摘要

Bee pollen from aroeira (Astronium urundeuva) is rich in nutrients and possesses medicinal properties. This tree species is native to the semi-arid regions of Brazil and shows notable potential for beekeeping. This study aimed to characterize the structure and chemical composition of aroeira bee pollen, considering the effects of seasonality and storage. Samples were collected in the central region of Brazil in May/June over two consecutive years and stored at -21ºC for up to 240 days. Structural and biochemical analyses showed that the May/June samples were monofloral (> 70% aroeira pollen), exhibiting a brown color and 37.5% higher protein content compared to samples without aroeira pollen. The sample with over 84% aroeira pollen grains exhibited markedly higher levels of phenolic compounds (57.5%), yellow flavonoids (20%), and carotenoids (1000%) compared to the sample lacking aroeira pollen. Dehydration after storage led to a significant decrease in these bioactive compounds, with reductions of 32% in carotenoids, 500% in total phenolics, and 250% in yellow flavonoids; however, antioxidant activity did not change. Phenolic acids identified include salicylic, vanillic, syringic, gallic, ferulic, and caffeic. Aroeira bee pollen can be considered a functional food and superfood with high nutritional value. However, dehydration and long-term storage reduce its nutritional quality.
