1. A method of increasing the in vivo hydrolysis rate of a cured oil coating having cross-linked fatty acids, wherein the method comprises the steps of (i) enriching one or more oils used to form the cured oil coating by adding one or more fatty acid ethyl esters to form an enriched oil, wherein the enriched oil comprises about 75% w/w or more of the one or more fatty acid ethyl esters, and wherein the enriched oil comprises at least 50% w/w polyunsaturated fatty acids and (ii) exposing the enriched oil to curing conditions to form the cured oil coating so that a number of polar hydroxyl functional groups are formed in the cured oil coating during curing that increases the polarity of the cured oil coating compared to what is formed during curing when the one or more oils are cured without the enriching step, thereby increasing the in vivo hydrolysis rate of the cured oil coating and providing the coating with a contact angle of less than 90°
