A new method for rapeseed oil preparation named synchronous pressing and refining after solid-phase preadsorption technol. was investigated. Rapeseed and adsorbents were first mixed evenly to form premixes, and the product oils were then obtained by direct pressing and filtering. The phospholipid content, acid value, a* value, chlorophyll, carotene, polyphenol contents of crude oil increased, while L* and b* values decreased with increasing squeezing chamber temperature A moderate adsorbent dosage and temperature could improve the refining effects. Silicon dioxide had the highest dephosphorization and deacidification rates of 95% and 42%, resp., when the dosage was 30 g/kg at 130 °C. Activated clay decreased the chlorophyll and carotene contents by 75% and 38%, resp. Sucrose fatty acid ester had dephosphorization and deacidification rates of 67s% and 41%, resp. Ascorbic palmitate had a dephosphorization rate of 74% and retained polyphenols intactly. This technol. would not affect the oil yield and could decrease the peroxide value of rapeseed oil. It realized the simultaneous completion of pressing and refining with the advantages of a short preparation time and environmental sustainability. This study involved multiple reactions and reactants, such as Glyceryl monostearate (cas: 31566-31-1Name: Glyceryl monostearate).
Glyceryl monostearate (cas: 31566-31-1) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Name: Glyceryl monostearate
