ʻImi ʻepekemama ka hana ʻana, ka maikaʻi a me nā noi kūpono o nā kiʻiʻoniʻoni edible/biodegradable i ka hana ʻana i nā meaʻai i lawe ʻia e kekahi mau hui noiʻi ma ka honua holoʻokoʻa a ua hōʻike ʻia ma nā puke noiʻi.5-9.ʻO ka nui o ka pāʻoihana a me ke kaiapuni ma kahi o nā kiʻiʻoniʻoni hiki ke ʻai/biodegradable/coatings ua koʻikoʻi pinepine ʻia.5,10,11a ua nui nā puke i hoʻoponopono mua i nā pilikia e pili ana i nā waiwai mechanical, ka neʻe ʻana o ke kinoea, a me nā hopena o nā mea ʻē aʻe i kēia mau waiwai, e like me ke ʻano a me ka ʻike o nā plasticisers, pH, ka haʻahaʻa pili a me ka mahana etc.6, 8, 10-15.
Eia naʻe,noiʻi i nā kiʻiʻoniʻoni hiki ke ʻai/biodegradableaia nō i kona wā kamaliʻi a me ka noiʻi ʻana e pili ana i ka hoʻohana ʻana i nā kiʻi ʻoniʻoni ʻai/biodegradable i nā makahiki i hala iho nei, akā naʻe, ua kaupalena ʻia ka uhi.
ʻO nā mea noiʻi maka Hui Pūʻulu Meaʻai, Ke Keʻena ʻEpekema Meaʻai a Nutritional, University College Cork, ʻIlelani, ua hoʻomohala i nā kiʻiʻoniʻoni hana, biopolymer-based, edible/biodegradable i nā makahiki i hala.
ʻO nā palena o ka ʻeke ʻai
ʻO ka maʻamau, ua kaupalena ka hoʻohana ʻana o nā kiʻiʻoniʻoni edible ma muli o ko lākou ʻano kino kino.No ka laʻana, loaʻa i nā kiʻiʻoniʻoni hoʻokahi, lipid-based nā waiwai pale maʻamau akā ʻaʻohe ikaika mechanical23.No laila, ua hana ʻia nā kiʻiʻoniʻoni laminated ma o ka hoʻopili ʻana i ʻelua a ʻoi aku mau kiʻiʻoniʻoni biopolymer.Eia nō naʻe, ʻoi aku ka maikaʻi o nā kiʻiʻoniʻoni laminated i nā kiʻiʻoniʻoni biopolymer hoʻokahi, emulsion-based ma muli o ka loaʻa ʻana o nā waiwai pale i hoʻonui ʻia.Hiki i ka hana ʻana i nā hale laminated ke lanakila i kēia mau hemahema e ka ʻenekinia edible/biodegradable films me nā papa hana he nui.
ʻO nā kiʻiʻoniʻoni a me nā uhima muli o ka wai-soluble proteins he mau wai-soluble lākou iho akā loa'a iā lākou ka oxygen maika'i loa, lipid a me nā waiwai pale 'ono.Hana ʻia nā protein ma ke ʻano he cohesive, structural matrix i nā ʻōnaehana multicomponent, e hāʻawi ana i nā kiʻiʻoniʻoni a me nā uhi me nā waiwai mechanical maikaʻi.ʻO nā lipid, ma ka ʻaoʻao ʻē aʻe, ke hana nei ma ke ʻano he mau pale makū maikaʻi, akā loaʻa ka ʻino kinoea, lipid a me nā pale ʻono.Ma ka hoʻohui ʻana i nā protein a me nā lipids i ka emulsion a i ʻole bilayer (he membrane i loaʻa i ʻelua papa mole), hiki ke hoʻohui ʻia nā ʻano maikaʻi o nā mea ʻelua a hoʻemi ʻia nā mea maikaʻi ʻole.
Mai ka noiʻi i hana ʻia e kaHui Pūʻulu Meaʻaima UCC, ʻo nā hiʻohiʻona maʻamau o nā kiʻi ʻoniʻoni ʻai/biodegradable i kūkulu ʻia penei:
- ʻO ka mānoanoa o nā kiʻi ʻoniʻoni ʻai/biodegradable i hana ʻia mai 25μm a 140μm
- Hiki i nā kiʻiʻoniʻoni ke akaka, akaka, a me ka translucent a i ʻole ka opaque ma muli o nā mea i hoʻohana ʻia a me ke ʻano hana i hoʻohana ʻia
- ʻO nā ʻano kiʻiʻoniʻoni kūikawā ma lalo o nā kūlana kaiapuni i mālama ʻia i hoʻomaikaʻi i nā waiwai mechanical a me nā waiwai pale kinoea
- ʻO ka mālama ʻana i nā kiʻiʻoniʻoni ma ke kūlana ambient (18-23°C, 40-65 pākēneka RH) no ʻelima mau makahiki ʻaʻole ia i hoʻololi nui i nā ʻano hana.
- ʻO nā kiʻiʻoniʻoni i hana ʻia mai nā ʻano mea like ʻole hiki ke maʻalahi i ka laminated hui
- Hiki ke hōʻailona ʻia nā kiʻiʻoniʻoni i hana ʻia, paʻi ʻia a hoʻopaʻa ʻia paha
- ʻO nā ʻokoʻa liʻiliʻi o ka microstructure kiʻiʻoniʻoni (e laʻa me ka hoʻokaʻawale ʻana o ka biopolymer phase) pili i nā waiwai kiʻiʻoniʻoni
