  • Cinnamic Acid CAS 621-82-9

    ʻO Cinnamic Acid CAS 621-82-9

    ʻO ka waikawa cinnamic kahi hui kūmole me ka mana C6H5CH = CHCOOH. He hui crystalline keʻokeʻo keʻokeʻo ia e hiki ke hoʻoheheʻe ʻia i ka wai, a maʻalahi hiki ʻole ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe kūlohelohe Hoʻonohonoho ʻia e like me kahi waikawa carboxylic unsaturated, kū maoli ia i nā mea kanu. Aia ia ma ke ʻano he cis a me kahi trans isomer, ʻoiai ʻo ka hope ka mea maʻamau.

  • Maltol CAS118-71-8

    Maltol CAS118-71-8

    ʻO Maltol kahi hui kūlohelohe kūlohelohe i hoʻohana mua ʻia ma ke ʻano he flavesancancer. ʻIke ʻia i ka ʻili o ka lāʻau larch, i nā nila kui, a i ka malt i hoʻomoʻa ʻia (kahi e loaʻa ai ka inoa). ʻO ia kahi pauka crystalline keʻokeʻo e hiki ke hoʻoheheʻe ʻia i ka wai wela, chloroform, a me nā mea hoʻoheheʻe polar ʻē aʻe. Ma muli o kona ʻala o ka pulupulu a me ka caramel, hoʻohana ʻia ka maltol e hāʻawi i kahi ʻala onaona i nā ʻala. Hoʻohui ka momona a Maltol i ka pilau o ka palaoa i hoʻomoʻa ʻia hou ʻia, a hoʻohana ʻia me kahi mea hoʻonui ʻono (INS Helu 636) i nā berena a me nā palaoa. ʻAʻole ia i hoʻopaʻa inoa ʻia ma ke ʻano he mea hoʻohui meaʻai ma ka EU a no laila ʻaʻohe helu E-helu. Akā, ua hoʻopaʻa inoa ʻia ka maltol ma ke ʻano he ʻono o ka EU.
