ʻO ka hoʻolauna ʻana o ka Monascus Red Colourant:

ʻO ka Monascus Red Colorant kahi mea hoʻoluʻu kūlohelohe i unuhi ʻia mai ka laiki hū ʻulaʻula me ka hoʻohana ʻana i ka biotechnology hou, he pigment kūlohelohe ia ma waho aʻe o ka pigment caramel, a he pigment hua pigment kūlohelohe. Ma muli o kona hoʻohana ʻana, hiki ke hoʻokaʻawale ʻia i ʻelua mau ʻano i hoʻoheheʻe ʻia i ka aila a me ka wai, ʻo ia hoʻi, ʻoi aku ka nui o ka hoʻohana ʻana i ka wai, kiʻekiʻe ke kumukūʻai kala, hue kūlohelohe, a me ka ikaika o ka protein.
Nā ʻano o ka pigment erythrosine
1. Paʻa o ka waikawa-kumu
ʻOi aku ka paʻa o ka Monascus Red Colorant ma ka pae pH 4.5~12. Ke hoʻohālikelike ʻia me nā mea hoʻoluʻu kūlohelohe ʻē aʻe, ʻoi aku ka paʻa i ka pH, a he maʻemaʻe ke kala, ʻaʻole e like me kekahi mau pigments kūlohelohe e loli me ka pH.
2 Ke kūpaʻa wela
ʻOi aku ka paʻa o ke kala ma lalo o 130 ℃, akā ma luna o 130 ℃, e ʻeleʻele ka pigment.
3. Ke kū'ē ʻana i ka mālamalama
Ua hōʻike ʻia nā noiʻi he paʻa loa ka pigment ʻulaʻula ʻulaʻula i ka mālamalama o kēlā me kēia lā, a ua paʻa loa ka hopena ethanol pigment ʻulaʻula i ka mālamalama ultraviolet, inā ʻoi aku ka paʻa o ka mālama ʻana i ke kukui, ʻaʻole e loli ke kala i kekahi mau mahina, akā i ka lā pololei ikaika, ua nāwaliwali ke kūpaʻa o ke kala.
4. Ke kū'ē ʻana i ka oxidation a me ka hōʻemi
ʻAʻole kokoke i hoʻopilikia ʻia ka Monascus Red Colorant e ka 0.1% o ka hydrogen peroxide, ka huaora C a me ka sodium sulfite a me nā mea redox ʻē aʻe.
5. Ke kū'ē ʻana i nā iona metala
ʻAʻole hoʻopilikia ʻia ka Monascus Red Colorant e nā ion metala, hōʻike ka noiʻi o kēia manawa: i ke alo o Ca2+, Ma2+, Fe3+, Cu2+ mau kūlana, ʻo ke koena o kona pigment he 97% maloʻo nui, kūpono kēia ʻano i kāna hoʻohana ʻana i ka hana ʻana o nā huahana ʻiʻo, ʻaʻohe pono e hopohopo e pili ana i ka mālama ʻana i ka hū ʻulaʻula o nā huahana ʻiʻo i loko o nā pahu hao a keleawe paha.
