娇气但不得不用，维生素让营养品、保健品行业多年来面临着一个难题：配方不同、剂型不同，甚至检测方法也不同，在种种环境下，它们如何保持稳定？ 检测标准依据又该如何界定？ 众所周知，维生素种类繁多，它们是维持生命活动必不可少的微量有机物质，但它们的化学结构却异常脆弱。 根据物理性质分类，维生素可分为脂溶性(A、D、E、K)、水溶性( C、B1、B2、B6、B12、泛酸、PP、生物素、叶酸)两类。水溶性维生素（如B1和C）通 常比脂溶性维生素更不稳定。因为它们更容易溶解于加工过程中的水相环境，还会和其他成分发生相互作用，而且水溶性维生素，普遍对热、光、氧气和碱 性环境敏感，尤其在高温（约70℃）下易分解；脂溶性维生素的热稳定性相对好点（可耐120℃左右），但对光、氧气和金属离子又敏感，尤其在油脂酸败 时很容易被破坏。 不稳定的典型代表——维生素B1 在所有维生素中，维生素B1（硫胺素）可以算是不稳定的典型代表，它是由嘧啶环和噻唑环通过亚甲基桥连接组成，其分子结构对多种环境因素敏感。 近年，营养品、保健品行业一直争议不断，虽然现在的消费者对基础营养补充的认知在提升，但依然对产品有效性保持怀疑态度。尤其是"敏感又脆弱又活 ...
