Starch hydrolysis was conducted using batch culture of Caldimonas taiwanensis which was able to hydrolyze starch completely under the optimal condition of 55 °C and pH 7.5, yielding 0.46–0.53 g reducing sugars per gram of starch [35]. Five H2-producing pure strains and a mixed culture were ...
Hydrolysis and debranching of starch can also affect retrogradation and the formation of resistant starch [154,193]. During and or after the retrogradation, a variety of physical modifications occur, such as the formation of a gel, that increases the viscosity, the turbidity of the product, the...
The hydrolysis progresses by adding NaOH to convert -CONH2 to -COONa, and the adsorption experiments confirmed that the functional group to adsorb heavy metals is -COO, rather than -CONH2. During the determination of heavy metal adsorption, the Na concentration diffused by ...
What stimulates the release of the enzyme amylase into the pancreatic duct so that it can break down starches? How can the biological functions of glycogen and starch be explained in terms of weak interactions? How would you expect the results of starch hydrolysis to change if you will a...
The starch's crystallinity (27.18%) increased with acid hydrolysis (37.54%) and thiolation (41.37%) but decreased with carboxymethylation (23.29%). The highest drug loading (70.23% ± 0.23%) was recorded for carboxymethylated nanocrystals, then thiolated nanocrystals (63.37% ± 0.40%), and the...
The hydrolysis progresses by adding NaOH to convert -CONH2 to -COONa, and the adsorption experiments confirmed that the functional group to adsorb heavy metals is -COO-, rather than -CONH2. During the determination of heavy metal adsorption, the Na+ concentration diffused by SR-16 into the ...
Why do higher temperatures give the highest rate of hydrolysis in starches? Explain why alum crystals have to be washed with a 50:50 mixture of ethanol and water. Why should a chromatography column never be allowed to go dry condition? Why does having a high electronegativity signif...

Larger size granules tend to swell more than smaller granules, whereas smaller size granules are more susceptible to enzymatic hydrolysis. The outer surface of starch granules also plays a key role in many applications of starch. Electron microscopic images have revealed that tuber and root starches...
Starch hydrolysis rate was enhanced by roasting, popping, and flaking processes, whereas cooking and extrusion did not change the starch digestibility rate from the values found in the raw seeds during the assay period. The predicted GI for raw seeds, cooked, extruded, popped, flaked, and ...
