Natural extracts from nature

Plant extract as a green, pollution-free, residual-free feed additive, because it has a certain antioxidant, immune regulation and growth promotion, many industries are currently useful to plant extract, such as food, medicine and health care, cosmetics and so on. Here is to share the extraction process of the main active ingredients in plant extracts for you.

1. Water steam distillation method

This method is easy to obtain equipment, and the obtained components are easy to separate from water, but in the process of extracting active ingredients, the heat unstable components such as polysaccharides are easy to be destroyed, and the volatile oil is easy to hydrate with water and lead to taste deterioration.

2. Ultrasonic-assisted method

This method has low extraction temperature and low energy consumption, which is suitable for the extraction of polar and thermal unstable components, but the existing ultrasonic instrument capacity can not realize industrial production.

3. Supercritical CO2 extraction method

This method can effectively prevent the oxidation and escape of heat-sensitive substances, in addition, because there is no solvent residue, so the extracted raw material can be used as feed or continue to extract other ingredients, but this method will be due to high pressure, physical property data is missing, and high investment costs, but also high safety requirements.

4. Enzymatic hydrolysis

This method has the mildest extraction conditions, is a low-temperature extraction method, the reaction speed is very fast, impurities are easy to be removed, but this method has high cost, high equipment and technical requirements, and has great limitations. The main use of cellulase pectinase protease, etc. (mainly cellulase), damage the cell wall of the plant, in order to promote the maximum dissolution of the plant active components of the separation of a method. In the extraction process of enzyme extraction, the selection of enzyme, enzyme concentration, pH value, enzymatic hydrolysis temperature, enzymatic hydrolysis time will affect the extraction rate of plant extracts.
