Joalokaha ho fanoe ka kakaretso, asiti ea acetic ke tharollo ea metsi a 6 N (hoo e ka bang 36%) kapa tharollo ea 1 N (hoo e ka bang 6%). Lintho tsena kapa tse ling tse hlapollang li sebelisoa bakeng sa ho eketsa tekanyo e loketseng ea asiti ea acetic lijong. Acetic acid ke tšobotsi ea asiti ea asene, mahloriso a eona a tloha ho 3.5 ho isa ho 5.6%. Acetic acid le acetates li teng limela tse ngata le lisele tsa liphoofolo ka tekanyo e nyenyane empa e lemohuoa. Ke li-metabolism tse tloaelehileng, li hlahisoa ke mefuta ea baktheria e kang Acetobacter 'me e ka etsoa ka ho feletseng ho tloha carbon dioxide ka likokoana-hloko tse kang Clostridium thermoaceticum.
