Ke 1000K ka mahana, aia ka diffusion coefficient o ka oxygen i loko o ke aniani soda-lime ma lalo o 10-4cm / s. Ma ka lumi wela, he mea ʻole ka diffusion o ka oxygen i loko o ke aniani; paʻa ke aniani i ka oxygen a me carbon dioxide no ka manawa lōʻihi, a ʻaʻole komo ka oxygen i ka lewa i nā kānaka.
ʻAʻole kahe ka carbon dioxide i waho o ka pia, hiki ke mālama i ka hou a me ka ʻono o ka pia. Hoʻopili ke aniani i nā kukuna ultraviolet ma lalo o 350nm, hiki ke pale i ka waina, nā mea inu, nā meaʻai, nā mea hoʻonaninani, a me nā huahana kemika i loko o ia mea mai ka hōʻino ʻia e nā hopena photochemical.
No ka laʻana, hoʻopuka ka pia i ka ʻala ma hope o ka ʻike ʻia ʻana i ke kukui 550nm, ka mea i kapa ʻia ka ʻono o ka lā. E hua mai; ma hope o ka hoʻoulu ʻia ʻana o ka waiū me ka māmā, ma muli o ka hana ʻana o nā peroxides a me nā hopena ma hope, ua hoʻokumu ʻia ka "ʻono māmā" a me ka "off-flavor", e hoʻemi ʻia ka huaora C a me ka waikawa ascorbic, a loaʻa ka huaora A, Be, a me D. nā hoʻololi like, akā aniani ʻAʻole kēia ka hihia no nā ipu.
Loaʻa i nā ʻōmole aniani nā mea ʻono e like me ka kuke ʻana i ka waina, ka vīneka, a me ka soy sauce. ʻAʻole lākou e hana i nā mea ʻala ma muli o ka hana o ka oxygen a me nā kukui ultraviolet, a ʻaʻole e pōʻino nā mea hoʻonaninani.
E kahiko a hoʻokuʻu ʻia nā pahu pahu pahu e like me ka polyethylene a me ka polypropylene ma hope o ka ʻike ʻia ʻana i nā kukuna oxygen a me nā ultraviolet. Hoʻopilikia ka polyethylene monomer i ka ʻono o ka waina, soy sauce, vīneka a me nā mea like i loko o nā ipu plastik.
