Effect of adding fatty acids and surfactant on the functional properties of biodegradable films prepared with myofibrillar proteins from acoupa weakfish (Cynoscion acoupa )

Abstract: This research aimed to assess the properties of biodegradable films prepared with lyophilized myofibrillar proteins (LMP) from fish filleting residues, fatty acids (stearic, palmitic, and caproic), and surfactant (SLS). The films were characterized to assess the effects of adding those components. Adding fatty acids and SLS resulted in more flexible films with higher elongation values compared to the LMP film. The films prepared with 5% stearic acid and 10% SLS and with 10% palmitic acid and 20% SLS had higher… Show more

“…Protein‐based films have better gas and mechanical barrier properties when compared to polysaccharides since proteins have a unique structure, which can confer a more excellent range of functional properties, exceptionally high intermolecular binding potential (Pereira, Pereira, Araujo, et al., 2019; Pereira, Pereira, Neve, et al., 2019). Polysaccharides have adequate gas barrier capacity, but low water vapor transfer barriers as they are hydrophilic (Batista et al., 2019).…”

“…Portanto, as pesquisas sobre novas embalagens de alimentos têm sido direcionadas para a elaboração de filmes e revestimentos à base de biopolímeros, como as proteínas que são totalmente biodegradaveis, contribuindo para diminuir a poluição ambiental (Pereira et al 2019a;Pereira et. al.…”

“…Pereira et al (2019b) também encontraram estruturas homogêneas para filmes de proteínas miofibrilares de peixe com ajuste de pH para 11, no entanto, também mostra a presença de pequenas bolhas de ar devido à formação de espuma durante a homogeneização da solução e trincas (fissuras) na superfície dos filmes podem ter sido produzidas pelo tratamento a vácuo aplicado à amostra antes da realização da microscopia Souza (2013),. afirma que a intensidade de desnaturação e interação das diferentes proteínas ocorre em diferentes formas e intensidade quando se varia o valor de pH do meio em que estas se encontram Pereira et al (2019b)…”
