biodegradable films based on cassava starch/mentha piperita essence: fabrication, characterization and properties
in this study, the effect of mentha piperita essence (mpe) incorporation into cassava films on the hydrophilic and physicochemical properties of the resulting biodegradable films was investigated. the properties included solubility, moisture uptake and contact angle. mpe was added into biodegradable films at different amounts (1, 2 and 3%, w/w total solid). all biofilms were plasticized with 40...
متن کاملEffect of carboxymethyl cellulose concentration on physical properties of biodegradable cassava starch-based films
BACKGROUND Cassava starch, the economically important agricultural commodity in Thailand, can readily be cast into films. However, the cassava starch film is brittle and weak, leading to inadequate mechanical properties. The properties of starch film can be improved by adding plasticizers and blending with the other biopolymers. RESULTS Cassava starch (5%w/v) based films plasticized with glyc...
متن کاملRice Starch-Based Biodegradable Films: Properties Enhancement
The claims of environmental protection and the lack of petroleum resources provide a new opportunity for developing plastic materials derived from biopolymer resources. Starch is one of the most studied and promising raw materials for the production of biodegradable plastics, because starch is quite cheap, abundant, biodegradable and edible. Starch consists of two major types of molecules, prim...
متن کاملPhysicochemical Properties of Edible and Preservative Films from Chitosan/Cassava Starch/Gelatin Blend Plasticized with Glycerol
Edible films from chitosan, cassava starch, and gelatin plasticized with glycerol have been developed by casting method, and the effects of cassava starch (50, 100 and 150 g per 100 g of chitosan), gelatin (0, 25 and 50 g per 100 g of chitosan) and glycerol (21, 42 and 63 g per 100 g of chitosan) from the film solution on various properties of chitosan-based films have been studied using respon...
متن کاملProperties of Biodegradable Multilayer Films Based on Plasticized Wheat Starch
Over the last decades, there has been growing needs to find alternatives to petroleum-based products because of environmental concerns. Starch is an inherently biodegradable, renewable and low-cost material, and has high potential in food or non-food applications [1]. In that respect, the applications of starch have given rise to a great number of studies [2–5]. Native starch, when plasticized ...
