dc.description.abstract | The ultrastructure and carotenoid-bearing structures of mamey sapote (Pouteria sapota) chromoplasts were
elucidated using light and transmission electron microscopy and compared to carotenoid deposition forms in red bell pepper
(Capsicum annuum) and sockeye salmon (Oncorhynchus nerka). Globular−tubular chromoplasts of sapote contained numerous
lipid globules and tubules embodying unique provitamin A keto-carotenoids in a lipid-dissolved and presumably liquid-crystalline
form, respectively. Bioaccessibility of sapotexanthin and cryptocapsin was compared to that of structurally related ketocarotenoids
from red bell pepper and salmon. Capsanthin from bell pepper was the most bioaccessible pigment, followed by
sapotexanthin and cryptocapsin esters from mamey sapote. In contrast, astaxanthin from salmon was the least bioaccessible ketocarotenoid.
Thermal treatment and fat addition consistently enhanced bioaccessibility, except for astaxanthin from naturally lipidrich
salmon, which remained unaffected. Although the provitamin A keto-carotenoids from sapote were highly bioaccessible, their
qualitative and quantitative in vivo bioavailability and their conversion to vitamin A remains to be confirmed. | es_ES |
