Amino acids and biogenic amines as food quality factors

Abstract

The importance of amino acids and biogenic amines is widely recognised in various fields, particularly in the fields of food science and nutrition. This mini-review contains a summary of my main research field that centres on aspects of Food Quality and Food Safety, with a particular emphasis on amino acids and biogenic amines. It also gives an overview of the recent developments on the related areas.

Effects of monoacylglycerols and chitosan on the biogenic amine formation in the flesh of rainbow trout (Oncorhynchus mykiss)

“…PUT was present in all our samples, but CAD only in some of them. This is so because PUT is a substance present in all living cells (Sarkadi 2019). Chitosantreated samples did not contain any CAD, especially at the beginning of storage.…”

Selected Instrumental Techniques Applied in Food and Feed: Quality, Safety and Adulteration Analysis

“…As acrylamide, BAs are products from different reactions suffered by certain free amino acids generated by proteolysis processes during some foods’ storage due to some microorganisms’ (MOs) intrinsic metabolism. These MOs can be part of the associated flora of food or introduced by contamination before, during, or after processing [ 353 , 354 , 355 , 356 , 357 , 358 ].…”

“…There are intestinal amine oxidases that can rapidly metabolize and detoxify these compounds. In particular, biogenic amines are found in a higher concentration in those foods that are obtained by a microbial fermentation process, such as cheese, beer, wine, soy-based ferments, and fermented dry sausages [ 355 , 356 , 360 , 361 , 362 , 363 , 364 , 365 , 366 ].…”

“…There are a plethora of publications regarding analytical methods for the determination and quantification of biogenic amines, including spectrophotometry, fluorimetry, electrophoresis, immunoassays [including ELISA], biosensors, and chromatography [ 353 , 354 , 355 , 356 , 357 , 358 ]. The LC technique is the most used for food analysis.…”

“…For example, Sagratini and coworkers successfully separated eight biogenic amines in fish [ 371 ]. Regarding detection, most researchers use electrospray ionization with positive polarity (ESI + ) [ 369 ] due to the cationic nature of amines and multiple reaction monitoring (MRM) [ 355 , 372 ]. The mass spectrum’s base peak and isolated precursor ion was an m/z signal that corresponds to the protonated molecule [M+H] + [ 371 , 372 ].…”
