(Table 1). The acetylated starches
showed lower Ac% than 2.5 g/100g which is percentage of acetyl
groups maximum recommended by FDA for foods uses (Code of
Federal Regulations, 1994). Vasanthan, Sosulski, and Hoover
(1995) in acetylations of 26 g/100g starch slurries reported an Ac
% between 1.01 and 2.80 g/100g in several starches (potato, waxy
corn, corn, wheat, field pea and lentil) using 5 and 10 g/100g of
acetic anhydride. Liu, Ramsden, and Corke (1997) verified an Ac%
between 2.71 and 4.22 g/100g and a DS of 0.105e0.165 in acetylated
maize starches, using 10 g/100g of acetic anhydride in starch slurry
of 31 g/100g. Differences in DS and Ac% can be attributed to the type
of reagent, concentration, pH, presence of catalyst, reaction time,
