Scientists from the University of Food Technologies – Plovdiv, Bulgaria investigated an approach for valorization of waste materials of essential oil industry (focusing on the well-developed rose-oil industry in Bulgaria) for production of biologically active substances (polysaccharides, polyphenols, etc.). Further these substances can be potentially used in the field of cosmetics, food industry, etc. as well as approaches for their direct utilization are presented.

The rose oil, rose water, concrete and absolute obtained from roses are among the most appreciated products from the perfumery, cosmetic industry, medicine and for aromatherapy.

Rosa damascena Mill waste (solid residues or waste water) are rich in polyphenolic compounds. The isolated polyphenol rich extracts could be applied as antioxidant supplements (for meat products, in yogurts, beverages, etc.) and as stabilizer of natural color substances (for ex. stabilizing strawberries color due to complexation with anthocyanins).

Results have been presented by Dr. Anton Slavov at the First Workshop of ENABLING project, organized by BGBIOM in Sofia.

This work was supported by the Bulgarian Ministry of Education and Science under the National Research Programme "Healthy Foods for a Strong Bio-Economy and Quality of Life" approved by DCM # 577 / 17.08.2018".
