Application No. 08/491,769
14. A fat continuous spread having from about 30 to
about 80% fat and having a trans fatty acid level of less than
about 10%, prepared by a process in a production line to
shorten residence time and increase a crystallization rate,
the process comprising the steps of:
(1) selecting a structuring amount of a hardstock fat to make
a spread product, the hardstock fat having a level of
trans fatty acids not exceeding 10% and prepared by
randomly interesterifying a mixture containing 30-75 wt.%
of an oil (i) in which at least 20% of the fatty acids
residues consists of linoleic acid and 25-70 wt.% of a
fat (ii) in which at least 80% of the fatty acid residues
is saturated and has a chain link of at least 16 carbons
and then fractionating the interesterified mixture to
obtain an olein fraction having a solid fat content of:
N = 22-80, N = 8-60, N = 1-25, N = 0-15;10 20 30 35
(2) selecting an amount of an oil which is liquid at
room temperature selected from the group consisting
of soybean oil, sunflower oil, fish oil, rapeseed
oil, coconut oil and mixtures thereof;
(3) combining the hardstock fat of step (1) and the
liquid oil of step (2) to form a fat phase;
(4) preparing an aqueous phase to combine with the fat
phase of step (3) to provide a fat continuous
emulsion having less than 80% fat in the total
composition;
(5) introducing the fat continuous emulsion into a
scraped surface heat exchanger unit to cool the
emulsion to an exit temperature of less than the
temperature needed to transform a substantial amount
of the fat crystals into an alpha phase to form a
partially crystallized cooled emulsion;
(6) passing the partially crystallized cooled emulsion
into a crystallizing unit for a shortened residence
time sufficient to substantially convent the alpha
