The gelatinization temperature of starch depends upon plant type and the amount of water present, pH, types and concentration of salt, sugar, fat and protein in the recipe, as well as starch derivatisation technology are used. Some types of unmodified native starches start swelling at 55 °C, other types at 85 °C. [3]
A commonly used estimate of the thermic effect of food is about 10% of one's caloric intake, though the effect varies substantially for different food components. For example, dietary fat is very easy to process and has very little thermic effect, while protein is hard to process and has a much larger thermic effect.
Additionally, consuming protein powder before a workout can help minimize muscle breakdown during exercise and keep blood sugar levels stable, especially when paired with a carbohydrate, says Goodson.
In biochemistry, denaturation is a process in which proteins or nucleic acids lose folded structure present in their native state due to various factors, including application of some external stress or compound, such as a strong acid or base, a concentrated inorganic salt, an organic solvent (e.g., alcohol or chloroform), agitation and radiation, or heat.

Keep in mind protein powder is a dietary supplement, not a substitute, stresses Tyler Becker, Ph.D., an assistant professor in the Department of Food Science and Human Nutrition at Michigan State ...
The granularity of the sugar can greatly affect the reaction: powdered sugar reacts very quickly but sugar cubes take longer to react. [2] When sucrose is dehydrated, heat is given out to the surroundings in an exothermic reaction, while graphite and liquid water are produced by the decomposition of the sugar: [3]
"Protein powder is a dried or dehydrated powder made by separating protein in whole food sources from the other raw ingredients," says Kimberly Evans, RD, a registered dietitian at Fay. "Protein ...
As the protein content of MPC increases, the lactose levels decrease. This high-protein low-lactose ratio makes MPC an appealing ingredient for protein-fortified beverages and foods and low-carbohydrate foods. [2] MPC can make products more heat stable, and it can provide solubility and dispersibility when used. [2]
