The addition of monoacylglycerols also led to a change in the
polymorphic form of the crystals present in palm oil. The presence
of MP led to the formation of b-type crystals. When MBe was
added, peaks for b-crystals appeared and a sub-b transitional form
could also be observed, indicated by short spacings of, respectively,
4.6 and 3.9 Å. Adding 1% of fully hydrogenated palm-based monoacylglycerols
also caused the formation of b-crystals, despite coexisting
with a higher content of b’-crystals, since a relatively intense
peak for a short spacing of 4.2 Å can be observed.
