“…The band corresponding to asymmetric stretching vibrations of the methylene group occurs at approximately 2931 cm −1 [42]. The stretching vibration of the carboxylate anion -COO − exhibits two characteristic absorption peaks at 1590 and 1411 cm −1 , corresponding to asymmetric and symmetric stretching vibration of the carboxylate group, respectively [43][44][45]. The band at approximately 1034 cm −1 corresponds to C-O stretching in the acetyl groups present on the SA backbone [8].…”

A sodium alginate/chitosan solution was prepared by dissolving sodium alginate, chitosan, and glycerol in an acetic acid solution. This solution was then combined with a sodium carboxymethyl cellulose solution and the mixture was cast onto a glass plate and dried at a constant temperature of 60 • C. Then, a carboxymethyl cellulose/sodium alginate/chitosan composite film was obtained by immersing the film in a solution of a cross-linking agent, CaCl 2 , and air-drying the resulting material. First, the most advantageous contents of the three precursors in the casting solution were determined by a completely random design test method. Thereafter, a comprehensive orthogonal experimental design was applied to select the optimal mass ratio of the three precursors. The composite film obtained with sodium alginate, sodium carboxymethyl cellulose, and chitosan contents of 1.5%, 0.5%, and 1.5%, respectively, in the casting solution displayed excellent tensile strength, water vapor transmission rate, and elongation after fracture. Moreover, the presence of chitosan successfully inhibited the growth and reproduction of microorganisms. The composite film exhibited antibacterial rates of 95.7% ± 5.4% and 93.4% ± 4.7% against Escherichia coli and Staphylococcus aureus, respectively. Therefore, the composite film is promising for antibacterial food packaging applications.

“…Carboxymethyl cellulose (CMC) is a type of cellulose derivatives that effectively extend the shelf life of fruits and vegetables. An aqueous solution of CMC has good film‐forming properties and forms a dense protective film on the surface of fruits and vegetables, which reduces the light transmittance and slows the respiration (Akhtar et al, ). Chitosan was demonstrated to have good antibacterial and film‐forming effects.…”

Polysaccharides from Osmunda japonica Thunb (Op) exhibit a wide range of biological activities including antibacterial, anti‐inflammatory, antioxidant, and antitumor effects. Carboxymethyl cellulose (CMC) is a type of cellulose derivative that can form dense films. CMC can slow the respiratory transpiration of tomatoes and reduce water evaporation. Coatings of CMC (0.7% concentration) with various levels of Op (0.02%, 0.04%, 0.06%, 0.08%, and 0.1%) were used to preserve tomatoes at room temperature. The treatment, weight loss, hardness, titratable acidity (TA), respiratory intensity, and concentrations of ascorbic acid, polyphenol oxidase, and malondialdehyde (MDA) were evaluated in tomatoes after 0, 5, 10, 15, 20, and 25 days of storage. Compared with untreated tomatoes, the tomatoes with Op‐incorporated CMC coatings had reduced respiratory intensity, weight loss and ascorbic acid loss, increased TA, controlled MDA, and inhibited the decay of tomatoes. Therefore, the use of Op‐incorporated CMC coatings extended the shelf life and maintained the quality of postharvest tomatoes. Practical applications In the past decades, the use of edible coatings has attracted widespread interest in extending the shelf life of particularly perishable foods. Currently, applications of edible coatings have been proven to be promising as a tool to improve the quality and extend the shelf life of various fruits. But there have been no reports on the effect of Op‐incorporated CMC treatment on the postharvest quality of tomatoes during storage. The purpose of this work is to investigate the efficiency of Op‐incorporated CMC treatment to extend shelf life and provide theoretical guidance for the preservation of tomatoes.

Traditional packaging materials with single function or weak activity cannot meet the requirements of active packaging. In this study, antimicrobial carboxymethyl cellulose (CMC)‐based nanocomposites containing montmorillonite (MMT) and ε‐poly‐(l‐lysine) (ε‐PL) were prepared by solution casting method. The morphological, optical, mechanical, barrier, thermal, and antimicrobial properties of the resulted ternary nanocomposites were investigated. The surface morphology of the films was dependent on the contents of the ε‐PL used. The incorporation of MMT and ε‐PL into CMC matrix improved the UV barrier property, tensile strength, hydrophobicity, and water vapor barrier property. When incorporation of 7.5 wt % ε‐PL, the tensile strength increased more than threefold and the water vapor permeability decreased by about 35% compared with pure CMC film, the water contact angle reached up to the highest value of 65.38°. The ε‐PL incorporated CMC/MMT films exhibited good antimicrobial activities against Gram‐positive (Staphylococus aureus) and Gram‐negative (Escherichia coli) bacteria and fungi (Botrytis cinerea and Rhizopus oligosporus). Microbial growth inhibition rate of above 90% was obtained when the content of ε‐PL got up to 7.5 wt %. In addition, CMC/MMT/ε‐PL7.5 wt % film‐forming solution having the appropriate properties was used as coating for the strawberries preservation, the shelf life of strawberries was extended for 2 days. © 2019 Wiley Periodicals, Inc.
