Denaturation is the process by which foods or liquids are made unpleasant or dangerous to consume; it is done by adding a substance known as a denaturant. Aversive agents —primarily bitterants and pungent agents —are often used to produce an unpleasant flavor.
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.

The crusts of most breads, such as this brioche, are golden-brown mostly as a result of the Maillard reaction.. The Maillard reaction (/ m aɪ ˈ j ɑːr / my-YAR; French:) is a chemical reaction between amino acids and reducing sugars to create melanoidins, the compounds that give browned food its distinctive flavor.
An example of a strong alkaline cleaning agent is sodium hydroxide, also called caustic soda. Although sodium hydroxide (NaOH) can cause corrosion on food contact surfaces such as stainless steel, it is the preferred cleaning agent for protein removal due to its efficacy in dissolving proteins and dispersing/emulsifying food soils.
New tests done by the Environmental Working Group have found 21 oat-based cereals and snack bars popular amongst children to have "troubling levels of glyphosate." The chemical, which is the ...
Gelatin is an irreversibly hydrolyzed form of collagen, wherein the hydrolysis reduces protein fibrils into smaller peptides; depending on the physical and chemical methods of denaturation, the molecular weight of the peptides falls within a broad range.
Flavor-wise and chemical-wise, Spindrift gets some of the highest marks, with 0.19 ppt PFAS, or parts per trillion ("safe" PFAS levels are seen as being below 1 ppt).
Chemical denaturation [ edit ] In the less extensive technique of equilibrium unfolding , the fractions of folded and unfolded molecules (denoted as p N {\displaystyle p_{N}} and p U {\displaystyle p_{U}} , respectively) are measured as the solution conditions are gradually changed from those favoring the native state to those favoring the ...
