Me ka hiki ʻana mai o ke kauwela, nā ʻano mea inu a pau i ke kau kūʻai, nui nā mea kūʻai aku e nīnau nei: ʻo wai ka ʻōmole inu ʻoi aku ka palekana? Loaʻa i nā kini a pau ka BPA?
ʻ
Ua haʻi aku ke kākau ʻōlelo nui o ka International Food Packaging Association, ka loea hoʻomalu kaiapuni ʻo Dong Jinshi i ka poʻe nūhou, ʻo ka polycarbonate plastic i loaʻa ka bisphenol A he maʻemaʻe, ʻaʻole maʻalahi ke haki a me nā ʻano ʻē aʻe. Hoʻohana nā mea hana iā ia e hana i nā lako like ʻole, e like me ka papa ʻaina plastik, nā ʻōmole wai plastik, nā ʻōmole pēpē, nā kīʻaha meaʻai, a me nā mea ʻē aʻe. ʻO ke kumu i loaʻa ai ka bisphenol A i ka pahu pahu pahu o nā kini hao a me nā kini aluminika, ʻo ia ka bisphenol A he hopena anti-corrosion maikaʻi a hiki ke pale pono i ka oxygen a me nā microorganism mai ke komo ʻana i ke kini.
ʻ
Hoʻomanaʻo ʻo Dong Jinshi, i kēia manawa aia ka bisphenol A ʻaʻole wale ka alumini hiki ke cola, me ka ipu hao,pahu alumini hikio ewalu waiwai poruel, canned hua a pela aku no hoi ka bisphenol A. Eia naʻe, ua kuhikuhi pū ʻo Dong Jinshi ʻaʻole kēia manaʻo he BPA nā kini a pau, ua hana ʻia kekahi mau kini i ka plastic, ʻoiai ʻaʻole i hana ʻia me PC. ʻo ka plastic, ʻaʻole lākou i loko o ka BPA.

Introduction to Chemistry
ʻ
ʻO Bisphenol A, ka inoa ʻepekema o 2, 2-di (4-hydroxyphenyl) propane, he mea koʻikoʻi koʻikoʻi kemika, phenol a me ka acetone nā derivatives koʻikoʻi o ka bisphenol. resin, polysulfone resin, polyphenyl ether resin, unsaturated polyester resin a me nā mea polymer ʻē aʻe. Hiki ke hoʻohana ʻia i ka hana ʻana i ka plasticizer, flame retardant, antioxidant, heat stabilizer, rubber antioxidant, pesticide, pena a me nā huahana kemika maikaʻi.
ʻ
Hōʻike ka ʻikepili he mea ʻawaʻawa haʻahaʻa ka bisphenol A. Ua ʻike ʻia nā hoʻāʻo holoholona he hopena ka bisphenol A i ka hoʻohālikelike ʻana i ka estrogen, ʻoiai inā he haʻahaʻa loa ka nui, hiki iā ia ke hana i ka holoholona i ka hānau mua ʻana o ka wahine, emi ka helu sperm, ulu prostate a me nā hopena ʻē aʻe. Eia kekahi, ua hōʻike ʻia aia ka bisphenol A i kekahi mau meaʻawaʻawa embryonic a me teratogenicity, hiki ke hoʻonui nui i ka hiki ʻana o ka maʻi maʻi ovarian, prostate cancer, leukemia a me nā maʻi maʻi ʻē aʻe i nā holoholona.

Pehea e koho ai i nā mea inu canned non-bisphenol A
ʻ
ʻAʻole nalo ka mākeke no ka bisphenol A, a hiki i nā pōʻino o ka bisphenol A. No laila, ʻo wai ka ʻeke i ʻoi aku ka palekana ma ka mākeke? Pehea e ʻike ai i nā huahana plastik i loaʻa ka bisphenol A?
ʻ
I ke koho ʻana i kahi mea inu kīʻaha, he mea nui ka heluhelu ʻana i nā helu ma ka hōʻailona triangular ma lalo o ka hue plastik. No ka mea e hōʻike ana kēlā me kēia helu i kahi mea plastik, nā mea like ʻole, nā hana like ʻole, ʻokoʻa nā kūlana hoʻohana palekana.
ʻ
Wahi a ke kūlana aupuni, ʻo “1″ ke kū nei no PET(polyethylene terephthalate), ka mea maʻamau i hoʻohana ʻia i loko o nā hue wai minerala a me nā ʻōmole inu kalapona. Heat resistant 70 ℃, kūpono wale no nā mea inu wela a i ʻole nā ​​mea inu maloʻo, ʻoi aku ka maʻalahi o ka wai wela i ka deformation, hiki i ka hoʻohana pinepine ʻana ke hoʻokuʻu i nā kinoea ʻino; ʻO “3″ ka PVC(7810,15.00,0.19%) (polyvinyl chloride), ʻaʻole hiki ke hoʻohana ʻia i ka ʻeke meaʻai; “4″ e hōʻike ana i ka LDPE (polyethylene haʻahaʻa haʻahaʻa), hoʻohana ʻia no ke kiʻi ʻoniʻoni, kiʻiʻoniʻoni plastik, a me nā mea ʻē aʻe, ke hālāwai ʻo ia me 110 ℃, e loaʻa kahi hanana heheʻe wela, no laila ma mua o ka hoʻohana ʻana i ka umu microwave, e hōʻoia e wehe i ke kiʻi paʻa meaʻai. ka mua; ʻO “5″ ke kū nei no PP(polypropylene), i hoʻohana ʻia i loko o nā pahu ʻaina awakea microwave a hiki ke wela; ʻO 6″ no PS(polystyrene), i hoʻohana ʻia no ka hana ʻana i nā kīʻaha o nā pahu noodle koke a me nā pahu meaʻai wikiwiki, akā ʻaʻole hiki ke hoʻomehana ʻia i ka umu microwave, ʻaʻole hiki ke hoʻohana ʻia e hoʻouka i ka waika ikaika a me nā mea alkaline; ʻO ka "7" ke kū nei i ka polycarbonate (PC) a me nā ʻano ʻano ʻē aʻe, ʻo ia hoʻi, inā he 7 ka helu ma ka triangle, pono e loaʻa iā BPA.

ʻO mākou hehiki ke aluminiʻO ka mea kūʻai aku ma mua o 15 mau makahiki, hiki i nā makahiki he nui o ka alumini ke hana i ka ʻike, ke hoʻolohe nei mākou i ka palekana o ka meaʻai, no ka mea hiki ke uhi ʻia ke alumini, ka hoʻohana ʻana i nā mea hoʻonaninani kūloko e like me nā kūlana aupuni, e hōʻoia i ka palekana, ʻo ia hoʻi. huaHiki ke alumini ʻole BPA, hoʻokipa i nā mea kūʻai mai nā ʻāina āpau e hele mai e kūkākūkā
