Abstract. The modern food industry and tolerant starch as raw material from preparation to storage starch using hydroxypropylation the lack of native arrowroot starch modifications applied were sodium tri meta phosphate/STMP (1 phosphate/STPP (4%, 5% the composition of the amylose and amylopectin and in the granules. Higher amount content, which increased link. Arrowroot starch that propylene oxide and 1-2% STMP phosphorus content.

IntroductionArrowroot starch derived from tuber of starches, arrowroot starch modern food industry and a variety of food products require raw material for processing in a broad range of techniques, to storage and distribution. Dual modification of arrowroot using hydroxypropylation and cross-linking was carried out to overcome ack of native arrowroot starch in food processing application. The odifications applied were: combined propylene oxide (8%, 10%, and 12%); sodium tri meta phosphate/STMP (1%, 2%, and 3%); and sodium tri poly %, and 6%). These modifications significantly affected amylose and amylopectin and the amount of phosphorus . Higher amounts of phosphate salt gave a higher phosphorus the degree of substitution (DS) and the degree of crosslink. Arrowroot starch that was modified using a concentration of 8-10% 2% STMP : 3-5% STPP produced a starch with < 0.4% A higher concentration of propylene oxide provided a higher degree of hydroxypropyl. The changed physical properties of the arrowroot starch were examined through SEM testing, and its crystalline patterns through X-ray diffraction measurements. Especially, high concentration of propylene oxide (12%) combined with 3% affected the granular morphology and the crystallinity.
