The rose is extensively cultivated in bulgaria, france and turkey in india. and in india rose cultivation is done on about 10,000-12,000 hectares of lands. We offer pure quality rose oil, which is extracted with the process of distillation. the important areas of rose cultivation are :

    distillation of rose oil distillation as soon as the harvesting is over flower are taken to distillation plant for processing. In case, there is delay in processing, flower should be spread at low temperature and water should be sprinkled to avoid the loss of oil through evaporation or flower should be dipped in water tank and same water will be used in distillation. In india, three different methods are in practiced for the processing of rose oil. 1:-deg and bhapka method (hydro-distillation) majority of rose distillers in india use traditional distillation equipment which consist of round kettle (deg) and a receiver (bhapka) hich also serves the purpose of condenser. These are made of copper. The kattle and receiver are connected with bamboo (chonga) through which steam from kettle reaches to the reciecer. The receiver is placed in a smell water tank, which helps in the condensation of vapours containing rose oil. The ketlle has a capacity of 50-100 kg flower per batch and takes about 6-8 hours to the complete the distillation. After distillation is over the receiver is removed and oil is separated. This methods gives a recovery of 0.01-0.015% which is significantly lower than the other method described later. 2:-direct fired distillation unit (hydro-steam distillation) the unit consist of a kettle (still),a column, condensor and receiver.the whole unit can be of copper or stainless steel. The capacity of still may rang from 100-200 kg flower per batch. To increase the fuel efficiency and to generate sufficient steam, fume tubes are fitted in the bottem of the still. The outlet of the receiver is connected with the column to recycle the condensate into the still, after the separation of oil takes place in the receiver. This process is known as “cohobation” which has been found to improve the recovery of oil. The plant is simple in operation and can be operated by a semi skilled woeker. Direct fierd plant takes cost rs. 2.5 – 3.0 lacs, if made out of stainless steel. The plant takes about 4-6 hrs per batch for completion of distillation. 3:-boiller operated unit (steam distillation) this the most modern method of distillation and suitable for large scale production of oil. The whole plant consist of three units, a distillation unit and a cohobation unit.flower are charged in the distillation unit and distilled after passing through a receiver fed to another still through cohobation column to ensure complete recovery if oil. The part of the oil is also collected from first receiver and the remaining from the second. It is advantageous to collect the distillate from the second separator and feed back it to the distillation tank in place of fresh water. Complete distillation in boiler operated distillation unit take 4-5 hrs. The oil recovery veries from 0.025% - 0.03%. Depending upon the capacity of the boiler, the unit may cost rs 7-9 lacs. The other advantegge with the system is the several distillation unit can be connected with the boiler. physical-chemical properties true rose oil is a light yellow, occasionally slight greenhs and semi soli at room temperature. The odour of the rose oil is very pleasant, powerful and characteristic of fresh rose and the flavour is sweet and somewhat honey- like. The pysical properties of the oil :
    • appearance : light yellow, occasionally slight greenish, transparent.
    • sp. Gravity : 0.849 – 0.870 (at 30oc)
    • refractive index : 1.452 –1.466.(at 25oc)
    • congealing point : +18oc - +23.5oc
    • capital rotatoin : :- 1- -4
    major chemical constituents of rose oil are citronellol (22-32%) geraniol (12-15%),nerol (8-12%),linalool (1.5-2.7%),methyl eugenol (2.0-2.5%),eugenol (0.5%-1.0%) and rose oxide (1-1.3%). thee are several minor constituents which are present in traces in the oil. depending upon the strain, geographical region of cultivation and management practices, considerable variation may occur in the composition of oil. uses rose oil is one of oldest and most valuable perfumery material available in the world. No high grade perfume can be thought of unless it contains small quantity of rose oil. It imparts characteristic flowery note to the perfumery and depth to blended material. It is necessarily a constituent of a high grade perfume, cosmetics and flavouring material of food, soft drink and beverages. apart from perfumery, rose oil is also used in various preparation like ayurved, unani and other pharmacoias.
