Anaerobic digestion is a promising method of organic waste valorisation, particularly for fish farm waste, which has experienced high growth rate in recent years. The literature contains predictive mathematical models that have been developed by various authors, allowing the prediction composition bio-gas production from waste. In general, Monod’s kinetic expression basis describing enzymatic r...

Functional food emulsions enriched in health-promoting nutrients can help to maintain and improve health lifestyle. The oil extracted from the Amazonian buriti fruit is renowned for its high levels of carotenoid, vitamin E, unsaturated fatty acids, which have been linked improvements cardiometabolic health. Here, water are developed their colloidal transformations investigated an advanced diges...

In this research, biochar (BC) made from the brewer’s spent grain at temperatures of 300, 450, and 600 °C was produced subjected to anaerobic digestion grain. BC shares 2, 5, 10, 50% concerning total solids substrate were tested three substrate-to-inoculum ratios 0.5, 1.0, 2.0, respectively. The process performed 37 took 30 days. For digestion, biomethane production recorded used for kinetics p...

The present study sought to understand how the microstructure of protein gels impacts lipolysis of gelled emulsions. The selected system consisted of an oil-in-water (o/w) emulsion embedded within gelatin gels. The gelatin-gelled emulsions consisted of a discontinuous network of aggregated emulsion droplets (mesoscale), dispersed within a continuous network of gelatin (microscale). The viscoela...

The present study sought to understand how the structure of protein gels impacts lipolysis of gelled emulsions. The selected system consisted of an o/w emulsion embedded within gelatine gels. The gelatine gelled emulsions consisted of a discontinuous network of aggregated emulsion droplets, dispersed within a continuous network of gelatine. The rheology of the gelled emulsions was dominated by ...

The impact was studied of buffer pH (5.8, 6.2, and 6.8) on in vitro digestion kinetics of NDF from alfalfa hay, bromegrass hay, corn silage, and alfalfa and bromegrass hays with raw corn starch added to approximate a ration containing 30% NDF. Ash-free NDF was determined at 0, 6, 12, 18, 24, 30, 36, 48, 72, and 96 h of fermentation. Kinetic parameters were estimated by nonlinear regression usin...

Knowledge of digestion kinetics of solid foods in human stomach, as affected by food processing methods, is critical in establishing processing conditions at the manufacturing stage to achieve desirable release of nutrients in the gastrointestinal tract. The objective of this study was to investigate how roasting affected disintegration and solid release properties of almond in simulated gastri...

VIII Abstract Anaerobic digestion of energy crops for biogas production has attracted much interest in recent years. In Germany, the most common process is the continuous wet-fermentation of energy crops with cattle slurry or pig slurry (co-digestion). But also the digestion of energy crops as single substrate without slurry (mono-digestion) becomes more important. Because of the great diversit...

The digestion kinetics of a variety of pure celluloses were examined by using an in vitro assay employing mixed ruminal microflora and a modified detergent extraction procedure to recover residual cellulose. Digestion of all of the celluloses was described by a discontinuous first-order rate equation to yield digestion rate constants and discrete lag times. These kinetic parameters were compare...

The objective of the present study was to develop a mathematical model of pathogenic bacterial inactivation kinetics in a gastric environment in order to further understand a part of the infectious dose-response mechanism. The major bacterial pathogens Listeria monocytogenes, Escherichia coli O157:H7, and Salmonella spp. were examined by using simulated gastric fluid adjusted to various pH valu...
