Okuqukethwe
Kuyimpushana emhlophe, engenambitheki eyaziwa kwabaningi bethu. Itholakala kukolo nelayisi okusanhlamvu, ubhontshisi, i-tuber yamazambane, kanye nesikhwebu sombila. Kodwa-ke, ngaphezu kwale mikhiqizo, sithola isitashi kumasoseji abilisiwe, i-ketchup futhi, yiqiniso, kuzo zonke izinhlobo ze-jelly. Kuye ngemvelaphi yazo, izinhlamvu zesitashi ziyahlukahluka ngokuma nosayizi wezinhlayiyana. Lapho isitashi powder sikhama esandleni, sikhipha i-creak yesici.
Ukudla okunothe ngesitashi:
Kuboniswe inani elilinganiselwa ku-100 g womkhiqizo
Izici ezijwayelekile zesitashi
Isitashi asincibiliki ngokuphelele emanzini abandayo. Kodwa-ke, ngaphansi kwethonya lamanzi ashisayo, iyavuvukala iphenduke unamathisele. Ngenkathi sifunda esikoleni, safundiswa ukuthi uma uphonsa ithonsi le-iodine esicucwini sesinkwa, isinkwa sizoba luhlaza okwesibhakabhaka. Lokhu kungenxa yokuphendula okuthile kwesitashi. Lapho kukhona iodine, yakha okuthiwa i-blue amyliodine.
Ngendlela, ingxenye yokuqala yegama - "amyl", ikhombisa ukuthi isitashi siyinhlanganisela encane futhi iqukethe i-amylose ne-amylopectin. Ngokuphathelene nokwakhiwa kwesitashi, umsuka wayo uqhamuke kuma-chloroplast okusanhlamvu, kumazambane, kanye nasitshalweni esibizwa ngokuthi ummbila ezweni lakubo, eMexico, futhi sonke sisazi njengommbila.
Kumele kuqashelwe ukuthi, ngokwesakhiwo sayo samakhemikhali, isitashi yi-polysaccharide, okuthi, ngaphansi kwethonya lejusi lesisu, ikwazi ukuguqulwa ibe yi-glucose.
Imfuneko yesitashi yansuku zonke
Njengoba kushiwo ngenhla, ngaphansi kwethonya le-asidi, isitashi senziwa i-hydrolyzed bese siguqulwa sibe yi-glucose, okuwumthombo oyinhloko wamandla emizimbeni yethu. Ngakho-ke, ukuze uzizwe kahle, umuntu kufanele nakanjani adle inani elithile lesitashi.
Udinga nje ukuthi udle okusanhlamvu, ibhikawozi ne-pasta, imidumba (uphizi, ubhontshisi, udali), amazambane nommbila. Kuhle futhi ukufaka okungenani inani elincane le-bran ekudleni kwakho! Ngokwezibonakaliso zezokwelapha, isidingo somzimba sansuku zonke sesitashi singama-330-450 amagremu.
Isidingo sesitashi siyanda:
Njengoba isitashi siyi-carbohydrate eyinkimbinkimbi, ukusetshenziswa kwayo kufanelekile uma umuntu kufanele asebenze isikhathi eside, lapho kungekho khona ithuba lokudla njalo. Isitashi, esiguqula kancane kancane ngaphansi kwethonya lejusi yesisu, sikhipha ushukela odingekayo empilweni ephelele.
Isidingo sesitashi sinciphile:
- ngezifo ezahlukahlukene zesibindi ezihambisana nokuwohloka okungafanele kanye nokwenziwa kwama-carbohydrate;
- ngokuzikhandla okuphansi komzimba. Kulokhu, isitashi siyakwazi ukuguqulwa sibe ngamafutha, afakwa “pro-stock”
- esimweni somsebenzi odinga ukunikezwa kwamandla ngokushesha. Isitashi siguqulwa sibe ushukela kuphela ngemuva kwesikhathi esithile.
Ukugaya isitashi
Ngenxa yokuthi isitashi i-polysaccharide eyinkimbinkimbi, okuthi, ngaphansi kwethonya lama-acid, ingaguqulwa ngokuphelele ibe yi-glucose, ukugaya isitashi kulingana nokugaya kwe-glucose.
Izakhiwo eziwusizo zesitashi nomphumela waso emzimbeni
Njengoba isitashi sikwazi ukuguqula sibe yi-glucose, umphumela waso emzimbeni ufana noshukela. Ngenxa yokuthi imuncwa kancane kancane, umuzwa wokusutha kusuka ekusetshenzisweni kokudla okunesitashi uphakeme kunokusetshenziswa okuqondile kokudla okumnandi. Ngesikhathi esifanayo, umthwalo kuma-pancreas uncane kakhulu, onomthelela omuhle empilweni yomzimba.
Ukusebenzisana kwesitashi nezinye izinto ezibalulekile
Isitashi sihlangana kahle nezinto ezinjengamanzi afudumele nejusi esiswini. Kulokhu, amanzi enza izinhlamvu zesitashi zivuvuke, kuthi i-hydrochloric acid, eyingxenye yejusi lesisu, iyiphendule ibe ushukela omnandi.
Izimpawu zokushoda kwesitashi emzimbeni
- ubuthakathaka;
- ukukhathala;
- ukucindezeleka kaningi;
- amasosha omzimba aphansi;
- kwehle isifiso sobulili.
Izimpawu zesitashi esiningi emzimbeni:
- ikhanda elibuhlungu njalo;
- ukukhuluphala ngokweqile;
- amasosha omzimba aphansi;
- ukucasuka;
- izinkinga ezincane zamathumbu;
- ukuqunjelwa
Isitashi nempilo
Njenganoma iyiphi enye i-carbohydrate, isitashi kufanele silawulwe ngokuqinile. Ungadli izinto eziningi ngokweqile zesitashi, ngoba lokhu kungaholela ekwakhiweni kwamatshe endle. Kodwa-ke, akufanele ukugweme ukusetshenziswa kwesitashi noma, ngoba ngaphezu komthombo wamandla, yakha ifilimu evikelayo phakathi kodonga lwesisu kanye nejusi lesisu.
Siqoqe amaphuzu abaluleke kakhulu ngesitashi kulo mfanekiso futhi sizojabula uma wabelana ngesithombe kwinethiwekhi yokuxhumana noma kubhulogi, ngesixhumanisi saleli khasi:
