Hexane, the common solvent for extraction of edible oils from seeds is no more considered safe due to the presence of solvent in oil and also solvent vapour, a hazardous air pollutant. We have carried out the experiments with bahera (Terminalia bellerica Roxb) and flax seed (Linum usitatissimum ) oil as these oils are highly used in food for their nutraceutical values. The extraction of edible ...
abstract: the object of this study is to extract the oil from millets and evaluate the chemical properties of the extracted oil. commercial millet oil was obtained by cold solvent extraction adopting soxhlet procedure. quantitative and qualitative tests concerned with the non-saponifiable matter, fatty acid composition, phosphorus content representing total phospholipids, refractive index, pero...
evaluation of solvent extraction efficiency –chemical analysis of the oil extracted from apple seeds
oils and fats are substances that are important nutritionally and have important role and impact on human health. energy consumption and preservation in respect of food industry and the increase in the world population and search for new sources of oils and fats to full fill the need of the society particulary the nutritional requirements have introduced this research topic. therefore aim of th...
in reality, most structures involved in geotechnical engineering are three dimensional in nature, and although in many, plane strain or axisymmetric approximations are reasonable, there are some, for which 3-d treatment is required. the quantity of data, and the size of the various vectors and matrices involved in such analysis, increase dramatically. this has sever implications for computer r...
Nowadays, viable and cost-effective methods play a vital role in hydrocarbon exploration up to the point that geoscientists cannot rule out the importance of the passive seismic method (PSM) in oil exploration operations. This method is based on seismic energy, which has a natural source. This study focuses on seismic energy anomaly of 1-6 Hz. Some researches show that spectral and polarization...
ii abstract the legend of human being’s refulgence was distorted completely in the age of modernity. this new age, had some drastic negative effects, besides its positive qualities. one significant negative effect of it was the emergence of neurosis in human beings. aldous huxley’s brave new world was one of the novels of the 02 th century that contained the prophecy of criticizing ...
Abstract : In-situ process is one of the biodiesel production methods in which seeds are used directly in the reaction without oil extraction. The objective of this research is to optimize the biodiesel production conditions for the in-situ reaction using tomato seeds as a feed. The effects of reaction parameters such as molar ratio of oil to alcohol and catalyst to oil weight percent ratio on ...
Tropical peatlands store globally significant quantities of carbon and are ecologically culturally important, but little is known about their vulnerability to oil gas exploration extraction. Here, we analyse the exposure tropical activities petroleum industry review what sensitivity these activities. We find that 8.3% (107,000 km 2 ) total area overlaps with a 30-km buffer around infrastructure...
the oil content of the wax produced in a dewaxing process is the key economic parameter thatshould be reduced as much as possible. some factors such as the type of solvents, cooling rate,temperature, and solvent to oil ratio influence the dewaxing process. due to the fact that crude oildiffers from place to place and since the operational conditions for wax extraction vary for differenttypes of...
In this study, moisture content, free fatty acids, peroxide, iodine value, unsaponifiable matter, saponification value, fatty acid composition and tocopherol contents of wheat germ oil obtained by SC-CO2 extraction and cold press technology were investigated. Moisture, free fatty acid (FFA), peroxide value, iodine value, unsaponifiable matter and saponification value of cold pres...
