“…Following a valorization approach, As, Hg, Cd, and Pb have recently been identified in different side streams of several fish species [ 8 , 20 , 37 , 38 , 39 , 40 , 41 ]. Other undesirable compounds, such as PCBs and dioxins, can be found in the fatty tissues of fish, and their levels in the hydrolysates studied here are believed to be low due to the removal of lipids in the hydrolysis process [ 22 ].…”

Information on the bioaccessibility of minerals is essential to consider a food ingredient as a potential mineral fortifier. In this study, the mineral bioaccessibility of protein hydrolysates from salmon (Salmo salar) and mackerel (Scomber scombrus) backbones and heads was evaluated. For this purpose, the hydrolysates were submitted to simulated gastrointestinal digestion (INFOGEST method), and the mineral content was analyzed before and after the digestive process. Ca, Mg, P, Fe, Zn, and Se were then determined using an inductively coupled plasma spectrometer mass detector (ICP-MS). The highest bioaccessibility of minerals was found in salmon and mackerel head hydrolysates for Fe (≥100%), followed by Se in salmon backbone hydrolysates (95%). The antioxidant capacity of all protein hydrolysate samples, which was measured by Trolox Equivalent Antioxidant Capacity (TEAC), increased (10–46%) after in vitro digestion. The heavy metals As, Hg, Cd, and Pb were determined (ICP-MS) in the raw hydrolysates to confirm the harmlessness of these products. Except for Cd in mackerel hydrolysates, all toxic elements were below the legislation levels for fish commodities. These results suggest the possibility of using protein hydrolysates from salmon and mackerel backbones and heads for food mineral fortification, as well as the need to verify their safety.

Fast gas chromatography (GC) has taken relevant position in separation science. The term fast GC clearly indicates an analytical approach characterized by the best resolving power in the last amount of time. Numerous approaches have been developed and applied to achieve high‐speed analysis in food field. Nevertheless, interest in the development and implementation of fast GC methodologies continues to increment. For a successful application, it is necessary to take in mind some key theoretical and practical concepts. Great attention has been dedicated to basic principles as well as different fast GC approaches. In such respect, the strong and weak points of micro‐bore and short capillary column, vacuum‐outlet conditions, and resistive heating have been discussed in detail. Finally, fast GC applications in food sector, grouped in fast GC analysis (3–15 min), very fast GC analysis (1–3 min), and ultra‐fast GC analysis (<1 min) have been reported.
