“…The increased resistance of the films can be attributed to the formation of intermolecular hydrogen bonds between hydroxyl groups of CNC and amino groups of gelatin chains, reducing their ability to interact with water molecules. Maroufi et al [49] found in their study that the addition of modified carrageenan in gelatin reduced the solubility and moisture content of the films. They mentioned that this is due to the formation of crosslinking bonds between the amino groups from gelatin and the dialdehyde from modified carrageenan, leading to a denser structure with reduced water absorption ability and water binding capacity.…”

Increasing interest on sustainable agriculture has led to the development of new materials which can be used as seed coating agents. In this study, a new material was developed based on gelatin film reinforced with cellulose nanocrystals (CNC) which was further used as nanocomposite matrix for Trichoderma harzianum KUEN 1585 spores. The nanocomposite films were characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and scanning electron microscopy (SEM), showing the formation of new hydrogen bonds between the components with a good compatibility between them. Measurements of water contact angles and tests of water vapor sorption and swelling degree revealed an improvement in the water vapor absorption properties of the films as a result of their reinforcement with CNC. Furthermore, by adding the Trichoderma harzianum KUEN 1585 spp. in the seed coating material, the germination percentage, speed of germination and roots length of the corn seeds improved. The polymeric coating did not inhibit the growth of T. harzianum KUEN 1585, with this material being a good candidate in modern agriculture.

“…Heat treatments in the presence of reducing sugars, known as the Maillard reaction, have been demonstrated to lead to a crosslinking process and modified network structure [ 157 ]. Very recently, Maroufi et al [ 158 ] demonstrated the chemical crosslinking of fish gelatin with the aldehyde groups of K-carrageenan.…”

Fish waste is attracting growing interest as a new raw material for biopolymer production in different application fields, mainly in food packaging, with significant economic and environmental advantages. This review paper summarizes the recent advances in the valorization of fish waste for the preparation of biopolymers for food packaging applications. The issues related to fishery industry waste and fish by-catch and the potential for re-using these by-products in a circular economy approach have been presented in detail. Then, all the biopolymer typologies derived from fish waste with potential applications in food packaging, such as muscle proteins, collagen, gelatin, chitin/chitosan, have been described. For each of them, the recent applications in food packaging, in the last five years, have been overviewed with an emphasis on smart packaging applications. Despite the huge industrial potential of fish industry by-products, most of the reviewed applications are still at lab-scale. Therefore, the technological challenges for a reliable exploitation and recovery of several potentially valuable molecules and the strategies to improve the barrier, mechanical and thermal performance of each kind of biopolymer have been analyzed.
