He aha te Sodium Dehydroacetate CAS 4418-26-2?

He paura tioata mā te konutai dehydroacetate e ngāwari ana te wairewa ki te wai. He ngoikore te waikawa o te wai, ā, ka taea te tuku hau SO2 i raro i ngā āhuatanga waikawa. He whānui te whānuitanga o te matū tiaki kai a te konutai dehydroacetate, he tino ārai mate huakita hoki, ā, he tino kaha ki te aukati i te harore me te rewena. I te horopeta kotahi, he maha, he tekau rānei ngā wā teitei ake te pānga ārai mate huakita i te konutai benzoate me te pāhare pākawa waro e whakamahia whānuitia ana. Ko te mea tino nui ko te iti o te pānga ārai ki ngā huakita whakaputa waikawa, inā koa ko ngā huakita waikawa lactic.

Tono

1. He rongoā patu huakita te konutai dehydroacetate, he nui te haumaru, he whānui te whānuitanga o ngā patu huakita, ā, he kaha hoki tōna kaha patu huakita. Kāore e pāngia e te waikawa, te kawakore rānei o te kai, ā, ka taea te pupuri i te kaha patu huakita teitei i raro i ngā āhuatanga waikawa, paku kawakore rānei. He pai ake tōna kaha patu huakita i te konutai benzoate, te pāhare pākawa sorbate, te konupūmā propionate, me ētahi atu, ā, he mea tino pai hei tiaki kai.
2. Ka taea te whakamahi i te konutai dehydroacetate mō te maimoatanga mata whakarewa, te tango hinu, me te aukati i te waikura i runga i ngā mata whakarewa,
3. Ka taea hoki te whakamahi i te konutai dehydroacetate mō te tātari matū me te whakarite i ngā wai whakapūkara.
4. Ka whakamahia hoki te konutai dehydroacetate i roto i ngā mara o te hanga pepa, te hiako, ngā paninga, ngā mea whakapaipai, me ētahi atu
