The Essential Oils
Most of the aromatic crops contain aroma subtances in the plant cells and, its normally known as essential oil. These aroma materials can be derived from plants and animal parts that have been used since many decades by global flavour and fragrance (F&F) industries to produce flavours, essential oils, concretes, absolutes and perfume materials. Essential oils are the famous ancient materials especially for producing perfumery, medicines and aroma materials; and starting in year 1930, a new era of aroma chemical material is manufactured, synthesized and fractionated from aromatic substances. Nowadays, essential oils are very important in our life-styles and wellness; and most of the essential oils can be used as value added in the F&F blending as speciality aroma in foods, beverages, confectioneries, traditional medicines, nutraceuticals, cosmeceuticals and even pharmaceuticals.
Essential Oil Notes as an Arts of Perfumery Blending
Perfumery is an art of blending; it is a combination of aroma notes known as top, middle and base notes (Table 1).
Table 1. Natural aroma materials and note classifications
Essential Oils/ Aroma Materials |
Perfumery Notes |
Limes | Top notes |
Oranges | Top notes |
Citronella | Top notes |
Ylang-ylang | Middle notes |
Roses | Middle notes |
Jasmine | Middle notes |
Patchouli | Base notes |
Sandalwood | Base notes |
Vertiver | Base notes |
Agarwoods | Base notes |
Most of the citrus materials presenting a high aromatic essential oil that are classified as top notes. Meanwhile floral materials presenting a mild aroma volatile and classified as base notes. A long-lasting aroma material that can contribute for a long-lasting aroma with a characterising of deep, strong balsamic and woody are commonly contributed by woods and some leafy parts. They are usually produced by agarwoods, sandalwoods, cedarwoods, patchouli and vertivers and having a strong perfumery note as base notes. Patchouli is a base note and act as fixative material in the perfumery. Natural and aromatherapy perfumes can be formulated and designed by perfumers by combinations of these three notes (base, middle and top notes) with a master skill to present a harmony aromatic perfumes or aromatherapy blending.
Patchouli Essential Oil
In Malaysia the most unique and valuable aromatic crops are Patchouli, locally known as Nilam. Dried patchouli plants are traditionally used in the past by Malaysian and Indonesian to protect batik or clothes in the cabinets from insects besides giving aroma to the clothes. The Patchouli is an aromatic herb contains essential oil and having a very unique and natural aromatic derived from its essential oil substances. Patchouli essential oil (PEO) is one of the most popular perfumery materials and perform high demand in world-wide trades as fixative materials for fragrance and cosmetic formulations. PEO is very unique and its chemical components cannot be synthesized. PEO is suitable for a masculine perfumery ingredient and possesses a fixative material in the perfumery blending. Patchouli has been suggested by Malaysian Agricultural Research and Development Institute (MARDI) for farmers and entrepreneur programmes due to its essential oil is highly expensive and high demand in global for flavour and fragrance (F&F) industries.
Helping Farmers and Industries
Malaysia is currently focused in planting aromatic crops for helping farmers and industries for these new sectors of manufacturing of flavour and fragrance (F&F) products. However, the cost of productions is higher than Indonesian and Thailand essential oils. In this case, some affords are focused for business plans such as conducting courses and training several farmers, entrepreneurs and industries in producing essential oil base products such as aromatherapy, soap, bath gel, shampoo, cosmetics, perfumery and insect repellent products.
Essential Oil Plants
In Malaysia, essential oil distillers are locally built for specific industrial production needs and specialty ingredients. In Table 2, some of the distiller type and location of essential oil distillers are scattered in Malaysia. Besides distillers, there are many types of high-tech systems are set-up for processing aromatic extracts that can be found in MARDI, FRIM, universities and private companies such as fractionation systems (molecular distillations), agarwood conventional distillers, vanilla extractors, sub-critical gas extractors, and supercritical CO2 extractors found in Malaysia.

MARDI Industrial Scale Essential Oil Distiller
The local essential oils are produced using an industrial scale steam distiller system (Essential oil incubator) located at MARDI Station Kuala Linggi, Masjid Tanah Melaka, Malaysia. A Standard Operation Procedures (SOP) for essential oil productions of Patchouli (Nilam), Lemongrass (Serai makan), Citronellal (Serai wangi), Cinnamon (Kayu manis), Lemon myrtle, Kaffir Lime (Limau purut), Kasturi lime (Limau Kasturi) and other aromatic crops are successfully established by MARDI (See Table 3).
