ABSTRACT High-molecular-weight dextrin (WS-1000) was produced from waxy corn starch and enzymatically modified to link glucose by ?-1,6 glycosidic bond at the terminal point of chain, forming MWS-1000. In this study, physical properties MWS-1000 were characterized, advantages its use as a food modifier described. From rheological calorimetric studies, it found that does not undergo retrogradati...

Microencapsulation as one of the most modern methods has considerable effects on probiotic survival. In this study Lactobacillus casei (ATCC 39392) and Bifidobacterium bifidum (ATCC 29521) were encapsulated using calcium alginate-gelatinized starch, chitosan coating and inulin via emulsion technique, and were incubated in simulated gastric juice (along with pepsin, pH=1.5) and simulated intesti...

The normality dependence and the kinetics of flow behavior in the rice starch dispersion under strong alkali conditions were studied. Non-Newtonian flow (power-law) quantities n and μ (σ = μ(̇); σ: shear stress, ̇: shear rate) of the samples stored (gelatinized) at 20◦C for 10min after the addition of NaOH solution with the normality 0.090 0.175N, were measured by a cone-plate type rotational v...

In this study, the interactions of wheat starch (WS) and tannic acid (TA) were investigated for their gelatinization, pasting, structural, rheological properties digestibility starch. TA was either complexed with (WS-TA complexes) or mixed mixtures) right before characterization its properties. The increase melting enthalpy temperature range (Tpeak - Tonset) associated amylose-lipid complex in ...

A novel enzyme immobilization approach was used to generate mesoporous enzymes-silica composite microparticles by co-entrapping gelatinized starch and cross-linked phenylalanine ammonia lyase (PAL) aggregates (CLEAs) containing gelatinized starch into biomemitic silica and subsequently removing the starch by α-amylase treatment. During the preparation process, the gelatinzed starch served as a ...

Effects of added wheat fiber, with different levels and particle sizes, on the physicochemical properties and gel morphology of wheat starch and mung bean starch were investigated, using rapid visco analyzer (RVA), texture analyzer (TPA) and scanning electron microscopy (SEM). Each starch was added with wheat fiber at 10, 20, 30 and 40% (weight basis, g/100g), and different sizes of 60, 100 and...

Corn starch showed higher fresh paste consistency than wheat starch, and, after aging 24 hr, its gels were more firm at 6% solids or less. Between 7 and 30% solids, gels of wheat starch were more firm than those of corn starch. The lipids in wheat and corn starches were reduced 88-97% by boiling three times in four parts of a 3:1 (v/v) mixture of ethanol/water. Iodine-binding capacity of corn a...

The influence of the composition and method preparation gelatinized starch compositions on their relative viscosity is studied. activation energy viscous flow developed formulations was determined. change in polymer dressing from time to

The purpose of this study was to assess the properties of resistant starch (RS) III prepared from elephant foot yam starch using pullulanase enzyme. Native and gelatinized starches were subjected to enzymatic hydrolysis (pullulanase, 40 U/g per 10h), autoclaved (121°C/30 min), stored under refrigeration (4°C/24h) and then lyophilized. After preparation of resistant starch III, the morphological...
