Nokuba yeyencasa okanye yeyokomeleza amandla, ikofu ibe yeyona nto ibalulekileyo kubomi bemihla ngemihla babantu. Ngenxa yoko, ngoku kukho iimveliso zekofu ezahlukeneyo kwimarike, ezinokuthi zohlulwe zibe ziindidi ezintathu eziphambili: ikofu ekhawulezileyo, ukugalela ngaphezulu, kunye nomhlaba omtsha. Icandelo ngalinye libonelela abathengi abahlukeneyo, ngoko ke ukhetha njani ikofu efanelekileyo kuwe? Funda ukuze ufumane ukuqonda okusisiseko.
Okokuqala, kubalulekile ukuqonda inkqubo yokuvelisa ikofu, yindlela ekhutshwa ngayo ikofu:
Ngoku ukuba iinkcukacha zenkqubo zicacile, makhe sicazulule iintlobo ezahlukeneyo zekofu:
Ikofu ekhawulezileyo
Ikofu ekhawulezileyo inembali ende, eyaqala ngo-1890. Yaqala ke imveliso eninzi ukusombulula intsalela yembotyi yekofu ngelo xesha. Le mveliso yomisiweyo yesitshizi yamkelwa kakuhle ngenxa yobukhulu bayo obuncinci, ukuhanjiswa lula xa ifika kwimarike. Ngoko nangoko ayifuni amanyathelo ongezelelweyo ngaphaya kokuxutywa ngokuthe ngqo namanzi, okwenza kube lula ngakumbi kunokugalela ngaphezulu.
Inkqubo yokuvelisa ibandakanya ukugaya iimbotyi ezigcadiweyo emva koko kukhutshwe amacandelo abalulekileyo emanzini phantsi kobushushu obumiselweyo kunye noxinzelelo. Ukutshiza ukomisa kubumba umgubo wekofu okhawulezileyo, onempembelelo enkulu kumgangatho. Uninzi lusebenzisa ukomisa isitshizi ngoku, kodwa izinto ezinevumba elimnandi zekofu zinokuguquka ngokulula phantsi kobushushu obuphezulu, zibangele ilahleko enkulu yencasa. Ngokusebenza ngokuphindaphindiweyo kobushushu obuphezulu, phantse akukho vumba lihlalayo, yiyo loo nto kwangoko kungabikho ivumba elimnandi lomhlaba omtsha.
Nangona kunjalo, ivumba lekofu sesona sizathu siphambili sokuba abantu bayonwabele ikofu namhlanje. Ke abavelisi bahlawula njani? Ngencasa eyenziweyo. Iibrendi ezahlukeneyo zongeza ii-agent zokunambitha (ezohlukeneyo kwiinkampani) ngexesha lokutsalwa, ukugxila, okanye ukomisa. Ngapha koko, iimbotyi zekofu ezisisiseko kwezona zininzi zekofu ekhawulezileyo lelona bakala lisezantsi kakhulu, liphantsi kakhulu ukuba lingathengiswa njengeembotyi ezizimeleyo. Isebenziseka kuphela ngoko nangoko.
Nangona kunjalo, ngenxa ye-R&D eqhubekayo, ubuchule obutsha obufana "nobushushu obuphantsi bokumisa umkhenkce" bunokufezekisa izibonelelo ezifana ne-0 trans fat. Ngokucocwa kwevacuum kunye nokukhenkceza okutsalweyo, iimbotyi zomhlaba, zigcina ngcono ivumba lokuqala xa lithelekiswa nokonakalisa ubushushu obuphezulu, zisondeza imveliso yokugqibela kwivumba lendalo lekofu.
Ukuqonda inkqubo yemveliso kwenza kucace ukuba ikofu ekhawulezileyo iqulethe iimbotyi zekofu ezicocekileyo njengesithako esikrwada. Nangona kunjalo, ezinye iintlobo zevenkile eziqhelekileyo zongeza izithako ezifana ne-creamer, amafutha emifuno, iswekile emhlophe - ezi ayizizo ikofu yokwenyani, kodwa "iziselo eziqinileyo zekofu." Ngokucacileyo, i-trans fats kwi-creamers kunye namafutha emifuno abeka ingozi yempilo enokuthi ikhulise amathuba okuba nesifo senhliziyo kunye nesifo seswekile.
