M'miyezi yaposachedwa, nkhani zapadziko lonse lapansi zozungulira thiourea zakopa chidwi chachikulu, kuwonetsa kufunika kwake m'mafakitale osiyanasiyana. Thiourea, mankhwala okhala ndi sulfure, amagwiritsidwa ntchito makamaka popanga feteleza, mankhwala, komanso ngati reagent pakupanga mankhwala. Makhalidwe ake apadera amapangitsa kuti ikhale yosunthika, yofunikira pazinthu zambiri. Pamene dziko likulimbana ndi zovuta zaulimi wokhazikika, thiourea yatulukira ngati gawo lofunikira pakukulitsa zokolola. Udindo wake monga gwero la nayitrogeni mu feteleza ndi wofunikira, makamaka m'madera momwe nthaka ikucheperachepera. Malipoti aposachedwa...

Sodium bisulfite, mankhwala osunthika, yakhala ikufalitsa nkhani zapadziko lonse lapansi chifukwa chakugwiritsa ntchito mosiyanasiyana komanso kuchuluka kwa kufunikira m'mafakitale osiyanasiyana. Ufa woyera wa crystalline uwu, wokhala ndi mankhwala a NaHSO3, umagwiritsidwa ntchito makamaka ngati chosungira, antioxidant, ndi kuchepetsa wothandizira. Kufunika kwake kumachokera ku kusunga zakudya ndi zakumwa mpaka kuyeretsa madzi ndi kupanga nsalu. M'makampani azakudya, sodium bisulfite imagwiritsidwa ntchito nthawi zambiri pofuna kupewa browning mu zipatso ndi ndiwo zamasamba, kuwonetsetsa kuti zogulitsazo zimakhalabe zowoneka bwino komanso zopatsa thanzi. Kuphatikiza apo, imagwira ntchito yofunika kwambiri mu winemakin ...

Ma ammonium sulfate granules atuluka ngati gawo lofunikira kwambiri pazaulimi, akugwira ntchito ngati feteleza wa nayitrogeni wothandiza kwambiri yemwe amakulitsa chonde m'nthaka komanso zokolola. Pomwe kufunikira kwa chakudya padziko lonse lapansi kukukulirakulira, msika wa ammonium sulfate granules ukukulirakulira. Blog iyi imayang'ana pakuwunika kwa msika wapadziko lonse wa ammonium sulfate granules, ndikuwunikira zomwe zikuchitika, madalaivala, ndi zovuta. Msika wapadziko lonse wa ammonium sulfate granules umayendetsedwa makamaka ndi kufunikira kwa feteleza wapamwamba kwambiri kuti athandizire ulimi wokhazikika. Alimi akutembenukira ku ammonium sulphate d ...

Phosphoric acid, madzi opanda mtundu, opanda fungo, ndi mankhwala ofunikira omwe amagwiritsidwa ntchito m'mafakitale osiyanasiyana. Kapangidwe kake ka mankhwala, H₃PO₄, kumatanthawuza kupangidwa kwake kwa maatomu atatu a haidrojeni, atomu imodzi ya phosphorous, ndi maatomu anayi a okosijeni. Mankhwalawa ndi ofunika kwambiri popanga feteleza komanso amathandiza kwambiri pokonza zakudya, kupanga mankhwala, ngakhalenso kuyeretsa. Muulimi, phosphoric acid imagwiritsidwa ntchito makamaka popanga feteleza wa phosphate, womwe ndi wofunikira kwambiri pakukulitsa chonde komanso kulimbikitsa kukula kwa mbewu. Fetelezawa amapereka zakudya zofunikira zomwe zimathandiza kuti ...

Sodium metabisulfite, mankhwala osunthika, akhala akuchulukirachulukira pamsika wapadziko lonse lapansi chifukwa chogwiritsa ntchito mosiyanasiyana m'mafakitale osiyanasiyana. Pagululi, lomwe limagwiritsidwa ntchito ngati chosungira, antioxidant, ndi bleaching agent, ndi lofunikira pakukonza chakudya, mankhwala, ndi chithandizo chamadzi, pakati pa magawo ena. Zomwe zachitika posachedwa zikuwonetsa kukula kwa msika wa sodium metabisulfite. Malinga ndi malipoti amakampani, kufunikira kwa sodium metabisulfite kukuyembekezeka kukwera pang'onopang'ono, motsogozedwa ndi kufunikira kowonjezereka kosunga chakudya komanso chitetezo. Pamene ogula akuyamba kuganizira za thanzi, f ...
