Separation and quantitation of serum beta-carotene and other carotenoids by high performance liquid chromatography.

Journal of Lipid Research, 1984
We describe a specific assay for serum provitamin A (alpha- and beta-carotene) by high pressure liquid chromatography (HPLC). The system separates alpha- and beta-carotene in 7.4 min using a C18 muBondapak, 10-micron particle size column with a mobile ...

Biobased Polyurethane Films Based on Andiroba (Carapa guianensis) and Buriti (Mauritia flexuosa) Oil Polyols

Journal of Applied Polymer Science, EarlyView.
Polyurethane films were prepared from andiroba (Carapa guianensis) and buriti (Mauritia flexuosa) oil‐derived polyols, emphasizing their potential as bio‐based materials. UV–Vis analysis indicates the retention of carotenoid‐related chromophoric features within the polymer matrix.

Enhancing Meat Quality Through Dietary Fiber: Insights Into the Gut Microbiota‐Derived Short‐Chain Fatty Acids‐Muscle Axis

Animal Research and One Health, EarlyView.
Dietary fiber (DF) modulates meat quality through the gut‐muscle axis by reshaping gut microbiota, improving intestinal integrity, reducing inflammation, and regulating muscle metabolism. These mechanisms influence muscle fiber characteristics and post‐mortem biochemistry, thereby enhancing tenderness, juiciness, color, flavor, and nutritional value of
