Co-precipitation of the starches was carried out using acetone as the precipitating agent. A 1:1, ratio of maize starch and rice starch were used to prepare the starch co-precipitate. The starches were first dispersed in warm water in separate beakers; both of the starch dispersions were brought to the same temperature (40oC), mixed together and stirred for five minutes. The mixture of the starches was precipitated using acetone and the mixtures were washed severally with acetone until a strong non-slimy starch was obtained. The co-precipitates were dried in a tray dryer (Manesty Ltd, Liverpool, England), pulverized in an end runner mill (Pascal ngineering co Ltd, England) and finally passed through 1.0 mm sieve (Turgens & Co., Germany).
