Abstract
Fatty acid profile of lipids in animal origin products (AOP) for human food regimen plays an important role for its effects on consumer health. Over time ‘lard’ has played an useful function in the composition of a ration for human diets. A revaluation of biochemical effects of ‘lard ', as a source of biomolecules with nutritional and extranutritional properties, is in progress. The Autochthonous Genetic Types, especially ancient types (AAGT), can be considered in future a particularly useful source of this AOP. 'Casertana' pig, known since ancient times, deserves AAGT title. The study was carried out on 'fresh lard' taken at the level of 4th ÷ 6th lumbar vertebra from 50 ‘Casertana’ pigs (21 castrated males and 29 females) bred at Experimental Station of ConSDABI (Circello, Benevento). The acidic fraction was extracted by Folch method and analyzed, as methyl esteres, by gas-chromatography. The acidic fraction considered consists of: palmitic, palmitoleic, margaric, eptadecenoic, stearic, oleic, C18:1 cis,12, linoleic, γ-linolenic and linolenic fatty acid and CLA, the more representative is C18:2 cis9, trans11 and the other 6 isomers were detected in traces. The effect of sex, year and month of slaughtering (covariates), age and refrigerated carcass weight was always significant (P<0.03 ÷ 0.0002) on all fatty acids as well as on ‘atherogenic’ and ‘thrombogenic’ indices. Therefore, in evaluating the utilization of ‘fresh lard’ from a health point of view for human food, it is possible to define the models of optimization of lipidic profile, especially in a innovative vision of ‘molecular’ gastronomy.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
