A frequency sweep test and creep test for LH and control butter
were analysed according to Vithanage, Grimson, and Smith (2009)
with slight modification, using a HAAKE MARS III rotational
rheometer (Thermo Scientific, Germany) with parallel plate fixtures.
The instrument was set to the zero gap position with the
lower plate temperature set at 25 C. A 3 mm gap was then set
as the starting position upon sample loading. The loaded sample
was allowed to equilibrate for 30 min prior initiation of run.
