A polyelectrolyte complex (PEC) matrix formed between chitosan and pectin was developed to entrap a bioactive compound (anthocyanin), obtaining an useful pH indicator device. Polysaccharides of opposite charges such as can have very strong intermolecular interaction. The innovation lies in new system based on natural biodegradable compounds, which is simple manufacture, indicate variation by visual changes colour. This device has potential applications food packaging. PEC studied using...
Abstract Kraft paper was coated with chitosan emulsion film. The novelty of this is the formation a packaging bilayer system in only one drying step, which combines biodegradable polymer (chitosan and palmitic acid) paper. This described detail characterized for barrier properties (water vapor permeability rate (WVPR), air water absorption capacity (Cobb test)), mechanical (tensile properties, Taber stiffness tear strength) structural properties. application coating (3.5 g m −2 , wet basis)...
A polyelectrolyte complex system of chitosan-pectin nano- and microparticles was developed to encapsulate the hormone insulin. The aim this work obtain small particles for oral insulin delivery without chemical crosslinkers based on natural biodegradable polysaccharides. were using chitosans (with different degrees acetylation: 15.0% 28.8%) pectin solutions at various charge ratios (n⁺/n- given by chitosan/pectin mass ratio) total charge. Nano- characterized regarding particle size, zeta...
Fresh salmon safety and quality is a major concern of consumers. In the current research, effects chitosan films incorporated with pink pepper residue extract combined modified atmosphere packaging (100% CO2) on properties skinless fillets during refrigerated storage (2 °C) were evaluated in course 28 days. Two different treatments as film (CF) (CFPP) control compared. Salmon assessed for physicochemical (pH, WHC, TPA, Cie L*a*b*, TMA, TBA, value K), microbiological (mesophilic...
The biodegradability of chitosan is significant for packaging systems. Another relevant property its degree acetylation (DA), which affects other properties, such as crystallinity and hydrophobicity. DA can be modulated by chitin deacetylation or even reacetylation. novelty this paper the application reacetylated a coating cardboard surfaces to improve barrier mechanical properties paper. Chitosan with 2% was yield 48% DA. Both samples were applied coating, coated materials characterized....
Chitosan films are commonly used for wound dressing, provided that this polymer has healing, mucoadhesiveness and antimicrobial properties. These properties can be further reinforced by the combination of chitosan with polysaccharides glycoproteins present in aloe vera, together copaiba oleoresin's pharmacological activity attributed to sesquiterpenes. In work, we developed containing either oil or both, casting technique, evaluated their microbial permeation, activity, cytotoxicity, vivo...
Temperature greatly affects the food quality and safety. control is an important condition during distribution storage. An intelligent biodegradable temperature indicator packaging material was developed based on a natural heat-sensitive pigment (anthocyanin – ATH). Different concentrations of ATH were incorporated into chitosan matrix films (2.00%, w/w) that applied as surface coating card paper, forming paper system (CH-Sys). The novelty this work alternative biodegradable, simple...
Abstract With the aim of achieving ‘tailor‐made’ chitosan films, effects several variables on properties films were studied. These concentration and molecular weight thermally depolymerized chitosan, addition lipids (palmitic acid, beeswax or carnauba wax) plasticizer (glycerol). The water vapour transmission rate (WVTR) mechanical these measured. innovative feature this study is that it provides specific information to support design tailor‐made films. can only be formulated when important...
Nutritionally enhanced pasta was developed by adding dried leaves of Pereskia aculeata Miller, known as ora-pro-nobis (OPN). The OPN are edible wild plants, underused and unknow plants. incorporation flour (OPN-F) into a regularly eaten food product, such pasta, could be healthy low-cost strategy to improve nutrient intake promote an exploration new fresh market food. aim this study develop product containing OPN-F, improving the protein, dietary fibre, calcium iron characterize its...
By-products from the juice industry contain a large proportion of high-value compounds, such as polyphenols, that can be applied natural antioxidants in foods. The effects grape pomace flour (GPF) were assessed on oxidative stability, physicochemical, and sensory characteristics frozen salmon burgers. Two batches burgers formulated with 1% 2% GPF. For comparison purposes, negative control (0% GPF) burger added 0.01% BHT formulated. incorporation GPF into altered color appearance, but did not...
Chitosan films have been extensively studied as dressings in formulations for the treatment of chronic wounds. The incorporation aloe vera (Aloe barbadensis Miller) into chitosan could potentialize healing process since shows several pharmacological activities. This work aimed to evaluate effect and concentrations on physicochemical properties developed films. were obtained by casting technique characterized with respect their color parameters, morphology, barrier mechanical properties,...
Circular economy, and concerns about environmental waste, is fostering the development of sustainable alternative products in a range industries. In dermo-cosmetic field, market for anti-aging skincare has increasingly grown over last years. The innovation this work was to develop chitosan films incorporating lemongrass essential oil (LEO) that could potentially be applied as green cosmetic skin treatment due their anti-oxidant antimicrobial properties, using renewable biodegradable...
An active film-forming solution of chitosan and lemongrass essential oil was applied as a coating on paperboard, forming an alternative sustainable packaging material for food applications.
