VC 有很多种化学存在形式,并非只有非结合态的酸一种形态。事实上水溶性的酸和盐在溶液里是一样的,呈现的是酸根离子

  1. E300 ascorbic acid (approved for use as a food additive in the EU,[109] U.S.[110] and Australia and New Zealand)[111]
  2. E301 sodium ascorbate (approved for use as a food additive in the EU,[109] U.S.[112] and Australia and New Zealand)[111]
  3. E302 calcium ascorbate (approved for use as a food additive in the EU,[109] U.S.[110] and Australia and New Zealand)[111]
  4. E303 potassium ascorbate (approved in Australia and New Zealand,[111] but not in U.S.)
  5. E304 fatty acid esters of ascorbic acid such as ascorbyl palmitate (approved for use as a food additive in the EU,[109] U.S.[110] and Australia and New Zealand)[111]

The stereoisomers of Vitamin C have a similar effect in food despite their lack of efficacy in humans. They include erythorbic acid and its sodium salt (E315, E316).[109]

把几种不同结构化学物品都称为vc本身就不科学。像维生素3有几种,只有一种是有效的其它几种都无效果一个道理。懂不懂这道理? -02199- 给 02199 发送悄悄话 (0 bytes) () 10/17/2022 postreply 20:15:48

就像补钙,不是说要补金属态的钙,那会死人的,只要有钙离子就可以了,钙剂起作用的是钙离子 -register0001- 给 register0001 发送悄悄话 (0 bytes) () 10/17/2022 postreply 20:27:19
