Zanthoxylum is a common spice, which is widely used in daily life. The extraction of zanthoxylum is a complex process, and some important matters need to be paid attention to to ensure that the quality of the extracted oil is excellent. The following will introduce the matters needing attention in the extraction of pepper oil.

first, choose high-quality pepper raw materials. The first step in extracting oil from prickly ash is to choose high-quality prickly ash raw materials. High-quality pepper raw materials can ensure that the extracted oil is rich in flavor and bright in color. Therefore, it is important to choose fresh, intact prickly ash fruit as a raw material before extracting prickly ash oil.

second, pay attention to prevent oxidation during the extraction process. In the extraction process of the oil element of the flower, pay special attention to prevent oxidation. The effective components in the oil of Zanthoxylum are easily affected by oxidation, so necessary measures should be taken in the extraction process to reduce the effect of oxidation on the quality of the oil.

third, the use of appropriate extraction techniques. There are many kinds of techniques for extracting oil from Zanthoxylum, such as distillation and solvent extraction. When selecting the extraction technology, the most suitable method should be selected according to the actual situation to ensure that the purity of the extracted oil is high.

fourth, temperature control in the extraction process. The control of temperature is very important when extracting the oil of Zanthoxylum bungeanum. Too high or too low temperature will affect the oil extraction effect, so according to the specific circumstances of the reasonable control of the temperature in the extraction process.

fifth, pay attention to hygiene during the extraction process. In the process of extracting the oil element, we should pay attention to hygiene. The extraction equipment, containers, etc. should be kept clean, and necessary anti-corrosion measures should be taken to avoid impurities contaminating the oil.

sixth, storage after extraction. After extracting the oil element, pay attention to proper storage. Avoid direct sunlight, as well as with oxygen, moisture and other harmful substances, affecting the quality of the oil.

To sum up, there are many things that need to be paid attention to when extracting prickly ash oil, but only when every link is strictly controlled can high-quality prickly ash oil be extracted. It is hoped that this paper can be helpful to the process of extracting the oil of the flower.
