1. Ukufuma kwamagqabi okutsha.Ngokuqhubeka kokulahleka kwamanzi amagqabi asematsha, isixa esikhulu semixholo yalo iya kubola, ifakwe i-oxidized kwaye ilahleke, nto leyo eya kuchaphazela umgangatho weti ngeqondo elincinci, kwaye iya kukhokelela ekuwohlokeni.ikhefu elitshas kwaye ulahlekelwe ixabiso lezoqoqosho kwiimeko ezinzima.Ngoko ke, ukuze kugcinwe iti entsha, indlela yokutshiza iqhele ukwamkelwa ukuze kugcinwe indawo yokugcina amagqabi kwindawo yokufuma ephezulu.

2. Ubushushu.Ubushushu bangaphandle buchaphazela ikakhulu ukuphefumla kwamagqabi amatsha.Ukuphakama kwamaqondo obushushu, amandla okuphefumla kwamagqabi amatsha, kwaye ubushushu beqabunga buphezulu, komelela umsebenzi we-enzyme, ongahambelani nomgangatho weti.Ke ngoko, ubushushu obuphantsi obufanelekileyo bunceda ukugcina ubutsha bamagqabi eti.

3. Ioksijini.Ukuba umoya uphantsi ngexesha lokugcinwa, ukuphefumla kweti ye-anaerobic kuya kwandisa umsebenzi we-enzyme, kukhawulezise ukubola kwezinto eziphilayo, kunye nokwandisa i-oxidation ye-polyphenols.Kwinkqubo ye-hypoxia, amagqabi amatsha aya kuthi ngokuthe ngcembe avelise ivumba elibi okanye incasa emuncu, eya kuthi ichaphazele kakubi ivumba elibi.iti egqibile.Ke ngoko, ekuvuneni amagqabi amatsha, ukuthuthwa, kunye nokugcinwa kwamayeza emveli aseTshayina, gcina ukujikeleza komoya ukuthintela ukuphefumla kwe-anaerobic kwamagqabi amatsha kunye nokuchaphazela umgangatho weti.

4. Oomatshiniumonakalo.Emva kokuba amaqabunga amatsha afumana umonakalo owenziwe ngoomatshini, kwelinye icala, ukuphefumla kwamagqabi amatsha kuba namandla kwaye ubushushu beqabunga bukhuphuka ngokukhawuleza;kwelinye icala, ibangela i-enzymatic oxidation yeepolyphenols, ethanda ukutshintsha igqabi elibomvu.
