Le Faʻaaogaina o le Propionic acid
O le propionic acid o se vailaʻau taua lelei ma o se vaega o le tele o isi vailaʻau lelei. E masani ona faʻaaogaina o ni meaʻai ma ni mea faʻaopoopo mo meaʻai, sosoo ai ma vailaʻau faʻaleaiga ma laʻau taua, mea manogi ma isi mea faʻapena. I le matata o meaʻai ma mea faʻaopoopo mo meaʻai, e ofoofogia le aʻafiaga o le faʻaaogaina o le propionic acid, ma o loʻo vave ona faʻateleina le faʻaaogaina. (1) Mea faʻaopoopo e folo. E mafai e le calcium propionate ma le sodium propionate ona puipuia le faʻaleagaina o meaʻai e mafua mai i gaioiga a siama, faʻalauteleina le taimi e faʻasaoina ai meaʻai, ma faʻaaogaina lelei i le faʻasaoina o falaoa ma meaʻai suamalie. (2) Mea faʻasao o saito. Ua faʻaaogaina lelei le propionic acid e puipuia ai le ele ma le pipiʻi o saito, lea e maua ai se auala fou mo le teuina o saito mo se taimi umi. (3) Mea faʻasao o meainu. Ua faʻamaonia o le propionic acid, sodium propionate ma le calcium propionate o ni mea faʻasao lelei mo meaʻai, lea e masani ona faʻaaogaina e faʻasaoina ai meaʻai mo puaʻa, povi, mamoe ma moa, e aofia ai le calcium propionate e sili ona aʻafia ai. O le zinc propionate ma le cadmium propionate i le propionate o ni polyester catalysts mo le gaosiga o le terephthalate. E tele ituaiga o propionate, faatasi ai ma a latou lava faʻaoga, e mafai ona faʻaaogaina o ni solvents, manogi, vailaʻau faʻapitoa, faʻaopoopoga teuteu, faʻaleleia resin, plasticizers faamama sikaleti, sui antiknock suauu kesi, sui antibacterial ma isi mea faapena.
Le lelei o le propionic acid
1. Mama maualuga 99.0% min
2. Faaaoga le tele o ituaiga tofo eseese.
3. O lo'o ia i matou le tusipasi ISO 9001, ISO 14001 ma le ISO22000, o lo'o ia i matou fo'i le tusipasi HACCP, o lo'o ia i matou le tusipasi Halal ma le tusipasi kosher o lenei oloa.
5. E tele lo matou gafatia, o lea la, e masani ona vave le taimi e faʻatino ai.
6. E mafai ona matou ofoina atu le 10g-50g faʻataʻitaʻiga e leai se totogi mo lau suʻega i le fale suʻesuʻe. E masani ona matou tuʻuina atu le faʻataʻitaʻiga e ala i le avefeʻau faʻavaomalo e pei o le DHL poʻo le Fedex. E vave ma faigofie.
O le teuina o le Propionic acid
1. O le afifiina o faʻataʻitaʻiga e 20g/30g/50g i le fagu.
2. O le afifiina laʻititi e 1kg /5kg /10 kg i le fagu e tasi.
3.25 kg i le talipalau (Talipalau palasitika e lelei mo mea'ai, e leai se plasticizer, lipoti fa'amaonia a isi vaega)
E mafai fo'i ona fa'apitoa le afifiina e tusa ai ma mana'oga o tagata fa'atau
Tuutuuga o le teuina o le Propionic acid:
Lapataiga mo le Teuina Teu i totonu o se faleteuoloa malūlū ma e iai le ea e fa'aleleia ai le ea. Taofi ese mai le afi ma le vevela. E le sili atu le vevela o le faleteuoloa i le 32℃, ma e le sili atu le susu o le ea i le 80%. Ia tapuni lelei le pusa. E tatau ona teuina ese mai mea e fa'aola ai le ea, mea e fa'aitiitia ai le ea ma mea fa'asusu, ma e le tatau ona fa'afefiloi. E fa'aaogaina moli e tete'e atu i le pa ma mea e fa'aleleia ai le ea. Aua le fa'aaogaina ni masini ma ni mea faigaluega e faigofie ona feilafi. E tatau ona iai ni mea faigaluega e togafitia ai fa'alavelave fa'afuase'i o le tafe ma mea talafeagai e taofia ai le tafe.
