The absorption of some carotenoids has been reported to be decreased by coingestion of relatively high concentrations of other carotenoids. It is unclear if such interactions occur among carotenoids during the digestion of plant foods. Current varieties of maize contain limited amounts of the pro-vitamin A (pro-VA) carotenoids beta-carotene (BC) and beta-cryptoxanthin (BCX) and relatively higher levels of their oxygenated metabolites lutein (LUT) and zeaxanthin (ZEA). Here, we examined if LUT… 

Figures and Tables from this paper

β-Carotene bioaccessibility from biofortified maize (Zea mays) is related to its density and is negatively influenced by lutein and zeaxanthin.

The results together suggest that the enrichment of pro-VA carotenoids together with decreasing the oxygenatedCarotenoid metabolites such as LUT and ZEA will further improve the bioavailability of BC from maize hybrids.

Carotenoid Content and Bioaccessibility in Commercial Maize Hybrids

The objective of the present study was to determine the content and bioaccessibility of carotenoids in 104 maize hybrids available at the market. Lutein, zeaxanthin, α- and β-cryptoxanthin, and

Effect of processing and oil type on carotene bioaccessibility in traditional foods prepared with flour and puree from orange-fleshed sweetpotatoes

Summary Consumption of Orange-Fleshed sweetpotato (OFSP) and products as source of provitamin A is being pro-moted to tackle vitamin A deficiency (VAD) in sub-Saharan Africa. However, limited

Effect of Style of Home Cooking on Retention and Bioaccessibility of Pro‐vitamin A Carotenoids in Biofortified Pumpkin (Cucurbita moschata Duch.) Genotypes

The effect of three common styles of home cooking of pumpkin on retention and the bioaccessibility of pro-vitamin A carotenoids in five genotypes of biofortified pumpkin developed by Embrapa is investigated.

Bioaccessibility of provitamin A carotenoids from fruits: application of a standardised static in vitro digestion method.

The aim of this study was to adopt the in vitro digestion model suitable for food, proposed in a consensus paper by Minekus et al. (2014), to assess the bioaccessibility of carotenoids from the fruits that are the major contributors to the intake of β-cryptoxanthin in Spain and loquat and to propose the application of the previously mentioned standardized in vitro protocol.

β-Cryptoxanthin- and α-carotene-rich foods have greater apparent bioavailability than β-carotene-rich foods in Western diets

Estimating the apparent bioavailability of the major sources of provitamin A (AC, BC and CX) from the diet by comparing the concentrations of these carotenoids in blood to their dietary intakes suggests that CX-rich foods might be better sources of vitamin A than expected.

Effect of processing and oil type on carotene bioaccessibility in traditional foods prepared with flour and puree from orange‐fleshed sweetpotatoes

Consumption of Orange‐Fleshed sweetpotato (OFSP) and products as source of provitamin A is being promoted to tackle vitamin A deficiency (VAD) in sub‐Saharan Africa. However, limited information is

Effects of three cooking methods on content changes and absorption efficiencies of carotenoids in maize.

Tortilla and porridge are better dietary choices for the intake of xanthophylls and β-carotene, respectively, among maize-based foods, using the in vitro digestion model.

Food Matrix Effects on Bioaccessibility of β-Carotene Can be Measured in an in Vitro Gastrointestinal Model

The food matrix effects on bioaccessibility of β-carotene could be measured using an in vitro model and were consistent with in vivo data.

Digestive stability of xanthophylls exceeds that of carotenes as studied in a dynamic in vitro gastrointestinal system.

The digestive stability of the red-pigmented lycopene and other carotenoids brought in nutritional quantity within different food matrixes is assessed using the TNO gastrointestinal tract model (TIM), which accurately reproduces the main parameters of gastric and small intestinal digestion in human.



Beta-carotene micellarization during in vitro digestion and uptake by Caco-2 cells is directly proportional to beta-carotene content in different genotypes of cassava.

All-trans betaC content appears to provide the key selection marker for breeding cassava to improve VA status and that the more complicated screening procedure using in vitro digestion coupled to cell uptake does not provide additional information on potential bioavailability.

The xanthophyll composition of biofortified maize (Zea mays Sp.) does not influence the bioefficacy of provitamin a carotenoids in Mongolian gerbils (Meriones unguiculatus).

Twice the molar amount of beta-cryptoxanthin was as efficacious as beta-carotene and the proportion of Beta-cryptxanthin or xanthophylls did not appreciably change the VA value of biofortified maize.

Hydrolysis of zeaxanthin esters by carboxyl ester lipase during digestion facilitates micellarization and uptake of the xanthophyll by Caco-2 human intestinal cells.

Dietary Zea esters are hydrolyzed by CEL during the small intestinal phase of digestion and that this conversion enhances Zea bioavailability, suggesting that these carotenoids protect these tissues against photooxidative damage.

Vegetable-borne lutein, lycopene, and beta-carotene compete for incorporation into chylomicrons, with no adverse effect on the medium-term (3-wk) plasma status of carotenoids in humans.

Consumption of carotenoids from different vegetable sources does not diminish plasma carOTenoid concentrations in the medium term, despite the finding in postprandial testing of competitive inhibitory interactions among different carotanoids.

Beta-cryptoxanthin from citrus juices: assessment of bioaccessibility using an in vitro digestion/Caco-2 cell culture model.

Bioaccessibility was investigated by measuring the transfer of carotenoids from different citrus juices into micelles using an in vitro digestion system and preferential uptake by Caco-2 cells of beta-carotene and free beta-CX compared with the two esterified forms showed.

Evaluation of analytical methods for carotenoid extraction from biofortified maize (Zea mays sp.).

The objective was to evaluate carotenoid extraction methods and determine essential steps for use in countries growing biofortified maize and the most reproducible method was a modification of Kurilich and Juvik (1999).

Bioaccessibility of carotenoids and vitamin E from their main dietary sources.

The in vitro model used to measure alpha- and gamma-tocopherol, beta-carotene, lycopene, and lutein bio accessibility from their main dietary sources was well correlated with human-derived bioaccessibility values and relative mean bioavailability values reported in healthy human groups.

Assessment of lutein bioavailability from meals and a supplement using simulated digestion and caco-2 human intestinal cells.

Data support the use of simulated digestion and the Caco-2 cell model as effective tools for identifying factors affecting absorption of dietary carotenoids.

Digestive Stability, micellarization, and uptake of beta-carotene isomers by Caco-2 human intestinal cells.

It is suggested that cis isomers of BC are preferentially micellarized during digestion and transferred across the brush-border surface of the enterocyte from mixed micelles with similar efficiency as all-trans-BC at the concentrations of the carotenoids utilized in this study.
