DESCRIPTION:Protein Digestion in the Context of Personalized Nutrition: Ana
 lytical Evaluations of the Effects of Age\, Sex\, and Food Structure on th
 e Digestibility of Animal- and Plant-Based Proteins\nAbstract: ** Lecture 
 will be given in English**\nIn face of a fourth food revolution in human e
 volution\, protein quality is increasingly recognized as a determinant tow
 ards possible personalized nutritional solutions. This research investigat
 ed how age\, sex\, and food matrix characteristics shape protein digestibi
 lity and amino acid bioaccessibility\, while developing evidence-based fun
 ctional foods tailored to vulnerable populations. First\, a plant-based fu
 nctional co-extruded breakfast cereal designed for older adults (12.75% pr
 otein\, ~17% fiber) was developed based on flour blends (teff\, chickpea\,
  rice\, and maize) and a tahini-based filling enriched with bioactive comp
 ounds. The formulation exhibited good palatability in a tasting panel and 
 achieved &gt\;80% protein in vitro digestibility under a senior-adapted se
 mi-dynamic in vitro digestion model. Next\, the differential digestibility
  of milk and an oat-based alternative were studied under male and female d
 igestive conditions. Proteomic analyses of digesta revealed differential t
 rends in the bioaccessibility of bioactive peptides and amino acids.\nLast
 \, six protein sources from animal (milk\, egg\, collagen) and plant (soy\
 , pea\, oat) origins were evaluated across male\, female\, and elderly dig
 estion models. This enabled coupling in vitro digestion models with LC-MS/
 MS free amino acid profiling\, OPA spectrophotometry\, pH-stat and pH-drop
  kinetics\, towards integrative and comparative multivariate PCA analysis 
 of protein quality metrics. Collectively\, this work challenges the tradit
 ional “one-size-fits-all” paradigm of protein digestion research and r
 eframes it into a triage of host physiology\, food structure\, and protein
  quality. Thus\, the work offers both new tools for food digestion researc
 h as well as design principles for the development of next-generation func
 tional foods tailored to specific demographic groups.
