Effect of relative humidities on microstructural, barrier and mechanical properties of Yam starch-monoglyceride films

Abstract

ABSTRACT

Isolation, Composition, Structure, Properties, Modifications, and Uses of Yam Starch

“…Starches of D. alata and D. trifida in both native and cross‐linked forms were used to produce biodegradable starch films, and the drying conditions and ingredient composition were related to various physical properties (water barrier, mechanical, and thermal) of the films (Mali and others , , ; Mali and Grossmann, ; Durango and others ; Ferreira and others ; Pérez and others ; Reis and others ). Monoglyceride was incorporated into starch film to prevent phase separation, while decreasing water permeability and increasing stability of the film (Ferreira and others ). Monoglyceride forms a V‐type inclusion complex with the amylose component, fixing the starch components in the film matrix (Ferreira and others ).…”

“…Monoglyceride was incorporated into starch film to prevent phase separation, while decreasing water permeability and increasing stability of the film (Ferreira and others ). Monoglyceride forms a V‐type inclusion complex with the amylose component, fixing the starch components in the film matrix (Ferreira and others ). Cross‐linked starch was used to make native film and the resulting sample had greater width, opalescence, and water permeability than that of native starch (Pérez and others ).…”

Influence of thickness on properties of plasticized oat starch films

“…Studies have focused on the development of biodegradable packaging from the renewable sources and among the natural polymers, starch has become one of the most promising candidates due to its high availability, renewability and low cost (Tang et al 2012). Starches from different sources have been investigated regarding their film formation properties (Ferreira et al 2009;Melo et al 2011;Maran et al 2013). Starch shows thermoplastic behavior; however, if used pure, forms brittle films with lower flexibility requiring the addition of a plasticizer (Galdeano et al 2009a).…”

Extruded cylindrical strands: Mechanical properties correlated with the formation of biodegradable films through blown extrusion

“…The majority of studies on biodegradable films are focused on casting method [5–10], but the blown extrusion is a more cost effective processing method, since it is faster, requires less space, and demands a smaller number of production stages compared with casting. Extrusion is also the method utilized in large‐scale production of commercial films.…”
