Factors were studied influencing the stability of ascorbic acid (AA) in carbonated drink "Legenda". It has been established that beet-tea pigment and its mixture with polyvinylpyrrolidone produce a high stabilizing effect on AA due to formation of stable complexes with AA, which was supported by the data of spectrophotometry.
研究了影响碳酸饮料“传奇”中抗坏血酸（AA）稳定性的因素。已确定甜菜茶色素及其与聚乙烯吡咯烷酮的混合物对AA具有高稳定作用，这是由于它们与AA形成了稳定的络合物，分光光度法的数据支持了这一点。
