ABSTRACT:
A process for producing hard fats is disclosed. The process involves reacting a 1,3-specific lipase with a mixture of 23-48% palmitic acid, 6-25% lauric acid and 0.5-5% behenic acid or its ester with a monohydric or polyhydric alcohol. The palmitic acids include: palm oil, fractionated palm oil and hardened palm oil. The lauric acids include: palm kernel oil, coconut oil, babassu oil and fractioned oil and hardened oil obtained from the palm kernel, coconut or babassu oil. The lipase is preferrably obtained from Rhizopus, Aspergillus, Mucor, pancreas and rice bran.
