Fabrication and application of functional active packaging material based on carbohydrate biopolymers formulated withLemon verbena/Ferulago angulataextracts for the preservation of raw chicken meat

Abstract

In this research using Zedo gum (ZG) and carboxymethyl cellulose (CMC) as well as Lemon and Ferulago extracts (LVE/FAE) new active packaging was designed. Biodegradable films with five various proportions of ZG to CMC were made by applying the casting process. The incorporation of LVE or FAE into CMC/ZG composite films significantly reduced moisture content (MC) and water vapor permeability (WVP). The tensile strength increased from 6.92 (MPa) for CMC/ZG film to 11.51 MPa for CMC/ZG/2.5 μl LVE and FAE film; as well as elongation at break decreased from 24.21% for CMC/ZG film to 6.10% for CMC/ZG/2.5 μl LVE and FAE film. In conclusion, the 20:80 proportion of ZG/CMC along with 2.5 μl LVE and FAE can be used as the best ratio for mechanical properties, moisture content, and permeability compared to the CMC/ZG film with individual FAE or LVE and can be a good source for making edible films. Novelty impact statement The most important novelty is related to using of Lemon verbena and Ferulago angulata extracts in the combination of Zedo gum and carboxymethyl cellulose. Producing active packaging with Lemon verbena and Ferulago angulata extracts in polymer matric. Increasing the shelf life of compounds such as raw chicken meat with active packaging.

Sodium alginate/carboxymethyl cellulose films embedded with liposomes encapsulated green tea extract: characterization, controlled release, application

“… 61 The weak barrier properties of CMC to water depended on the presence of hydrophilic groups in the polymer matrix. 62 In this study, the range of values optimized by a single-factor experiment was selected for SA addition (0.5 wt%, 0.75 wt%, 1 wt%), CMC addition (0.25 wt%, 0.5 wt%, 0.75 wt%), and Lip addition (1.5 wt%, 2 wt%, 2.5 wt%) for BBD design ( Fig. 4 ).…”

Investigation of the Release Rate of Biocide and Corrosion Resistance of Vinyl-, Acrylic-, and Epoxy-Based Antifouling Paints on Steel in Marine Infrastructures

“…The paints were applied to the plates using a 60 µm applicator at 22-25 • C, and the curing time was determined based on the ISIRI6456 standard [54,55]. All tests were carried out three times to minimize error and ensure the repeatability of data.…”

The Use of Biopolymers as a Natural Matrix for Incorporation of Essential Oils of Medicinal Plants

“…Thus, materials based on biopolymers with incorporated essential oils have been developed. Initially, they were used in the food industry to improve the sensorial quality or to increase the shelf life of various food products, such as those based on meat or fish [ 19 , 20 , 21 , 22 ], fruits or vegetables [ 23 , 24 , 25 ], sweets [ 26 , 27 ], beverages [ 28 ] or dairy products [ 29 , 30 ]. Later, they were added to increase the nutritional value and bioavailability of products, especially those with beneficial effects on health.…”
