ʻO ka hoʻomaka a me ka hōʻuluʻulu ʻana o nā mea mālama hoʻonaninani

ʻO ka hoʻolālā o ka mea hoʻonaninanimea mālamaPono ka ʻōnaehana e hahai i nā loina o ka palekana, ka pono, ka pili a me ka hoʻohālikelike ʻana me nā mea ʻē aʻe i loko o ke kumu.I ka manawa like, pono e ho'āʻo ka preservative i hoʻolālā ʻia e hoʻokō i kēia mau koi:
①Ka hana antibacterial ākea ākea;
②Hoʻohālikelike maikaʻi;
③Ka palekana maikaʻi:
④Hoʻoheheʻe wai maikaʻi;
⑤Paʻa maikaʻi;
⑥Ma lalo o ka hoʻohana ʻana, pono ʻole ke kala, ʻaʻala a me ka ʻono ʻole;
⑦Kukuai haahaa.
Hiki ke hoʻokō ʻia ka hoʻolālā o ka ʻōnaehana anti-corrosion e like me nā pae aʻe:
(1) Ka nānā ʻana i nā ʻano mea mālama i hoʻohana ʻia
(2) Hoʻohui i nā mea mālama
(3) Hoʻolālā omea mālama-ʻōnaehana manuahi
Pono ka preservative maikaʻi e kāohi i nā microorganism āpau, me nā fungi (yeasts, molds), gram-positive a me nā bacteria maikaʻi ʻole.Ma keʻano laulā, ʻoi aku ka maikaʻi o ka hapa nui o nā preservatives e kūʻē i ka maʻi bacteria a i ʻole nā ​​​​hani, akā ʻaʻole hiki ke hana maikaʻi i nā mea ʻelua.ʻO ka hopena, ʻaʻole hiki ke hoʻokō ʻia ka pono o ka hana ākea ākea e ka hoʻohana ʻana i hoʻokahi preservative.ʻO ka hoʻohana ʻana i nā haʻahaʻa haʻahaʻa hiki ke kūpono a pono e hoʻopau i nā microorganism me ka wikiwiki, lawa e pale i nā hopena antagonistic o nā microorganism ma ka ʻōnaehana preservative.Hoʻemi pū ia i ka hopena o ka huhū a me ka ʻona.Pono e paʻa nā preservatives i nā wela a me ka pH i ka wā o ka hana ʻana i nā mea hoʻonaninani a i ka wā o ko lākou ola papa i manaʻo ʻia, e mālama ana i kā lākou hana antimicrobial.ʻO ka ʻoiaʻiʻo, ʻaʻohe pūhui organik i paʻa i ka wela kiʻekiʻe, a i ʻole ka pH kiʻekiʻe.Hiki ke paʻa wale nō i loko o kekahi laulā.
Me ka noiʻi hohonu e pili ana i ka palekana o nā mea hoʻomalu, ua hōʻike ʻia ka nui o nā mea mālama kuʻuna i kekahi mau hopena maikaʻi ʻole;ʻO ka hapa nui o nā mea mālama i nā hopena hoʻonāukiuki, etc.No laila, ʻo ka manaʻo o ka palekana "ʻaʻole i hoʻohui ʻia"mea mālamaua hoʻomaka nā huahana e puka mai.Akā ʻaʻole hōʻoiaʻiʻo nā huahana preservative-free i kahi ola paʻa, no laila ʻaʻole lākou i kaulana loa.Aia kahi kū'ē'ē ma waena o ka huhū a me ke ola papa, no laila pehea e hoʻoponopono ai i kēia kū'ē?Ua aʻo kekahi mau hui kaulana i kekahi mau pūhui ʻaʻole i hoʻokomo ʻia i loko o ka moʻo preservative, a ua hoʻopaʻa ʻia i kekahi mau pūhui waiʻona me ka hana preservative, e like me Hexanediol, Pentanediol, P-hydroxyacetophenone (Helu CAS 70161-44-3), Ethylhexylglycerin (CAS No.70445-33-9),CHA Caprylhydroxamic Acid ( Helu CAS 7377-03-9) etc., ke hoʻohana ʻia kēia mau pūhui i nā huina kūpono i ka huahana, hiki ke hoʻokō i nā hopena preservative maikaʻi a hele i ka hoʻāʻo hoʻokūkū preservative.
