Roles Classification
Chemical Role(s): protic solvent
A polar solvent that is capable of acting as a hydron (proton) donor.
Bronsted acid
A molecular entity capable of donating a hydron to an acceptor (Bronsted base).
(via oxoacid )
Biological Role(s): food acidity regulator
A food additive that is used to change or otherwise control the acidity or alkalinity of foods. They may be acids, bases, neutralising agents or buffering agents.
Daphnia magna metabolite
A Daphnia metabolite produced by the species Daphnia magna.
antimicrobial food preservative
A food preservative which prevents decomposition of food by preventing the growth of fungi or bacteria. In European countries, E-numbers for permitted food preservatives are from E200 to E299, divided into sorbates (E200-209), benzoates (E210-219), sulfites (E220-229), phenols and formates (E230-239), nitrates (E240-259), acetates (E260-269), lactates (E270-279), propionates (E280-289) and others (E290-299).
