This is such an important topic! Congratulations to the new ones! Do you protect the substitutes for the tsukr, which are more often than not the worst tsukor. If this is so, then how and what minimal quantity can you identify? Do you know that the distributors may not indicate on the packaging if the share is very small - which you identify and inform the supplier?
You touch on an important topic, but you're focused on sugar, which is important, but I don't think the list is complete.
You should think not only about sugar and identify it, but it is also important to say that the product contains maltadextrin or starch. Not the starch that is in potatoes, but the one obtained by processing - it is more dangerous than sugar.
