Is The starch in the pizza crust turns to sugar physical or chemical change?
chemical change
Is bread iodine solution a physical or chemical change?
Chemical- Iodine reacts with the starch of the bread.
Is dextrinization the same with gelatinization?
no. gelatinization - starch granules when they heated in a liquid. Irreversable dextrinization - breakdown of starch molecules to smaller, sweeter in the presence of dry heat.
Is burning bread a physical or chemical change?
It is a chemical change. because starch present in bread is converted into carbon and carbon dioxide and reverse of the process is not possible.
2 Why do different starches have different gelatinization temperature ranges?
because starch have different composition
Is starch molecules that are formed from smaller glucose molecules a chemical or physical change?
The changing of extra glucose into starch is a chemical change.
Is The starch in the pizza crust turns to sugar physical or chemical change?
chemical change
Is dissolving starch in water physical or chemical change?
physical chage
Is the starch in the pizza crust turns to sugar is the physical change?
Chemical

no. gelatinization - starch granules when they heated in a liquid. Irreversable dextrinization - breakdown of starch molecules to smaller, sweeter in the presence of dry heat.
What is the Principle of gelatinization?
The principle of gelatinization lies in the item arriving at high heat fairly quickly. Starch can help gelatinization through its thickening agents.
Is making play dough from corn starch and conditioner a physical or chemical reaction?
It would be a chemical change/reaction.
Is burning bread physical or chemical change?
It is a chemical change. because starch present in bread is converted into carbon and carbon dioxide and reverse of the process is not possible.
Is burning bread a physical or chemical change?
It is a chemical change. because starch present in bread is converted into carbon and carbon dioxide and reverse of the process is not possible.
Is yeast causing bread to rise is a physical or chemical change?
Yeast rising bread works because yeast (an organism) converts starch to carbon dioxide which makes bread grow. This can be seen as a chemical reaction (yeast converting starch to CO2 gas) or a physical reaction (the CO2 making the bread expand).
What happens when gelatin is heated?
Gelatinization is the swelling and disruption of molecules in a starch granule when heated in water. It happens at around 55 to 85°C. Gelatinization results in loss of crystallinity or birefringence, irreversible swelling of the starch granule, increase of viscocity of solution, leaching of amylose from the starch granule, and a creating more clear solution.
