Shaah madow, oo loo yaqaan dhadhankiisa hodanka ah iyo kan adag, waa cabitaan caan ah oo ay ku raaxaystaan malaayiin qof oo adduunka ah. Mid ka mid ah dhinacyada xiisaha leh ee shaaha madow waa midabkiisa casaanka ah ee gaarka ah marka la sameeyo. Maqaalkani wuxuu higsanayaa inuu sahamiyo sababaha cilmiyeed ee ka dambeeya midabka cas ee shaaha madow, isagoo iftiiminaya hababka kiimikada ee gacan ka geysta dhacdadan.
Midabka cas ee shaaha madow waxaa loo aanayn karaa joogitaanka iskudhisyo gaar ah oo sameeya isbeddello kiimiko ah inta lagu jiro habka sameynta shaaha. Iskudhisyada ugu muhiimsan ee mas'uulka ka ah midabka cas waa thearubigins iyo theaflavins, kuwaas oo lagu sameeyo oksaydheynta polyphenols-ka shaaha inta lagu jiro habka halsano ama oksaydheynta ee shaaha madow uu maro.
Inta lagu jiro soo saarista shaaha madow, caleenta shaaha waxaa la mariyaa taxane habab ah, oo ay ku jiraan qallayl, rogidda, oksaydhaynta, iyo qallajinta. Waa inta lagu jiro marxaladda oksaydhka in polyphenols-ka shaaha, gaar ahaan catechins, ay maraan oksaydhaynta enzymatic, taasoo horseedaysa sameynta thearubigins iyotheaflavinsIsku-darkaan ayaa mas'uul ka ah midabka cas ee hodanka ah iyo dhadhanka gaarka ah ee shaaha madow.
Thearubiginsgaar ahaan, waa iskudhisyo waaweyn oo polyphenolic ah oo midabkoodu yahay casaan-bunni. Waxaa lagu sameeyaa polymerization-ka catechins iyo flavonoids kale oo ku jira caleenta shaaha. Dhanka kale, theaflavins waa iskudhisyo yaryar oo polyphenolic ah oo sidoo kale gacan ka geysta midabka cas ee shaaha madow.
Midabka cas ee shaaha madow waxaa sii xoogeysanaya joogitaanka anthocyanins, kuwaas oo ah midabyo biyo ku milma oo laga helo noocyada shaaha qaarkood. Midabyadan waxay siin karaan midab casaan ah shaaha la kariyey, taasoo ku kordhinaysa midabka guud ee shaaha.
Marka laga soo tago isbeddellada kiimikada ee dhaca inta lagu jiro habaynta shaaha, arrimo ay ka mid yihiin noocyada kala duwan ee dhirta shaaha, xaaladaha beerista, iyo farsamooyinka habaynta ayaa sidoo kale saameyn kara midabka cas ee shaaha madow. Tusaale ahaan, heerka oksaydhka, muddada halsano, iyo heerkulka lagu farsameeyo caleenta shaaha ayaa dhammaantood saameyn kara midabka ugu dambeeya ee shaaha la sameeyay.
Gunaanadkii, midabka cas ee shaaha madow waa natiijada isku-dhafka adag ee isku-dhafka kiimikada iyo hababka ku lug leh soo-saarkiisa. Thearubigins, theaflavins, iyo anthocyanins ayaa ah kuwa ugu muhiimsan ee ka qaybqaata midabka cas ee shaaha madow, iyadoo samayskooda iyo is-dhexgalkooda inta lagu jiro farsamaynta shaaha ay keentay midabka iyo dhadhanka gaarka ah ee cabitaankan la jecel yahay.
