Loaʻa i nā puaʻa mea kanu nā ʻano mole like ʻole, porphyrins, carotenoids, anthocyanins a me betalains.
ʻO ke ala kuʻuna o ka unuhi ʻana i ka puaʻa mea kanu:
ʻO ka mea mua, lawe ʻia ka crude extract i loko o ka solvent organik, a laila hoʻomaʻemaʻe ʻia me ka resin a i ʻole nā kaʻina hana ʻē aʻe, a laila e hoʻoheheʻe ʻia a hoʻopaʻa ʻia i kahi haʻahaʻa haʻahaʻa.He paʻakikī ke kaʻina hana, paʻakikī ke kāohi, nui ka nui o nā mea hoʻoheheʻe organik a me ke ʻano resin, ka hoʻohana ʻana i ka waikawa a me ka alkali, nā koina hana kiʻekiʻe, ka polluted environment, unstalbe pigment quality, low color value.
ʻO ka hoʻohana ʻana i ka hoʻokaʻawale ʻana o ka membrane a me ke kaʻina hoʻomaʻemaʻe hiki ke maʻalahi i ke kaʻina holoʻokoʻa, e mālama i nā mea hoʻoheheʻe organik.Hiki i ke kaʻina hana Ultrafiltration ke wehe i ka protein, starch a me nā mea haumia ʻē aʻe, a laila hoʻoneʻe ʻia e ka nanofiltration e hoʻoneʻe i nā moleke liʻiliʻi, ʻoiai e paʻa ana.Hiki ke ho'okō 'ia ka mana 'akomi, e ho'emi nui ana i nā kumukū'ai o ka unuhi, ka maika'i o ka pua'a a me ke kūpa'a a me ka waiwai kala ki'eki'e.Hoʻohana ʻia ia i ka hana ʻana i nā mea kanu lāʻau.
