Chinese Ascorbic Acid
I have chinese ascorbic acid. It is very difficult to find in my country (even cheap and shitty as this one). He is what they gave me with the 1 kilogram of this powder:
pH 2.42 (2.1-2.6)
Rotation +21.23o (+20.5-+21.5o)
Additives E% <0.2%
Residue at compressing 0.02% (<10%)
Heavy metals <10ppm
Sulphate ash 0.1% (<0.1%)
oxalic acid 0.2%
They said its food grade ascobic cid (C6H06).
Is it ok?
