Melanins are complex, polymeric pigments with interesting properties like UV-light absorbance ability, metal ion chelation capacity, antimicrobial action, redox behaviors, and scavenging properties. Based on these characteristics, melanins might be applied in different industrial fields food packaging, environmental bioremediation, bioelectronic fields. The actual melanin manufacturing process is not environmentally friendly as it based extraction purification from cuttlefish. Synthetic...

Abstract Allergen detection and quantification is an essential part of allergen management as practiced by food manufacturers. Recently, protein MS methods (in particular, multiple reaction monitoring experiments) have begun to be adopted the community provide alternative technique ELISA PCR methods. analysis proteins in foods provides additional challenges analyst, both terms experimental design methodology: (1) choice analyte, including multiplexing simultaneously detect several...

The aim of this work was to prepare bioplastics, from renewable and biodegradable molecules, be used as edible films. In particular, grass pea (Lathyrus sativus L.) flour biopolymer source, the proteins which were structurally modified by means microbial transglutaminase, an enzyme able catalyze isopeptide bonds between glutamines lysines. We analyzed, Zeta-potential, suspension with determine pH is more stable for production film-forming solutions. bioplastics produced casting they...

Citrus peel pectin was used to prepare films (cast with or without glycerol) containing mesoporous silica nanoparticles. Nanoparticles reduced significantly the particle size, and had no effect on Zeta potential of solutions. Mechanical characterization demonstrates that pectin+nanoparticles slightly increased tensile strength decreased Young’s modulus in comparison made only pectin. However, elongation at break cast presence glycerol, while both were reduced. Moreover, nanoparticles able...

The formulation of eco-friendly biodegradable packaging has received great attention during the last decades as an alternative to traditional widespread petroleum-based food packaging. With this aim, we designed and tested properties polyhydroxyalkanoates (PHA)-based bioplastics functionalized with phloretin far antioxidant, antimicrobial, morpho-mechanic features are concerned. Mechanical hydrophilicity investigations revealed a mild influence on novel materials function concentration...

French fries are popular products worldwide. However, this product is a sufferable source of high acrylamide due to temperature and low moisture. The main objective study was evaluate the effect grass pea flour (GPF), transglutaminase (TGase)-treated (GPF + TGase), chitosan (CH), pectin (PEC) hydrocolloid coating solutions on formation acrylamide, water retention as well oil content. In addition, Daily Intake (DI) Margin Exposure (MOE) were calculated estimate variations in risk assessment...

Bio-plastics and bio-materials are composed of natural or biomass derived polymers, offering solutions to solve immediate environmental issues. Polysaccharide-based bio-plastics represent important alternatives conventional plastic because their intrinsic biodegradable nature. Amylose-only (AO), an engineered barley starch with 99% amylose, was tested produce cross-linked all-natural bioplastic using normal as a control. Glycerol used plasticizer citrate cross-linking improve the mechanical...

Various different agri-food biomasses might be turned into renewable sources for producing biodegradable and edible plastics, potentially attractive food, agricultural cosmeceutical sectors. In this regard, seeds utilized non-edible oil extraction give rise to high amounts of organic by-products, known as seed cakes (SOCs), able become protein-rich resources useful the manufacturing films. This study reports potential SOC derived from Argania spinosa (argan), a well-known plant containing...

This study sheds light on the potential of microbial transglutaminase (mTG)-mediated modification to enhance properties heat-denatured whey protein-based films. In this study, we investigated biochemical proteins (WPs) using mTG, an enzyme known for ability crosslinking reactions. By introducing ε-(γ-glutamyl)-lysine crosslinks via acyl transfer reaction, mTG enhances bio-based materials. research, heated WPs were demonstrated effectively serve as substrates. The preparation crosslinked...

Ca2+-independent transglutaminase isolated from Streptoverticillium mobaraense was used to obtain a novel cheese we called "crosslinked cheese." We characterized both the obtained by adding and milk clotting enzyme at same time, one produced transglutaminase, following cutting of coagulum. In cases, water content yields were higher, whereas protein significantly increased 33.8% 39.5% only in second type crosslinked cheese. Isoelectric focusing extracted prepared samples on thin layer...

Edible films were obtained from Citrus paradisi grapefruit albedo homogenates and bean protein phaseolin modified or not by the enzyme transglutaminase. Swelling capability, barrier performance to water vapor, oxygen carbon dioxide, mechanical properties of such investigated. The addition protein, mostly in presence transglutaminase, provide less swellable at pH values above 5 compared made only, whereas action clearly improves producing more stretchable elastic films. Moreover,...
