“…For example, biodiesel production wastes have been transformed into commodities, using as catalysts materials from the same company´s residues (Yates et al, 2014), citrus wastes have been catalytically transformed into p-cymene, pharmaceutical and fine chemical intermediates, avoiding the need for petroleum derivatives that are currently used at the industrial scale on commercial catalysts (Martin-Luengo et al, 2008) and on Spanish clays based catalysts (Martin-Luengo et al, 2010), rice production wastes have been used in the design of structured materials to decontaminate effluents (Martin-Luengo et al, 2012), act as support for catalysts (Martin-Luengo et al, 2011) and enzymes (Martin-Luengo et al, 2013), sunflower production residues have been transformed into multifunctional materials (Martin-Luengo et al, 2011c) and catalysts for the same industry use (Yates et al, 2014) and beer production wastes have been transformed into powdered materials (Yates et al, 2008), scaffolds for hard tissue engineering (Saez Rojo et al, 2014) and supports for controlled desorption of bioactive substances (Martinez Serrano et al, 2015).…”

The work presented here uses apple pomace (AP), an industrial waste from apple juice and cider production as a renewable raw material (RRM), to obtain materials that can be utilized as biocompatible scaffolds for osteoblasts and chondrocytes, employed in tissue engineering, valuable extracts that can be used as nutraceuticals and pectin. All of these have much higher value than the original raw material, pectin can be priced up to 1 euro/g, chlorogenic acid is ca. 120 euros/g, caffeic acid 3-5 euros/g and especially the scaffolds that are usually made by synthetic methods using non-renewable raw materials with high fabrication costs and sold at prices higher than 100 euros/g, while the residues used here have prices lower than 100 euros per ton. Thus, there are clear environmental and financial incentives in transforming this waste material into valuable substances and materials. As indicated in the Graphical Abstract, the procedure followed consists in sequential extractions of antioxidants, pectin and finally the preparation of a biocompatible material, giving priority to the latter due to its importance as a renewable scaffold for tissue engineering. From a literature search, to date, although separate ways of valorisation have been applied to this kind of waste, the sequential multivalorization adopted here, has not been previously attempted. Furthermore, biocompatible scaffolds from AP have not been described.

“…Rice husk (RH) from DACSA (Spain) [12] is an agriresidue from rice production, of difficult storage and transport due to its high volume to weight ratio. On calcining this residue, a material with more than 97% silica is produced, that has also low amounts of calcium and potassium [13][14][15].…”

“…Therefore, they can be found in agroindustrial by-products from fruit and vegetable industries too. Moreover, the revalorization of food by-products can avoid the economic and environmental cost that they generate to producers [9] and contributing to the requirements of European Union [10].…”

Antimicrobial Capacity of a Cauliflower By-Product Infusion Combined with the PEF Treatment against S. Typhimurium

et al. 2016

Abstract-Salmonella spp is a foodborne pathogen related with food outbreaks worldwide. To control it, new strategies have been developed to preserve food products, such as the application of non-thermal treatments like pulsed electric fields (PEF) or the addition of antimicrobial compounds from vegetable by-products. The main objective of this study is to evaluate the antimicrobial effect of PEF treatment, combined with several concentrations of cauliflower by-product infusion against S. Typhimurium.Survival curves of S. Typhimurium, treated and nontreated by PEF, were obtained during their incubation under different cauliflower by-product infusion concentrations (1%, 5%, 10%) at 37 °C. The control sample was incubated with buffered peptone water (0.1%). PEF treatment (20 kV/cm -900 µs) reduced 4,5 log cycles of the initial microbial population (10 8 cfu/mL). Also, both in PEF treated and nontreated samples, cauliflower by-product concentrations of 5% and 10% exerted a bactericidal effect against S. Typhimurium, although the time necessary for total inactivation was shorter when combined with PEF (2 hours) than non-PEF treated samples (8 hours).The results obtained were fitted to a Weibull distribution function, and its kinetic parameters (b and n) were obtained. Both in PEF treated and non-treated samples, b values, which are related with the inactivation rates, were higher when the cauliflower by-product infusion concentration was greater. Also, the b values of PEF treated samples were higher than the b values of non-treated samples. Therefore, the PEF treatment combined with the addition of cauliflower by-product infusion exerted a higher antimicrobial effect against S. Typhimurium than when they were applied separately.In conclusion, PEF treatment combined with the addition of 5 or 10% of cauliflower by-product infusion could be used as a S. Typhimurium control measure in liquid food products in the future.
