The non-enzymatic browning (NEB) reaction plays an essential role in food acceptance and quality. There has been increased interest in revealing the role that water plays in native and gelatinized starch. However there is a lack of information on the relationship between the water dynamics of water–starch interactions and the kinetics of NEB reaction in native and gelatinized starch systems. Th...

In the first paper of this series, it was shown that gelatinization of starch was necessary to enhance jelly strength of fish meat jelly (Kamaboko), and that starch added in Kamaboko , though gelatinized, chiefly existed in the jelly as granules and partly dispersed into meat as amylose. In the present paper, amylose and amylopectin, the two components of starch , were isolated by an improved S...

This article reviews the pressure gelatinization of starch with a special focus on potato starch which is a key food ingredient and an industrial raw material. First of all, the application of high hydrostatic pressure (HHP), as a novel processing parameter, to food processing is briefly overviewed with some historical backgrounds. It has been revealed in the last century that a starch-water mi...

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 ...

In extrusion printing, the printability of food materials depends on rheology under shearing when extruded, and at rest, post-deposition. Piloting microstructure to provide rheological properties compatible with 3D printing is a major challenge. Microstructure, rheology, wheat-flour based varying concentrations flour, sugar, oil, water were studied. Materials obtained by heating doughs moisture...
