Abstract
The objective of the present study was to evaluate the effect of lecithin addition on retinol concentration, and its consequent availability in processed human milk. For this purpose, 400mL of human milk were collected at the Januário Cicco Maternity Hospital. Ten samples of 1 mL of human milk (milk without lecithin) 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 that the 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 high nutritional value, and for other studies that make use of milk as an indicator for monitoring nutritional state of lipids or liposoluble vitamins.References
