Aufgrund der verschiedenen Arten von Antioxidantien ist der Wirkungsmechanismus von Antioxidantien nicht derselbe, zusammenfassend l\u00e4sst sich sagen, dass es haupts\u00e4chlich die folgenden sind:
\n1. die Verringerung des Sauerstoffgehalts in Lebensmitteln durch die reduzierende Wirkung von Antioxidantien;
\n2. die Kettenreaktion im Oxidationsprozess zu unterbrechen und zu verhindern, dass der Oxidationsprozess weiter fortschreitet;
\n3. die Aktivit\u00e4t der oxidativen Enzyme zu zerst\u00f6ren und zu schw\u00e4chen, so dass sie die Oxidationsreaktion nicht katalysieren k\u00f6nnen;
\n4. in der Lage sein, die Oxidationsreaktion des geschlossenen Materials zu katalysieren und zu bewirken, wie die Komplexierung die Oxidationsreaktion von Metallionen katalysieren kann. Es folgt eine kurze Einf\u00fchrung in den Mechanismus der Antioxidantien mit den Beispielen der automatischen oxidativen Ranzigkeit von Fetten und \u00d6len und der enzymatischen oxidativen Br\u00e4unung von Lebensmitteln.
\nHemmung der \u00d6l- und Fettoxidation durch Antioxidantien
\nWenn nat\u00fcrliche \u00d6le und Fette der Luft ausgesetzt werden, kommt es zu spontanen Oxidationsreaktionen, bei denen minderwertige Fetts\u00e4uren, Aldehyde, Ketone usw. entstehen, was zu einem schlechten sauren Geruch und einer Verschlechterung des Geschmacks f\u00fchrt, die die Hauptgr\u00fcnde f\u00fcr den Verderb von \u00d6len und Fetten und \u00f6lhaltigen Lebensmitteln sind. Die Autooxidation von Fetten und \u00d6len erfolgt nach dem Reaktionsmechanismus der freien Radikale (auch als freie Radikale bezeichnet). Zun\u00e4chst werden die Fettmolek\u00fcle (ausgedr\u00fcckt als RH) durch W\u00e4rme, Licht oder Metallionen und andere Radikalinitiatoren aktiviert und dann in instabile freie Radikale R- und H- zerlegt.
\nBei Anwesenheit von molekularem Sauerstoff reagiert das freie Radikal mit dem Sauerstoff zu einem Peroxidradikal, und dieses Peroxidradikal reagiert mit dem Fettmolek\u00fcl zu Hydroperoxid und dem Radikal R-, das dann durch die Kettenreaktion des Radikals R- weitergegeben wird, bis die Kombination von freien Radikalen und freien Radikalen oder freien Radikalen und Radikalinaktivatoren (bezeichnet mit x) eine stabile Verbindung ergibt, und dann endet die Reaktion.
\nBei diesem Prozess entstehen viele kurzkettige Carbonylverbindungen wie Aldehyde, Ketone und Carbons\u00e4uren, die die Hauptursachen f\u00fcr Ranzigkeit und schlechten Geschmack sind, sowie gro\u00dfe Mengen an Peroxiden, die ebenfalls negative Auswirkungen auf den menschlichen K\u00f6rper haben k\u00f6nnen.
\nDer Mechanismus der Wirkung von Antioxidantien ist vor allem auf die Beendigung der \u00dcbertragung von Kettenreaktion, das Muster ist wie folgt (mit AH f\u00fcr Antioxidans): Antioxidans Radikal A- ist inaktiv, die nicht dazu f\u00fchren, dass die Kettenreaktion, kann aber in einigen Abbruchreaktionen teilnehmen. Zum Beispiel: A- A-\u2192AA A- ROO-\u2192ROOA_.
\nOleoresin antioxidants mainly include butylhydroxyanisole (BHA), dibutylhydroxytoluene (BHT), propyl gallate (PG), tert-butylhydroquinone (TBHQ<\/a>), tocopherol (vitamin E), etc. They all belong to phenolic antioxidants, which are more stable after the formation of free radicals, and the reason for this can be explained as follows: the unpaired singlet electrons on the oxygen atoms can act with the \u03c0-electron cloud on the benzene ring, which occurs a Conjugation effect. The result of this conjugation is that the paired electrons are not fixed on the oxygen atom, but are partially distributed to the benzene ring. In this way, the energy of the free radicals is reduced and no longer triggers a chain reaction, providing an antioxidant effect.
\nHemmung der enzymatischen oxidativen Br\u00e4unung von Lebensmitteln
\nBei der enzymatischen oxidativen Br\u00e4unung handelt es sich um eine Klasse von Reaktionen, bei denen Phenoloxidasen in Lebensmitteln die Oxidation von phenolischen Stoffen zu Chinonen und ihren Polymeren katalysieren. Da bei der Reaktion melanin\u00e4hnliche Stoffe entstehen, wird die Farbe des Lebensmittels vertieft, was sich auf das Aussehen und die Qualit\u00e4t des Lebensmittels auswirkt.
\nDie enzymatische oxidative Br\u00e4unung erfordert drei Bedingungen: Phenoloxidase, Sauerstoff und geeignete phenolische Substanzen. Daher kann die Hemmung der enzymatischen Br\u00e4unung von Lebensmitteln anhand dieser drei Bedingungen betrachtet werden. Da es nicht m\u00f6glich ist, die phenolischen Substanzen aus den Lebensmitteln zu entfernen, sind die wichtigsten Ma\u00dfnahmen, die eingesetzt werden k\u00f6nnen, die Zerst\u00f6rung und Hemmung der Aktivit\u00e4t der Phenoloxidase und die Beseitigung von Sauerstoff. Die Zugabe angemessener Mengen von Antioxidantien zu Lebensmitteln dient dazu, die enzymatische oxidative Br\u00e4unung von Lebensmitteln zu verhindern, indem der Sauerstoff im Lebensmittelsystem durch Reduktion verbraucht wird.<\/p>\n
