Abstract
A fat continuous stick having up to 80% of a fat containing less than 10% trans fatty acids prepared by a process comprising the steps of selecting a structuring amount of an interesterfied hardstock fat to make a stick product, combining the hardstock to form a fat phase, introducing an aqueous phase and the fat phase into a scrapped surface heat exchanger to form a cooled emulsion having an exit temperature of less than 20.degree. C., then passing the cooled emulsion into a crystallizing unit (C-unit) having an exit temperature of C-unit greater than the exit temperature of the emulsion and having a shear rate of less than 1800 rpm to aid in forming a finer dispersion and to initiate crystallization in the cooled emulsion. The emulsion with the fat crystals is then introduced into a second heat exchanger unit having a temperature range of at least 2-8.degree. C. below the exit temperature of the emulsion from the first exchanger unit wherein the residence time of the process is less than ten minutes. The hardstock fat is interesterfied as described herein.
