Summary:
A Bulgarian research institute has developed an innovative technology and equipment for extraction of bio-active substances from wild or cultivated plants using solvent extraction techniques. It can be applied for extraction of various agents such as pharmaceuticals, nutriments, flavors, colorants, etc. The exhausted vegetable mass is environment friendly. The unit seeks industrial partners under commercial agreement with technical assistance.
Description:
The research institute has more than 40 years of experience in R-Y-D activities in the field of chemical technologies and chemical engineering. The unit has vast international experience in joint projects and science-business collaboration.

Herbs and spices are widely utilised in the food, health, pharmaceutical and other industries. Their beneficial effects to the human body have been attributed to the presence of active phytochemical ingredients with some efficiency for disease treatment and health enhancement. The substances in herbal products have broad application in different fields. Herbal processing and extraction technologies have been developed to obtain the optimal amounts of active ingredients from herbs and spices and to cope with the rising demands for herbal products but efficiency and flexibility still remain a problem.

The developed technological solution is based on solvent extraction techniques. Bio-active substances such as pharmaceuticals, nutraceuticals, flavours, colorants, etc. can be extracted from wild or cultivated botanicals (spices or herbs). After the extraction process is complete, the retained solvent is almost completely removed from the exhausted solid mass and reused in the process. The exhausted vegetable mass can be deposited with no harm for the environment or even directly used for feeding farm livestock. The process can also be easily adopted in water-steam distillation systems, suitable for production of natural aromas or essential oils. Both processes can be performed consecutively using the same equipment.

The extractors operate at atmospheric or reduced pressure. The latter mode is applied in case of thermo-sensitive products. Choosing the appropriate vacuum level, one can remove most of the solvent residue from the enriched extract, operating in the range from 30°C to 60°C.

Tailor-made extraction systems meeting the needs of both large and small production plants have been developed: installations applying cross-current percolation extraction scheme suitable for production plants of any size and installations applying "dip-and-drain" technology which is recommendable for small size companies with flexible production programs.

The research unit seek commercial agreements with technical assistance with companies offering expertise for adaptation to specific agents that are to be extracted and providing technical know-how.
Advantages and Innovations:
- the novel technology and equipment is with 20 % higher efficiency in comparison to similar technologies;
