摘 要:There are many natural sources to obtain pharmaceutical grade starch, one of which is banana (<i><i><span style="font-family:Verdana;">Musa</span></i><span style="font-family:Verdana;"> × </span><i><span style="font-family:Verdana;">paradisiaca L</span></i><span style="font-family:Verdana;">.</span></i>);nevertheless, the use of native starch has certain disadvantages compared to modified starches, whose disintegrating properties are better. In this study, starch extracted from rejected fruits of <i><i><span style="font-family:Verdana;">Musa</span></i><span style="font-family:Verdana;"> × </span><i><span style="font-family:Verdana;">paradisiaca L</span></i><span style="font-family:Verdana;">.</span></i>, was modified by acetylation, under the following optimized experimental conditions: 130 mL acetic anhydride, 3 mL sodium hydroxide 50% p/v for each 15 grams of native starch, at 123℃ during 3 hours. The reaction resulted in a modified green banana starch with twice as much swelling capacity compared to unmodified (native) starch;acetylation was verified by infrared spectroscopy and degree of substitution of acetyl groups by back titration.
