Oil extraction from

Green coloration, present in many vegetable oils, poses a particular problem in oil extracted from immature or damaged soybeans. Chlorophyll is the compound responsible for this defect. StmcturaHy, chlorophyll is composed of a porphyrin ring system, in which magnesium is the central metal atom, and a phytol side chain which imparts a hydrophobic character to the stmcture. Conventional bleaching clays are not as effective for removal of chlorophylls as for red pigments, and specialized acid-activated adsorbents or carbon are required. 

Another process employed to increase the formation of volatile compounds in fmit is that of bioregulators. When a bioregulator is appHed to lemon trees an increase in both the aldehyde and alcohol fractions of the lemon oil extracted from the fmit of the treated lemon trees was observed (78). 

The major component of the oil extracted from bell peppers has been shown, initially on the basis of mass spectral studies but subsequently by total synthesis, to be 2-methoxy-3-...

Sulfurol, n. sulfocarbon oil (olive oil extracted from marc, esp. with CS2). 

Nag and Haidar reported the purification of vegetable oil extracted from the seeds of Pongamia glabra and its ability to substitute commercially available factices [33]. Factices are usually used for mastication of NR during production of tubing, automobile parts, and window seals. The authors reported improvement in thermal stability of the NR vulcanizate after the factice was added. 

Recently, 19 diarylheptanoids, of which 6 are new, were separated and identified in turmeric by LC-ESI-MS/MS coupled to a DAD detector. More than 20 compounds were identified in the volatile oil extracted from turmeric by different meth-...

If sample patterns in a large database are each defined by just two values, a two-dimensional plot may reveal clustering that can be detected by the eye (Figure 3.1). However, in science our data often have many more than two dimensions. An analytical database might contain information on the chemical composition of samples of crude oil extracted from different oilfields. Oils are complex mixtures containing hundreds of chemicals at detectable levels thus, tire composition of an oil could not be represented by a point in a space of two dimensions. Instead, a space of several hundred dimensions would be needed. To determine how closely oils in the database resembled one another, we could plot the composition of every oil in this high-dimensional space, and then measure the distance between the points that represent two oils the distance would be a measure of the difference in composition. Similar oils would be "close together" in space,... 

Peppermint oil is the volatile oil extracted from the fresh leaves of the flowering plant of Mentha piperita via steam distillation. Peppermint oil contains not less than 44% menthol. American peppermint oil contains from 50 to 78% of free /-menthol (Fig. 13.12.1) and from 5 to 20% combined in various es-... 

Natural peppermint contains several components that, if ingested, lead to a cold sensation in the mouth. The best known and best understood is (-)-menthol (IV), which is the dominant component of the peppermint oil extracted from Mentha piperita and M. arvensia. 

FIGURE 1.14 Thin layer chromatogram of oil extracted from 26 fish samples observed under visible light. Only oilfish (lanes 1-7,11) and escolar samples (lanes 8-10) showed a characteristic spot at Rf = 0.6 (Ling et al, 2008a,b data from authors).

Turpentine oils extracted from pine resins are now marginal sources of terpenes pinenes, carene and some other monoterpenes are essentially obtained from the paper oils produced in the KRAFT process. Nevertheless this process is based on a treatment of wood chips in sodium sulfide, which leaves significant fractions of sulfur compounds in the paper oils. For the use of terpenes, these sulfur compounds must be eliminated. The process requires ...

The aromatic oil extracted from thyme leaves contains thymol and carvacol, which have preservative, antibacterial, and antifungal properties. Thyme is a bronchial antispasmodic that relaxes muscles in the respiratory tract, an effect that makes it a good treatment for bronchitis and whooping cough. Thyme also relaxes smooth muscles in the gastrointestinal tract and the uterus, making it effective as a digestive aid and reliever of menstrual cramps. 

Lukaszewicz et al. (2004) reported the oxidative properties of oil extracted from various flax cultivars. Linola cultivar (high LA), with the lowest content of linolenic acid, exhibited the highest conjugated diene values when heated... 

Enterprises which hold large volumes of waste PCBs, PCB-containing waste oils and disused pole-mounted transformers that contain PCB-containing insulation oils are building or planning to build treatment facilities on their own. It is essential for the government to assist and encourage their effort. For pole-mounted transformers and insulation oils extracted from these pole-mounted transformers, concerted actions will be taken in line with the efforts of electric power companies which store those PCB wastes. 

Laboratory studies with petroleum and petroleum fractions. The first report of microbial oxidation of sulfur heterocycles was published by Walker et al. (28). Using computerized mass spectrometry (MS) to analyze the residual oil extracted from aerobically-grown mixed cultures, they observed losses of 40% of the dibenzothiophenes and 50% of the naphthobenzothiophenes. They concluded that the sulfur-containing aromatics were approximately twice as resistant to microbial degradation as their hydrocarbon analogues.
