ʻO ka Sodium Carboxymethyl Cellulose (CMC)ʻO ia kahi derivative cellulose kūlohelohe i hoʻololi ʻia i ka kemika, kahi i hoʻohana nui ʻia i ka meaʻai, nā lāʻau lapaʻau a me nā ʻoihana kemika o kēlā me kēia lā. ʻO ka CMC papa meaʻai, ma ke ʻano he ʻano polymer colloid, ke hana nui nei i nā kuleana o ka hoʻomānoanoa, ka hoʻopaʻa ʻana, ka paʻa ʻana i ka wai, ka emulsification a me ka hoʻokumu ʻana i nā kiʻiʻoniʻoni i ka ʻoihana meaʻai. Ma muli o kona palekana maikaʻi loa a me nā waiwai hana koʻikoʻi, ua lilo ʻo CMC i hoʻokahi o nā mea polysaccharide makua loa i hoʻohana ʻia i nā mea hoʻohui meaʻai.
1. Ka loiloi palekana o ka CMC papa meaʻai
Hana ʻia ka CMC papa meaʻai mai ka cellulose mea kanu kūlohelohe ma ke ʻano he mea maka a hoʻopuka i nā huahana carboxymethylated ma o nā hopena etherification. Paʻa kona ʻano a ʻaʻole maʻalahi ke komo a hoʻoheheʻe ʻia e ke kino kanaka, no laila he palekana physiological kiʻekiʻe. Ua hoʻokomo ka World Health Organization (WHO) a me ka Food and Agriculture Organization of the United Nations (FAO) iā CMC i ka papa inoa o nā "mea hoʻohui meaʻai palekana no ka hoʻohana ʻana", a ua hana pū ka Codex Alimentarius Commission i nā lula maopopo e pili ana i kona maʻemaʻe a me ka laulā o ka hoʻohana ʻana.
Ma ke ʻano o ka noiʻi toxicological, ua hōʻike ka nui o nā hopena hoʻokolohua ʻaʻohe ʻawaʻawa koʻikoʻi o CMC, ʻaʻohe mutagenicity, ʻaʻohe teratogenicity, a ʻaʻohe hopena physiological maopopo i nā ʻōpū holoholona a kanaka paha. ʻAʻole komo ka CMC i loko o ke kino a hoʻokuʻu nui ʻia ma kona ʻano kumu, no laila ʻaʻole ia e hoʻoulu i ka ukana metabolic a hōʻiliʻili paha i ka ʻawaʻawa. Ua hoʻokaʻawale ka FDA o ʻAmelika Hui Pū ʻIa iā ia ma ke ʻano he GRAS (Generally Recognised As Safe, generally considered safe) substance, e ʻae ana iā ia e hoʻohana nui ʻia i ka meaʻai.
Loaʻa i ka CMC papa meaʻai ka mana koʻikoʻi ma luna o nā koena o nā metala kaumaha, nā chlorides a me nā mea hoʻoheheʻe organik i ka wā o ka hana ʻana. ʻOi aku kona maʻemaʻe ma mua o 99% a ua hala i nā hoʻāʻo maʻemaʻe koʻikoʻi. Inā hoʻohana ʻia i loko o ka laulā i kuhikuhi ʻia a me ka nui e ka mokuʻāina a i ʻole ma ka honua holoʻokoʻa, palekana loa ka lawe ʻana o CMC.
2. Nā ʻano hana o ka CMC papa meaʻai
2.1. Nā hopena mānoanoa a me ka hoʻopaʻa ʻana
Loaʻa i ka molekole CMC kahi nui o nā hui carboxymethyl a me hydroxyl, hiki ke hana i nā pilina hydrogen ikaika me nā molekole wai a hōʻike i ka hydrophilicity koʻikoʻi a me ka waiwai pehu. I loko o nā ʻōnaehana meaʻai, ʻoiai ke hoʻohui ʻia i nā ʻano haʻahaʻa, hiki iā ia ke hoʻonui nui i ka viscosity o ka ʻōnaehana, hana i kahi ʻano wai like, a pēlā e hoʻomaikaʻi ai i ka ʻono a me ke ʻano o ka huahana. I kēia manawa, loaʻa i ka CMC ke kūpaʻa ionic maikaʻi loa a hiki ke mālama i ka paʻa o ka viscosity i nā wahi acidic, alkaline a i ʻole ka paʻakai kiʻekiʻe. Hoʻohana pinepine ʻia i nā huahana waiū, nā mea inu wai huaʻai a me nā mea ʻono e pale aku i ka stratification a me ka precipitation.
