ABSTRACT
This study represents a pioneering investigation and comparative analysis of lipid extracts from four different colors of peach palm (Bactris gasipaes Kunt) fruits-red, yellow, green, and white-by employing a green method based on ethanolic ultrasound-assisted extraction. This study examined the extraction yield, physico-chemical-quality attributes, chromatographic profiles (GC), color measurements, total carotenoid content, differential thermogravimetry (TG/DTA), and infrared spectroscopy (FTIR). The obtained lipid extracts displayed a high quality, considering the physico-chemical parameters of the Codex Alimentarius, and a fatty acids profile characterized by unsaturated fatty acids, notably omegas (ω-3, ω-6, and ω-9). The indices of atherogenicity (A.I.), thrombogenicity (I.T.), and hypocholesterolemic and hypercholesterolemic ratios revealed superior outcomes for the red peach palm lipid extract (approximately 0.35, 0.52, and 2.75, respectively), along with higher levels of ß-carotene (748.36 µg of ß-carotene per 100 g-1 of lipid extract) compared to the yellow, green, and white counterparts. Consequently, this research successfully demonstrates the efficacy of using a green extraction method in preserving the lipid's quality, which can display cardiovascular functionality and thermal stability. These findings underscore the considerable potential of peach palm lipid extract as a valuable raw material for diverse industrial applications across various sectors. The results support its utilization in the production of functional food products and nutraceuticals due to its favorable fatty acid composition, potent antioxidant properties exhibited by its high ß-carotene content, and notable cardiovascular functionality indices.
ABSTRACT
El objetivo del estudio fue evaluar la aceptación de 4 formulaciones de un bocadillo de pejibaye combinado con harina de maíz, por consumidores; así como determinar su potencial como alimento funcional. Se evaluó el agrado a las 4 formulaciones, en 100 consumidores de bocadillos y los resultados fueron sometidos a un análisis de conglomerados. Los resultados se conformaron en dos conglomerados, en donde el 2 fue el que otorgó mejores calificaciones a las características evaluadas. En dicho conglomerado, quedaron la mayoría de las personas que consumen más frecuentemente bocadillos y pejibaye. Todos los consumidores del conglomerado 2 y aproximadamente el 85% del grupo 1 indicaron que comprarían el producto, por lo que se concluyó que hay un nicho de mercado para el bocadillo de pejibaye. Posteriormente, se realizó una evaluación cualitativa con los dos productos de mayor aceptación según el estudio cuantitativo. Se realizaron 2 sesiones con participantes de clase media-media: una con profesionales y otra con amas de casa. Se determinó que la combinación de goma tara y carboximetilcelulosa (CMC) permite obtener un efecto sinérgico positivo para las características sensoriales de los bocadillos de pejibaye: la goma resalta el sabor natural a pejibaye y la CMC mejora la crujencia. El bocadillo contiene en 100 g de producto en base seca: 9 ± 4 g de grasa, 14,0 ± 0,3 g de fibra dietética, 15500 ± 32 μg de carotenoides y tiene una capacidad antioxidante de 4700 ± 8 μmol TE, lo que evidencia su potencial como alimento funcional.
The aim of this study was to evaluate consumers acceptance of a peach palm snack and to determine its potential as a functional food by chemical characterization. An assessment was conducted with 100 consumers to determine the acceptance of different snack formulations and the results were subjected to cluster analysis. This analysis revealed two groups. Group 2 included people that consume snacks and peach palm frequently and showed the highest grades for the snack evaluated characteristics. All the consumers in group 2 and approximately 85% of the consumers in group 1 indicated that they would buy the product suggesting that there is a niche market for the developed peach palm snack. Also, a qualitative evaluation, using mini focus groups, of the two most widely accepted formulas of the snack (chosen according to previously described study) was performed. The sessions considered the opinion of middle class professionals and housewives. It was determined that the combination of tara gum and carboxymethylcellulose (CMC) allows a positive synergistic effect on the sensory characteristics of the snack, highlighting natural peach flavor and improving crunchiness. In a dry basis, the snack contains per 100 g: 9 ± 4 g of fat, 14.0 ± 0.3 g of dietary fiber, 15500 ± 32 μg of carotenoids and has an antioxidant capacity of 4700 ± 8 μmol TE, which demonstrates its potential as a functional food.

Undertaken in the context of the magnitude of the public health problem of vitamin A deficiency in the world, and the availability of pro-vitamin A rich fruits in Amazonia, this study evaluated the bioavailability of Vitamin A from peach palm (Bactris gasipaes Kunth) in rats using the preventive method. The results of the study indicate that peach palm is a highly bioavailability source of Vitamin A, with a relative efficiency of 250.8% when compared with the respective control groups (100%).
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%).
