Abstract
There are provided polyunsaturated fatty acids-containing oils/fats or triglycerides with high digestion and absorption properties and resistance to oxidative damage, which are suitable for applications in fields such as modified milk for infants, food products and healthy foods and/or supplements, produced by transesterification of polyunsaturated fatty acids-containing oils/fats or triglycerides with vegetable oils/fats or triglycerides using 1,3-position specific type lipases.
Claims30
A production process for a transesterified oil/fat or triglyceride, by transesterification of 50-100 parts by weight of one or more fungus-produced oils/fats or triglycerides containing at least 20% of polyunsaturated fatty acids containing 20 or more carbons and two or more double bonds and 0-50 parts by weight of one or more vegetable oils/fats or triglycerides, using a 1,3-position specific type lipase.
A transesterified oil/fat or triglyceride containing at least 20% of polyunsaturated fatty acids containing 20 or more carbons and two or more double bonds, and which contains at least 40% of triglycerides with one residue of polyunsaturated fatty acids containing 20 or more carbons and two or more double bonds in the molecule and/or no more than 4.0% of triqlycerides with 3 residues of the same polyunsaturated fatty acids containing 20 or more carbons and two or more double bonds.
An oil/fat or triglyceride containing at least 20% of arachidonic acid, and which contains at least 40% of triglycerides with one residue of arachidonic acid in the molecule and/or no more than 4.0% of AAA.
An oil/fat or triglyceride containing at least 20% of dihomo-γ-linolenic acid, and which contains at least 40% of triglycerides with one residue of dihomo-γ-linolenic acid in the molecule and/or no more than 4.0% of DDD.
An oil/fat or triglyceride containing at least 20% of mead acid, and which contains at least 40% of triglycerides with one residue of mead acid in the molecule and/or no more than 4.0% of MMM.
A production process for a transesterified oil/fat or triglyceride, containing polyunsaturated fatty acids containing 20 or more carbons and two or more double bonds and one or more medium-chain fatty acids as constituent fatty acids, by transesterification of 50-100 parts by weight of one or more fungus-produced oils/fats or triglyceride containing at least 20% of polyunsaturated fatty acids containing 20 or more carbons and two or more double bonds and 0-50 parts by weight of one or more medium-chain fatty acid triglycerides (ZZZ), using a 1,3-position specific type lipase.
A transesterified oil/fat or triglyceride containing at least 1 wt % of each of a triglyceride containing arachidonic acid (A) and medium-chain fatty acid (Z) as constituent fatty acid, ZAZ, wherein ZAZ is a a triglyceride with 2 residues of medium-chain fatty acid and one residue of arachidonic acid, wherein arachidonic acid is bound to the position 2, and ZZA, wherein ZZA is a a triglyceride with 2 residues of medium-chain fatty acid and one residue of arachidonic acid, wherein arachidonic acid is bound to the position 1 or 3.
