Limodzi mwa mavuto ndi chakudya chophika ndi chakuti kutentha kumapangitsa kuti mapuloteni awonongeke. Mphamvu ya kinetic yomwe imapangidwa ndi kutentha imayambitsa kugwedezeka kofulumira kwa mamolekyu a mapuloteni ndi kuwonongeka kwa zomangira zawo. Makamaka, denaturation amagwirizana ndi kuphwanya yachiwiri ndi tertiary nyumba zomanga thupi. Simaphwanya zomangira za peptide za amino acid, koma zimachitika ku ma alpha-helices ndi ma beta-mapepala akuluakulu, zomwe zimatsogolera kukonzanso kwawo kosokoneza. Denaturation pa chitsanzo cha mazira otentha - mapuloteni coagulation. Zodabwitsa ndizakuti, mankhwala ndi zida ndi chosawilitsidwa ndi kutentha denature puloteni mabakiteriya otsala pa iwo. Yankho lake ndi losamvetsetseka. Kuchokera kumalingaliro amodzi, denaturation imalola mapuloteni ovuta kuti agayike kwambiri powaphwanya kukhala maunyolo ang'onoang'ono. Kumbali inayi, chipwirikiti chomwe chimabwera chifukwa cha chipwirikiticho chingakhale maziko owopsa a ziwengo. Chitsanzo chabwino ndi mkaka. Mu mawonekedwe ake oyambirira, okonda zachilengedwe, thupi la munthu limatha kulitenga, ngakhale kuti pali zigawo zovuta za molekyulu. Komabe, chifukwa cha pasteurization ndi chithandizo cha kutentha kwambiri, timapeza mapuloteni omwe amayambitsa ziwengo. Ambiri aife tikudziwa kuti kuphika kumawononga zakudya zambiri. Kuphika, mwachitsanzo, kumawononga mavitamini B onse, vitamini C, ndi mafuta acids onse, mwina mwa kuwononga kufunikira kwake kwa zakudya kapena kutulutsa mphuno yosayenera. Chodabwitsa n'chakuti kuphika kumawonjezera kupezeka kwa zinthu zina. Mwachitsanzo, lycopene mu tomato akatenthedwa. Broccoli wowotchera ali ndi ma glucosinolates ambiri, gulu lazomera zomwe zimadziwika kuti zimakhala ndi anti-cancer. Ngakhale kutentha kumawonjezera zakudya zina, kumawononga ena.
