摘要

Continuous enzymatic interesterification in a stepwise temperature changing system is provided to produce oils and fats containing less than 30% of saturated fat without trans fats by reacting to mixed oil of soybean oil-derived extremely hardened oils and high-oleic acid sunflower oils at higher temperature than a melting point of the mixed oil and re-reacting to the mixed oil at lower temperature than the melting point of the mixed oil. A method for preparing oils and fats containing less than 30% of saturated fat comprises the following steps of: mixing soybean oil-derived extremely hardened oils and high-oleic acid sunflower oils; primarily reacting to the mixed oil in a continuous packed-bed reactor with lipase at 70°C for 3-15 minutes; and secondarily reacting to the mixed in the continuous packed-bed reactor with lipase at 60°C for 3-200 minutes. The mixing ratio of the soybean oil-derived extremely hardened oils and high-oleic acid sunflower oil is 1 to 9 or 9 to 1. The lipase is selected from the group consisting of: lipase derived from microorganism containing Rhizopus delemar, Mucor miehei, Alcaligenes sp., Aspergillus niger, Candida Antarctica, Candida cylindracea and Geotrichum candidum; lipase derived from plant containing seeds from soybean, manuka and castor bean; and animal pancreatic lipase.
