Effect of different protein extracts from Dosidicus gigas muscle co-products on edible films development

Effect of Different Polyalcohols as Plasticizers on the Functional Properties of Squid Protein Film (Dosidicus Gigas)

“…One of the most important fisheries in Mexico is the jumbo squid; therefore, it is important to propose how to manage the generated waste. For this, several options can be possible; however, the use of myofibrillar proteins to made films have been considered recently [6,7].Myofibrillar proteins can be employed for film formation if the forming solution is adjusted to a higher or lower pH than that of the isoelectric point, to obtain complete solubilization [8]. However, in order to provide biopolymers with workability, plasticizer agents are needed, with the primary role of improving flexibility.…”

“…Moreover, due to hydroxyl groups, the hydrophilicity of the plasticized films could be incremented [12].It must be noted that the use of a biopolymer film for a certain purpose will depend on several features including cost, availability, functional attributes, mechanical properties (strength and flexibility), optical quality (gloss and opacity), barrier requisites (water vapor, O 2 and CO 2 permeability), structure resistance to water, and sensorial acceptance, among others. The aforementioned features will also be affected by the plasticizer used.Even though squid protein films have previously been elaborated/synthesized, only glycerol was used as plasticizer agent [6,7]. Therefore, it is necessary to establish the effect on film behavior and how properties are affected when different plasticizers are used.…”

“…In this work, the effect of glycerol, sorbitol, maltitol, D-mannitol, and xylitol (Figure 1) on the optical and mechanical properties of jumbo-squid protein film were studied. The purpose was to observe changes in the films' behavior and to determine the most appropriate according to the material's final application.Coatings 2019, 9, 77 3 of 12 Even though squid protein films have previously been elaborated/synthesized, only glycerol was used as plasticizer agent [6,7].

Wheat gluten/montmorillonite biocomposites: Effect of pH on the mechanical properties and clay dispersion

“…This could explain the decreased values of Young's modulus and tensile strength obtained for the WGGW-SH samples. The increase in the strain at break value obtained under acid conditions (WGGW-SA) could be explained by an increased interaction between plasticizer and protein [31]. Conformational changes in the molecular structure of wheat gluten are produced when the pH is modified from its isoelectric point, generating the movements of the protein chains and allowing a higher sliding of plasticizer through them.…”

The Potential of Proteins for Producing Food Packaging Materials: A Review

“…27,28 In the case of wet processing, the type of solvent or dissolution pH exerts an effect, as it can affect the conformation of protein, as in the case of zein or myofibrillar proteins. 17,29,30 Furthermore, specific covalent bonds can be established through the addition of chemical or enzymatic cross-linkers that act by different mechanisms; more information can be found in the section 'Cross-linking'.…”
