DSC heating thermograph and darkfield optical micrographs of milk CPE suspension. (A) Representative DSC heating thermograph of milk CPE (0.5 mM) dispersion in HEPES buffer. Scan rate, 10 degrees/h; scan range, 20–80 °C. (B) Milk CPE was hydrated at 60 °C as described in Materials and Methods. Darkfield images were acquired at room temperature (22 °C). Milk CPE exhibits amorphous lipid aggregates but needle and helical structures were also observed at low frequency. Bar, 50 μm.
