Amatchedwanso wowuma zotumphukira, amene amapangidwa ndi thupi, mankhwala kapena enzymatic kuchitira ndi wowuma mbadwa kusintha, kulimbikitsa kapena kuwononga katundu watsopano ndi molecular cleavage, rearrangement kapena kuyambitsa magulu atsopano m'malo.Pali njira zambiri zosinthira wowuma wa chakudya, monga kuphika, hydrolysis, oxidation, bleaching, oxidation, esterification, etherification, crosslinking ndi zina.
Kusintha kwathupi
1. Pre-gelatinization
2. Chithandizo cha radiation
3. Chithandizo cha kutenthaKusintha kwa mankhwala
1. Esterification: Wowuma wa acetylated, esterified ndi acetic anhydride kapena vinyl acetate.
2. Etherification: Hydroxypropyl starch, etherified ndi propylene oxide.
3. Acid mankhwala wowuma , mankhwala zidulo inorganic.
4. Alkaline ankachitira wowuma, ankachitira zinthu zamchere zamchere.
