The enormous quantity of food wastes discarded annually forces a look into alternatives for this interesting feedstock.
Agriculture and food industries generate substantial quantities of waste material with a huge potential for bioactive ingredients to be recovered converted into high-value chemicals. Red beetroot, known its high content in betalains, natural red pigments, as well polyphenols, fiber, nitrate, is experiencing increasing demand, particular juice, which leaving behind large amounts waste. The present study focused on the recovery betalains polyphenols from dried whole beetroot wet beet pulp...
The agri-food sector generates substantial quantities of waste material on farm and during the processing these commodities, creating serious social environmental problems. However, wastes can be resources raw for production valuable chemicals with applications in various industrial sectors (e.g., food ingredients, nutraceuticals, bioderived fine chemicals, biofuels etc.). recovery, purification biotransformation phytochemicals from this microbial spoilage-prone, complex material, requires...
The tomato processing industry generates large quantities of peel residues, usually creating environmental problems. These residues are a significant source lycopene, thus providing an attractive alternative for profitable handling these otherwise problematic by-products. enzymatic pretreatment lycopene recovery has already been employed, although the use surfactants enhancing not examined so far. peels, using two commercially available pectinolytic enzyme preparations, was evaluated...
This proof-of-concept study explored the use of an RGB colour sensor to identify different blends vegetable oils in avocado oil. The main aim this work was distinguish oil from its with canola, sunflower, corn, olive, and soybean oils. involved measurements conducted using two light sources: UV (395 nm) white light. Classification methods, such as Linear Discriminant Analysis (LDA) Least Squares Support Vector Machine (LS-SVM), were employed for detecting blends. LS-SVM model exhibited...
The all-trans-β-carotene is a natural pigment used in various industrial fields (food, cosmetics, pharmaceuticals, etc) and possesses the higher provitamin A activity, respect to other carotenoids. All-trans-β-carotene produced industrially by chemical biotechnological means. For β-carotene production scale mated cultures of Blakeslea trispora, heterothallic fungus, are mainly used. Despite intense research for B. substrate utilization has not been extensively studied. Solid agro-food wastes...
In order to characterize and compare the chemical composition of diesel particulate matter ambient air samples collected on filters, different extraction procedures were tested their efficiencies recoveries determined. This study is an evaluation methods using standard 16 EPA PAHs with HPLC fluorescence analysis. Including LC analysis also GC MS for determination can be used. Soxhlet was compared ultrasonic agitation pressurized fluid (PFE) three solvents extract from exhaust urban...
The production of carotenoids from Blakeslea trispora cells in a synthetic medium has been reported, with the main products being beta-carotene, lycopene, and gamma-carotene. effect biomass pretreatment solvent extraction on their selective recovery is reported here. Eight solvents class II III International Conference Harmonization: ethanol, methanol, acetone, 2-propanol, pentane, hexane, ethyl acetate, ether, HPLC analysis were used for evaluation selectivities towards three regard to...
The phenomenon of autolysis in Blakeslea trispora during carotene production from deproteinized hydrolyzed whey an airlift reactor was investigated. process cellular studied by measuring the changes concentration, dry biomass, residual sugars, pH, intracellular protein, specific activity hydrolytic enzymes (proteases, chitinase), and micromorphology fungus using a computerized image analysis system. All these parameters were useful indicators autolysis, but found to be most indicator onset...
BACKGROUND Table olive processing wastewater (TOPW) is a seriously polluting and difficult to treat effluent, characterized by widely fluctuating pH salinity, as well high concentrations of organic matter polyphenols. This systematic long-term study in laboratory-scale pilot demonstrates that membrane bioreactor (MBR) technology effective substantially bio-degrading TOPW. RESULTS After implementation an appropriate protocol active biomass acclimatization/proliferation, the MBR was operated...
Tomato leaves have been shown to contain significant amounts of important metabolites involved in protection against abiotic and biotic stress and/or possessing therapeutic properties. In this work, a systematic study was carried out evaluate the potential sustainable process for fractionation major biomolecules from tomato leaves, by combining aqueous extraction membrane processes. The parameters (temperature, pH, liquid/solid ratio (L/S)) were optimized obtain high (proteins,...
