The invention discloses a synthesized
breast milk fat substitute product from
mixed fatty acid under an enzymatic condition in
microwave and a method for preparing the
breast milk fat substitute product. The method includes respectively arranging molecular sieves and saturated
salt solution in closed containers to control the activity of water; mixing
olive oil with free
fatty acid,
coconut oil and
algae oil with one another, mixing the
olive oil with the free
fatty acid, the
coconut oil, the
algae oil and triacylglycerol of
palmitic acid with one another in the same reaction flasks and respectively arranging the reaction flasks and
filter paper with
lipase in the various closed containers and balancing the reaction flasks and the
filter paper at the room temperatures; arranging substrates and the
lipase in screwed glass bottles, closing the screwed glass bottles, carrying out enzymatic transesterfication reaction in constant-temperature
water area shaking tables and
microwave reactors, separating reaction
grease by means of reduced-pressure
distillation and refining the
grease to obtain the
breast milk fat substitute product. The
olive oil with the free
fatty acid is purified by the aid of a
urea adduction process. The olive oil with the free fatty acid, the
coconut oil, the
algae oil and the triacylglycerol of the
palmitic acid are used as the fatty enzymatic transesterfication substrates. The breast
milk fat substitute product and the method have the advantages that the final
reaction product contains abundant
DNA (docosahexenoic acid), and the content of the
palmitic acid on sn-2 sites of the breast
milk fat substitute product is relatively high and can be assuredly equivalent to the content of palmitic acid on sn-2 sites of natural breast
milk fat.
