Heat coagulation is the easiest and the oldest method of protein recovery, albeit the least preferred as most of the nutritive value of the LPC is lost. Acid precipitation is the most commonly employed method of protein recovery although it results in the loss of methionine and tryptophan in the LPC. Ultrafiltration is the most hardware ...
Protein crystallization is more successful for proteins with a higher melting point [8] and adding buffer components that stabilize proteins improve the likelihood of protein crystals forming. [9] If examining pH then the possible effects of the buffer molecule on thermal stability should be taken into account along with the fact that pKa of ...
Crystal structure of β-glucosidase from Thermotoga neapolitana (PDB: 5IDI).Thermostable protein, active at 80°C and with unfolding temperature of 101°C. [1]In materials science and molecular biology, thermostability is the ability of a substance to resist irreversible change in its chemical or physical structure, often by resisting decomposition or polymerization, at a high relative ...
The dramatic upregulation of the heat shock proteins is a key part of the heat shock response and is induced primarily by heat shock factor (HSF). [6] HSPs are found in virtually all living organisms, from bacteria to humans. Heat shock proteins are named according to their molecular weight.
Food preservation may also include processes that inhibit visual deterioration, such as the enzymatic browning reaction in apples after they are cut during food preparation. By preserving food , food waste can be reduced, which is an important way to decrease production costs and increase the efficiency of food systems , improve food security ...
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.

Brining – Food processing by treating with brine or salt; Ceviche – Dish of marinated raw seafood; Charcuterie – Branch of cooking of prepared meat products, primarily from pork; Cured fish – Fish subjected to fermentation, pickling or smoking; Curing salt – Salt used in food preservation
Ultra-high temperature processing (UHT), ultra-heat treatment, or ultra-pasteurization [1] is a food processing technology that sterilizes liquid food by heating it above 140 °C (284 °F) – the temperature required to kill bacterial endospores – for two to five seconds. [2]
