Uphizi oqandisiwe, ummbila oqandisiwe, i-broccoli eqandisiwe… Uma ungenaso isikhathi sokuthenga imifino njalo, ungase ufise ukugcina imifino eqandisiwe ekhaya, ngezinye izikhathi engazuzisi kangako kunemifino emisha.
Okokuqala, eminye imifino eqandisiwe ingase ibe nomsoco kunentsha.Ukulahleka kwezakhamzimba emifino kuqala kusukela ngesikhathi ikhiwa.Ngesikhathi sokuthutha nokudayiswa, amavithamini nama-antioxidants alahleka kancane.Kodwa-ke, uma imifino eqotshiwe iqandiswa ngokushesha, kufana nokumisa ukuphefumula kwayo, hhayi nje kuphela ukuthi ama-microorganisms angakwazi ukukhula futhi akhiqize, kodwa futhi ukuvala kangcono izakhi kanye nokusha.Ucwaningo luye lwabonisa ukuthi nakuba inqubo yokuqandisa esheshayo izolahlekelwa uvithamini C no-B oncibilika emanzini, umonakalo we-fiber yokudla, amaminerali, i-carotenoid, ne-vitamin E emifino awumkhulu, futhi amanye ama-antioxidants e-polyphenolic angase ande ekugcinweni.Isibonelo, ucwaningo lwaseBrithani lwathola ukuthi ngemva kokuqandisa, amavithamini nama-antioxidants anemiphumela yokulwa nomdlavuza ezithelweni eziningi nemifino evela ku-broccoli, izaqathe kuya kuma-blueberries cishe kuhle njengezithelo nemifino esanda kukhiwa, futhi kunomsoco kunezithelo nemifino eshiywe esitolo izinsuku ezingu-3.
Okwesibili, kulula ukupheka.Imifino efriziwe ayidingi ukugeza, ngokushesha i-blanched ngamanzi abilayo, ungapheka ngokuqondile, okuyinto elula kakhulu.Noma engeza ngokuqondile amanzi kuhhavini we-microwave ukuze incibilike, bese ugoqa-gazinga ebhodweni elilandelayo ukuze libe mnandi;Ungakwazi futhi ukuyifaka ngesitimu ngokuqondile bese uthela izinongo, futhi ukunambitheka nakho kuhle.Kumele kuqashelwe ukuthi imifino eqandisiwe ivame ukucutshungulwa kusuka emifino emisha ngesikhathi sonyaka, iqandiswe ngokushesha ngemuva kokushisa nokushisa, futhi igcinwe ku-18 ° C, ukuze ukwelashwa "kukhiye" umbala ogqamile wemifino ngokwawo, ngakho-ke asikho isidingo sokusebenzisa imibala.
Okwesithathu, isikhathi eside sokulondoloza.I-oksijeni ingakhipha i-oxidize futhi yonakalise izingxenye eziningi zokudla, njenge-pigment oxidation yemvelo izoba buthuntu, amavithamini namakhemikhali e-phytochemicals nezinye izakhi zifakwe i-oxidized ukuze kubangele ukulahlekelwa izakhi.Kodwa-ke, ngaphansi kwezimo ezibandayo, izinga le-oxidation lizoncishiswa kakhulu, inqobo nje uma uphawu luqinile, imifino efriziwe ngokuvamile ingagcinwa izinyanga noma ngisho nangaphezulu konyaka.Kodwa-ke, lapho ugcina, kufanele kuqashelwe ukuthi umoya kufanele uphele ngangokunokwenzeka ukuze imifino isondele esikhwameni sokudla ukuze igweme ukuphelelwa amandla kwamanzi kanye nokunambitha okubi.
