The sugar cane juice for making sugar they mix urea then they separate the sugar , which later the make the juice in solid form . So how can we remove the chemical (un wanted)from sugar before eating ?
You don't think the sugar refiners address this when they put the product onto market? They probably crystallize out pure sucrose...
The sugar that we buy in packets is EXTREMELY pure. And not only it is chemically PURE, it is highly OPTICALLY pure in addition. And it still won't do your teeth any good.
If you are ever in a country where they grow sugar commercially, it it is very nice to chew on a stick of sugar cane. The rum that they make from the sugar cane juice will ensure a horrible night.
