Active coatings of thermoplastic starch and chitosan with alpha-tocopherol/bentonite for special green coffee beans

Properties of films and coatings added of tocopherol for food packaging: tool-based review for systematic reviews and bibliometric analysis

“…From this point on, for a better understanding of the subject, it was decided to separate the discussion topic from the articles that dealt with the properties of films and the properties of coatings added of tocopherol for use in food packaging. However, when analyzing Table 1, it can be seen that of the articles that developed coatings, only the work by Ferreira et al (2021) evaluated the properties of the material developed, while the articles by Shokri and Ehsani (2017) and Keshari et al (2022) evaluated the properties of the food systems to which the coatings were applied, only Ferreira's work will be discussed together with the articles that determined the properties of the tocopherol films, precisely because in this work a film was also developed to carry out the evaluations, while the articles by Shokri and Ehsani (2017) and Keshari et al (2022) will be discussed in Section 5.1.3.…”

“…Barrier properties have also been extensively studied. Some articles have reported increased water vapor permeability (WVP) (Darbasi et al, 2017;Martelli et al, 2017;Sun et al, 2017a, b;Dias et al, 2018;Agudelo-Cuartas et al, 2020;Lopes et al, 2020;Ferreira et al, 2021;Jiang et al, 2021;Yeamsuksawat and Liang, 2019) others the decrease of this parameter, attributed to the tocopherol applied to the polymer (Li et al, 2019;Mellinas et al, 2020;Mirzaei-Mohkam et al, 2020;Rosenbloom and Zhao, 2020;Yan et al, 2019;Zhang et al, 2020b).…”

Interaction between thermoplastic starch and cellulose in poly (butylene adipate-co-terephthalate) composites with cellulosic fillers

“…15,19 Starch granules can undergo a specific thermomechanical process (for example extrusion) in an excess of water with the aid of plasticizers to obtain thermoplastic starch (TPS) 20 which can replace polymers or can be used as loose fillers in many applications such as food packaging, 21 compostable foams, 22 disposable diapers 23 or even coatings. 24 In this context, addition of cellulose to polyester matrices is a subject of importance, 46 but the production of a composite material with good mechanical and physico-chemical properties strongly depends on the interphase. 47 In fact, the interaction between the matrix and the filler creates an interphase with chemical and mechanical characteristics different from those of the composite components.…”

Efeito de coberturas comestíveis a base de quitosana e extrato de romã em parâmetros de qualidade de queijo coalho

“…A exemplo, tem-se então a quitosana, que consiste em um produto natural derivado da quitina e produzido a partir de resíduos de crustáceos marinhos ou por algumas espécies fúngicas, possuindo caráter não tóxico, biodegradável e biocompatível com sistemas biológicos [10], alta disponibilidade, com propriedades distintas, inclusive antimicrobianas, e excelente capacidade de formação de filme, apresentando-se como um dos polissacarídeos mais estudados na aplicação de embalagens de alimentos [11]. Pesquisas vêm sendo desenvolvidas na produção de coberturas à base de quitosana para alimentos diversos, como morango [12,13], café [14], couve folhas [15], manga [16], e também em produtos de origem animal, como carne [17] e queijo [18]. Sobre este último, diferentes tipos têm sido estudados, sendo observada a eficiência na aplicação de tal cobertura com a finalidade de prolongar a vida útil dos produtos [19].…”
