Liquid-liquid equilibrium data are presented for extraction of odoriferous compounds (hexanal, heptanal, butyric acid, valeric acid, caproic acid, and caprylic acid) from refined soybean oil using dimethyl sulfoxide. On the other hand, Fig 2 shows deodorized o, owed that, after deodorization step, FFA reached t, ent in sunflower oil samples taken from the neutralizing, g neutralizing and degumming, bleaching and, . Changes of, Total Tocopherol and tocopherol Species dur. The objectives of the present paper are to study, evaluate and optimize, as far as possible, independent variables involved in the process (nitrogen flow, The influence of the free fatty acid concentration in the gas inside the continuous deodorizer in continuous physical refining was studied and a hypothesis was formed to explain the results: In a continuous process of deacidification by distillation of free fatty acids at low pressure (2 - 3 mbar), high temperature (180 – 260 ºC), with stripping gas, initial free fatty acid content of oil ≤ 7.4%, The production of Malaysian palm oil is expected to increase 20% per year for the next 5 yr. 10 number were found to be independent of the oil sample size and airflow rate, and their mean values for soybean oil were calculated to be −3.12 × 10−2 °C−1 and 2.05, respectively. ; Lo´pez-Herna´ndez, J.; Paseiro-Losada. –Deodorization–Response surface methodology (RSM)– An alternative two-step deodorization is described. It is considered to have Also, it requires wintering process, to remove waxes from the oil (this it means a higher industrial cost). The effect of chemical refining on oil stability index of sunflower oil and other quality attributes free fatty acids, total tocopherols, colour and was investigated. Furthermore, the linear model was selected as the best model to describe the variations of TOTOX value and peroxide value during the deodorization process. a temperature range of 210–220°C, and deodorization time of 70–120min were defined. Low quantities of the oil were found in cosolvent-rich phases, and very poor solubility occurs for the system containing oil plus dimethyl sulfoxide plus water. chemicals and solvents used were of analytical grade. Steam (physical) refining deodorizer for Malaysian palm oil, New possibilities in California olive oil. Oils neutralized by Ca(OH)2, MgO and Na2SiO3 had lower FFA (free fatty acid) than degummed oil and oil neutralized by NaOH and also had better oxidative stability suggesting that they could be more effective in producing a high quality oil. This method, besides accomplishing the beneficial effects of the conventional industrial thermal treatment, leads to an enrichment of some important minor compounds (polyphenols and phosphatides) in the resulting oil.
