Cov txheej txheem ntawm kev ua paj tshuaj yej muaj cov organic ua ke ntawm floral fragrance thiab tshuaj yej adsorption. Thaum lub concentration ntawm floral molecules tso tawm los ntawm paj yog ntau dua li cov concentration ntawm lwm cov roj molecules nyob rau saum npoo ntawm cov tshuaj yej, cov tshuaj yej yuav adsorb ib tug loj npaum li cas ntawm floral molecules tso tawm los ntawm paj. Piv txwv li, jasmine ntsuab tshuaj yej.
Tshuaj yej yog ib qho khoom siv organic, thiab nws lub peev xwm adsorption nce nrog qhov nce ntawm cov tshuaj yej noo noo cov ntsiab lus. Kev txhim kho ntawm cov tshuaj yej adsorption muaj peev xwm feem ntau yog vim qhov kev hloov pauv ntawm cov polarity ntawm cov tshuaj molecular loj hauv tshuaj yej los ntawm cov dej noo, uas ua rau kom muaj kev sib raug zoo ntawm cov molecules saum npoo thiab cov ntxhiab molecules hauv tshuaj yej.
Cov txheej txheem fermentation ntawm paj tshuaj yej yog cov txheej txheem uas cov tshuaj yej nplooj ncav cuag adsorption equilibrium nyob rau hauv ib tug siab concentration aromatic molecule ib puag ncig. Lub fermentation ntawm paj tshuaj yej yog ua kom lub peev xwm adsorption ntawm cov tshuaj yej nplooj, ua kom cov tshuaj tsw qab tso tawm muaj peev xwm ntawm paj, thiab ua tiav qhov zoo tshaj plaws adsorption tshuav.
