Nutritional Characterization of Sea Bass Processing By-Products

2020

The consumption of functional foods and nutraceuticals is gaining more importance in modern society. The exploration of alternative sources and the utilization of by-products coming from the food industry are gaining more importance. The present study aimed to characterize the nutritional value and potential use of sea bass by-products as a source of high-added-value compounds for the development of supplements. The chemical composition (moisture, protein, fat, and ash contents) and profiles of amino acids (high-performance liquid chromatography coupled to a scanning fluorescence detector), fatty acids (gas chromatography coupled to a flame ionization detector), and minerals (inductively co…

Bioactive Phytochemicals from Grape Seed Oil-Processing By-Products

2022

Winemaking leads to by-products with high added value, which can be used for new productions in different fields. The reuse of grape seed is addressed in the production of oil and related oil-processing by-products. The main residue from seed oil processing is represented by grape seed flour. A focus on grapeseed oil and health by literature quantitative research analysis is presented. Chemical composition, bioactive compounds, and biological and functional properties ofgrape seed oil and oil-processing by-products are described, and databases containing data and information on grape seed by-products are highlighted. Due to their contents of nutrients and bioactive molecules, grape seed oil…

Enhancing Bioactive Antioxidants’ Extraction from “Horchata de Chufa” By-Products

2018

During the production of a traditional drink produced from the tubers of Cyperus esculentus L. also known as “horchata de chufa,” a high quantity of by-products are generated. These by-products are rich with valuable biological compounds, hence, there is a need to report their extraction conditions for further use in food production as raw materials. Therefore, the objective of this study was to evaluate and improve the conventional extraction process, applied for recovery of phenolic compounds, total flavonoids, and total antioxidant capacity from the by-products. Independent variables for extraction were: (i) Solvent type (mixtures of ethanol-water (v/v) at 0%, 25% and 50%)

Environmental management of granite slab production from an industrial ecology standpoint

2014

The granite production chain is high energy and water intensive with low resource efficiency. This paper focus on characterizing the potential for environmental improvement of the granite production chain by promoting the optimization of sawing technology, the implementation of rainwater harvesting (RWH) and the material recovery of wasted granite (sludge). The environmental performance of multi-blade gangsaw (MBGS) and diamond multi-wire saw (DMWS) technologies is compared by mean of life cycle assessment. Results demonstrate that DMWS technology contribute 30% of water savings, 40% of energy savings and 80% of material savings per square meter of polished granite tiles (60 x 40 x 2 cm) pr…

Is female-male mounting functional? An analysis of the temporal patterns of sexual behaviors in Japanese macaques

2019

Abstract In certain populations of Japanese macaques, adult females mount adult males in the context of heterosexual consortships (i.e., temporary but exclusive sexual associations between a male and a female). Previous research suggested that, in this primate species, female-male mounting (FMM) may be a behavioral adaptation. This functional hypothesis holds that FMM is a (special) courtship behaviour, or a (super) sexual solicitation, that serves the function of focusing the male's attention, preventing him from moving away, and expediting male-female mounting, in the context of high female competition for male mates. In this study, we aimed to test some of the proposed functional feature…

Drinking water disinfection by-products during pregnancy and child neuropsychological development in the INMA Spanish cohort study.

2017

Background: Disinfection by-products (DBPs) constitute a complex mixture of prevalent chemicals in drinking water and there is evidence of neurotoxicity for some of them. Objectives: We evaluated the association between estimates of DBP exposure during pregnancy and child neuropsychological outcomes at 1 and 4–5 years of age. Methods: We conducted a population-based mother-child cohort study in Spain with recruitment at first trimester of gestation (INMA Project, 2003–2008). Neuropsychological development was measured at 1 year of age using the Bayley Scales of Infant Development and at 4–5 years with the McCarthy Scales of Children's Abilities. Modeled tap water concentrations of trihalome…

Genotoxic potential of by-products in drinking water in relation to water disinfection: Survey of pre-ozonated and post-chlorinated drinking water by…

2006

Mutagenic potential of drinking water samples derived from ranneywells was studied. 100-100 l of untreated (rough) and ozone-treated as well as chlorinated-disinfected water were dropped on and adsorbed by macroreticular resin columns (Serdolit PAD-III and Amberlite XAD-2). The adsorbed material was desorbed by methanol and dichloromethane. After elimination of the solvents by vacuum distillation the adsorbed material was dissolved in dimethylsulfoxide. The mutagenic activity was tested in the Ames-Salmonella/rat liver microsome system. The tester strains were TA-98 and TA-100. The material adsorbed to Serdolit PAD-III from rough and also disinfected water did not induce mutagenicity in cas…

Gas chromatographic evaluation of pesticide residue contents in nectarines after non-toxic washing treatments

2004

Washing with aqueous solutions of citric acid, ethanol, glycerol, hydrogen peroxide, potassium permanganate, sodium metabisulfite, sodium laurylsulfate (SLS), sodium hypochlorite, and urea is evaluated for pesticide residue reduction in nectarines and compared with simple tap water washing. Residues of pesticides commonly utilized in nectarines (chlorpyrifos, fenarimol, iprodione, malathion, methidathion, myclobutanil, parathion and pirimicarb) are extracted with ethyl acetate and anhydrous sodium sulfate, extract is concentred and analyzed by GC with nitrogen-phosphorus detection. The formation of possible toxic by-products (chlorpyrifos oxon, malaoxon, methidaoxon and paraoxon methyl) is …

Water retention characteristics of substrates containing biochar and compost as peat and perlite replacements for ornamental plant production

2021

In Italy peat and perlite are commonly used as growth substrates in ornamental plant nurseries. Requests for ecologically sustainable growth substrates have recently focused research on the study of new media. In this context, biochar and compost, by-products of other production chains, may play a relevant role. Four growth substrates were prepared by mixing (v/v) different porous matrices including a 2-mm sieved sandy loam soil namely: 50% peat and 50% perlite (PPr), 50% compost and 50% biochar (CB), 25% peat, 25% perlite, 25% compost and 25% biochar (PPrCB) and 25% peat, 25% compost and 50% mineral soil (PCM). Water retention curves of porous matrices and growth substrates were determined…
