The effect of enteral feeding bag composition and freezing and thawing upon the stability of riboflavin and vitamins A and E in an enteral feeding solution was tested. Feeding bags composed of either polyvinyl chloride or polyethylene were filled with an enteral feeding solution. The samples were frozen for 3 months, thawed in warm water, and allowed to stand in room temperature for 12 hr. Samples for vitamin analysis were obtained prior to freezing, upon thawing, and at 12 hr after thawing. No significant differences in vitamin stability due to bag composition or time were seen. These results support the viability of the concept of mixing large batches of enteral feeding solution, and freezing aliquots in individual feeding bags for later use.
测试了肠内营养袋的组成以及冻融对肠内营养溶液中核黄素、维生素A和维生素E稳定性的影响。将由聚氯乙烯或聚乙烯制成的营养袋装满肠内营养溶液。将样品冷冻3个月，在温水中解冻，并在室温下放置12小时。在冷冻前、解冻时以及解冻后12小时获取用于维生素分析的样品。未观察到因袋子组成或时间导致的维生素稳定性有显著差异。这些结果支持了将大批量肠内营养溶液混合，并将等分试样冷冻在单个营养袋中以供日后使用这一概念的可行性。
