目的：研究婴幼儿配方粉中影响维生素B2稳定性的因素。方法本实验通过紫外可见光分光光度法,研究了光照、温度、pH、金属离子、氧化剂、抗氧化剂、防腐剂和糖类对维生素B2稳定性的影响。结果光照对维生素B2的影响最大,1 h损失率达到40%；金属离子中Mg2+5 h后会对B2造成约10%的损失；Fe3+和Cu2+可与维生素B2反应生成其他物质使B2造成破坏；维生素C在5 h后对维生素B2造成约13.8%的损失；常见的食品添加剂山梨酸钾和苯甲酸钠、以及氧化剂双氧水对维生素B2的影响有限；葡萄糖不能造成维生素B2的损失,蔗糖可以造成20%的损失。结论维生素B2的稳定性受多种因素的影响,其中影响最大的是光照,某些金属离子、维生素C和蔗糖也会影响维生素B2的稳定性。

Objective To study the impact factors of vitamin B2 stability in infant formula powder. Methods Illumination, temperature, pH, metal ions, oxidants, antioxidants, preservatives and sugar were studied on the stability of vitamin B2 by UV visible spectrophotometry. Results Effect of light on vitamin B2 was the biggest, with its 1-h loss rate of 40%;Mg2+could cause vitamin B2 loss rate to 10%after 5 h, Fe3+and Cu2+could cause damage through react with vitamin B2 and generate other substances;Vitamin C could cause about 13.8% loss of vitamin B2; Common food additives, such as potassium sorbate, sodium benzoate, and oxidant hydrogen peroxide had the limited effect on vitamin B2;Glucose could not cause the loss of vitamin B2, and sugar could cause the loss of 20%. Conclusion The stability of vitamin B2 is affected by many factors, among which the greatest impact is the light;some metal ions, vitamin C and sucrose also affect the stability of vitamin B2.
