    my name is jack from Hangzhou, China. I'm a chemical teacher and know some details of food additives, such as preservatives, sweeteners, acidulents, thickeners and so on.

    I would like to answer some questions if somebody ask such questions in the forum.

    Welcome to the PF, Jack. :smile:

    We have a chemistry forum where your help is certainly appreciated. Also, we have a Homework Help, Chemistry forum where you can help students with their schoolwork questions. The schoolwork forums have different rules, though, so please be sure to read through the Homework Help rules (see INFO at the top of the page). Mainly, we can't do the students' work for them, but we can provide hints and find mistakes in their work.
