Technology of production of biocomposites with antioxidant and antitumour activities

Description

Biocomposites with new original formula:
1) green tea extract + red wine lees;
2) green tea extract + red wine lees + extract of citrus peel.

The biocomposites are rich in polyphenolics (15-22%), as well as in other biologically active compounds such as pectin, amino acids, organic acids etc. They do not consist of any synthetic chemicals and additives, aromas and enhancers - that is are absolutely natural products. The biocomposites are produced in a dry powder ready to use form, easily soluble in hot/cold water, have pleasant natural reddish and/or brownish color, aroma and characteristic astringent taste. Technological instructions for production of the composites have been elaborated and corresponding technological parameters and production cost were determined and optimized.

Due to presence of full polyphenolics “cocktail” and bioactive compounds, the biocomposites show high antiradiation, antioxidant, antimicrobial and antitumour activities as well as have high nutritional value.

Innovative Aspect and Main Advantages

The proposed technology is supposed to use only physical methods such as extraction, filtration, and concentration and spray drying rather than chemical ones. As an advantage of the technology an extraction of plant material with wine lees instead of water should be mentioned. As a result the obtained extract is almost two times more concentrated and rich in bioactive compounds comparing with the water extract. This in turn causes up to 30% saving of energy and makes technology feasible and economic. Plant raw materials are commercially available and a primary cost is competitive with existing analogues. An average primary cost of the products is about 15-16 USD per kg.

Areas of Application

The biocomposite can be used in food industry as biologically active additives/colorants to increase nutritional and biological value of the products as well as to crate new features of the product and raise its quality. Possible areas of application are as follows:

  • confectionary industry;
  • diary products;
  • soft and tonic drinks;
  • natural juices
  • as antiradiation, antioxidant, antimicrobial and anticarcinogenic preparations in pharmaceutical industry and cosmetology.

Respectively, potentially interested companies are food producers and pharmaceutical companies that are focused on natural products rather than on synthetics.
