No ke aha i hoʻohui ʻia ai ka sodium benzoate i ka meaʻai?

ʻO ka hoʻomohala ʻana o ka ʻoihana meaʻai ua alakaʻi i ka hoʻomohala ʻana o nā mea hoʻohui meaʻai.Papa meaʻai sodium benzoateʻo ia ka mea mālama meaʻai lōʻihi loa a hoʻohana nui ʻia a hoʻohana nui ʻia i nā huahana meaʻai. Akā aia ka ʻawahia, no laila No ke aha i loko o ka meaʻai ka sodium benzoate?

Sodium benzoatehe fungicide organik a ʻo kona hopena pale maikaʻi loa ma ka pae pH o 2.5 - 4. Ke pH > 5.5, ʻaʻole ia e kūʻē i nā ʻōpala a me nā mea hū he nui. ʻO ka palena iki o ka benzoic acid he 0.05% - 0.1%. Hoʻoheheʻe ʻia ka ʻawaʻawa o ia mea i loko o ke akepaʻa ke komo i loko o ke kino. Aia nā hōʻike honua o ka lāʻau make i hoʻopili ʻia mai ka hoʻohana ʻana osodium benzoate ma ke ʻano he mea mālamaʻOiai ʻaʻohe ʻike like ʻia, ma kekahi mau ʻāina a me nā wahi i pāpā ʻia ai nā meaʻai i loko o ka pahu me ia, e like me ʻAmelika Hui Pū ʻIa, Iapana, a me Hong Kong. Hoʻohana nui ʻia ka Potassium sorbate, ka mea ʻawahia ʻole. No ka mea, ʻaʻole maikaʻi ka solubility i ka wai, no laila ua hana ʻia ia i mea maikaʻi ka solubility i ka wai o ka sodium benzoate. Hoʻohana nui ʻia ia no ka mālama ʻana a me ka pale ʻana i ka ʻōpala i nā huahana e like me ka soy sauce, ka vīnega, nā pickles, a me nā mea inu carbonated.

I ka nānā ʻana i nā hopohopo palekana, ʻoiai he nui nā ʻāina e ʻae nei i ka sodium benzoate ma ke ʻano he mea mālama i hoʻohui ʻia i ka meaʻai, ua lilo ka laulā o ka hoʻohana ʻana i mea haiki a ua nānā pono ʻia ka nui o ka mea hoʻohui. Ma USA, ʻo ka hoʻohana ʻana i ʻae ʻia he 0.1 wt%. ʻO ke kūlana palekana meaʻai aupuni Kina o kēia manawa ʻo GB2760-2016 "Standard for the use of food additives" e kau ana i kahi palena no ka hoʻohana ʻana i ka "benzoic acid and its sodium salt", me ka palena kiʻekiʻe o 0.2g/kg no nā mea inu carbonated, 1.0g/kg no nā mea inu mea kanu a me 1.0g/kg no nā mea inu huaʻai a me nā mea kanu (pulp). ʻO ke kumu o ka hoʻohui ʻana i nā mea mālama meaʻai, ʻo ia ka hoʻomaikaʻi ʻana i ka maikaʻi o ka meaʻai, hoʻolōʻihi i ke ola o ka papa, hoʻomaʻalahi i ka hana ʻana a mālama i ka ʻike meaʻai. ʻAe ʻia a palekana ka hoʻohui ʻana o ka sodium benzoate inā e hana ʻia e like me ka laulā o nā ʻano a me ka nui o ka hoʻohana i kau ʻia e ka mokuʻāina.
