Formulation and Characterization of Edible Films Based on Organic Mucilage from Mexican Opuntia ficus-indica

Abstract

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.

Formulation and Characterization of Antimicrobial Edible Films Based on Whey Protein Isolate and Tarragon Essential Oil

“…In HT films, it ranged from 2.1 and 5.6 N/mm, decreasing with the addition of tarragon essential oil up to formulation F2, then increasing in F2.5. Comparable levels of PR, ranging between 3.83 and 4.44 N/mm, were found in edible films prepared from mucilage powders of three cultivars of Opuntia ficus-indica (0.5%), pectin (0.7%), glycerol (1%), and (97.8%) water [ 39 ]. Higher levels of PR were reported by Jiang et al (2010) in edible film prepared with 10% WPI, 4% glycerol, and 86% water (of 25.0 N/mm), and by Machado Azevedo et al (2017) in edible film prepared with 60% corn starch/WPI blend (1:1, w / w ), 24% glycerol, and 16% water (of 11.5 N/mm) [ 34 , 40 ].…”

Effect of Sonication on the Properties of Flaxseed Gum Films Incorporated with Carvacrol

“…3.6. WVP WVP (g H 2 Om −2 s −1 MPa −1 ) of FG-C films was calculated through gravimetric analysis according to González Sandoval et al [56] with a few modifications. Anhydrous CaCl 2 was placed in an acrylic cup with the top of the CaCl 2 about 5 mm from the mouth of the cup.…”

Properties and Application of Multifunctional Composite Polypropylene-Based Films Incorporating a Combination of BHT, BHA and Sorbic Acid in Extending Donut Shelf-Life

“…A gravimetric ASTM E96-16 method [59] was applied to evaluate water permeability of films according to González Sandoval et al [60] with few modifications. Conditioned film discs (Ø = 16 mm, 55% relative humidity, RH) were sealed to glass vials of 45 mm height with a hole of 8 mm on the cap containing anhydrous CaSO 4 (0% RH), and the vials were weighed and transferred into a desiccator maintained at 97% RH with a saturated salt solution of potassium sulphate at 25 • C. The weight gain of the vials was measured periodically over a total time of 96 h, which indicated the amount of water vapour transferred from the films or water vapour transmission rate (WVTR).…”
