For this purpose, 400mL of human milk were collected at the Januário Cicco Maternity Hospital. Ten samples of 1 mL of human milk (milk withoutlecithin) were separated, and 2g of lecithin were added into each aliquot. After saponification, the milk was extracted with hexane, and retinol amount was determined by means of High Performance Liquid Chromatography. Statistical analysis was conducted using Student’s t-Test. The average concentrations of retinol in milk samples without and with lecithin were 28.0±5.1μg/100mL and 35.3±5.0μg/100mL,respectively, being the difference statistically significant (p<0.001). The observed findings suggest thatthe addition of lecithin into milk results in high vitamin A provision. Therefore, reporting these data is of great value as for the Milk Banks, as it would guarantee the provision of human milk with highnutritional value, and for other studies that make use of milk as an indicator for monitoring nutritionalstate of lipids or liposoluble vitaminsen-USAttribution 3.0 Brazilhttp://creativecommons.org/licenses/by/3.0/br/LecitinaVitamina ALeite maternoLecithinVitamin AHuman milkarticle
