Molecular gastronomy is the scientific approach of cuisine from primarily the perspective of chemistry. The composition (molecular structure), properties (mass, viscosity, etc) and transformations (chemical reactions, reactant products) of an ingredient are addressed and utilized in the preparation and appreciation of the ingested products.
Sous vide cooking using thermal immersion circulator machines. Sous vide (/ s uː ˈ v iː d /; French for 'under vacuum' [1]), also known as low-temperature, long-time (LTLT) cooking, [2] [3] [4] is a method of cooking invented by the French chef Georges Pralus in 1974, [5] [6] in which food is placed in a plastic pouch or a glass jar and cooked in a water bath for longer than usual cooking ...
Microorganisms growing on an agar plate. Sterilization (British English: sterilisation) refers to any process that removes, kills, or deactivates all forms of life (particularly microorganisms such as fungi, bacteria, spores, and unicellular eukaryotic organisms) and other biological agents (such as prions or viruses) present in or on a specific surface, object, or fluid.

Air-free techniques refer to a range of manipulations in the chemistry laboratory for the handling of compounds that are air-sensitive. These techniques prevent the compounds from reacting with components of air, usually water and oxygen; less commonly carbon dioxide and nitrogen. A common theme among these techniques is the use of a fine (10 0 ...
There are several type of distillation: simple distillation, steam distillation etc. Water purification combines a number of methods to produce potable or drinking water. Downstream processing refers to purification of chemicals, pharmaceuticals and food ingredients produced by fermentation or synthesized by plant and animal tissues, for ...
Laboratory quality control is designed to detect, reduce, and correct deficiencies in a laboratory's internal analytical process prior to the release of patient results, in order to improve the quality of the results reported by the laboratory. Quality control (QC) is a measure of precision, or how well the measurement system reproduces the ...
brine. To soak a food item in salted water. broasting. A method of cooking chicken and other foods using a pressure fryer and condiments. browning. The process of partially cooking the surface of meat to help remove excessive fat and to give the meat a brown color crust and flavor through various browning reactions.
Round-bottom flasks (also called round-bottomed flasks or RB flasks) are types of flasks having spherical bottoms used as laboratory glassware, mostly for chemical or biochemical work. [1] They are typically made of glass for chemical inertness; and in modern days, they are usually made of heat-resistant borosilicate glass.
