Ke hoʻokokoke mai nei ke kauwela, ʻo ke kau kūʻai nui ʻana no nā mea inu ʻokoʻa i ka mahina piha. Ke hoʻomau nei ka mea kūʻai aku e pili ana i ka palekana o ka ipu inu a inā hiki i nā mea āpau ke hoʻokomo i ka bisphenol A (BPA). ʻO ke kākau ʻōlelo nui o ka International Food Packaging Association, ka loea mālama kaiapuni ʻo Dong Jinshi, wehewehe ʻo ka polycarbonate plastic, ka mea i hoʻokomo i ka BPA, ka mea maʻamau i hoʻohana ʻia i ka hana ʻana i nā kīʻaha palaka, ʻōmole wai, a me nā pahu meaʻai like ʻole ma muli o kāna hiʻohiʻona maʻemaʻe a paʻa. Hoʻohana pinepine ʻia ka epoxy resin me ka BPA ma ke ʻano he uhi i loko no ka ipu meaʻai a me ka mea inu, hāʻawi i ka waiwai anti-corrosion e pale aku ai i ka oxygen a me nā microorganism mai ke komo ʻana i ke kini.

He mea nui e hoʻomaopopo ʻaʻole hiki i nā mea a pau ke hoʻohui i ka BPA, no ka mea, hana kekahi i nā mea ʻē aʻe ma mua o ka plastic polycarbonate. Manaʻo ʻo Dong Jinshi i ka loaʻa ʻana o ka BPA i ka alumini a me ka hao hiki ke hoʻohana no Cola, hiki ke hua, a me nā mea kūʻai aku. Eia nō naʻe, hiki i ka hoʻohana ʻana i ka plastic BPA-free i kekahi ke hōʻoiaʻiʻo ʻaʻole nā ​​pahu a pau e lele i kahi pōʻino o ka ʻike BPA. ʻike ʻole ʻia ʻo AIPono e hoʻokomo ʻia e kōkua i ka ʻike ʻana i nā mea pale palekana.

ʻO Bisphenol A, ʻike ʻepekema ʻo 2,2-di (4-hydroxyphenyl) propane, he mea hoʻohana kemika koʻikoʻi i ka hana ʻana i nā mea polymer like ʻole, plasticizer, fire retardant, a me nā mea kūʻai kemika maikaʻi. ʻOiai ke helu ʻia ʻana ma ke ʻano he kemika haʻahaʻa haʻahaʻa, ua hōʻike ka noiʻi holoholona e hiki i ka BPA ke hoʻohālikelike i ka estrogen, alakaʻi i nā hopena ʻino e like me ka ulu ʻana o ka wahine, hoʻemi i ka helu sperm, a me ka ulu ʻana o ka prostate gland. Eia kekahi, hōʻike ia i ka ʻona embryonic a me ka teratogenicity, hāʻawi i ka piʻi nui o ka maʻi kanesa e like me ka maʻi ovarian a me ka prostate gland i nā holoholona.
