Bioactive Peptides: Synthesis, Properties, and Applications in the Packaging and Preservation of Food

Abstract

: Bioactive peptides are protein fragments which have a positive impact on the functions and conditions of living beings. Peptides have shown several useful properties for human health, including antimicrobial, antifungal, antiviral, and antitumor activities. These compounds are produced by almost all species of life. However, they are produced in limited quantities in nature. As a result, researchers have tried to synthesize bioactive peptides to study their properties and applications in various areas. Among their applications in food preservation, peptides have been incorporated into packaging materials. This review begins with a brief description of the methods used for the synthesis, purification, and characterization of peptides. Also, the main bioproperties and mechanisms of action of peptides are discussed. Finally, some applications of peptides are presented, especially their use in active packaging, their effects on the polymeric matrix, and peptide migration.

Peptide-based imaging agents for cancer detection

“…In both cases, the tumor uptake of nanoparticles with active targeting RGD peptides was much higher than those without RGD modification. Although conjugation of different peptides to the surface of nanoparticles provides an effective way to develop target-specific multimodal imaging agents, the formation of chemical bonds may interfere with the targeting ability [106,118]. …”

Antimicrobial peptides as natural bio-preservative to enhance the shelf-life of food

“…Purification technique should be easy and simple with minimum processing. For large scale purification of antimicrobial peptides, at least two types of chromatographic techniques are used in combination such as ion exchange chromatography and gel permeation followed by HPLC (Espitia et al 2012). …”

Covalent Immobilization of Lysozyme on Ethylene Vinyl Alcohol Films for Nonmigrating Antimicrobial Packaging Applications

“…The antimicrobial properties are associated with the hydrolysis of peptidoglycan in the Gram-positive bacteria cell wall. 33,34 Lysozyme is more active against Gram-positive bacteria than against Gram-negative, because their cell wall is mainly composed of peptidoglycan (90%). In the case of Gramnegative organisms, they have a greater defense system and only 5−10% of the cell wall is constituted by peptidoglycan.…”
