were distilled by water vapor and organic solvent, separated and identified by GC/MS. The results showed that: the main scent compositions of Hanyuan Zanthoxylum were Beta-Myrcene, Limonene, Beta-Ocimene, Linalool, Linalyl acetate, Germacrene D etc. The anesthetic compositions were acylamide compounds. During the distilling the flavor compositions by organic solvent, we found that aether was the best organic solvent among ethanol, aether and acetone, as variety of the flavor compositions. According to the main compositions of Zanthoxylum of Hanyuan and many else regions, the study selected Limonene, Linalool and Acylamide as the key factor of the flavor compositions in Zanthoxylum and the oil. And what's more, we found the way to mensurate these compositions of Zanthoxylum and the Oil. The content of Limonene and Linalool can be mensurated by GC, and the content of Acylamide can be mensurated by ultraviolet spectrophotometer. The results showed that the key factors that influenced the quality of Zanthoxylum oil were concentration, temperature and time. The best condition of this factors were Zanthoxylum(w) : seed oil (v) = 1 : 2, 85℃and 10min. Under these conditions, the contents of limonene and linalool in the oil were 21.29mg/ml,6.3mg/ml respectively, the content of acylamide was 0.686% and the rate of extraction of essential oil and acylamide were 88.78% and 83.97% respectively. The study designed the volute countercurrent extracting equipment according to the capacity of enterprise and the results of extracting experiments. The main technological parameters of this equipment were that the thickness of helical blade was 6mm, the space was 100mm, the length was 20m, the heat preservation material was 30mm magnesium carbonate asbestos marl, the diameter of helical was 0.35m, the power of equipment was 0.124kw, the rated power of electric motor was 0.179kw and the rotational speed was 20r/min. Besides, the sensory organ data and absorbance of Zanthoxylum Bungeanum Maxim oil stored under room temperature were determined, the results showed that the flavor compositions in Zanthoxylum Bungeanum Maxim oil was stable, and the self-life was 8 mouth at least.
