“…The film made from the cultivar Jalpa conserved this barrier from 300 to 800 nm. This behavior is similar to that reported by Fang et al [30], Nouraddini et al [2] and Thakur et al [48], due to the nature of the polymer used. Regardless of the plasticizer used, with increasing wavelength, the light transmission rate increased, and it was too difficult to determine the relationship between the transparency and compounds in the films [28].…”

“…The values of the white standard plate were L* = 96.9, a* = −0.04 and b* = 1.84. The YI was calculated according to Pérez-Mateos et al [24] using Equation (2). Five measurements were taken from each treatment, with three determinations from different areas of the edible film.…”

“…In the last several years, interest in the production of edible films has increased because they present a series of advantages, such as prolonging the shelf life of foods and reducing the use of plastics. Therefore, many film-forming materials such as starch [1][2][3][4], gelatin [5], chitosan [6][7][8], cellulose [9], carboxymethyl cellulose [10], methylcellulose [11], pectin [12,13], agar [14], alginate [15,16], carrageenan [16], zein [17], etc., have been used. Mucilage from Mexican Opuntia ficus-indica is suitable for large-scale production due to its abundance in Mexico, low cost, nontoxicity, biodegradability, biocompatibility, film-forming capacity, and renewability.…”

The consumption of organic products has increased in recent years. One of the most important products in Mexico is nopal. Nopal’s content and properties make the formulation of edible films possible. In this study, we aimed to develop and characterize biodegradable edible films containing mucilage from Opuntia ficus-indica. The mucilage extraction yield, thickness, color, water vapor permeability, light transmission rate, film transparency, solubility, stability of dispersion, and puncture strength were measured. The use of mucilage from different cultivars affected the water vapor permeability (8.40 × 10−11 g·m−1·s−1·Pa−1 for cultivar Villanueva, 3.48 × 10−11 g·m−1·s−1·Pa−1 for Jalpa, and 1.63 × 10−11 g·m−1·s−1·Pa−1 for Copena F1). Jalpa provided the most soluble mucilage with the highest thickness (0.105 mm). Copena F1 provided the clearest film with the greatest transparency (3.81), the best yellowness index, and the highest resistance (4.44 N·mm−1). Furthermore, this film had the best light transmission rate (48.93%). The Copena F1 showed the best film formation solution viscosity. These results indicate that mucilage mixed with pectin is a potential source for the formulation of edible films.

“…Due to the consumption of fossil fuels and the rise of environmental pollution, many scientists are directing their research towards ''green'' plastics (Stevens 2003). One of the most important renewable resources used in the plastics industry is biomass from wood (Zimmermann et al 2014;Bi et al 2018;Guo et al 2018) and crop plants (Karimia et al 2017;Hejna et al 2018a, b;Hemamalini and Dev 2018): corn (Nouraddini et al 2018), soy (Dhaliwala et al 2018, potatoes (Bergel et al 2018), cassava (Luchese et al 2017) and other edible plants (Ubeyitogullari and Ciftci 2016;Halal et al 2015). Due to the controversial use of food resources, there is a need to find sustainable non-food renewable sources.…”

Chemical structures, rheological and physical properties of biopolyols prepared via solvothermal liquefaction of Enteromorpha and Zostera marina biomass

et al. 2019

In this work, liquefied biomass from the Baltic Sea was used for the preparation of rigid polyurethane (PUR) foams. The biomass contained 10 wt% of Enteromorpha macroalgae and 90 wt% of Zostera marina seagrass characterized by a high content of cellulose. The influence of time, temperature and the type of solvent on the efficiency of the liquefaction process and properties of biopolyols was determined. Obtained materials were analyzed in terms of chemical structure, rheological properties, thermal stability and basic physical and mechanical properties. It was found that optimal parameters for liquefaction of used biomass were: temperature of 150°C, reaction time of 6 h and a solvent mixture containing glycerol and poly(ethylene glycol) in ratio of 50:50 (biopolyol 50G50P_150). Under these conditions, 78 wt% of biomass was liquefied and resulting biopolyol was characterized by a hydroxyl number of 650 mg KOH/g. Depending on the used solvent mixture and the liquefaction temperature, biopolyols showed the character of Newtonian or non-Newtonian liquids. Rigid PUR foams were obtained by substitution of petrochemical polyol with 10, 20 and 30 wt% of biopolyol. It was found that the addition of biopolyol to foams' formulations did not cause significant changes in their chemical structure, while mechanical strength and thermal stability were enhanced. The presented study confirms that biomass from the Baltic Sea can be used for the synthesis of biopolyols and rigid polyurethane foams.

“…Various biopolymers, such as protein, cellulose, chitosan, and starch, have been recently studied as biodegradable film materials . Among them, starch is an abundant and inexpensive material that can be readily used to form a biodegradable film . Another potential material is rye ( Secale cereal L.).…”

Antioxidant Properties of Rye Starch Films Containing Rosehip Extract and Their Application in Packaging of Chicken Breast

Starch Stärke

View full text Add to dashboard Cite

Starch is extracted from rye and used as a film base material to develop a new biodegradable film. Different concentrations (0.4, 0.7, and 1.0 g per 100 mL) of rosehip extract (RHE) are incorporated as active materials to enhance the physicochemical properties of rye starch films. As the RHE concentration increases, the tensile strength of rye starch films decreases and elongation at break increases, resulting in improved flexibility of the films. The optical properties of the films are also enhanced by increasing opacity and decreasing light transmittance. Ultraviolet light is completely blocked. The antioxidant activities of the films are determined by evaluating 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activities. The highest ABTS and DPPH radical scavenging activities are observed for 1.0% RHE films (96.87% and 80.22%, respectively). Chicken breast samples wrapped with the 1.0% RHE film have lower peroxide and thiobarbituric acid reactive substances values than samples wrapped with film not containing RHE as well as the non-packaged control, suggesting that lipid oxidation in the chicken breast is inhibited by the inclusion of RHE. The results indicate that rye starch films incorporated with RHE can be used as an active packaging material to retard lipid oxidation in foods.
