Abstract

Abstract : The effect of a diet enriched with mullet bottarga on the lipid profile (total lipids, total cholesterol, unsaturated fatty acids, α-tocopherol, and hydroperoxides) of plasma, liver, kidney, brain, and perirenal adipose tissues of healthy rats was investigated. Abstract : The effect of a diet enriched with mullet bottarga on the lipid profile (total lipids, total cholesterol, unsaturated fatty acids, α-tocopherol, and hydroperoxides) of plasma, liver, kidney, brain, and perirenal adipose tissues of healthy rats was investigated. Rats fed a 10% bottarga enriched-diet for 5 days showed body weights and tissue total lipid and cholesterol levels similar to those of animals fed control diet. Univariate and multivariate results showed that bottarga enriched-diet modified the fatty acid profile in all tissues, except brain. Significant increases of n-3 PUFA, particularly EPA, were observed together with a 20:4 n-6 decrease in plasma, liver, and kidney. Perirenal adipose tissue showed a fat accumulation that reflected the diet composition. The overall data suggest that mullet bottarga may be considered as a natural bioavailable source of n-3 PUFA and qualify it as a traditional food product with functional properties and a potential functional ingredient for preparation of n-3 PUFA enriched foods.
