The number of equilibrium stages required for rice bran oil extraction was theoretically determined, and it was shown that in the extraction process using hexane the number of ideal stages is lower than the number required when ethanol is used as solvent.
For instance, Sean et al. [44] have studied the quality of rice bran oil extraction with hexane and d-limonene solvents.
This shows that processes able to overcome the high acidity of RBO, may be a valuable tool to take advantage of this resource for the production of chemicals, also considering that from defatted bran further extraction of high-value molecules is possible [33].
In this paper, the phenolic compounds from wheat bran were extracted by ultrasound-assisted extraction technology.
Extraction for 4 h at 60 °C with an alkaline (pH 11.5) H2O2-solution (2·0%) and 2·0% wheat bran in the extractant yielded an alkaline extract containing 77% of the wheat bran total arabinose content, 65% of the total xylose content and 86% of the total non-cellulosic glucose content.
β-Glucan extraction from bran of hull-less barley was performed with an accelerated solvent extraction (ASE) technique and compared with ultrasound-assisted extraction (UAE), microwave-assisted extraction (MAE), and reflux extraction.
Here, we evaluate polymeric changes (chemical and physical) as a result of selected hydrothermal pretreatment conditions on destarched wheat bran using controlled polymer extraction methods.
In this study, extraction of rice bran oil from various brands of rice bran available in Sri Lanka has been studied and data necessary for extraction, equipment design and process predictions have been determined.
Briefly, 100 g of stabilized rice bran was placed into the SFE extraction vessel and extraction parameters were set at 600 bars pressure, temperature of 40°C and carbon dioxide flow rate of 30 g/min.
This study could successfully evaluate the influences of various conditions on the AX extraction from rye bran.
