Special Issue Information

Dear Colleagues,

Functional foods are still gaining widespread consumer interest, mainly due to their beneficial effects on humans. Their actions are primarily connected with the content of bioactive compounds. These compounds are mainly plant secondary metabolites (e.g., flavonoids, carotenoids, and phenolic acids) utilized in recipes as pan extracts or sometimes as pure compounds. However, primary plant metabolites and sometimes compounds from animal sources (e.g., selected peptides, vitamins, minerals, and fatty acids), as well as compounds from other sources such as single cells (e.g., yeasts, bacteria, and algae) can be considered functional ingredients. Biologically active compounds demonstrate various positive physiological and immunological functions. Some act as antioxidant agents and thus can diminish the risk of various diseases, including cancer. Others stimulate defense mechanisms, prevent widespread damage, or enhance cell repair. One of the limitations of the application of functional ingredients is their stability, but other main challenges include finding optimal concentrations and recipes.

This Special Issue of Molecules aims to bring together the latest knowledge, ideas, considerations, and overviews on bioactive compounds that can be found in functional foods. We will highly appreciate contributions related to the identification and roles of bioactive functional food constituents, as well as all aspects of the challenges mentioned above. Original research and review articles on the enhancement of foods with functional, biologically active ingredients are also welcome.

Supplementing fish oil is one of the strategies to reduce the risk of cardiovascular disease, the leading cause of death around the world. Contradictorily, fish oil may also contain trimethylamine-N-oxide, a recently emerged risk factor for cardiovascular disease, as well as one of its precursors, trimethylamine. A method suitable for routine quantification of trimethylamine-N-oxide and trimethylamine in fish oil with a quick and easy liquid extraction without derivatization has been developed. Liquid chromatography with tandem mass spectrometry detection was employed along with a zwitterionic hydrophilic interaction liquid chromatography column and a gradient elution with eluents containing 50 mmol/L of ammonium formate. An internal standard (triethylamine) was used for quantification by mass spectrometry with an external calibration. The assay proved high linearity in the ranges of 10 to 100 ng/mL and 100 to 1000 ng/mL for trimethylamine-N-oxide and trimethylamine, respectively. The lowest limit of quantification was determined to be 100 µg/kg for trimethylamine and 10 µg/kg for trimethylamine-N-oxide, with the limit of detection at 5 µg/kg and 0.25 µg/kg, respectively. Accuracy ranged from 106–119%. Precision was below 7% the relative standard deviation for both analytes. The method was successfully applied for the determination of trimethylamine-N-oxide and trimethylamine contents in nine commercially available liquid fish oils and three commercially available fish oil capsules, showing that trimethylamine and trimethylamine-N-oxide are not present in highly refined fish oils.
