Improvement Physical Properties of Pullulan-Whey Protein Biocomposite Films with Nanoclay
Authors: not saved
Abstract:
In the current study, whey protein- pullulan- clay nanocomposite films are prepared by casting method. The effect of nanoclay at three concentrations (1%, 3% and 5%) on physical properties such as moisture content, solubility in water, water vapor permeability and transparency of whey protein- pullulan composite films investigated. The results show that the effect of nanoparticles on composite depends on kind of nanoparticle and level of incorporation. Nanoclay particles changed solubility, water absorption and moisture content of the films but did not influence on transparency.

full textPreparation and Characterization of Pullulan-Soy Protein Concentrate Biocomposite Film
The non-biodegradable nature of plastic packaging has brought about an attention in bio-basedpackaging materials. Edible composite films were prepared using soy protein concentrate (SPC) and pullulan(PUL) biopolymer at five different ratio (100:0; 70:30; 50:50; 30:70 and 0:100) with glycerol as plasticizer bycasting-evaporation method. The thickness, mechanical properties, water vapor permeabil...

Background: Edible film is a food packaging that can be eaten directly and have protection function of outside contamination. The purpose of this research is to know how about the effect of using a glycerol plasticizer to film whey-konjac edible films that enriched with clove essential oil. Methods: A completely randomized design was used by different clove essential oil including P10, 0% clov...

The effects of three different mixers, two different feeding orders and nanoclay content on the structure development and rheological properties of PE/nanoclay nanocomposite samples were investigated. Fractional Zener and Carreau–Yasuda models were applied to discuss the melt linear viscoelastic properties of the samples. Moreover, scaling law for fractal networks was used to quantify clay disp...
