Characterization of phospholipid reverse micelles in relation to membrane processing of vegetable oils

Antioxidant Properties of Chlorogenic Acid and Its Alkyl Esters in Stripped Corn Oil in Combination with Phospholipids and/or Water

“…In this context the TCNQ method has been used to measure the CMC of DOPC, that is, the concentration at which DOPC begins to aggregate into association colloids and, thus, the concentration at which an oil starts to behave as a multiphasic system. This technique has been found to be consistent with interfacial tension measurement, especially for phospholipids in bulk oil. , Figure shows that at low concentration in bulk oil, DOPC does not change the absorbance of TCNQ, which lies in a plateau, until a drastic increase is reached at 65 μM DOPC as determined by tangent-based calculation. This break corresponds to the CMC of DOPC in bulk oil and is assumed to be due to a charge transfer between TCNQ and phospholipids when they self-assemble in physical structures.…”

Characterization of phospholipid reverse micelles in nonaqueous systems in relation to their rejection during membrane processing

“…1) and the CMC of PL mixed micelles in oil was estimated to be 850 mg/kg (Table 1). Employing the same technique in our previous work, the CMC of PC in refined HOSF oil was reported to be 440 mg/kg (Subramanian, Ichikawa, et al, 2001). HPLC analysis of lecithin showed that major individual hydratable PL, namely PC, PI and PE were 13.6%, 8.5% and 13.7%, respectively.…”

“…However in the analogous model system (soy lecithin in refined SBO) studied, the CMC of mixed PL (850 mg/kg) was lower than the corresponding real system. The PC content in total PL was 23.6% in the model oil system while it was 5.7% in the real CSBO system (Subramanian, Ichikawa, et al, 2001) which could be the probable reason for the lower CMC of mixed PL in the model oil system.…”

Colloid-Enhanced Ultrafiltration of Canola Oil: Effect of Process Conditions and MWCO on Flux, Fouling and Rejections

“…It was reported that at the particular concentration of phosphatidylcholine (8,900 mg/kg), when the ratio of water to phosphatidylcholine was increased from 0.079 to 0.112, the size of micelles increased from 3.56 to 4.60 nm (Subramanian et al . ). Subramanian et al .…”
