Kubonakala sengathi iwayini elibhekene newayini lingase libe nezinzuzo ezithile zezempilo , kodwa kunzima ukwazi ngokuqinisekile ngoba izifundo eziningi zenziwa ngewayini elivamile.
Iwayini elidayiswa ngamafutha liwayini elivamile nje eliye lasuswa cishe lonke utshwala. Kungase kube nesamba esincane esisele, kodwa singaphansi kwesigamu sephesenti esisodwa ngevolumu - encane ngokwanele ukuba ibhalwe ngokusemthethweni ngokuthi 'ukungenwa utshwala.'
Ngisho noma iwayini elingenalo utshwala lingenalo lonke utshwala lwewayini elijwayelekile (ngokuvamile cishe ngamaphesenti angu-13-14 ngevolumu), kufanele libe nesilinganiso esifanayo sama- polyphenols amakhemikhali ezitshalo zemvelo ezitholakala ezikhumbini zamagilebhisi (kanye ezinye izithelo, imifino, amantongomane kanye nembewu).
Izinzuzo ze-Antioxidant ze-Polyphenols
Lezi zimakhemikhali zisebenza njengama-antioxidants angavikela amangqamuzana akho emonakalweni omkhulu wamahhala. Iwayini elibomvu linama-polyphenols amaningi kunalabo abamhlophe ngoba izikhumba zamagilebhisi zisusiwe ngaphambi kokwenza iwayini elimhlophe.
Ezinye izifundo ze-epidemiological zithole ukuhlangana phakathi kokuphuza inani elilinganiselwe elincane lewayini elibomvu ngokufa okuncane ngenxa yesifo senhliziyo. Utshwala lungadlala indima ekuvikeleni, kodwa ososayensi bakholelwa ukuthi izakhiwo ze-polyphenols yizizathu eziyinhloko zezinzuzo zezempilo ezingenzeka. Zihlanganisa:
- I-Myricetin
- I-Kaempferol
- Quercetin
- Catechin
- Epicatechin
- I-Proanthocyanidins
- Anthocyanins
- Gallic acid
- I-Caftaric acid
- I-caffeic acid
- I-P-coumaric acid
- I-Resveratrol
Azikho izifundo ezibonisa ukuthi ukuphuza iwayini elidayiswayo lizonciphisa ingozi yakho yezifo ezithile.
Kodwa kukhona ucwaningo oluthile oluqhathaniswa nendlela oluqhathaniswa ngayo newayini elibomvu elivamile lezibalo zegazi zamanye ama-polyphenols nokuthi zithinta kanjani ezinye zamakhamera eziphilayo ezihlobene nesifo senhliziyo.
Lezi zifundo zibonisa ukuthi iwayini elivamile linomthelela omkhulu, kepha iwayini eliphathekayo lithuthukisa amanye alawa makaki.
Yiqiniso, kunezinto eziningi okufanele zicatshangelwe kunokuba amandla okulwa ne-antioxidant. Iwayini elisetshenziselwa ukuthengiswa kwezidakamizwa linamakhilomitha ambalwa kunewayini elibomvu (cishe 1/4 kuya ku-1/3 lama-calories, ngokusho kwabakwa-winemakers), futhi ngeke usebenzise ingozi yokudakwa kakhulu utshwala.
Iwayini elidayiswa ngamafutha liqala njengewayini elivutshiwe langempela, kodwa ngaphambi kokuba libhotshwe, lizohlungwa noma lifakwe inqubo yokuhlunga esusa kokubili amanzi nophuzo oludakayo. Okulandelayo, ivolumu ithathelwe indawo ngamanzi noma inhlanganisela yamanzi nesiphuzo samagilebhisi esingenamvubelo.
I-winecoolzed wine iyanambitha kanjani? Ngicabanga ukuthi ama-oenophile amaningi angabhekana nomehluko ngoba utshwala luba nomthelela omkhulu emzimbeni, e-bouquet nasezingeni elimnandi lamawayini, kokubili obomvu nomhlophe. Amawayini amhlophe athengiswayo amancane asondelene kakhulu nomzala wabo ogcwele utshwala, kepha uma uthanda i-Cabernet enkulu, ephelele, kungathatha isikhashana ukujwayela ukunambitheka okubuthakathaka kwenguqulo ye-dealcoolised.
Kodwa, ngakolunye uhlangothi, alunambitha njengejusi lamagilebhisi noma. Iwayini elibomvu elisetshenzisiwe lisekhona ama-tannins, futhi akulona okomnandi njengejusi elula.
Sicela uqaphele ukuthi nakuba i-dealcoholized iwayini ingenalo utshwala, kufanele uqhubeke ukhuluma nomhlinzeki wakho wezempilo ngaphambi kokuba uyidle uma ukhulelwe noma utshelwe ukuthi udinga ukugwema utshwala.
