Els Patriarques hem fet un estudi d’una reacci\u00f3 qu\u00edmica. Hem comprovat que, per exemple,\u00a0 quan deixem una poma tallada sobre la taula o un alvocat obert durant una estona es tornen marrons. Aix\u00f2 passa per un proc\u00e9s anomenat oxidaci\u00f3. L\u2019oxidaci\u00f3 es produeix quan certes subst\u00e0ncies dels aliments entren en contacte amb l\u2019oxigen de l\u2019aire. Aquest proc\u00e9s altera el color, el sabor i fins i tot el valor nutricional dels aliments. Hem pogut experimentar que hi ha diferents maneres de retardar aquest proc\u00e9s.<\/p>\n

Si cliqueu a\u00a0AQU\u00cd<\/a> podreu veure alguna foto m\u00e9s d’aquesta pr\u00e0ctica.<\/p>\n","protected":false},"excerpt":{"rendered":"
