Silicon dioxide had the best refining effect, with dephosphorization and deacidification rates of 95% and 42%, respectively, when the dosage was 30 g/kg at a squeezing chamber temperature of 130 °C. At the same time, the L* value of rapeseed oil increased by 21%, and the a* value decreased by 59%.
What is sprsp Technology in rapeseed oil refining?
Conclusions A new method of rapeseed oil preparation technology called SPRSP technology was investigated. Silicon dioxide, ascorbyl palmitate, activated clay and sucrose fatty acid ester were selected from nine materials with superior rapeseed oil refining ability.
What is synchronous pressing and refining of rapeseed oil?
A new method for rapeseed oil preparation named synchronous pressing and refining after solid-phase preadsorption technology was investigated. Rapeseed and adsorbents were first mixed evenly to form premixes, and the product oils were then obtained by direct pressing and filtering.
What is rapeseed oil preparation technology?
The present rapeseed oil preparation technology universally used is prepressing and leaching technology. It is a long-term process with high energy consumption and a large discharge of three wastes (wastewater, waste organic solvent and residue).
