The Science Behind America's Favorite Snack
Tingave tisingazivi nguva dzose kuti chii chinokonzera popcorn pop, asi vanhu vave vachifarira popcorn kwezviuru zvemakore . Zviitiko zvinonzi magic popcorn kune zvidhori zviduku zvakaputirwa mukati mekernel iyo yaizoputika nehasha apo inopisa, asi isu zvino tinoziva kuti chikonzero chaicho chikonzero nei popcorn pops inosanganiswa kusanganiswa kwemakemikari uye physics.
The Kernel - Kunyatsoongorora
Kuti unzwisise kuti nei kernel yemapipcorn inoputika apo inopisa, tinofanira kutanga tanzwisisa kuvaka nokugadzirwa kwegorosi kernel.
Iko rekunze, rhenje, ruvara, ruvara rwegorosi ndicho chakavanzika chokupura zviyo. Kana yakanyatsogadzikana, hovha yacho haina kukonzerwa nekunyorovesa uye chinhu chinoita kuti kuve nekudzvinyirirwa kunoda kuparadzira chibage.
Mukati mekona ndiyo endosperm. Iyo endosperm inosanganisira yakasimba starch uye shoma shoma (inenge 14%). Sezvo ani zvake akachera mu kernel isati yambozivikanwa anoziva, isati yasvika nzvimbo ye starchy idombo rakaoma.
The Perfect Pop
Apo kernel inopisa, huwandu hunyoro hunovhara mu kernel huchienda kune mhepo, iyo inodzingwa pane imwe nzvimbo yekubikira nenzvimbo yakamanikidzwa yakagadzirwa nehombe. Kupisa kunopisa gelatinizes the starch yakaoma, kuishandura kubva padombo rakasimba kusvika pane chimiro chisingatauriki.
Sezvo kernel ichiri kupisa, kupera kunopedzisira kwapfuura simba rehombe, panguva iyo hull rupture. Mhepo inomanikidzwa mukati memakernel inokurumidza kuwedzera uye inokonzera starch gelatinized kuti ikonze.
Sezvo simbi inopukunyuka, kutonhora kwema starch nokukurumidza kunodonha uye kunobvumira kuti zvakare zvakare kutora fomu yakasimba. Chigumisiro chacho chakakwana kwazvo, chinokonzera kernel.
Kupinda Makomba
Mumagetsi ose emapokota, pane nguva dzose maziso mashomanana asina kumbobhururuka kana kungoputika pasina kubuda. Pane zvikonzero zvakakonzerwa zvinokonzera, asi zvishomanana zvisingabatanidzi muhuwandu hwekugadzira zvinowanzokonzera.
Chikwata chinokanganisa ndicho chinonyanya kukosha chep-mis-pop. Kana hove yacho ichinyanya kudarika kana kuti yakanyengedzwa munzvimbo, kuoma hakuzoiti mukati memhara. Sezvo mhepo inopisa inopisa uye inoshanduka kuenda kumhepo, inonyura zvishoma nezvishoma kubva kernel. Izvi zvinogona kugara zvakanyatsogadzikana kana kuti zvinoparadzaniswa pamberi pemashizha gelatinizes, zvichiita kuti pave nekuzaruka asi yakagadzirwa kernel.
Mvura yakadzika inowanikwa mu kernel inokonzerawo kukanganisa kupera. Pasina steam yakakwana mu kernel, kupikisa hakugoni kuvaka uye starch haigoni kuwedzera gelatinize. Popcorn vashandi vanonyatsomesa chibage kuti zvibudirire mazinga ehuwandu hwakawanda hwomunyoro kuitira kuti zvive zvakanaka.
Kupisa kusina kunaka kunogona kukonzera kukundikana kupona. Chibage chinogadzirwa zvakanaka mumhepo inopisa yakabudiswa nemhepo kana mafuta. Iko rudzi rwekupisa kunopoteredza kernel uye inoipisa nenzira yakafanana uye nokukurumidza. Kunopisa zviyo zvishoma nezvishoma kana pane kutonhora kwakanyanya kuderera hakugoni kuisa kukwana kwakakwana mukati memwenje kuitira kuti ipinde. Kupisa zviyo zvisina kufanira kana kuti zvishoma nezvishoma zvinogona kuita kuti hove yacho iparuke panzvimbo imwe chete kernel yose isati yanyisa kuwedzera, ichisiya isina kuvhara uye pamwe inopisa kernel.
