Linseed, Baru, and Coconut Oils: NMR-Based Metabolomics, Leukocyte Infiltration Potential In Vivo, and Their Oil Characterization. Are There Still Controversies?

Different fatty acid proportions produce potential inflammatory and metabolic changes in organisms. However, the evidence for how each fatty acid mediates the metabolic pathway, and its lipid stability remains controversial. To resolve this controversy, the present study investigated the metabolic effects of cold-pressed linseed (LG), coconut (CG), and baru (BG) oils in comparison to those of soybean oil (SG) in mice, in terms of their oil characterization and stability.

Antibacterial potencial of 12 Lichen species.

Resistant bacterial infections are a major public health problem worldwide, which entails the need to search for new therapeutic agents. In this context, lichens stand out, provided that they are producers of structurally diverse compounds that have attractive biological properties, including antimicrobial activity. Thus, extracts of 12 lichen species were prepared and their potential to inhibit the growth of 5 bacterial strains was evaluated in this work.

Sodium quantitation in soft drinks: A rapid methodology by qNMR.

High sodium dietary intake has a positive association with an increase in blood pressure and can be correlated with risk factors of disease. Considering that the World Health Organization recommends a sodium intake lower than 2 g day for adults, the hidden sodium content in processed foods is an important factor that compromises the assessment of a healthy diet. Accordingly, the present paper aimed to quantitate the sodium content of conventional soft drinks and their diet versions using nuclear magnetic resonance spectroscopy as a quantitative analytical technique ( Na qNMR).

NMR-based and chemometric approaches applicable to adulteration studies for assessment of the botanical origin of edible oils.

The health benefits of edible oils, especially promoted by ω3 and ω9 fatty acids, have been associated with their botanical origin. In order to investigate fatty acid profiles, we assessed Brazil nut, chia, linseed, sesame (toasted and raw), and soybean oils by H nuclear magnetic resonance (H NMR) and chemometrics. PCA plots revealed important relationships between chemical composition and botanical origin for reference and commercial samples.
