Abstract

Anemia is globally linked to dietary iron deficiency, potentially concerned by a shift from meat-based diets to plant-based ones with less bioavailable non-heme iron. This study compared the iron bioavailability of two commercial plant-based burgers (PBB1 and PBB2) with that of an animal-based burger (ABB). PBB1 and PBB2 contain 2.37 mg and 2.45 mg, respectively, while ABB contained 1.6 mg of iron per 100 g. The iron bioavailability (ng ferritin/mg protein) of PBB2 (5.98 ± 0.41) and PBB1 (4.70 ± 0.33) was higher than ABB (4.05 ± 0.29) as determined using a Caco-2 cell model. The main inhibitors and enhancers of iron bioavailability were also investigated. Phenolic compounds were found to increase iron bioavailability in the PBBs, suggesting they may not always act as antinutritional factors. Phytic acid content had no significant impact on iron bioavailability. There was a positive correlation between the antioxidant properties of the digested burgers and iron bioavailability. These findings suggest that PBBs can match or exceed the iron bioavailability of ABB, offering potential solutions for global nutritional challenges.

期刊介绍： Biophysical studies of foods and agricultural products involve research at the interface of chemistry, biology, and engineering, as well as the new interdisciplinary areas of materials science and nanotechnology. Such studies include but are certainly not limited to research in the following areas: the structure of food molecules, biopolymers, and biomaterials on the molecular, microscopic, and mesoscopic scales; the molecular basis of structure generation and maintenance in specific foods, feeds, food processing operations, and agricultural products; the mechanisms of microbial growth, death and antimicrobial action; structure/function relationships in food and agricultural biopolymers; novel biophysical techniques (spectroscopic, microscopic, thermal, rheological, etc.) for structural and dynamical characterization of food and agricultural materials and products; the properties of amorphous biomaterials and their influence on chemical reaction rate, microbial growth, or sensory properties; and molecular mechanisms of taste and smell. A hallmark of such research is a dependence on various methods of instrumental analysis that provide information on the molecular level, on various physical and chemical theories used to understand the interrelations among biological molecules, and an attempt to relate macroscopic chemical and physical properties and biological functions to the molecular structure and microscopic organization of the biological material.
