Samples were collected weekly and maintained frozen until pasteurization. Analyses of retinol and β-carotene in human milk were undertaken before and after the treatment (pasteurization), chromatographic method. Aliquots of approximately 5 mL of milk were taken from each sample. The babies included in the study were weight > 2500g. The Vitamin A concentration in the milk, before and after the processing, was found to be insufficient for that required (46.57 ± 6.28 µg/dL and 31.55 ± 8.29 µg/dL respectively) for children who feed exclusively on HMB milk, notably premature babies, whose Vitamin A requirements are greater and whose capacity for ingesting milk is lower than that of fully born babies. The loss of Vitamin A through processing was, in this study, 32.51%. To guarantee hepatic reserves and protect against deficiencies, it would be necessary that the vitamin A concentration in the milk be higher than 80 µg/dL. Esse estudo teve como objetivo determinar os teores de vitamina A no Leite Humano Materno (LHM), de 50 mães doadoras do Banco de Leite Humano (BLH), da Maternidade Ana Braga, em Manaus-AM. As amostras foram coletadas semanalmente e mantidas congeladas até a pasteurização. As análises de retinol e β-caroteno no leite humano foram realizadas antes e após o tratamento (pasteurização), mediante o método cromatográfico. Foram retiradas alíquotas de 5 mL aproximadamente de leite de cada amostra. Os pesos dos bebês ao nascer das mães doadoras de leite incluídos no estudo foram > 2500g. A concentração de vitamina A no leite tanto antes quanto após o processamento, não foram suficientes para suprir o requerimento (46,75 ± 6,28 μg/dL e 31,55 ± 8,29 μg/dL, respectivamente), de crianças que se alimentam exclusivamente do leite do BLH, notadamente as pré-termo, cujos requerimentos de vitamina A são maiores e a capacidade de ingerir leite é menor do que os nascidos a termo. A perda de vitamina A pelo processamento, em nosso estudo foi de 32,51%. Para garantir a formação de reservas hepáticas e a proteção contra deficiência de vitamina A, seriam necessárias concentrações dessa vitamina no leite superiores a 80 μg/dL. 2020-04-24T15:34:33Z 2020-04-24T15:34:33Z 2010 Artigo https://repositorio.inpa.gov.br/handle/1/13626 10.1590/S0044-59672010000100008 pt_BR Volume 40, Número 1, Pags. 59-64 Attribution-NonCommercial-NoDerivs 3.0 Brazil http://creativecommons.org/licenses/by-nc-nd/3.0/br/ application/pdf Acta Amazonica
