evaluation of ethanol and 2-propanol for rapeseed oil extraction in Zimbabwe

The current process to extract oil from oilseeds such as rapeseed or sunflower, involves three main steps: a) preparation of the seeds including conditioning and pressing, b) solvent

The results show that the ethanol extraction of rapeseed kernels followed by cooling separation of obtained miscella results in a high quality crude decanted oil (notably free from free fatty acids,

The current process to extract oil from oilseeds such as rapeseed or sunflower, involves three main steps: a) preparation of the seeds including conditioning and pressing, b)

This present study was designed to evaluate the performances of five alternative solvents (alcohols: ethanol, isopropanol and terpenes: d -limonene, α-pinene, p -cymene)

Relative solubility of major triglycerides, sterols and tocopherols present in rapeseed oil were assessed with COSMO-RS3 in 2-methyltetrahydrofuran (MeTHF), cyclopentylmethylether

Download Table operating conditions from publication: Evaluation of ethanol and 2-propanol for rapeseed oil extraction The current process to extract oil from oilseeds such as rapeseed or

Rapeseed oil extraction was carried out using ethanol (92 wt.% or 96 wt.%), isopropanol (84 wt.% or 88 wt.%) or hexane (as reference). Results show that hydroalcoholic extraction increased meal protein content by 13%

The cellulosic materials are generally been used for the production of bio ethanol. The present paper reports the effect of key reaction parameters such as Ethanol/oil ratio, reaction time,

This study investigated alternative solvents: ethanol and isopropanol, to replace hexane and enhance the quality and value of oil and meal. Rapeseed oil extraction was carried out using ethanol

Oxidative-stability and nutritional-enhancement of rapeseed oil are positively related to phenolic content. This study developed a novel approach to improve oil quality by extracting

Enzyme-assisted oil extraction is most commonly carried out in wet conditions to ensure high enzymatic activity: the seeds are dispersed in water at ratios of 1:2–1:12, and the enzyme is

SUMMARY Heating the rapeseed prior to the oil extraction is conducted to increase the oil yield but it can also induce changes of various components of the seed. These changes may affect the composition of the volatile and non

Rapeseed oil extraction was carried out using ethanol (92 wt.% or 96 wt.%), isopropanol (84 wt.% or 88 wt.%) or hexane (as reference). Results show that hydroalcoholic extraction increased meal protein content by 13% compared to

COSMO-RS3 simulation was conducted with some of the major triglycerides (TAGs) and micronutrients (tocopherols and sterols) occuring in rapeseed oil in order to evaluate their

Background: Rapeseed oil is the most widely consumed vegetable oil globally. However, the key aroma-active compounds of rapeseed oil and their changes during storage

The extraction yield of oil from rapeseed cake obtained by super-critical CO2 extraction (SCO2E), subcritical R134a/butane extrac-tion (SRBE), and hexane extraction (HXE) is shown in Table 4.

One of the methods that enables a reduction in the cost of biodiesel is simultaneous oil extraction and transesterification . During this process, alcohol acts as both an oil

Feb 1, 2004Reaction temperature was set at 300 °C, and methanol, ethanol, 1-propanol, 1-butanol or 1-octanol was used as the reactant. The results showed that transesterification of
