Measurements made at temperatures from 10-40 deg C showed that at 10 deg C SFC values were consistently higher than SFI. But, over the 21.1-40 deg C temperature range, values were comparable by both methods. The effect of emulsifiers in commercial spread oils on SFI values was investigated. The presence of common margarine/spread emulsifiers, including lecithin, mono/diglycerides, and monoglyceride, induces errors into SFI determination by dilatometry. However, the differences were not statistically significant. |
