(1) The SWEX instrument uses subcritical water extraction at different temperatures to extract a range of organic species from samples for analysis by multiple instruments.
(2) It aims to provide an integrated sample handling and extraction system to lower costs and improve reliability for future Mars missions searching for organics and life.
(3) Testing will extract and characterize organic molecules from various samples like soils and ice over a range of subcritical water temperatures to determine what is extracted and supply identical extracts to downstream detectors.
This topic gives the basic idea of the essential oil, its characteristics, methods available for extraction and where exactly essential oils used in food.
this is chemistry related to food. rancidity - a phenomena of oxidation of oils and fats which leads to their foul smell and taste. it can be prevented in homes by keeping foods containing oils and fats, in air tight containers. packets of chip are filled with nitrogenous gas to prevent rancidity. go on reading this ppt that I had prepared as my holiday homework for chemistry, it is very informative even if you just want to know about the phenomena. - mansvini
Essential oils are volatile (quickly evaporating) aromatic fluids extracted from plants through steam distillation, or in the case of citrus fruits through expression (or cold pressing) of the rind to obtain an oil that retains a juicy, fresh fruit scent.
Various extraction methods are used in the manufacture and extraction of essential oils, and the method used is normally dependant on what type of botanical material is being used.

Fatty alcohol. Define fatty alcohols Describe the production processes of fatty alcohols and its derivatives Draw the flow chart of fatty alcohol production Explain the uses and application of fatty alcohols.
3. Definitionof Fatty Alcohols Fatty alcohols are the workhorse raw materials that facilitate the existence of products such as shampoos, shaving creams, laundry detergents, etc, and are produced at a rate of about one-and-a-half million tonnes per year and growing. Fatty alcohols are oleochemicals derived from vegetable feedstocks. The feedstock raw materials include coconut and palm kernel oils. These refined vegetable oils are first converted to a methyl ester or fatty acid. This reaction generates crude glycerine. The intermediate methyl ester or fatty acid are then fractionated and hydrogenated to produce fatty alcohol. Sources : http://www.pgchemicals.com/products/fatty-alcohols/

8. Hydrogenation All natural fatty alcohol processes are based on renewable fats and oils like coconut, palm oil,palm kernel,rope seed and soya bean oil. It has been proven that hydrogenation of methyl esters are preferred alternatives than hydrogenating the oils directly. Using fixed bed hydrogenation process offers the advantage of lower hydrogenation temperatures and pressures. Using special catalysts, this process is able to produce unsaturated fatty alcohols too. To produce fatty alcohols, there are three routes which is acid route,ester route and wax ester route that are shown in the following block diagrams.

Advancement in neem oil extraction process Prem Baboo
This paper describes a process of preparation of neem oil water emulsion & coating of urea in fertilizer plants, at site of urea production. The neem tree found in Asia and basically Indian sub continent. The basic part for neem oil used is seed of the neem known as kernels .Different method are available to obtain neem oil including one new method Supercritical method for extraction of neem oil from kernels.Now a days the main demand of neem oil in fertilizers Industries for coating of Urea and other fertilizers. “Government of India has done away with the cap on neem- coated urea and now it can be produced 100%. It is a win-win situation for both industry and farmers. It has been noted that farmer’s income would increase with the help of neem-coated urea as productivity would increase with less usage of urea.”Consequently the demand of Neem oil drastically increasing. In this paper some description of oil preparation method. Using carbon dioxide: methanol for supercritical fluid extraction is the maximum yield eco friendly process but slightly economical.
Extraction and Production of Essential Oils
(Phytochemicals, Aromatic Chemicals, Aromatic Compounds, Spice Oils and Oleoresins, Curcumin, Rose Oil Extraction, Chilli Oil, Ginger Oil, Black Pepper Oil, Chilli Oleoresin, Cresols, Menthol Oil, Clove Oil & Citronella Oil, Patchouli Oil, Garlic Oil)
The essential oils are extracted from the botanical material using a variety of extraction methods to suit the material extracted from and are highly odoriferous liquids.
Essential oils are the fragrant, highly concentrated natural constituents that are found in plants. They are what give the plant its characteristic odour and contain the healing power of the plant from which it was extracted.

(1) Principle Investigator NASA Ames , (2) NASA Ames/KISS Institute of practical robotics
(3) NASA Ames/SETI Institute, (4) NASA Ames/Lockheed Martin
Objective:
We develop a prototype organics extractor to supply a suite of instruments using subcritical water as a
solvent that:
- Receives scooped or drilled surface samples from a range of materials ie soils, ice etc
- extracts a range of potential organic molecules using subcritical water
- delivers an identical characterized extract product to downstream detectors
Left: Icebreaker drilling for life on Mars
Advantage for NASA Ames:
(1) Good Science: Provides an identical characterized extraction from the sample to a suite of
organics and biogenic organic detectors.
(2) An Integrated sample handling & extraction system: Provide an integrated sample handling
package of drill, a robot sample transfer arm and an organic extraction instrument.
(3) Lower Costs and greater reliability: Designing and testing 1 generic extraction processor saves
cost and focuses on reliability.
3. Method: The Science of Subcritical Water Extraction
Why an extraction process?
Separate and concentrate the target species prior to delivery to analyzers. Lowers complexity of
analyzers which otherwise have to incorporate this function
Why Subcritical water?
We can separate organic species as a function of subcritical water temperature and pressure
Other methods require many organic solvents for the same extraction.
We aim to affirm: What organics are extracted over the subcritical temperature range.

- Any mission that has organic detection as an objective
- By solving the sample handling problem in a system, we relieve many other candidate
instruments of also having to develop their own independent sample handling
hardware.
- The Icebreaker life search mission, a mission concept for Discovery does organic
analysis and biomarker detection on extracted product. This concept would simplify
sample handling for the Icebreaker instruments
