Strategic choices for in vitro food digestion methodologies enabling food digestion design KU Leuven
Background: In the past decades, the great interest in food digestion research led to a wide array of in vitro digestion (IVD) methods. Each of these methods have the potential of providing specific valuable scientific in- sights in digestion mechanisms and the rational structural design of foods. Scope and approach: This review paper outlines important transitions in recent IVD research and formulates important considerations relevant for the ...
From single to multiresponse modelling of food digestion kinetics: The case of lipid digestion KU Leuven
This work presents that lipid digestion kinetics of oil-in-water emulsions can be described by a mechanism-based multiresponse model. The modelling approach proposed takes into account multiple interlinked responses of in vitro lipolysis. Different reaction schemes are proposed and iteratively adapted for one dataset. Based on model discrimination, the model that best described the experimental data was selected. This selected multiresponse ...
Comparative digestion of thermally treated vertebrates and invertebrates allergen pairs in real food matrix Ghent University
The digestion stability of allergen pairs, tropomyosin, TM (fish and seafood allergen), and myosin light chain, MLC (chicken meat allergen) is compared among vertebrates and invertebrates in raw and cooked food matrix under standardized simulated in vitro gastrointestinal (GI) digestion. SDS-PAGE followed by multiple TM and MLC-specific antibodies in semidry WB revealed pepsin resistance of invertebrate TMs (abalone, oyster, shrimp) under ...
Peptidergic control of food intake and digestion in insects University of Antwerp KU Leuven
Like all heterotrophic organisms, insects require a strict control of food intake and efficient digestion of food into nutrients to maintain homeostasis and to fulfill physiological tasks. Feeding and digestion are steered by both external and internal signals that are transduced by a multitude of regulatory factors, delivered either by neurons innervating the gut or mouthparts, or by midgut endocrine cells. The present review gives an overview ...
Does gastrointestinal digestion affect low level thiouracil residues upon Brassicaceae derived food and feed consumption? Ghent University
In recent years, endogenous formation of thiouracil (TU) has been reported in the urine of livestock upon consumption of glucosinolate-rich crops, belonging to the Brassicaceae (Pinel et al., 2006). This has been a staggering discovery, since the European Union in 1981 banned the use of thyreostatic drugs for fattening purposes in livestock. Previously, TU has been demonstrated in various Brassicaceae-derived foods and feeds (<1.0 µg kg-1 - ...
Revolutionizing sanitation: Valorizing fecal slags through co-digesting food waste at high-solid content and dosing metallic nanomaterials for anaerobic digestion stability KU Leuven
To achieve the UN Sustainable Development Goals (SDGs) and the China Toilet Revolution on a global scale, it is crucial to implement a decentralized sanitation management system in developing countries. Fecal slags (FS) generated from septic tanks of toilets pose a challenge for remote villages. This study sought to resourcefully utilize FS through co-digesting with food waste (FW) under high-solid anaerobic co-digestion (HSAD). Besides, two ...
Effect of food structure and buffering capacity on pathogen survival during in vitro digestion KU Leuven
Even though a plethora of barriers are employed by the human gastrointestinal tract (GIT) to cope with invading pathogens, foodborne diseases are still a common problem. The survival of food pathogens in the GIT is known to depend on food carrier properties. The aim of this study was to investigate the influence of food buffering capacity and food structure on the survival of Salmonella Typhimurium and Listeria monocytogenes during simulated ...
