We investigated the effect of the composition of the storage container, Holder pasteurisation, and conditions during tube feeding on the concentration of selected vitamins in human milk. Though the fat soluble vitamins A, D, and E were not affected, the concentration of several water soluble vitamins decreased. The lower vitamin C concentration of milk stored in polypropylene containers compared with milk stored in glass containers (29%) was not significant. Holder pasteurisation significantly lowered the concentrations of vitamins C (36%), folacin (31%), and B6 (15%). Tube feeding significantly lowered the concentrations of vitamins C (44%) and B6 (19%), and exposure to phototherapy seemed to lower the vitamin C concentration (53%) further. Low birthweight infants have increased vitamin requirements. Vitamin losses in expressed human milk before or during feeding may increase the incidence of vitamin deficiencies in these babies.
我们研究了储存容器的成分、霍尔德巴氏灭菌法以及管饲期间的条件对人乳中特定维生素浓度的影响。尽管脂溶性维生素A、D和E未受影响，但几种水溶性维生素的浓度有所下降。与储存在玻璃容器中的母乳相比，储存在聚丙烯容器中的母乳维生素C浓度较低（29%），但差异不显著。霍尔德巴氏灭菌法显著降低了维生素C（36%）、叶酰素（31%）和维生素B6（15%）的浓度。管饲显著降低了维生素C（44%）和维生素B6（19%）的浓度，而接受光疗似乎进一步降低了维生素C浓度（53%）。低体重婴儿的维生素需求量增加。挤出来的母乳在喂养前或喂养期间的维生素损失可能会增加这些婴儿维生素缺乏症的发生率。
