Spreadability and hardness of butter are two inversely related
parameters which affect the textural behaviour of the product.
These characteristics depend on many interrelated factors, such
as the solid fat content, the fatty acid composition of butter and
the functionality of the fat crystal network (Rønholt, Mortensen,
& Knudsen, 2013). Fig. 1 shows the solid fat content of milk fat
as a function of temperature for control and LH-butter samples.
Both samples showed comparable (P > 0.05) trend in the relationship
between solid fat content and temperature, showed that both
samples were cooled under similar rate. There was a slow decrement
in solid fat content from 20 C to 0C while a drastic
decrease in solid fat content from 0 C to 10C for both LHbutter
and control. Such a drastic decrease is desirable to produce
a butter that has good spreadability especially between the recommended
solids fraction of 20–40%
