Amerika y'Epfo ifite umutungo mwinshi w'ubuhinzi n'ubworozi, kandi inzira yayo yo gutera imbere mu nganda ikomeje kwiyongera. Ibicuruzwa bya Nonylphenol Ethoxylate (NPE) bigira uruhare runini mu kongera imikorere myiza y'umutungo n'ubwiza bw'umusaruro bitewe n'uburyo bwiza bwo kwinjira, gukwirakwiza, no gukwirakwiza, cyane cyane mu nzego ebyiri zisanzwe ariko z'ingenzi zikurikira:

1. Ubuhinzi bw'Amazi mu Nganda no Kubungabunga Imiyoboro

Shili, Peru, na Ekwateri bifite inganda nini z’ubworozi bw’amafi ya salmon na shrimp. Mu bworozi bw’amafi bukoresha imbunda zifunguye, imbunda zikunze kwibasirwa cyane n’ibimera bikomoka ku myanda, ibinyamisogwe n’ibindi binyabuzima. Ibi bibangamira cyane ihererekanya ry’amazi, byongera uburemere n’ibyago byo kwangirika kw’amafi, kandi bigira ingaruka ku buzima bw’amafi.

● Igice cy'ingenzi cy'ibikoresho byo gusukura imbunda bikoresha ikoranabuhanga rigezweho:Imiti yihariye isukura ikoresha NPEs nk'umusemburo w'ibanze ishobora gukuraho neza imyanda ikomeye iterwa no kwinjira no gukuraho. Gukoresha kwayo bigabanya cyane ingendo zo gusukura, bigabanya akazi n'ingufu, bigatuma umwuka wa ogisijeni ushonga mu mazi yo mu bwoko bwa cultured, kandi ni inkunga y'ingenzi mu bijyanye no kubungabunga imikorere myiza mu bworozi bw'amafi bukorerwa mu nganda nyinshi.

●Emulsifier y'inyongera ku mavuta yo kugaburira:Mu gukora ibiryo byo mu mazi birimo amavuta menshi, kongeramo ingano nto y’ibi biryo bituma amavuta avanganywa n’izindi ntungamubiri, bikongera ubushobozi bwo kugumana ibiryo no kuryoha, kandi bigatera imbere amatungo yorororwa.

2. "Moteri yo kwinjira" mu gutunganya uruhu

Arijantine, Urugayi na Brezili bizwi ku isi yose kubera uruhu rwabo rwiza cyane. Mu rugendo rugoye rwo guhindura uruhu rusanzwe ruba uruhu rwarangiye, imiti nk'iy'ibara ry'uruhu, amarangi, n'ibinure bigomba kwinjira mu buryo bwimbitse kandi bungana mu migozi ya kolajeni y'uruhu.

● Uburyo bwiza bwo kwiyuhagira no gusiga ibara ry'uruhu:Mu ntambwe za mbere nko kubyimbisha no gushyiramo ifu, NPE zitose vuba kandi zikinjira mu ruhu rwumye rufite umunyu, zigakuraho poroteyine zitari fibre hanyuma zigafungura inzira zo kuvurwa nyuma. Mu ntambwe nyamukuru zo gutwikira no kongera gutwikira, zikora nk'izinjira mu ruhu, zigatuma tannins za chrome, tannins za sintetike, n'ibindi, zifatanye n'imigozi y'uruhu. Ibi bigabanya igihe cyo gukora, bikongera imiterere y'uruhu, kandi bigatanga uruhu rwuzuye kandi rworoshye.

●Gupima no Gukwirakwiza Irangi n'Ibirungo:Mu gusiga amarangi no kuyasiga amavuta, bifasha gukwirakwiza amarangi n'amavuta mu bwogero bwo kuvurirwamo mu buryo bumwe kandi bigatuma yinjira mu ruhu, bigatuma uruhu rurangira neza kandi rukagira ibara rihoraho, bityo rugahuza n'ibisabwa ku buziranenge bw'ibicuruzwa by'uruhu byo mu rwego rwo hejuru.
