Effect of a natural polyphenolic extract on the properties of a biodegradable starch-based polymer

Corn starch systems as carriers for yerba mate (Ilex paraguariensis) antioxidants

“…The decrease in enthalpy could be associated to a plasticizing effect of yerba mate extract polyphenols on starches. In a similar way, Cerruti et al (2011) found that a polyphenol-containing extract derived from winery waste, used as a natural additive, exerted a plasticizing effect on Mater-Bi ® (grade CF03A, Novamont, Italy), a starch-based polymer.…”

Enhancement of poly(3-hydroxybutyrate) thermal and processing stability using a bio-waste derived additive

“…The scientific literature reports a number of studies dealing with the evaluation of the upgrading effects of these natural substances when added to polymeric matrices as antioxidants [31,32,35] processing aids [36], and plasticizers [37,38]. In particular, a grape pomace extract (EP) was found to be very effective in delaying thermal oxidative degradation of polypropylene [31] and in improving the processability and thermal stability of a biodegradable starchbased polymer [36].…”

Valorization of winery and oil mill wastes by microbial technologies

“…The incorporation of different processes defined in this review will certainly have a positive effect on the scientific, technological, economic, environmental, and social points of view, not only for the main production but also for a wide range of co-products generated from wine and oil industries including composting (Bustamante et al, 2014), biofuels (Georgieva & Ahring, 2007), chemicals (Apohan & Yesilada, 2011;Romero et al, 2007;Abrunhosa et al, 2013), biomass itself (Masghouni & Hassairi, 2000) and other compounds (Cerruti et al, 2011;Crognale et al, 2006;Gomes et al, 2013;Santos et al, 2008). The economic and technological aspects of the processes should be enhanced to offer a realistic approach to valorization of winery and olive oil mill by-products.…”

“…OMW were diluted at different concentrations as the sole carbon source to produce polyhydroxyalkanoates, and in parallel, to contribute efficiently to the bioremediation of this waste. A polyphenol-containing extract from winery waste has also been used as an additive for a starch-based polymer, thus avoiding the use of synthetic polymer compounds (Cerruti et al, 2011).…”
