Comparative study of total lipids extraction methods in vegetable and animal samples

Abstract

<p>In recent years several researchers have conducted studies comparing total lipids extraction methods, to find the most efficient method. The objective of this work<strong> </strong>was to study four different total lipids extraction methods in soybean crumbs and chicken thigh hillbilly with solvents of different degrees of toxicity and polarity (n-hexane, n-hexane-isopropanol, chloroform, methanol and ethanol). The study showed that the Soxhlet method, using ethanol as solvent was more efficient in the total lipids extraction present in soybean crumbs (5.38%), but not significantly different (p ≤ 0.05) for organic chicken thigh (3.35%), among the methods. The Bligh & Dyer cold method was the most efficient for the soybean crumbs.</p><p> </p><p>DOI: http://dx.doi.org/10.14685/rebrapa.v1i2.19</p>
