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 ...

PURPOSE A cell line spontaneously derived from human retinal pigment epithelium (hRPE) was cultured on alginate film gelatinized with different concentrations of neurobasal cell culture medium (NCCM) to assess its growth and morphological behavior on this naturally occurring polysaccharide. METHODS Neonatal human globes were used to isolate hRPE cells. They were cultured in Dulbecco's modifie...

A variety of water-retaining hydrogels possessing macroporous interiors resembling a honeycomb framework were developed by free radical polymerization acrylamide (AM), starch, and TEMPO-oxidized nanofibrillated cellulose (TONFC) (Poly (AM-co-TONFC/Starch) (PATS) hydrogels). With the help ultrasound, nano precipitated calcium carbonate (NPCC) was gelatinized in preformed NPCC suspension monomer ...

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...
