Prodn. of dry flakes or granules useful as base for pasta involves drying a mixt. of 30-95 (wt.)% carboxymethylated and/or alkoxylated starch, 3-40 cellulose ether and 2-40% water-dispersible or water-soluble polymer contg. ca. 30-80% water, opt. with additives, e.g. preservatives, wettinq agents, fillers etc., in a thin film on surfaces by heating to 80-200 deg. C. Pref. drying is carried out in 2-60, pref. 5-25 s at ca. 100-160 deq. C and pref. on rollers or a belt drier. Pref. the carboxymethylated and/or alkoxylated starch is treated with crosslinkers and pref. has a deq. of carboxymethylation of 0.1-2.0 and/or deg. of alkoxylation of 0.05-1.5. The cellulose ether is slightly ethoxylated methylcellulose, methyl-hydroxypropyl-cellulose and/or CMC; and the polymer is polyvinyl acetate, polyacrylate or EVA, pref. in the form of a dispersion, of water-soluble PVA, PVP or polyvinylmethyl ether.
