Iyo pangasius inoramba iri protagonist yezvidzidzo zvesainzi zvinokurudzira kudzivirira kushandiswa kwayo. Kwemakore mashoma, masupamaketi akamira kuitengesa, misha yevakwegura haibiki uye macanteen echikoro haaisire vana.
Vamwe vanhu havasati vaona kuti sei kushandisa kwavo kuri kudonha, saka tinokuudza nezve ongororo yakaitwa neYunivhesiti yeLa Laguna (Tenerife). Yakanga iri World Health Organisation iyo yakatanga kuisa yambiro pamusoro pehuwandu hwayo hwesimbi dzakadai semercury.
Mutengo wayo wakachipa, kupfava kunyoro, uye kusimba, kunyorova kwemavara kunoita kuti ive yakakurumbira pasi rese. Nekudaro, inogona kuunza njodzi yakanyanya yechepfu yechikafu, saka isu tinofanirwa kuve nechokwadi chekuibika nemazvo.
Ihove rudzii inonzi pangasius?
Pasina mubvunzo, pangasius ndeimwe yehove dzinodyiwa zvakanyanya munyika, asi maererano neEuropean mercury levels, haienderani nemitemo. Ihove yerudzi rweVietnamese, kunyanya kubva kuRwizi rweMekong, inova imwe yeakareba pasi rose uye zvakare imwe yeakanyanya kusvibiswa.
Iyo inozivikanwa zvakare sebasa, uye imhando yekatfish yemhuri yePangasiidae. Zita rayo repamutemo resainzi ndiPangasius bocourti. Tinogona kunge takanzwawo hove dzebasa dzinonzi rwizi, Vietnamese cobbler, pangasius, kana swai.
Nyama yayo ine chiedza chakajeka, chakasimba uye ine hove yakapfava inonaka, yakafanana nekodha kana hake. Muchokwadi, dzimwe nguva inotengeswa sehove isina mapfupa uye inoshandiswa nenzira imwecheteyo. Hove dzePanga dzinowanikwa kunzizi dzeMekong neChao Phraya, dzinoyerera nenyika dzinoverengeka muSoutheast Asia.
Nekuda kwemukurumbira wavo uye kudiwa kwakanyanya kunze kwenyika, vanokwidziridzwawo muhuwandu mumapeni akatenderedza Rwizi rweMekong. Ichi ndicho chimwe chezvikonzero nei ichizivikanwa zvakanyanya nekuda kwemutengo wayo. Kuuchika kwakachipa, saka tinokwikwidzwa mitengo, kunyangwe tichitengeswa kunze kwenyika.
Njodzi dzinogona kuitika dzekushandisa kwayo
Vatsvagiri kubva kuYunivhesiti yeLa Laguna vanga vachifarira kuongorora njodzi ine chepfu ye mercury iyo inogona kubatsira kushandiswa kwepangasius. Nokuda kweizvi, vakaongorora 80 samples yemafuta akaomeswa nechando, ayo akachengetwa mumahypermarket matatu akasiyana uye ayo anogona kutora vatengi vekupedzisira mune marinade kana zvakasikwa.
Zvave zvichiratidzwa kuti pangasius mune marinade inodarika iyo yakanyanya kuwanda inobvumirwa nemutemo weEurope pa 0 mg / kg. «Kana aya data awanikwa uye achitora kudyiwa kwevhiki nevhiki kwe350 magiramu epangasius, chikamu chemupiro kuTolerable Weekly Intake (WIT) yemercury i32 muzana uye 27,5 muzana yevakadzi nevarume, zvichiteerana.«, akadaro Ángel J. Gutierrez, purofesa akachengetwa weToxicology Area yeYunivhesiti yeLa Laguna.
Kazhinji, kudya chero rudzi rwehove kune dzimwe njodzi. Izvi zvinodaro nekuti hove dzinogona kunge dziine zvinosvibisa kubva mumarara emumaindasitiri senge mercury uye polychlorinated biphenyls. Mishonga iyi inogona kuungana mumuviri uye ine chepfu. Zvisinei, kune vanhu vanotenda kuti kubatsira kwekudya hove kunopfuura chero njodzi dzinogona kuitika.
Zvimwe zvidzidzo zvakawana heavy metal residues mupangasius kuva mukati memiganhu yakachengeteka. Zvisinei, zvave zvichinzi nzira inokwidziridzwa nayo hove uye nharaunda yadzinogara inogona kuita kuti mhuka iyi ive chikafu chine njodzi huru. Madziva ayo anokwidziridzwa anogona kusvibiswa. Kudzora izvi, varimi vehove vanofanira kushandisa mishonga nemishonga kudzora utachiona uye utachiona; zvikamu izvi zvinogona kukanganisa hove.
Zvimwe zvidzidzo zvakawana kuti pangasius inotengeswa kubva kuVietnam haizadzise mitemo yekuchengetedzwa kwenyika. Muchokwadi, hove idzi dzinogona kunge dziine huwandu hwemishonga yemhuka, kusanganisira mishonga inorwisa mabhakitiriya, muhuwandu hunopfuura miganhu yemutemo.
Imwe ongororo yakaratidzawo kuti 70-80% ye pangasius yakatumirwa kunyika dzeEurope yakasvibiswa neVibrio mabhakitiriya, chikonzero chinowanzokonzera chepfu yezvokudya. Kuti uderedze njodzi yekudya muchetura, iva nechokwadi chekubika basa nemazvo uye usaidya iri mbishi kana isina kubikwa.
Kuderera kwekudya kunovaka muviri
Dzimwe nyanzvi dzechikafu dzinoti kudya pangasius svondo rega-rega hakuzokonzeri dambudziko reutano, kana toreva nezvemercury. Kune hove dzakadai tuna, swordfish kana shark Vane mazinga akakwirira emercury kupfuura pangasius, asi kukosha kwavo kwekudya kwakakwirira zvikuru.
Kungofanana nemamwe marudzi ehove chena, pangasius yakaderera mumakori uye yakapfuma muprotein yepamusoro. Chikamu che 126 gramu chinopa:
- Simba: 158 macalorie
- Mapuroteni: 22,5 gramu
- Mafuta: 7 gramu
- Mafuta akazara: 2 gramu
- Cholesterol: 73 mg
- Carbohydrates: 0 gramu
- Sodium: 89 mg
Nekuda kweiyo yakaderera calorie uye yakakwira mapuroteni, inogona kuve chikafu chinobatsira chedieters, semamwe marudzi ehove chena. Iinewo magiramu mashanu emafuta asina unsaturated, kusanganisira mamwe Omega-5 fatty acids. Omega-3 fatty acids akakosha mafuta akakosha kuchengetedza hutano hwakanyanya hwemuviri uye hwehuropi, kunyanya paunenge uchikura. Nekudaro, iyo panga haina yakawanda yemafuta aya, saka inova shoma inokurudzirwa.
The Spanish Agency for Consumption, Food Safety and Nutrition inokurudzira kudzivisa pangasius uye kubheja pane dzimwe hove dzakagadzikana, dzinopa mapuroteni akawanda nemafuta ane utano uye, pamusoro pezvose, kuva nekunaka kuri nani.
Kunyangwe iri hove dzakachipa dzisina boneless, zvingava nani kuti vana vedu vajaidze mazamu avo kune mamwe marudzi ezvinonaka. Kunyange zvakadaro, hatifaniri kurega kuitora nokuda kwesimbi yayo, kana zviri izvo zvinotinetsa.
