O le ā le Sodium Dehydroacetate CAS 4418-26-2?

O le sodium dehydroacetate o se pauta paʻepaʻe e pei o se tioata e faigofie ona solo i le vai. E vaivai lona acidity i le vai ma e mafai ona faʻasaʻoloto le kesi SO2 i lalo o tulaga acidic. O le sodium dehydroacetate o se mea e puipuia ai meaʻai e lautele lona aʻafiaga ma e matuā teteʻe atu i siama, ma e matuā malosi lona malosi e teteʻe atu ai i le popole ma le fefete. I le fua lava e tasi, o le aʻafiaga o le teteʻe atu i siama e tele taimi pe sefulu taimi foʻi e sili atu nai lo le sodium benzoate ma le potassium sorbate e masani ona faʻaaogaina. O le mea e sili ona tāua, o lona laʻititi o lona aʻafiaga e teteʻe atu ai i siama e gaosia ai le acid, aemaise lava siama lactic acid.

Talosaga

1. O le sodium dehydroacetate o se vailaʻau e teteʻe atu i siama ma le saogalemu maualuga, lautele le vaega e teteʻe atu ai i siama, ma malosi le malosi e teteʻe atu ai i siama. E itiiti sona aʻafiaga i le acidity poʻo le alkalinity o meaʻai ma e mafai ona faatumauina le maualuga o lona aoga e teteʻe atu ai i siama i lalo o tulaga acidic poʻo sina alkaline. O lona malosi e teteʻe atu ai i siama e sili atu nai lo le sodium benzoate, potassium sorbate, calcium propionate, ma isi, ma avea ai ma se mea e faʻasaoina ai meaʻai lelei.
2. E mafai ona fa'aaogaina le sodium dehydroacetate mo le togafitia o luga o u'amea, fa'amamāina o le kelu, ma le puipuia o le ele i luga o luga o u'amea.
3. E mafai fo'i ona fa'aaogaina le sodium dehydroacetate mo su'esu'ega fa'akemikolo ma le sauniaina o mordants.
4. O le sodium dehydroacetate e faʻaaogaina foʻi i le gaosiga o pepa, paʻu, ufiufi, mea teuteu, ma isi mea faapena
