Ngizibuza ukuthi kungani sesabeka kakhulu igama elithi "nitrate"? Esikhathini sesayensi, lezi zingamanzi ezingenalutho ezingenabungozi ze-nitric acid, izitshalo ezithatha emhlabathini njengezinto ezidingekayo eziphilayo. Imifino ngaphandle kwe-nitrate futhi isenzo sabo emzimbeni womuntu akakho nje. Inani libala! Uma lokhu kutholakala kakhulu emthini (ngenxa yokukhulelwa komhlabathi nge-nitrate), umane ubeka ngaphandle kwesitoko! Kodwa-ke, imbangela eyinhloko ye-poisoning nemifino yokuqala akuyona i-nitrates ngokwayo, kodwa i-nitrites eyakhiwe evela kubo emzimbeni. Ukungena egazini, kungabangela ukushona kwe-oksijeni, kuphazamise umsebenzi wegciwane lomzimba, ukwandise i-oncorrhiza, futhi ukusetshenziswa komthamo omkhulu we-nitrate kusongela ubuthi obubi. Yiqiniso, lezi zinkinga kungenzeka kuphela ekudleni kokudla kwe-nitrate njalo. Kodwa-ke, kunikezwa ukuthi cishe akunakwenzeka ukucacisa inani "chemistry" emifino noma izithelo ngeso, ukunakekelwa ngeke kuwuvimbele.
Ngendlela, isimiso esivumelekile nsuku zonke se-nitrate, ngokwezincomo ze-WHO, singama-3.7 mg nge-1 kg yesisindo somzimba.
Izimila ziyahlukahluka ekutheni zibuthe i-nitrate nemiphumela yazo emzimbeni womuntu: izinhlayiya eziphezulu (kufika ku-3000 mg) - imifino enamagatsha, ama-beet, ama-radishes namakhabe; Ephakathi (400-900 mg) - zucchini, ithanga, iklabishi, izaqathe, ukhukhamba; / phansi (50-100 mg) - izithelo, u-sorrel, amazambane, anyanisi, utamatisi, izithelo namajikijolo.
Irekhodi eliphelele lokuqukethwe kwe-nitrate (80% ngenhla evamile!) - isithombo sokuqala. Lokhu kubangelwa izindawo zayo ukudweba umswakama emhlabeni (kanye ne-nitrate).
Ngokujwayelekile imifino yokushisa ephezulu yokushisa yenziwa ngemifino yokushisa.
Khetha izithelo ezivuthiwe futhi uzilondoloze esiqandisini (ekamelweni lokushisa, ukuhlushwa kwe-nitrate ekudleni kwanda). Ngandlela-thile, ama-saladi ezenziwe ngemifino yokuqala, kuyinto efiselekayo yokusebenzisa i-baggy - iveza izitrodi ze-nitric acid ngenkuthalo.
Umsebenzi wesikole
Ngenhlanhla, kunezindlela eziningi zokunciphisa izinga lezingozi zemifino yokuqala ngaphandle kokushiya ikhishi lakho! Okokuqala, sidinga ukuqeda amaqabunga amabili noma amathathu aphezulu kanye nesitshalo - lapho, njengomthetho, i-chemistry iqoqa. Bese uhlanza isithelo kahle ngesibhamu (ungathola isisombululo soda: isipuni esingu-1 ilitha lamanzi, hlambulula evamile). Futhi uyihlanze ngokufanele: izaqathe namakhukhamba - unqunywe ezinhlangothini zombili ngo-1 cm, uthathe ama-radishes kusuka ku-radishes no-utamatisi. E-green and lettuce kufanele badle amaqabunga kuphela, hhayi iziqu (ziqoqa nitrate). Ungaphinda uphuze imifino ngaphambi kokusebenzisa isigamu sehora. Lokhu kuzosusa ama-nitrate angu-25-50%. Uma ukupheka okuqhubekayo kulandela, kuhlasela enye 25-50% ye "chemistry". Indlela ephumelela kakhulu - ukupheka: faka imifino ehlutshiwe emanzini ngaphandle kosawoti (usawoti - ekuphekeni kokupheka), upheke, bese uvula umhluzi. Ngendlela, lapho udoba, i-nitrate inikwe ingozi engasebenzi kahle kakhulu - kuphela ngo-10%. Kodwa omuncu, ngempela, owamukelekayo: eklabishi elungiselelwe ngale ndlela, kakade ngosuku lwesihlanu izinga le-nitrate linciphile ngesigamu.
Yiqiniso, kunezimpikiswano ngale ndlela - inani lamavithamini, i-alas, liyancishiswa kakhulu. Yini okufanele ngiyenze? Kunezinketho eziningana: ungakwazi ukubambezela ukuthenga "ezincane nasekuseni" (ezitsheni zomhlabathi ne-nitrate ngokuvamile kuvamile), ungakhula umkhiqizo we-eco (isaladi, u-anyanisi, imifino ebabayo) ekhaya efasiteleni, noma unciphise i-vitamin ukulahlekelwa neti elihlaza noma isiphuzo se-ascorbic. .. Ukuzikhethela kungokwakho!
Ayikho i-nitrate enesabekayo ...
Abanye ososayensi banombono wokuthi i-nitrate ngokulinganisa okulinganiselayo iyasiza emzimbeni wethu! Ngokuvamile umuntu ukhiqiza ngokuzimela kuze kube ngu-25-50% yalezi zinhlanganisela zamakhemikhali, konke okutholwa ngokudla. Futhi ziqukethe imikhiqizo yenyama, amanzi, ubhiya. Kakade emgodini womlomo ngaphansi kwethonya lama-nitrate ama-bacterium aguqulwa abe yi-nitrites, ngamathambo angena esiswini. Ngokwezibalo zabacwaningi baseSweden, akhiwa ama-nitrosamine amaningi kakhulu e-carcinogenic, ewusizo kumuntu we-nitrogen oxide (okwenza ngcono ukujikeleza kwegazi esiswini, ukuvikela isisu esiswini, izilonda nemiphumela yezidakamizwa ezinonya).
