In vitro gastrointestinal digestion of polyphenols from different molasses (pekmez) and leather (pestil) varieties Universiteit Gent
In this study, to evaluate the in vitro bioaccessibility of eight different pekmez and pestil samples, total phenolics, flavonoids, proanthocyanidins, anthocyanins and antioxidant capacity were determined at different phases of simulated gastrointestinal (GI) digestion. For the analysis of antioxidant activity, four different methods were used including 2,2-azinobis(3-ethylbenzothiazoline)-6-sulfonic acid, 1,1-diphenyl-2-picrylhydrazil, ferric ...
Anaerobic digestion of molasses by means of a vibrating and non-vibrating submerged anaerobic membrane bioreactor Universiteit Gent
Anaerobic digestion is an environmental key technology in the future bio-based economy that can be applied on a wide diversity of organic substrates for the conversion to methane and CO2. Molasses is an interesting waste stream because of its high organic matter and energy content, yet high salt concentrations might inhibit methanogenesis. In this study, a molasses waste stream was subjected to biomethanation in a submerged anaerobic membrane ...
In vitro models of gut digestion across childhood : current developments, challenges and future trends Universiteit Gent
The human digestion is a multi-step and multi-compartment process essential for human health, at the heart of many issues raised by academics, the medical world and industrials from the food, nutrition and pharma fields. In the first years of life, major dietary changes occur and are concomitant with an evolution of the whole child digestive tract anatomy and physiology, including colonization of gut microbiota. All these phenomena are ...
Effect of gastric pH and bile acids on the survival of Listeria monocytogenes and Salmonella Typhimurium during simulated gastrointestinal digestion Universiteit Gent KU Leuven
The next frontier of the anaerobic digestion microbiome : from ecology to process control Universiteit Gent KU Leuven
The fate of nitrite and nitrate during anaerobic digestion Universiteit Gent KU Leuven
Classical and advanced control methods applied to an anaerobic digestion reactor model Universiteit Gent
In this work, advanced method of process control as Extended Prediction Self-Adaptive Control (EPSAC) and Nonlinear Extended Prediction Self-Adaptive Control (NEPSAC) are implemented and compared with the traditional PID controller tuned by a novel KC autotuning method and a classical FRtool method. The controllers are designed based on a linear and non-linear reactor model of the Anaerobic digestion pilot plant located in Peru. The performance ...
Combined extrusion and alkali pretreatment improves grass storage towards fermentation and anaerobic digestion Universiteit Gent
Grass is an abundant feedstock which is commonly used as animal fodder. It can also be utilized for bio-production, however its availability is generally not consistent through time. Storage is therefore an economic necessity to ensure continuous, steady supply for bioprocessing. Extrusion tests were performed, before or after Ca(OH)(2) addition (75, 100 or 200 g kg(-1) total solid (TS) of grass), with the objective to achieve 3 months ...
