Ko te rangahau mō ngā kai kēne ngohengohe kei te ārahihia e te Hononga o Amerika, mai i te tau 1940. I te tau 1956, i whakamātauhia a Nelson rāua ko Seinberg o Illinois ki te whakamātautau i ētahi kiriata tae atu ki te kiriata polyester. Mai i te tau 1958, kua tīmata te US Army Natick Institute me te SWIFT Institute ki te ako i tētahi kai kēne ngohengohe mō te ope taua hei whakamahi, kia taea ai te whakamahi i te putea koromamao hei utu mō te kai kēne pereti tine i te papa pakanga, he maha ngā whakamātautau me ngā whakamātautau mahi. Ko ngā kai kēne ngohengohe i hangaia e te Natick Institute i te tau 1969 i whakawhirinakihia, ā, i whakamahia angitu ki te Apollo Aerospace Program.
I te tau 1968, i whakamahia e te Japanese Otsuka Food Industry Co., Ltd. he hua kari mārama, he putea retort pāmahana teitei, ā, kua eke ki te hokohoko i Hapani. I te tau 1969, i hurihia te pepa konumohe hei rauemi mata hei whakanui ake i te kounga o te putea, kia haere tonu ai te horapa o ngā hokonga mākete; i te tau 1970, ka tīmata te whakaputa hua raihi kua takaihia ki ngā putea retort; i te tau 1972, i whakawhanakehia te putea retort, ā, i hokohokohia hoki te taonga, arā, ngā mītiporo kua takaihia ki te putea retort ki te mākete.
I te tuatahi, i hangaia te putea retort momo pepa konumohe ki ngā paparanga e toru o ngā rauemi ātete wera, e kiia nei ko te "pukoro retort" (RP te poto), he putea retort i hokona e te Kamupene Can Toyo o Hapani, kei roto ko te pepa konumohe e kiia nei ko te RP-F (ātete ki te 135°C), ko ngā putea hiato papa maha mārama kāore he pepa konumohe e kiia nei ko te RP-T, RR-N (ātete ki te 120°C). Ka karangahia tēnei putea e ngā whenua o Ūropi me Amerika he kēne ngāwari (Kēne Ngāwari, Kēne Ngāwari rānei).

2. He tata ki te kore te uruhanga hāora me te uruhanga makuku, ā, e kore rawa e taea te whakarerekē matū i ngā ihirangi, ā, ka taea te pupuri i te kounga o ngā ihirangi mō te wā roa.
3. Ka taea te whakamahi i te hangarau whakaputa me ngā taputapu o ngā kai kēne i roto i ngā kēne whakarewa me ngā pounamu karāhe.
4. He pono, he ngāwari hoki te hiri.
5. Ka taea te hiri wera i te putea, ā, ka taea hoki te poka ki ngā kōhao āhua-V me te āhua-U, he ngāwari ki te haehae me te kai mā te ringa.