2.2. Nā waiwai paʻa wai a me ka pale ʻana i ka ua
Hiki i ka CMC ke hui pū me ka makū, e hōʻemi ana i ka neʻe ʻana o ka makū a me ka hoʻopaʻa ʻana o ka meaʻai i ka wā e mālama ai a i ʻole ka hoʻopaʻa ʻana. No ka laʻana, i nā meaʻai hau a me nā mea i hoʻomoʻa ʻia, hiki i ka waiwai paʻa wai o CMC ke pale i ka nahā a me ka paʻakikī, hoʻolōʻihi i ke ola o ka papa, a mālama i ka palupalu a me ka hou o nā huahana.
2.3. Nā waiwai emulsification a me ka hoʻokuʻu ʻana
Hiki i ka CMC ke hana i kahi ʻili viscoelastic ma ka pilina ʻaila-wai, e hoʻoikaika ana i ke kūpaʻa o ka ʻōnaehana emulsification a pale i ka ʻaila mai ka lana ʻana a i ʻole ka stratifying. No laila, hoʻohana pinepine ʻia ia i nā huahana e like me ka ice cream, nā ʻaʻahu salakeke, a me nā mea inu waiū, e hana pū ana me nā emulsifiers e hoʻokō i kahi ʻano maikaʻi a paʻa.
2.4.. Nā waiwai hana kiʻiʻoniʻoni a me ka uhi ʻana
He mau waiwai hana ʻili maikaʻi loa ko CMC a hiki ke hana i kahi ʻili moakaka ma luna o ka ʻili o ka meaʻai. Hoʻohana ʻia ia no ka uhi ʻana i nā huaʻai, nā kinikini a i ʻole nā pauka koke, e pāʻani ana i kahi hana i ka pale ʻana i ka makū, ka pale ʻana i ka oxidation a me ka hoʻopaneʻe ʻana i ka palaho. I loko o ka pauka inu koke a me ka pauka ʻono, hiki i ka CMC ke pale i ka caking a hoʻomaikaʻi i ka solubility.
2.5. Hoʻomaikaʻi i ka ʻono a me ke ʻano
Hiki i ka CMC ke hāʻawi i ka meaʻai i kahi ʻano laumania a mānoanoa a hoʻomaikaʻi i nā waiwai rheological o ka huahana. No ka laʻana, i loko o ka yogurt a me ka jelly, hiki i ka CMC ke hoʻonui i ka mānoanoa, hāʻawi i kahi ʻano maikaʻi a hoʻomaikaʻi i ka ʻike ʻono o nā mea kūʻai.
3. Nā kahua noi o ka CMC papa meaʻai
Māhele mea inu: Kāohi i ka sedimentation a me ka stratification i nā mea inu wai huaʻai a me nā mea inu protein, a hoʻomaikaʻi i ke kahe a me ka ʻono.
Nā huahana waiū: Hoʻohana ʻia i loko o ka hau kalima a me ka yogurt e hoʻoikaika i ke kūlike a pale i ka hoʻokumu ʻia ʻana o nā kristal hau, e hoʻomaikaʻi ana i ka laumania o ka maikaʻi o ka waiū.
Nā mea i hoʻomoʻa ʻia: Hoʻonui i ka paʻa ʻana o ka wai a me ke kūpaʻa o ke ʻano o ka palaoa i loko o ka berena a me nā keke, a hoʻolōʻihi i ka manawa palupalu.
Nā mea ʻala a me ka mea ʻono soy: E pale i ka hoʻokaʻawale ʻana o ka aila a me ka wai, e hoʻonui i ka luster a me ka hoʻopili ʻana i ka paia.
Nā kinikini a me nā meaʻai koke: Ma ke ʻano he mea uhi a me ka mea anti-caking, hoʻomaikaʻi ia i ke ʻano a me ka solubility.
CMC papa meaʻaiHe polysaccharide kūlohelohe palekana, hilinaʻi a hana piha. ʻO kona mau waiwai hoʻomānoanoa, hoʻopaʻa, mālama wai, emulsifying a me ke ʻano hana kiʻiʻoniʻoni maikaʻi loa e paʻa ai i kahi kūlana i hiki ʻole ke pani ʻia i ka ʻoihana meaʻai hou. Mai kahi hiʻohiʻona palekana, ua hōʻoia ʻia ʻo CMC e nā ʻoihana mana he nui ma ka honua holoʻokoʻa a ua ʻike ʻia he mea hoʻohui meaʻai ʻaʻohe ʻawaʻawa, ʻaʻohe allergenic, a hiki ke hoʻohana ʻia no ka manawa lōʻihi. I ka hoʻomau ʻana o ka hopohopo o ka poʻe no ka maikaʻi o ka meaʻai a me ke olakino, e hoʻonui hou ʻia nā kahua noi o ka CMC papa meaʻai, a e hoʻomau ʻia ka hōʻike ʻana i kona mau pono hana i nā lepili maʻemaʻe, nā meaʻai haʻahaʻa momona a me nā huahana mea kanu.
