“…Thickness values varied between 41.9 and 43.9 μm, indicating that acerola extract did not modify the film density ( p > .05). Similar results have been informed for chitosan films added of biological extracts derived from plants (Capello, Leandro, et al, 2021; Merz et al, 2020).…”

“…In the second scan (results not shown), both chitosan films displayed DSC thermograms of amorphous materials, hence, no glass transition was observed in this scan. Similar results have been informed in the literature for chitosan films (Capello, Leandro, et al, 2021;Capello, Trevisol, et al, 2021).…”

Sodium metabisulfite is a chemical compound used to reduce melanosis of shrimps. However, this chemical compound has been associated with several human diseases and negative environmental impacts. Therefore, this study aimed to develop, characterize, and apply a coating and film based on natural and not toxic compounds. A chitosan‐based coating and a film containing acerola fruit powder were developed and characterized for various physicochemical and microstructural properties. The presence of acerola altered the chitosan interactions, hence, the chitosan film containing acerola had fewer crystal structure, reducing its hydrophobicity. Furthermore, the presence of acerola imparted an orange color in chitosan film when compared with chitosan film without acerola (transparent). The chitosan solution containing acerola was as effective as sodium metabisulfite solution in controlling the melanosis and lipid oxidation of the shrimps. The developed chitosan coating containing acerola can be used to control melanosis during shrimp storage and to reduce or to eliminate the use of the metabisulfite. Novelty impact statement The active coating based on chitosan and acerola fruit is a new alternative to control melanosis of shrimps during storage at 5°C. Hence, the use of this eco‐friendly active coating could reduce the use of chemical toxic compounds such as sodium meta‐bisulfites.

“…To date, different types of natural pigments, including anthocyanins, chlorophyll, and curcumin, have been embedded in polysaccharide-/protein-based matrices to produce freshness indicating films [ 7 , 8 ]. Among them, anthocyanins are frequently selected for the production of freshness indicating films, because anthocyanins have wide distributions in plants (e.g., vegetables, fruits, grains and flowers) and possess excellent antioxidant and color-changeable properties [ 9 , 10 ]. Meanwhile, anthocyanins are safe and edible, while showing beneficial health effects [ 11 ].…”

Freshness indicating films containing anthocyanins are one type of smart packaging technology. Anthocyanins in the films can show visual color changes when food spoilage occurs, thereby indicating the freshness degree of food in real-time. Rhododendron simsii is a landscape plant with attractive flowers that are abundant in anthocyanins. In this study, smart packaging films were prepared by embedding 2% and 4% R. simsii flower anthocyanins (RA) in locust bean gum- (LBG) and polyvinyl alcohol- (PVA) based matrices. The micro-structure, barrier, mechanical, thermal, antioxidant, and color-changeable properties of the films were determined. The potential application of the films in indicating the freshness of shrimp at 4 °C was also investigated. Results showed that the RA interacted with the LBG/PVA matrices through hydrogen bonds, which significantly improved the barrier, mechanical, thermal, antioxidant, pH-sensitive, and ammonia-sensitive properties of the films. Meanwhile, the performance of the films was remarkably influenced by the content of the RA. The film containing 4% RA had the highest light blocking ability, tensile strength (38.32 MPa), elongation at break (58.18%), and antioxidant activity, and also showed the lowest water vapor permeability (22.10 × 10−11 g m−1 s−1 Pa−1) and oxygen permeability (0.36 cm3 mm m−2 day−1 atm−1). The films containing 2% and 4% RA could effectively change their colors when the level of total volatile basic nitrogen in the shrimp exceeded the safe value, which demonstrated the suitability of the films for indicating the freshness degree of shrimp.

Chitin‐Based Functional Films for the Colorimetric Detection of Ethylene Glycol

We developed a new method for producing large‐area color thin films for the colorimetric detection of ethylene glycol. This method is based thermal evaporation of chitin. This process enables easy manipulation of the thickness and color patterns of the film by using shadow masks and repeated evaporation. We used this film to demonstrate a colorimetric sensor for the detection of ethylene glycol gas. The use of chitin allows the manufacture of inexpensive and environment‐friendly gas detectors. When the film was exposed to target gas, the film reacted with ethylene glycol and hydroxyl group on the chitin‐film by etherification. Then the films underwent both chemical and structural changes, resulting in color changes at low ppm concentrations. We were able to compare the sensor reaction to gases with and without the hydroxyl group. The selectivity of the sensor was confirmed by analyzing the gas containing the hydroxyl group through the linear discriminant analysis (LDA) method. We expect that our results will be utilized to provide low‐cost and low‐power systems for gas monitoring.This article is protected by copyright. All rights reserved.