Iingcebiso: funda ngononophelo ileyibhile xa uthenga ikofu ekhawulezileyo. Ukuba uluhlu lwezithako luqulethe iimbotyi zekofu kuphela, ngoko kukhuselekile ukuthenga.
Galela Phezu kweKofu
Eyenziwe ngamaJapan, galela ikofu ihambisa ikofu esandul' ukugatywa ngoko nangoko. Ibizwa ngokuba “yikofu evuzayo” ngesiJapan, isebenza ngokuqulatha ikofu yangaphambili kwisingxobo sokucoca ngelaphu elingalukwanga okanye iphepha lomqhaphu. Amaphepha amabini "iindlebe" ngapha nangapha afake phezu kwekomityi. Emva kokugalela amanzi ashushu, susa nje isingxobo kwaye wonwabele ikofu egcwele umzimba. Enkosi ngokuphatheka lula kunye nolungiselelo olulula olukhokelela kwincasa eyiyo, etyebileyo ngakumbi kunoko nangoko, ukugalela ngaphezulu kuphumelele uninzi lwabathandi bekofu ukusukela oko yaqalayo.
Oko kuthetha, ukhetha ukugalela ngaphezulukuthatha i-savvy:
1.Khangela umhla wemveliso. Ekubeni ukugalela ngaphezulu kusetyenziswa iimbotyi ezisandula ukugatywa, incasa iyancipha ngokuthe ngcembe ngokuhamba kwexesha. Ke inefestile yokungcamla eyona ilungileyo - iiveki ezi-2 ngokubanzi ukusuka kwimveliso.
2.Vavanya indlela yogcino. Ezinye iimveliso zitofa igesi yenitrogen ecothayo ukucothisa ilahleko yencasa, ukwandisa incasa yencasa ukusuka kwiiveki ezi-2 ukuya kwinyanga enye. Ukupakishwa kwefoyile yealuminiyam etyebileyo nako kugcinwe ngcono xa kuthelekiswa nephepha.
3.Qaphela imvelaphi. Njengewayini, iimbotyi zimisela incasa yokugqibela. Imimandla yekofu iquka iSumatra, iGuatemala, iYunnan.
4.Qwalasela indlela yokucubungula. Emva kokuvuna, iimbotyi zifuna ukususwa kwenyama ngaphambi kokuba zibe ziimbotyi zokwenyani. Uninzi lweendlela eziqhelekileyo "zomisiwe ngelanga" kunye "nokuhlanjwa kwamanzi." Ukomiswa ngelanga kudla ngokugcina incasa eninzi, ngelixa ukuhlanjwa kwamanzi kucocekile. Yamkela ukhetho lomntu.
Ikofu esandul 'umhlaba
Umhlaba omtsha uthetha ukugaya iimbotyi ezigcadiweyo zibe yimihlaba kanye phambi kokuba kwenziwe ibhiya ukuze kunyuswe ukutsha kunye nevumba elimnandi. Ngaphandle komgangatho wembotyi ngokwawo, ubungakanani bokusila yeyona nto iphezulu ephembelela ikofu elungileyo. Imihlaba enobungakanani obufanelekileyo ifanele isixhobo sokwenza ikofu enkulu. Ngamanye amagama, uburhabaxa buxhomekeke kwizinto ezikhethwayo kunye nezixhobo - hayi ezicolekileyo okanye ezicolekileyo.
Ngokwenyani, nokuba ungqiyame ngokungxama kwekofu ekhawulezileyo, ubuhle bokugalelwa ngaphezulu, okanye ubutsha obungenakuthelekiswa nanto bokusila iimbotyi zakho, isitshixo kukulungelelanisa ukhetho lwakho kunye nempilo yakho kunye nokuzonwabisa okukhethayo. Ikofu ayisosiselo nje; luhambo lwencasa ezilindele ukuphononongwa. Utywala olumnandi!
