Natural yoghurt inoonekwa nevakawanda sechigadzirwa chechisikigo. Nekudaro, kazhinji haisi iyo chete yekutanga zvinongedzo mukaka uye lactic acid mabhakitiriya anoshandiswa mukugadzira asiwo zvinowedzera zvakaita semukaka upfu. Kune zvakare misiyano mikuru mukuravira uye kuenderana kweyoga yega yega.
Yogurt: kugadzirwa uye zvigadzirwa
Lactic acid mabhakitiriya akakosha pakugadzirwa kweyoghurt: Kana ukaawedzera kumukaka uye ukaramba uchidziya zvakakwana, mabhakitiriya anoshandura shuga yemukaka (lactose) kuita lactic acid (lactate). Izvi zvinodzikisa kukosha kwepH mumukaka: mapuroteni anobatana, uye yoghurt inogadzirwa. Lactic acid inochengetedza yakasikwa inopa iyo yogati hupenyu hurefu hwesherufu. Nhamba yemukaka yakadhindwa pa yoghurt inogona kushandiswa kuona kuti ndeipi kambani yakagadzira iyo: nhamba imwe neimwe inogoverwa kune iyo inonzi dairy product company.
Utachiona hunoshandiswa hune pesvedzero pakuravira kweyoga yega yega. Iwe unosarudza kuti yoghurt inonaka zvakapfava here kana kuvava. Mhando dzemhando dzakatsanangurwa muMilk Products Ordinance: Semuyenzaniso, yoghuti “yakapfava” haifanire kunge ine utachiona hweLactobacillus bulgaricus asi inofanira kugadzirwa kubva kuutachiona hweyogati hunovava zvishoma.
Hupfu hwemukaka hunowedzera lactose content
Vanhu vane lactose kusashivirira vanowanzoshivirira yoghurt nekuti mabhakitiriya elactic acid anopwanya lactose zvachose. Nekudaro, kuwedzera hupfu hwemukaka kunowedzera shuga yemukaka (lactose) iri muyoghurt. Zvinoenderana neMilk Products Ordinance, kuwedzera kwehupfu hwemukaka hakufanirwe kuziviswa pane rondedzero yezvigadzirwa, sezvo hupfu hwemukaka hunoonekwa sechikamu chemukaka.
Genetic engineering mu yoghurt yechisikigo
Genetic engineering mune zvigadzirwa zvemukaka inyaya yakakosha kune vazhinji vatengi. Zvinonyanya kutaura nezvekudya kwemhou: kana mhuka dzakapihwa chikafu chakanyanya, izvo zvinowanzo shandiswa zviyo chibage, rapeseed meal uye soy zvinogona kubva kune genetically modified plants. Vazhinji vagadziri veiyo yoghurt yechisikigo vanozivisa zvigadzirwa zvavo nemashoko akadai se "pasina genetic engineering".
Hazvina kunyatsojekeswa nesainzi kana zvakagadziridzwa gene zvikamu zvechikafu zvinopedzisira zvave mumukaka. Pane zvidzidzo zvega zvakakwanisa kuona zvidimbu zvejeni kubva muchibage chakagadziridzwa uye soya mumasero emhuka uyewo mumukaka.
Mukaka poda uye genetic engineering mune yakasikwa yoghurt
Mumuenzaniso usina kurongeka, Markt akatenga yoghuti yechisikigo kubva kuna Ja! (Rewe), Milsani (Aldi), Milbona (Lidl), Alnatura, Landliebe uye Weihenstephan. Mutengo we500 gramu uri pakati pe0.45 ne1.29 euros.
Zvinoenderana nekutaura kwavo, Weihenstephan, Aldi, Lidl naLandliebe havawedzeri hupfu hwemukaka kune yavo yega yoghuti. Isu tinovimba nechakavanzika chekubika. Paakabvunzwa naMarkt, Alnatura akataura kuti yakawedzera skimmed mukaka poda kune yoghuti "kuchengetedza kuwirirana uye kudzivirira mvura kuti isagadzikane". Alnatura inotaura hupfu hwemukaka pane rondedzero yezvigadzirwa.
Pakukumbira kwemusika Aldi, Alnatura, Landliebe, Lidl naRewe vakazivisa kuti havana kushandisa genetic engineering muyogati yechisikigo. Weihenstephan haasati aita chirevo (kubva muna Gumiguru 19, 2018).
