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.

Antifoaming agents reduce or prevent foaming in foods. Antioxidants Antioxidants such as vitamin C act as preservatives by inhibiting the effects of oxygen on food, and can be beneficial to health. Bulking agents Bulking agents such as starch are additives that increase the bulk of a food without affecting its nutritional value. Food coloring
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 ...
A chaotropic agent is a substance which disrupts the structure of, and denatures, macromolecules such as proteins and nucleic acids (e.g. DNA and RNA).Chaotropic solutes increase the entropy of the system by interfering with intermolecular interactions mediated by non-covalent forces such as hydrogen bonds, van der Waals forces, and hydrophobic effects.
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.
Isoflavones (phytoestrogens) use the 3-phenylchromen-4-one skeleton (with no hydroxyl group substitution on carbon at position 2). Daidzein (formononetin) soy, alfalfa sprouts, red clover, chickpeas, peanuts, kudzu, other legumes. Genistein (biochanin A) soy, alfalfa sprouts, red clover, chickpeas, peanuts, other legumes. Glycitein soy. Isoflavanes
The scientific approach to food and nutrition arose with attention to agricultural chemistry in the works of J. G. Wallerius, Humphry Davy, and others.For example, Davy published Elements of Agricultural Chemistry, in a Course of Lectures for the Board of Agriculture (1813) in the United Kingdom which would serve as a foundation for the profession worldwide, going into a fifth edition.
