Abstract
A stabilized lipid composition of randomly interesterified triacylglycerols (TAGs) that includes, by weight of fatty acid components, long-chain polyunsaturated fatty acids (LC-PUFAs) having at least 20 carbon atoms and a degree of unsaturation of at least 4 and being present in a nutritionally beneficial amount but less than 5% by weight; and medium-chain saturated fatty acids (MC-SFAs) having six to fourteen carbon atoms and being present to promote absorption of the LC-PUFAs. The LC-PUFAs are mono-LC-PUFAs. Also, a nutritional product or infant food product that contains the lipid composition as a portion of the lipids therein, and methods to make such compositions and products.
Claims20
A stabilized lipid composition of randomly interesterified triacylglycerols (TAGs) comprising, by weight of fatty acid components:
- long-chain polyunsaturated fatty acids (LC-PUFAs) having at least 20 carbon atoms and a degree of unsaturation of at least 4 and being present in a nutritionally beneficial amount but less than 5% by weight;
- and
- medium-chain saturated fatty acids (MC-SFAs) having six to fourteen carbon atoms and being present to promote absorption of the LC-PUFAs;
- wherein the TAGs containing LC-PUFAs almost exclusively are mono-LC-PUFA.
The nutritional product of claim 7, wherein the lipids are present in an amount of 15 to 35% by weight of dry matter, with the lipid composition of claim 1 representing 5 to 50% of that amount.
An infant food which further comprises the nutritional product of claim 8 and one or more components of proteins, hydrolysed proteins, carbohydrates, vitamins and trace elements.
The infant food of claim 9 in dry form.
A process for the preparation of a lipid composition which comprises:
- interesterifying a mixture of (A) 1 to 20% of an oil that is rich in LC-PUFAs having a degree of unsaturation of at least 4 and (B) 80 to 99% of an oil that is rich in MC-SFAs at a sufficient temperature ad for a sufficient time in the presence of a catalyst to form a product where fatty acids are randomly distributed on a glyceryl backbone;
- washing the product to remove alkaline and soap residues;
- refining the product by removing secondary products of the interesterification and traces of soap from the washed product;
- and
- deodorizing the refined product to obtain a deodorized, decolorized, stabilized lipid composition.
The process of claim 11 wherein the product is refined by contacting the washed product with an adsorbent for a time sufficient to adsorb secondary products of the interesterification and traces of soap from the product, and then separating the adsorbent from the product.
