Ho?ohana nui ?ia ka Potassium Sorbate ma ke ?ano he Preservatives ma nā ?āina he nui
Ho?olauna
?O ke ke?oke?o a hiki i ka melemele ?ula?ula ?ula?ula, ka pauka crystalline, a i ?ole ka ?āpana. ?A?ala ?ole a ?ala iki paha. ?O ka mālama ?ana i ka wā lō?ihi i ka lewa, ma?alahi ke komo i ka makū a me ka decomposition oxidative a me ke kala. Māmā pili (d2025): 1.363. Ka helu hehe?e 270 °c (decomposition). Hiki i ka wai (67.6g/100ml, 20 °C), 5% wai pa?akai (47.5g/100ml, lumi wela), 25% wai kō (5Chemicalbooklg/100ml, lumi wela). Hiki ke ho?ohehe?e ?ia i loko o propylene glycol (5.8g/100m1), ethanol (0.3g/100m1). ?O ka pH waiwai o 1% aqueous solution he 7 ~ 8. He hopena ko?iko?i ia o ka pale ?ana i ka bacteria spoilage a me ka ?ōpala, a no ka mea ?oi aku ka ha?aha?a o ka ?awa?awa ma mua o nā preservatives ?ē a?e, ua lilo ia i mea mālama nui o ka honua. Ma lalo o nā kūlana acidic, hiki iā ia ke hā?awi i ka pā?ani piha i ka hopena antiseptic, a ha?aha?a loa ka hopena i ka wā kū ?ole

ho?ohana
1) Ho?ohana nui ?ia ma ke ?ano he preservative i ka ?oihana mea?ai, hiki iā ia ke ho?onui i ke ola o ka mea?ai.
2) Loa?a iā ia nā hopena antibacterial maika?i e kū?ē i ka mold, aerobic spore e hana ana i ka bacteria, a me ka gram-negative bacteria, a ?a?ole ?ino ka hū.
3) Hiki i kēia huahana ke pale i ka hana ?ana o ka aflatoxin a ho?ohana nui ?ia no ka pale ?ana a me ka mālama ?ana i ka berena, pastries, soy sauce, soy products, jam, a me nā mea?ai canned.
4) Ua helu ?ia e ka propionic acid, ?o ka nui o ka calcium propionate i ho?ohana ?ia i nā huahana noodle pulu (?oki ?ia nā noodles, ?ili Wonton) he 0.25g/kg; ?O ka nui o ka ho?ohana ?ana i ka berena, ka vīnega, ka soy sauce, nā pastries, a me nā huahana soy he 2.5g/kg.
5) Ho?ohana pū ?ia ka calcium propionate ma ke ?ano he mea mālama hānai;
6) Hiki ke ho?ohana ?ia no nā lā?au lapa?au, hana i nā wai, pauka, ?aila, etc.
7) He hopena maika?i nō ho?i ia i nā ma?i ?ili i ho?okumu ?ia e ka pala.
8) Loa?a i ka calcium propionate ka hopena o ka ho?oikaika ?ana i ka calcium, no laila hiki ke ho?ohana ?ia e ho?ohui i ka calcium i nā mea?ai e like me ka berena.
9) Hiki i ka calcium propionate ke kāohi i ka hana hou ?ana o Bacillus subtilis i ka wā o ka fermentation palaoa. ?O ka ha?aha?a ha?aha?a ha?aha?a he 0.01% ma kahi pH o 5.0, 0.188% ma kahi pH o 5.8, a ?o ka pH maika?i loa ma lalo o 5.5.
