Sodium nitrite (colloquial, kom raug - sodium nitrate lossis sodium nitrite) yog siv hauv kev lag luam ua zaub mov ntxiv (raws li kev khaws cia). Nws muaj cov nyhuv carcinogenic (raws li qee cov neeg sawv cev ntawm cov tshuaj, nws tuaj yeem ua rau mob qog noj ntshav). Sodium nitrite nyob rau hauv hnyuv ntxwm thiab lwm yam (feem ntau yog nqaij) cov khoom yog hu ua E-250.

Cov tshuaj tiv thaiv ntawm hom no muaj qhov ntsuas ntawm E-200 txog E-229. Lawv tiv thaiv (lossis theej, txo qis) kev tsim tawm ntawm fungi thiab ntau yam kab mob. Cov tshuaj yog siv tsis tau tsuas yog nyob rau hauv cov nqaij cov khoom, tab sis kuj nyob rau hauv winemaking - raws li ib tug txhais tau tias ntawm kev txwv tsis pub lub maturation ntawm cawu cub (tshuaj tua kab mob).

Sodium nitrite yog crystalline (los ntawm lub teeb daj mus rau dawb) hmoov. Hygroscopic, zoo heev soluble hauv dej. Thaum raug cov pa oxygen (tsis yog hermetically kaw) maj mam oxidizes rau NaNO3 (sodium nitrate). Ib tug muaj zog heev txo tus neeg sawv cev. Toxic.

Raws li kev tshawb fawb, nws muab tawm: sodium nitrite,interacting nrog amino acids, thaum rhuab, nws muab ib tug carcinogen uas yuav provoke kev loj hlob ntawm cov qog nqaij hlav, incl. mob qog nqaij hlav hauv plab thiab obstructive pulmonary disease.

Vim li cas, txaus ntshai heev, yog sodium nitrite muaj nyob rau hauv cov khoom nkag mus rau hauv khw thiab khw muag khoom? Hauv kev lag luam, nws yog siv rau cov laj thawj hauv qab no:

- ua cov tshuaj tiv thaiv kab mob uas muab cov xim "natural" rau nqaij thiab ntses;

- hloov hom kev ua noj (tsis yog 100 ° C, kev ua haujlwm ntawm 72 ° C yuav txaus - kev txuag nyiaj yog impressive); - raws li cov tshuaj tua kab mob tiv thaiv Clostridium botulinum (tus neeg sawv cev ntawm botulism). Los ntawm txoj kev, tom kawg dhau los ua tus neeg ua txhaum ntawm kev qaug cawv hnyav, ua rau muaj kev puas tsuaj rau lub paj hlwb.

Qhov tsis muaj cov khoom ntxiv yuav ua rau cov khoom tsis zoo ntxoov ntxoo los ntawm ntsuab mus rau xim av-grey - xim uas tsis pom tseeb. Los ntawm "kev zoo nkauj", tsis yog txhua tus yuav xav txiav, thiab ntau ntxiv p

ua rau qhua. Txawm li cas los xij, txawm tias qhov no tsis yog qhov tseem ceeb. Tsis muaj lwm yam tshuaj ntawm no tuaj yeem tiv thaiv kev loj hlob ntawm cov kab mob phem. Nws hloov tawm tias tam sim no nws tsis tuaj yeem ua yam tsis muaj E-250. Yuav ua li cas? Ua noj ntawm koj tus kheej! Yam koj ua koj tus kheej yuav yog qhov tshiab thiab tiag tiag tsis muaj additives. Thiab cov chaw tsim khoom lag luam delicacies tuaj yeem pampered tsuas yog qee zaus thiab qis qis. Hauv qhov no, koj tsis tas yuav txhawj xeeb txog sodium nitrite ua teeb meem rau koj txoj kev noj qab haus huv.

Sodium nitrite (GOST 19906-74, m OSCH 4-7-3)ntxiv rau pob zeb thiab cov qauv ua ib qho inhibitor ntawm AK (atmospheric corrosion); siv nyob rau hauv cov organic synthesis; nyob rau hauv kev thov nyob rau hauv lub pulp thiab ntawv, metallurgical, kev kho mob, tshuaj industries.

NaNO2 yog tam sim no nyob rau hauv diazo dyes, siv nyob rau hauv dyeing tej yam ntuj tso fabrics (xws li bleached sawv daws yuav), nyob rau hauv zus tau tej cov roj hmab, nyob rau hauv phosphating (nyob rau hauv metalworking), thiab tshem tawm tin. Cov kws yees duab uas siv cov tshuaj tua kab mob antioxidant thaum tsim cov duab tau paub txog nws. Nrog rau txoj hauv kev tsim nyog, sodium nitrite dhau los ua ib qho tshuaj zoo heev uas txo cov plab hnyuv, ua kom lub bronchi (vasodilator, bronchodilator), ua cov tshuaj laxative thiab tib lub sijhawm yog tshuaj tua kab mob rau cyanide lom..
