The retrogradation rate of waxy rice starch gel was investigated during storage at temperatures in the vicinity of the glass transition temperature of a maximally concentrated system (T g '), as it was hypothesized that such temperatures might cause different effects on retrogradation. The T g ' value of fully gelatinized waxy rice starch gel with 50% water content and the enthalpy of melting r...

A 60-day feeding trial was conducted to delineate the effect of three dietary levels of gelatinized starch on fatty acid profiles and RNA and DNA contents of fingerlings of the Indian major carp, Labeo rohita, reared at ambient water temperature (26±0.8°C) or 32°C. Two hundred and sixteen fingerlings (6.5±0.3 g) were randomly distributed into six treatments in triplicate. Three semi-purified is...

This paper puts forward a novel non-ionic augmentation system, namely, gelation of native starch in the presence of borax and papermaking fibers. Native starch was blended with high concentration pulp and auxiliary agents. After pasting, the starch gel adhered onto fiber surfaces. However, an excess dosage of agents led to a rigid structure and poor gel strength. Starch became gelatinized and t...

The graft copolymerization of methacrylic acid onto gelatinized potato starch has been carried out at 70 0 C using chromic acid as initiator. The different reaction parameters such as effect of temperature, initiator and monomer concentrations were optimized to determine the maximum percentage grafting. The maximum grafting efficiency of 87.5% was optimized at reaction temperature (60 0 C), mon...

It is thought that digestion of hydrogen bonds results in the unwinding of the double helices of parallel α-1,4 glucan chains in the crystal lamellae of amylopectin molecules. Th...

It has been well established that a certain amount of ingested starch can escape digestion in the human small intestine and consequently enters the large intestine, where it may serve as a carbon source for bacterial fermentation. Thirty-eight types of human colonic bacteria were screened for their capacity to utilize soluble starch, gelatinized amylopectin maize starch, and high-amylose maize ...

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...

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 ...
