Is there any confirmatory method to identify acid washed ginger?
If there are no information about confirmatory test of acid washed ginger , but you know the acid used in the acid treatment which is H2SO4 ; then comparative analysis of the sulfate content between the unwashed ginger and the washed one will give you positive values of confirmation…FYI washed gingee had a shiny surface to the unwashed one…
@zubi_ias just out of curiosity, would you mind explaining the relevance of this…or why this is specifically important in your case, thanks
Thank you.
There are news that some trader are involved to this malpractice…
hi @zubi_ias , ok…noted…may be because it is sulphuric acid - a mineral acid, can be washed off, and less impact considered to other agents like pesticides etc…
Now a days people are more careful and we have the tendency to soak veggies, hardy fruits in water for sometime before it is consumed. Even veggies washes, or cider vinegars , salt are also used to soak these items before consumption at home.
Is this acid wash causing some issues while it is being used industrially for food processes. thanks
Its a way of making those ginger rejects look acceptable as the surface become smoother and blemishes can be masked.Incidentally the acid is absorbed in the ginger which can be a food hazard knowing the irritant and (possibly toxic effect to the digestive system.)in consuming such acid treated ginger.Thats actually a form of " adulteration "…
