Les amines bi\u00f2genes, una d\u2019elles la histamina<\/a>, es formen en els aliments per acci\u00f3 dels enzims descarboxilasa dels microorganismes a partir dels amino\u00e0cids precursors. Fet que no passa en les amines naturals o fisiol\u00f2giques, que es formen durant processos metab\u00f2lics de plantes i animals.<\/p>\n

De tota manera, la capacitat i la intensitat de formaci\u00f3 d\u2019una o m\u00e9s d\u2019una amina bi\u00f2gena varia segons la soca considerada i, a m\u00e9s, es veu afectada per les condicions en qu\u00e8 aquesta es desenvolupa. La possibilitat de rutes biosint\u00e8tiques alternatives i la participaci\u00f3 combinada de diferents tipus de microorganismes i les seves possibles interaccions complica encara m\u00e9s l\u2019establiment prec\u00eds de la responsabilitat de la biog\u00e8nesi d\u2019aquestes amines en els aliments.<\/span><\/span><\/div>\n

\n<\/span><\/span>Per tant, es necessiten uns requeriments concrets per tal que pugui cr\u00e9ixer histamina en els aliments:<\/span><\/span><\/div>\n
1. Que hi hagi un creixement de microorganismes amb activitat descarboxilasa.<\/span><\/span><\/div>\n
2. Que hi hagi disponibilitat d\u2019amino\u00e0cids precursors i cofactors.<\/span><\/span><\/div>\n

3. Que les condicions ambientals siguin favorables per la s\u00edntesi i l\u2019activitat de les descarboxilases (pH, Aw, T\u00aa\u2026).<\/span><\/p>\n
