ESSENTIAL OIL PRODUCTION UNDER PUBLIC SECTOR, PRIVATE PARTNERSHIPMODEL - V.S. VENKATESHA GOWDA FORMER GENERAL MANAGER KARNATAKA SOAPS & DETERGENTS LTD., BANGALORE-55 1 INTRODUCTION: Definition of Essential Oil : The scented oil obtained from natural sources is called Essential oil. An essential oil may be defined as a volatile perfumery material derived from a single source of vegetable or animal origin, which has been separated from that source by a physical process. Natural Essential Oils Are The JEWELS OF NATURE – only Kings & Queens and rich persons were supposed to use these essential oils and barter with other valuables. 2 PRODUCTION OF ESSENTIAL OILS: India is already world leader as far as production and export of essential oils and their value added products are concerned. Many factors go in favour of our country, 1) Biodiversity 2) Scientific manpower 3) Processing industry 4) Huge investment in trade Unless, all these four parameters are well addressed by any country, an industry cannot grow and achieve distinction. 3 The production of essential oils can be grouped in to five categories, 1) Essential oils for processing 2) Essential oils for fragrances 3) Essential oils for flavours 4) Essential oils for aromatherapy and natural medicines 5) Essential oils for pharma oils. 4 WORLD PRODUCTION OF ESSENTIAL OILS FOR PROCESSING (2011) Essential Oil Quantity (in MTonnes) Producing Countries Basil 500 India Cederwood 3000 China, USA, India Citrodora 1000 China, Brazil, India, S.Africa Citronella 1500 China, Indonesia, India Clove Leaf 4000 Madagascar, Indonesia, Zanzibar Eucalyptus 5000 China, India, Australia Lemongrass 400 India, China, Guatemala Litsea cubeba 1500 China M.

Hydro distillation : in order to isolate essential oils by hydro distillation, the aromatic plant material is packed in a still and sufficient quantity of water is added and brought to a boil, alternatively, live steam is injected in to the plant charge. due to the influence of hot water and steam, the essential oil is separated from the oil glands in the plant tissue. 6 Dry distillation : It is the heating of solid materials to produce gaseous products (which may condense into liquids or solids). The product are condensed and collected. This method usually requires higher temperatures than classical distillation. The method has been used to obtain liquid fuels from coal and wood. Supercritical fluid extraction : It is the process of separating one component (the extractant) from another (the matrix) using supercritical fluids as the extracting solvent. Carbon dioxide is the most commonly used supercritical fluid. (A supercritical fluid is any substance at a temperature and pressure 7 above its critical point, where distinct liquid and gas phases do not exist). Perfume: The word ‘Perfume’ used today derives from the Latin per fumum, meaning "through smoke”. Perfume is used to signify a pleasant scent or smell or a substance which emits a pleasing odour. Fragrance: ‘Fragrance’ means sweetness of smell. Like Perfume it comes from the Latin and is akin to the Sanskrit root, ghra. It’s used as a synonym for perfume, in the concrete sense of a substance which emits a pleasant odour. 8 NEED FOR DIVERSIFICATION Change in global scenario in export/import of agricultural commodities Falling prices of agricultural commodities Decreasing profitability of agricultural crops Danger of loss of jobs Ecological damage Change in consumer perceptions 9 AROMATIC PLANTS – NEED FOR DIVERSIFICATION More profitable than many field crops Plants for intercropping – complementary not supplementary systems Scope for value addition Ecologically sustainable 10 IMPORTANT ESSENTIAL OIL PLANTS GROWN IN INDIA AND THEIR USES PRINCIPAL CHEMICAL PLANT BOTANICAL NAME CONSTITUENTS INDUSTRIAL USES JAVA CITRONELLA CYMBOPOGON WINTERIANUS CITRONELLAL, PERFUMERY, RAW JOWITT.

Purity By GLC for reference purpose. 23 PROSPECTS OF CULTIVATION OF MEDICINAL AND AROMATIC PLANTS The number species of living organisms on earth is estimated to be about 13.6Milion, which includes about 2,50,000 species of plants. Out of these, 35- 70,000 species of higher plants may have been used for medicinal purposes at one time or another in different traditional medical practices. About 5000 species of higher plants have been exhaustively studied by the pharmaceutical industries as a source of new drugs. More than 120 drugs of known chemical structure, which are extracted from 95 24 species of higher plants are globally in allopathic medicine. It is estimated that there are about 47000 species plants in India, out of which 17000 are Angiosperms, representing 6% of world’s known flowering plants. Nearly 8000 plants have recognized for medicinal use in value traditional systems of medicine in India. There are about 1300 plants in India which are known to be medicinal aromatic plant. Out of which 65 plant species have demand in the world market. India share the 3rd largest producer natural essential oils next to USA and Brazil.
