An ethanol-based process to simultaneously extract and fractionate carotenoids from Mauritia flexuosa L. Pulp Rev. Bras. Frutic.
Ribeiro,Bernardo Dias; Nascimento,Rafaella Ferreira; Barreto,Daniel Weingart; Coelho,Maria Alice Zarur; Freitas,Suely Pereira.
Mauritia vinifera (buriti) is a palm tree that grows wild in different areas of Brazil, particularly in the Amazonian region. The buriti oil is rich in carotenoids, especially in β-carotene. The growing interest in other natural sources of β-carotene has stimulated the industrial use of buriti as a raw material for pulp oil extraction. Most processes are based on the conventional technologies, involving drying and pressing the pulp for oil recovery and further separation of carotenoids in a liquid phase using organics solvents. In the present work, the ethanol-based process was evaluated for simultaneous carotenoids recovering and fractionating from buriti pulp. The raw material and ethanol, 1:4 ratio, were placed in an erlenmeyer flask and maintained at...

Composição nutricional do fruto de licuri (Syagrus coronata (Martius) Beccari) Rev. Bras. Bot.
CREPALDI,IARA CÂNDIDO; ALMEIDA-MURADIAN,LIGIA BICUDO DE; RIOS,MAGDA DIAS GONÇALVES; PENTEADO,MARILENE DE VUONO CAMARGO; SALATINO,ANTONIO.
A palmeira Syagrus coronata, licuri, nativa do sertão baiano, é importante fonte de alimento para pessoas e animais. Sua amêndoa é usada como substituta do milho para a alimentação das aves. A composição nutricional indicou que o fruto é altamente calórico. Os principais constituintes das amêndoas são lipídeos e proteínas. Na polpa, o beta-caroteno é um importante constituinte. Discute-se a utilização dos frutos como complemento vitamínico de escolares da área rural da caatinga baiana.

Effect of extrusion-cooking in total carotenoids content in cream and orange flesh sweet potato cultivars Horticultura Brasileira
Fonseca,Marcos José de O; Soares,Antonio G; Freire Junior,Murillo; Almeida,Dejair L de; Ascheri,José Luiz R.
Sweet potato (Ipomoea batatas) is a food crop that supplies energy, minerals and vitamins C and B. Some cultivars are very rich in carotenoids (pro-vitamin A). In this study were evaluated and compared the total carotenoids content of two cultivars and the losses on the dehydrated extruded sweet potato flour. Samples from organic and conventional crops were analyzed, in the form of fresh and dehydrated extruded samples. Total carotenoids content of the fresh product, expressed on wet basis, was of 437 µg 100 g-1 for the cream cultivar and 10,12 µg 100 g-1 for the orange cultivar. After dehydration, losses of total carotenoids were of 41% and 38%, respectively. The fresh orange cultivar presented high total carotenoids content in comparison to the cream...

Elaboração de óleo de soja enriquecido com carotenoides provitamínicos A para aplicação em snacks. Infoteca-e
PACHECO, S.; BORGUINI, R. G.; CARVALHO, C. W. P. de; SÁ, D. de G. C. F. de; NOGUEIRA, R. I.; SANTIAGO, M. C. P. de A.; JESUS, M. S. C. de; GODOY, R. L. de O..
Os carotenoides são pigmentos naturais responsáveis pela cor amarela, laranja ou vermelha de muitos alimentos. Alguns são precursores de vitamina A e podem ser utilizados no combate à deficiência desta vitamina. A presença de lipídeos na dieta é fundamental para a absorção dos carotenoides. Neste trabalho foi descrito o processamento para a elaboração de óleo de soja enriquecido com carotenoides provitamínicos A para aplicação em snacks de milho obtidos por extrusão, visando contribuir para o atendimento à Ingestão Diária Recomendada para vitamina A. O óleo de soja comercial e o enriquecido com carotenoides provitamínicos A foram aplicados aos snacks. O teor de carotenoides totais nos snacks elaborados com óleo enriquecido e com óleo comercial foi de 2.294...

Background: Introgression of transgenes from crops to their wild species may enhance the adaptive advantage and therefore the invasiveness of and weedy forms. The study evaluated the effect of Africa Biofortified Sorghum (ABS) genes from ABS event 188 on the vegetative and reproductive features of the F2 populations derived from crosses with Sorghum bicolor subsp. drummondii. Results: F1 populations were obtained from reciprocal crosses involving ABS event 188 and its null segregant with inbred weedy parents from S. bicolor subsp. drummondii. Four F2 populations and four parental populations were raised in RCBD with 4 replications in a confined field plot for two seasons. Vegetative and reproductive traits were evaluated. The vigour shown in the F2...
