“…The density values of SFE‐10 containing 0–10 wt% OEO were in the range of 0.26–0.34 g/cm 3 . The obtained density values were similar to those of starch foam composites incorporated essential oil, bee wax, and palm oil . From Table , the density of samples increased with increasing OEO content due to the reduction of foam expansion.…”

Bioactive Starch Foam Composite Enriched With Natural Antioxidants from Spent Coffee Ground and Essential Oil

et al. 2018

Starch foam composites containing extracted spent coffee ground and 10 wt% of spent coffee ground (SFE‐10) are prepared by compression molding. Four to ten weight percent of oregano essential oil (OEO) is added to the SFE‐10. Characterization by ATR‐FTIR and total phenolic assay confirms that bioactive compounds of OEO, spent coffee ground (SCG), and extracted spent coffee ground (ex‐SCG) penetrate into the samples. The minimum inhibitory concentration against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) is investigated in SFE‐10 incorporated 8 wt% OEO. Synergism in antibacterial activity is also achieved from the starch foam incorporated combination of OEO, SCG, and ex‐SCG. The kinetics of polyphenol release in food simulants are observed, and the release rate increases when the polarity of aqueous simulants decreased. The water resistance of the samples improves with increasing OEO content, whereas the biodegradability and flexural strength slightly decrease. Based on the results, SFE‐10 containing OEO has a good potential for application as a bioactive packaging to preserve and maintain the quality of food.

“…Figure (a) showed ATR‐FTIR spectra of OEO, SCG, and starch. The FTIR spectrum of starch showed the board band at 3300 and 2930 cm −1 which were related to OH stretching and CH stretching, respectively . The peaks at 1637 and 1423 cm −1 were attributed to the bending of water and CH 2 stretching, respectively.…”

“…An absorption band from 3000 to 3500 cm −1 was observed in the cassava starch spectrum, with higher intensity than in the broken rice spectrum. This band can correspond to the complex vibrational stretching associated with free, inter‐, and intra‐molecularly bonded hydroxyl groups between neighboring molecules of starch . The cassava starch spectrum shows a peak at 2921 cm −1 , which can be associated with CH stretching .…”

Effect of Broken Rice Flour Addition on Cassava Starch‐Based Foams

et al. 2018

View full text Add to dashboard Cite

Large amounts of waste generated by the disposal of non-biodegradable packaging is a major concern that has stimulated the search for new materials for the development of environmentally friendly packaging. This study aims to produce cassava starch-based foams incorporated with broken rice, a co-product of rice milling. Foams were obtained by a thermopressing process, and the influence of broken rice concentration on the formulations is investigated. Broken rice addition is tested for 0 (control sample), 10, 15, 20, and 30% (w/w). Foams containing broken rice show lower thickness and higher density. With respect to water absorption capacity, the control foam and those with 10 and 15% (w/w) of broken rice addition do not present significant statistical differences for any of the tested times. Mechanical properties (tensile strain and maximum flexural stress) are positively influenced by the addition of 10% (w/w) broken rice. Foams made from formulations containing 10% (w/w) broken rice demonstrate higher tensile strain and maximum flexural stress values compared to control foams. Additionally, these foams exhibit a good appearance without superficial cracks.

“…Moreover, most small sized fillers are expensive and results in a high cost for the final product. To obtain a cheaper product, wastes from agriculture and industry have been used as a filler for TPS such as eggshells , bagasse , husks , and straw . Moreover, these fillers require low amounts of energy for production.…”

Green composites based on thermoplastic starch and rubber wood sawdust

et al. 2015

Rubber wood sawdust (RS) was used as a filler to improve the water absorption, mechanical, morphological, and thermal properties of thermoplastic starch (TPS). The TPS/RS composites were prepared using compression molding and glycerol as the plasticizer. Moreover, the effect of commercial cellulose (CC) on the properties of TPS was also studied for comparison. Scanning election microscopy, thermal gravimetric analysis, and Fourier transform infrared spectroscopy were used to confirm that there were lignin, hemicelluloses, and extractive compounds such as wax substances and natural oils on the surface of rubber wood sawdust. Both fillers showed good adhesion with the TPS because they have similar chemical structures. However, RS showed the better efficiency for improve the water absorption, mechanical, and thermal properties of TPS than CC. The results indicated that the components on the fiber surface play important roles in improving the properties of TPS. POLYM. COMPOS., 38:1063–1069, 2017. © 2015 Society of Plastics Engineers
