oleoresin extraction plant

Oleoresin extraction (oleoresin extraction) is the extraction of liquid or semi-solid, resinous substances from plant materials such as spices, which contain the essence of the spice and are typically 5-20 times stronger than the original spice. Oleoresins are mainly composed of a small amount of volatile essential oils and a large proportion of non-volatile compounds (such as fixed oils, pigments, resins and pungent ingredients), which collectively contribute to the aroma, flavour properties and bioactivity of the spice.

Pepper is one of China's traditional 'eight flavours', rich in resources, but the processing by-products of pepper seed utilisation rate is low. Pepper skin is rich in volatile oils, alkaloids, etc., while the seeds contain oils and proteins. Pepper processing includes fresh and dried peppercorns, and subcritical low-temperature extraction can be used to extract the peppercorn oil resin, while peppercorn seeds can also be processed to produce oil and protein. Improving the utilisation rate of pepper seeds can help the sustainable development of the pepper industry.
The main components of oleoresin include the following:

1. Essential oils: Oleoresins contain essential oil components, these are the more volatile aromatic substances in plants.

2. Pungent components： Some oleoresins contain pungent components, which give the oleoresin a specific taste and flavour.

3. Colouring: Oleoresins also contain colouring components which affect the colour and visual properties of the oleoresin.

4. Resins: Oleoresins contain non-volatile resin components that play an important role in the consistency and flavour of the oleoresin.

5. Non-volatile oils: Oleoresins contain a number of non-volatile oils and fats which add to the richness and mouthfeel of the oleoresin.

6. Polysaccharides: Oleoresin also contains some polysaccharides, which have an effect on the consistency and functionality of oleoresin.

Subcritical extraction equipment is a kind of technical equipment used to extract vegetable fats and oils. Compared with traditional extraction methods, subcritical extraction has the following advantages:

• Low temperature: subcritical extraction is carried out at a lower temperature, usually between 40-80 degrees Celsius, which is lower compared to traditional thermal extraction methods, helping to retain the active ingredients in the oils and fats and reducing the loss of heat-sensitive substances.
• Low pressure: The pressure of subcritical extraction is usually between 10-20 MPa, which is lower compared to the high-pressure conditions of supercritical extraction, reducing the cost and energy consumption of the equipment.
• High extraction efficiency: subcritical extraction can improve the extraction efficiency of oil and grease, because in the subcritical state, the density and viscosity of the solvent is lower, which is conducive to the contact and diffusion of the solvent and grease, and improves the solubility of the oil and grease and the extraction rate.
• Good solvent selectivity: subcritical extraction can choose different solvents for extraction, according to the characteristics and requirements of the oil and grease, choose the right solvent, you can achieve selective extraction of specific components, improve the purity and quality of the product.

The extraction process is environmentally friendly: the solvents used in the subcritical extraction process are usually non-toxic, harmless, harmless to the environment and human health, in line with environmental requirements.
