Abstract

This research was aimed at characterization of maltodextrin DP 3-9 (produced by enzymatic hydrolysis and membrane separation process) as compared to commercial maltodextrin and glucose and assessment of its potential application as carbohydrate source in sport drink. The research showed that application of maltodextrin DP 3-9 had some advantages as compared to glucose with regard to absorption rate that was 2 times longer (60 minutes instead of 30 minutes), osmolality degree that was 5,6 times lower (178 mOsmol/kg as compared to 1000 mOsmol/kg), and relative sweetness degree that was 10 - 11 times lower (6,15-7,20 as compared to 57,00-61,00). However, thie application of maltodekstrin DP 3-9 had limitation which was shown by its viscosity characteristic that was 5,70 -- 6,20% higher (1,29 cSt and 1,37 cSt as compared to 1,22 cSt and 1,29 cSt). When compared to commercial maltodextrin, maltodextrin DP 3-9 is favorable as carbohydrate source in sport drink based on its absorption rate that was more than 2 times faster (60 minutes as compared to more than 120 minutes) and storage stability at refrigeration temperature (which was more than 8 weeks, with or without sterilization; with sterilization). Key words : Maltodextrin DP 3-9, carbohydrate source and sport drink

Abstract

This research was aimed to characterize sweet potato flour var. shiroyutaka and assessment of its potential as alternative carbohydrate source on food product. Characterization was conducted on flour processed from sweet potato var. shiroyutaka harvested at four months was characteristic, these included whiteness degree and water absorption of the flour, ratio of amylase-amylopectin, form and size of starch granule, and starch digestibility. The research showed that whiteness degree and water absorption of the flour were 78,82% ( 0,52) and 1,25 g/g ( 0,12) respectively. The ratio of amylase-amylopectin, gelatinization temperature, maximum viscosity and invitro starch digest ability were 69.82%: 30.18%, 78-900C and 84,78% respectively. The granule of its starch was round form and with size 2-4 micron. The main potential of the flour is related with its specific characteristics which were the amylose-amylopectin ratio, the starch amylograph profile, form and size of starch granule, and the starch digest ability. These parameters implied that, the flour should be utilized in the production specific food products. Key words : sweet potato flour, amylose, gelatinization, digest ability, water absorption

Abstract

 Cooking loss and elongation are primary noodle quality parameters that depend on microstructure of the noodle. The noodle microstructure is strongly influenced by degree of gelatinization, moisture content, and shear force experienced by the dough. These parameters are controlled by temperature and screw speed of the extruder. The objective of this research was to optimize three processing variables i.e., corn flour moisture (70, 75, 80% dry basis), extruder temperature (80, 85, 90°C), and screw speed (110, 120, 130 rpm). Corn noodles were processed using Scientific Laboratory Single Screw Extruder type LE25-30/C. Optimizations Using Response Surface Methodology were based on four parameters, i.e., hardness, stickiness, elongation, and cooking loss characteristics .Results showed that the optimum processing condition was obtained at moisture of 70% (dry basis), extruder temperature 90°C, and screw speed 130 rpm. Under this condition, corn noodles has hardness of 3039.79 gf, stickiness of -116.2 gf, elongation of 318.68%, and cooking loss of 4.56%.
