Bioaccessibility and bioactive potential of different phytochemical classes from nutraceuticals and functional foods. Front Nutr 2023; 10:1184535. [PMID: 37575331 PMCID: PMC10415696 DOI: 10.3389/fnut.2023.1184535] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2023] [Accepted: 06/15/2023] [Indexed: 08/15/2023] Open
Abstract
Nutraceuticals and functional foods are composed of especially complex matrices, with polyphenols, carotenoids, minerals, and vitamins, among others, being the main classes of phytochemicals involved in their bioactivities. Despite their wide use, further investigations are needed to certify the proper release of these phytochemicals into the gastrointestinal medium, where the bioaccessibility assay is one of the most frequently used method. The aim of this review was to gather and describe different methods that can be used to assess the bioaccessibility of nutraceuticals and functional foods, along with the most important factors that can impact this process. The link between simulated digestion testing of phytochemicals and their in vitro bioactivity is also discussed, with a special focus on the potential of developing nutraceuticals and functional foods from simple plant materials. The bioactive potential of certain classes of phytochemicals from nutraceuticals and functional foods is susceptible to different variations during the bioaccessibility assessment, with different factors contributing to this variability, namely the chemical composition and the nature of the matrix. Regardless of the high number of studies, the current methodology fails to assume correlations between bioaccessibility and bioactivity, and the findings of this review indicate a necessity for updated and standardized protocols.

Abstract
A coupled in vitro digestion/Caco-2 model was employed to assess iron bioavailability from wheat Aegilops derivatives selected for high iron and protein contents. The iron content in wheat genotypes used in this study correlated to a great extent with both protein (r = 0.80) and phytate (r = 0.68) contents. The iron bioavailability was based on Caco-2 cell ferritin formation from cooked digests of these derivatives (relative to WL711 control) and correlated positively with dialyzable iron (r = 0.63) and total iron content (r = 0.38) but not with the phytate content. The apparently decreased phytate/iron molar ratios, however, correlated negatively (r = -0.42) with the iron bioavailability, justifying the utilization of these parameters in biofortification programs. Iron bioavailability in the derivatives increased up to 1.5-fold, corresponding to a 1.5-2.2-fold increase observed in iron content over control. These data suggest that biofortification for iron proportionately leading to higher iron bioavailability will be the most feasible and cost-effective approach to combat micronutrient deficiency.

Abstract
The in vitro effects of inulin on the fluxes of Fe (F(Fe)) and uptake by Caco-2 cells from FeSO4 and FeEDTA were evaluated. Cell ferritin formation was used as a measure of Fe uptake. Mitochondrial (MTT test) and lysosomal activities were monitored as biomarkers of the changes of cellular metabolism. Changes in mRNA expression of Fe transporters, DMT1 and Dcytb, were evaluated. Inulin decreased dialyzability and F(Fe) from FeSO4 solution, suggesting a mineral binding effect, but increased those from FeEDTA. Cultures exposed to FeEDTA solutions exhibited higher ferritin values and MTT conversion percentages. Regardless of Fe source, cell Fe uptake and mRNA expression of Fe transporters were similar with or without inulin, suggesting that inulin did not impair Fe uptake. These observations might indicate a faster cellular Fe internalization from FeEDTA solutions. From a physiological perspective, the decreased F(Fe) from FeSO4 might be reflected in a decreased Fe uptake.
