Influence of extraction technology on rapeseed oil functional
Introduction Rapeseed is one of the most important oil crops, ranking as the second leading source of edible oil production in the world. 1 Rapeseed oil contains
Rapeseed proteins for technical applications: Processing
Conventionally, oil extraction from rapeseed is achieved by screw-pressing, either by expeller pressing (full-pressing) or by pre-pressing of the seeds, followed by solvent extraction. Oil contents in the resulting press cakes are in the range of 5 %?0 % (full-press) or 15 %?8 % (pre-press) ( Kemper, 2005 ).
Effect of Different Extraction Methods on Quality
This study reports the effect of roasted pretreatment combined with screw press, hydraulic press, and Soxhlet extraction methods on various quality indexes of rapeseed and flaxseed oils, including the oil yield, sensory indexes (color, smell, clarity, viscosity, and colligation score), physicochemical properties (acid value, pScienceDirect
Evaluation of alternative solvents for improvement of oil
The conventional process utilizes only mechanical extraction (pre-press yields about 60% of oil) or solvent extraction, or even combines both of them [1].In order to become edible, the crude vegetable oil, a mixture of pressed and extracted oil, must undergo further refining processes for elimination of impurities and contaminants, in order to guarantee physicochemical and organoleptic
Cold pressed rapeseed (Brassica napus) oil ScienceDirect
Rapeseed oil is recognized as a healthy oil due to its attractive fatty acid profile, which is high in monounsaturated fatty acids (MUFAs) and polyunsaturated fatty
Effect of Different Extraction Methods on Quality ... - Hindawi
The contents of linolenic acid and vitamin E in rapeseed and flaxseed oils extracted from screw press method were higher. In particular, the linolenic acid content of cold-pressed rapeseed oil extracted by screw press increased by 1.50%?3.80% compared with other treatment groups.
Rapeseed (Brassica napus): Processing, Utilization,
For instance, aqueous extraction of rapeseed oil (using a slurry composed of 1.5:10 water– kernel) gave an oil of high quality (low acid and peroxide content)
Value of hydroalcoholic treatment of rapeseed for oil
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 hexane extraction, but without significant influence of alcohol and water content.
An advanced aqueous method of extracting rapeseed oil
Because of concern about environment, health, and cost, research into the production of rapeseed oil by aqueous extraction has been promoted. The
Polyphenol and Protein Extraction from Rapeseed Stems
Oil press cake is the residue obtained after the oil extraction from oilseed by pressing. Press cake usually contains 1?% residual oil and it is rich in proteins. For instance, in the rapeseed press cake, the protein content can reach 30% (Table 1). Therefore, most of the oil cakes are used as valuable food for animal feed.
