Abstract:RESUMO -Considerando a magnitude da hipovitaminose A como problema de saúde pública no mundo e a disponibilidade de frutos ricos em pró-vitamina A, como a pupunha (Bactris gasipaes Kunth) na região Amazônica, determinou-se a biodisponibilidade de vitamina A da mesma em ratos, utilizando o método preventivo. Os resultados indicaram ser a pupunha uma fonte de vitamina A altamente biodisponível, com eficiência relativa de 250,8% quando comparado com o grupo controle (100%).Palavras-chave: vitamina A; pupunha; bio… Show more
“…In previous reports, Yuyama et al evaluated the bioavailability of carotenoids from other two palm fruits, buriti (Mauritia flexuosa L.) and pupunha (Bactris gasipaes Kunth), using liver retinol accumulation in rats. The authors also found higher β-carotene bioavailability in the groups fed diets supplemented with buriti and pupunha flours in relation to the retinyl palmitate, the respective control group (33,34). These results suggest that these Brazilian palm fruits may be a good source of β-carotene and vitamin A for rats; however, the ability of this model to predict bioavailability in a healthy human population needs to be verified.…”
Carotenoid bioavailability is influenced by various factors including the food matrix. The release of those molecules from the food matrix is the initial and most important step in the absorption process. The relative bioavailability of bocaiuva pulp beta-carotene in relation to pure beta-carotene was assayed by a hepatic retinol store, in vitamin A deficient Wistar rats. After the depletion period, the vitamin A deficient rats were separated into two groups and fed an AIN-93G modified diet, which contained 14 400 microg of pure beta-carotene (beta-carotene diet) or 13 475 microg of beta-carotene from 275 g of bocaiuva pulp (bocaiuva diet) per 1 kg of the diet as a vitamin A source. Both experimental diets resulted in similar body weight gains. The bioavailability, estimated as Retinol Accumulation Factor, was 7.3 and 3.5 for the beta-carotene and the Bocaiuva group, respectively. These results show that in spite of the matrix of the bocaiuva pulp, the beta-carotene bioavailability from this fruit was higher than the pure beta-carotene.

“…Regarding vitamins (fat and water soluble), peach palm fruit is seen as a good source of vitamins A, B, and C, in addition to the mesocarp being rich in α-tocopherol, similar to other species in the Amazon region [ 107 , 114 , 115 ]. Yuyama et al [ 115 ] evaluated the bioavailability of vitamin A from the peach palm using the preventive method in rats.…”
Section: Peach Palm Products: Diversity In Consumption Chemical Compo...mentioning
The extraction and commercialization of palm hearts is the most profitable activity involving the peach palm (Bactris gasipaes), while consumption of its fruits is limited to Amazonian communities. The excessive attention paid to the implementation of germplasm banks contributed to the lack of development of high-performance varieties, limiting the production and consumption of peach palm fruits and by-products. In addition, with the fragmentation of the Amazonian rainforest, wild populations are in danger of extinction. The species domestication, initiated by Native Amazonians, generated a large variety of peach palm populations, as evidenced by the diversity in fruit sizes and quality. Some advances in agronomic traits also took place. However, more research needs to be conducted to understand the implications of climatic changes on plant physiological performance. Indeed, the key point is that the exploitation of the full potential of B. gasipaes has not been completely exploited. Therefore, understanding the state-of-the-art research on the peach palm with a focus on its underutilized resources is essential for expanding plantations and, consequently, promoting the market expansion of the peach palm as a fruit crop.
“…Exclusive olive oil consumption has been reported to be directly linked to lower risk of coronary artery disease [1]. Plants from Amazonian Region have a diversity of fruits like açaí [2], bacaba [3][4][5], buriti [6][7][8], pupunha [3,9,10] that can be used as source of functional oils due to their high contents of phenolic compounds, as well as lipossoluble vitamins and unsaturated fatty acids. Many of these fruits present pulp and seeds rich in oils [1] containing saturated and unsaturated fatty acids with nutritional value that may comparable to ingredients of Mediterranean diet.…”
Native plants from the Brazilian Amazon Biome are rich in nutrientes, oils and fats and, therefore, represent a very important regional food resource. Althoung there is a global interest in the nutritional potential of tropical fruits, the potential of Amazonian fruits as source of essential fatty acids is still under exploited, since their composition is still understudied. 1 H Magnetic Resonance Nuclear ( 1 H NMR) is a robust spectroscopic tool to profile fatty acids components in oils. The objectives of this work were to use 1 H NMR to determine the fatty acids profile and the physicochemical properties of crude oils and fats obtained from fruits of Brazilian Amazon: açaí, ata-brava, bacaba, buriti, buritirana, murici amarelo, murici vermelho, piaçaba braba, tucumanzinho, pupunha red and yellow varieties. Oils were obtained by Soxhlet extraction using hexane as a solvent. After solvent removal by rotoevaporation, the resulting oils and fats were analyzed by 1 H NMR spectroscopy. Unsaturated fatty acids oleic (ω9), linoleic (ω6) and linolenic (ω3) acids were quantified in the oils and their physicochemical properties were determined. It was observed that the oils have predominately ω9 fatty acids, followed by ω6 and ω3 representatives. The physicochemical properties confirmed edibility and good quality of oils and fats present in the aforementioned Amazonian fruits.
