The aim of this study was to use proximate chemical composition, macro and trace elements, fatty acid profile and stable isotopes as traceability tools to assess geographic origin and seasonality of croaker (Micropogonias furnieri). Croaker from Parnaíba contained higher ash in July and lower fat content than croaker from Santos. In contrast, croaker from Santos had statistically higher proportion of 16:1n-9þ16:1n-7, 20:1n-11, 20:1n-9, MUFA and n-3/n-6 ratio than croaker from Parnaíba. Concerning seasonality, croaker caught in July had significantly higher amounts of 14:0, 15:0, 16:1n-9þ16:1n-7 and saturated fatty acids than fish caught in December. Concerning elements, significant differences were also detected between seasons for Cl, Ca, Fe, Sr and S, whereas differences between geographic origins were only observed with K. d13 C and d15N were statistically different between geographic origins, whereas differences between seasons were only detected in d15N ratio of croaker from Santos. Fatty acids, minerals and stable isotope are effective methods to trace geographic origin and seasonality of croaker. Nonetheless, further investigation is still required with larger samples of croaker to enable the implementation of fatty acids, elements or stable isotope as authenticity tools by food control agencies. |

This work compared the mechanisms of adsorption of carotenes from hybrid palm oil onto two kinds of bleaching earths widely used by industrial refiners (acid-activated and neutral). First, it was performed a deep characterization of adsorbent surfaces: acid activated adsorbent showed micropore volumes twice larger than the neutral. FTIR analysis of adsorbent after adsorption demonstrated that active site was Si?O?Si for both adsorbents. However, comparison of peak shapes suggested distinctive interactions between adsorbent/adsorbate for each adsorbent. Latterly, an extensive kinetic and equilibrium study was performed. Kinetic data were in accordance with pseudo-first and pseudo-second-order models. Adjusting to the intra-particle diffusion model evidenced more than one mechanism controlling the adsorption process. Equilibrium data demonstrated adsorption is only favorable at low carotene concentration at liquid phase for acid adsorbent (lower than 1 mg/mL). For neutral adsorbent, it was not clearly observed a favorable region with the studied conditions. The acid adsorbent could adsorb more carotenes per adsorbent weight than neutral. Finally, neutral adsorbent showed higher heterogeneity of interaction between adsorbate and adsorbent than the acid, especially at low adsorbent coverages. |
