SPECIFIC RESEARCH OBJECTIVE 1: 
Gain insight into the effects of different processing techniques of alternative protein sources on their techno-functional properties. More specifically, the impact of processing techniques on properties especially relevant for meat analogues and hybrid meat products will be investigated; thermal protein stability, protein solubility, water holding capacity, viscosity, and emulsifying and gelling properties. In addition, the structuring of protein will be studied from the molecular, over microstructural up to macrostructural level.

SPECIFIC RESEARCH OBJECTIVE 2: 
Gain insight into the effects of different processing techniques of alternative protein sources on their nutritional quality. More specifically, the effect of processing techniques on the contents of essential nutrients (AAs, minerals, vitamins), and various ANFs will be investigated. Today, it is known that nutritional quality evaluation should go beyond measuring compound concentrations only. Also, the fate of nutrients within the digestive tract is of major importance. In this work, the digestive hydrolysis pattern of proteins during in vitro digestion will be simulated. Since meat is an excellent source of various B-vitamins and minerals (Fe, Zn, Se, P), a comparison of the absorption of these specific compounds into the bloodstream will be made, following consumption of 100% meat versus various hybrid meat products using a pig model. In addition, the effect of processing on allergenicity of pea protein will be investigated.

SPECIFIC RESEARCH OBJECTIVE 3: 
Gain insight into the effects of different processing techniques of alternative protein sources on their oxidative stability. Initially, an UHPLC method for the analysis of specific protein oxidation products will be optimized. By using this optimized UHPLC-method, in addition to more commonly described markers for protein oxidation (thiols, protein carbonyls), protein oxidative stability will be assessed during processing of alternative protein sources as well as during simulated GI digestion.

SPECIFIC RESEARCH OBJECTIVE 4: 
Gain insight into how different processing techniques of alternative protein sources impact human health. Diet impacts human health through many different pathways. This project will focus on the effects of alternative protein processing techniques on several aspects of intestinal health.
