1. A method for enhancing palatability of a polyunsaturated fatty acid (PUFA) oil product to a human or companion animal comprising the steps of:
(a) obtaining a crude PUFA oil;
(b) degumming and/or refining the crude PUFA oil obtained in step (a) by feeding the crude PUFA oil through a short path evaporator (SPE) to obtain a degummed and/or refined PUFA oil; and
(c) deodorizing the degummed and/or refined PUFA oil obtained from the degumming and/or refining step (b) to obtain a deodorized PUFA oil; wherein
the yield of the deodorized PUFA oil after the deodorizing step (c) is no less than 85% of the crude PUFA oil started with at the step (a), and wherein
the deodorized PUFA oil after the deodorizing step (c) has a palatability score as measured by an animal food preference test which is at least 10 percentage points higher than the palatability score of the crude PUFA oil started with at the step (a).
