?O ka mea?ai he waiwai nui i ka protein, carbohydrates a me nā mea momona momona, ma lalo o ka hana o ke kino, kemika a me nā mea olaola, e nalowale ke kala kumu, ka ?ala, ka ?ono, ke ?ano a me ka palaho, i waena o ka hana o nā microorganisms ?ino ke kumu nui o ka pala a me ka deterioration.
Ma mua o ka hana ?enehana, ho?ohana ma?amau nā kānaka i nā ?ano ku?una e like me ka malo?o, ka pa?akai, ke kō, ka fermentation e mālama ai i ka mea?ai. Me ka ho?omohala ?ana o ka ?oihana mea?ai hou, ?oi aku ka nui o nā ?enehana hou no ka mālama ?ana i ka mea?ai, e like me ka canning, vacuum packaging, pneumatic conditioning packaging a me nā ?ano ?āpana ?ē a?e, akā me ka ho?ohana ?ana i nā ?enehana sterilization like ?ole, e like me autoclaving, irradiation sterilization, electron beam sterilization, mālama ?ia i ka friji, mālama ?ia a me nā ?ano ?ē a?e.
Eia nō na?e, ?a?ohe o ka ?enehana i ho?ohana ?ia, ?a?ole ia he na?aupō, no laila, no ka hapa nui o nā mea?ai, ?o ka ho?ohana ?ana i nā preservatives ma ke ?ano he laina ?elua o ka pale e hō?oia i ke ola o ka mea?ai.
?O ka ?akika lactic (lactic acid) ka pa?akai sodium o ka waikawa lactic. ?A?ole waiho?olu?u a i ?ole melemele li?ili?i ka wai aniani, ?a?ohe ?ala, pa?akai li?ili?i ka ?ono ?awa?awa, hui pū ?ia me ka wai, ethanol, glycerin.
I ka ?oihana mea?ai, ho?ohana nui ?ia ia e like me ka mea ?ono, ka mea ho?oponopono acidity a me ka humectant. Ma muli o ka hopena o ka sodium lactate i ka ho'ēmi?ana i ka hana wai o ka mea?ai, hiki iā ia ke ho?onui i ke ola o ka mea?ai, a ho?ohana?ia ia ma ke?ano he mea?ai no ka mālama?ana i nā mea?ai.
?O ka hana mālama o ka lactic acid a me ka sodium lactate
Ma ke?ano laulā, ?oi aku ka ki?eki?e o ka ?ona o nā waikona i loko o ka moku?āina non-dissociated, ?oi aku ka ikaika o ka hiki ke antibacterial (no ka mea, ?oi aku ka ma?alahi o nā waikawa organik i ka moku?āina non-dissociated ma?alahi i ka membrane cell bacteria a komo i ke kino o ke kino), ?o ka ho?oma?ema?e ?ana o ka lactate ions (H) mai ka cell e ho?opau i ka ikehu, ho?emi i ka metabolism cell, a pēlā e pale ai i ka ulu ?ana o ka bacteria.
?O ka hopena preservative o ka sodium lactate he ?elua kumu: 1. ?O ka ho?ohui ?ana o ka sodium lactate hiki ke hō?emi i ka hana wai o ka huahana, a laila e pale ai i ka ulu ?ana o nā microorganisms. 2. He hui hana antibacterial ka lactate ion. ?O ka lactic acid pono?ī he hopena pale kūikawā i ka ulu a me ka hana hou ?ana o nā microorganism.
?O ka ho?ohana ?ana i ka sodium lactate
?O 60% -80% ka mana?o nui, a ?o ka palena ho?ohana ki?eki?e o 60% ?o ka 30g/KG. Ho?ohana ?ia i ka ?i?o a me nā huahana moa, he hopena pa?a ikaika ia i ka ?ai mea?ai bacteria, e like me E. coli, clostridium botulinum, listeria a pēlā aku. Ma o ka pale ?ana i ka mea?ai pathogenic bacteria, i mea e ho?onui ai i ka palekana o ka mea?ai. Ho?onui a ho?omaika?i i ka ?ono o ka ?i?o, ho?onui i ke ola o ka papa.
?O ka sodium lactate i loko o ka ?i?o maka he maika?i ka ho?opuehu ?ana, a he maika?i ka absorption o ka wai, i mea e pale pono ai i ka dehydration o ka ?i?o maka, e ho?okō i ka hou, ka hopena mālama mālama. Ho?ohana nui ?ia ia no ka ?i?o kālua, ham, sausage, moa a me nā huahana moa a me ka ?ai a me nā huahana marinade.
