Na. Idris et al., CHEMICAL-COMPOSITION AND PHYSICAL-PROPERTIES OF SOFT (TUB) MARGARINESSOLD IN MALAYSIA, Journal of the American Oil Chemists' Society, 73(8), 1996, pp. 995-1001
Seven samples of domestic and imported Malaysian tub margarines were a
nalyzed for their fatty acid and triglyceride (carbon number) composit
ion, solid fat content, dropping and softening points, crystallization
temperature, polymorphic form, color, and textural attributes. Domest
ic margarines were formulated from palm oil or palm olein and palm ker
nel oil with a liquid oil but no hydrogenated oils, Two imported produ
cts contained hydrogenated palm oil product, which resulted in a high
level of beta' crystals, whereas the domestic nonhydrogenated products
contained more beta than beta' crystals. Crystal habit was related to
the fatty acid and triglyceride composition of the high-melting glyce
rides. Domestic products were firmer in texture, probably because they
were formulated to be sold in a tropical climate.
