5th Annual Research Spotlight Agenda

Speakers

Stephan Drusch, Professor, Technische Universität Berlin

Stephan Drusch

Keynote Speaker

Biography

Dr. Stephan Drusch is Professor for Food Technology and Food Material Science at Technische Universität Berlin. He studied at the University of Kiel (Diploma, PhD) and worked as a researcher in the dairy industry, at the University of Kiel, Germany, and the University of Milan, Italy. He is member of the scientific advisory board of the Research Association of the German Food Industry (FEI) and the Federal Ministry of Food and Agriculture. His research activities focus on structure-function relationships in food processing with emphasis on dispersed systems and the encapsulation of food ingredients.

Presentation: Challenges and opportunities for plant proteins from agri-food side streams

There are multiple high protein side streams in food processing, which are not efficiently utilized yet. Presence of undesirable minor constituents, sensory aspects and structural modification of the proteins during processing and are among the challenges, when setting up a strategy for their recovery and use as food ingredient. Furthermore, the protein fraction inherently represents a heterogeneous mixture of individual proteins with varying techno-functional potential. The presentation will focus on these aspects using canola protein as an example to unravel the interplay between protein composition, structure and functionality in dispersed systems.

Presenting: A novel approach to plant protein processing by high pressure structuring

Increased utilization of pulses can benefit the environment and global food security, but challenges related to texture and taste of pulse products need to be overcome to increase their consumer acceptance and utilization. This presentation will discuss the effects of high pressure processing (HPP) on pulse protein concentrates, including a comparison with heat treatment. HPP and heat treatment denature pulse proteins and increase their surface hydrophobicity, which at high protein concentration facilitates the formation of strong gels with high water holding capacity. These gels' structure and texture can be further modulated by acidification and calcium addition. These results can help guide new product formulation of high-protein food applications using pulse protein ingredients.

Presenting: Tasty but Slippery: Liquid Oil Feeds and their Impact on High-Moisture Extrusion Processing

The incorporation of lipids in the extrusion process to produce composite protein-lipid high-moisture meat alternatives is a major challenge due to slip conditions induced by the oil phase. Lipids are, however, an integral part of the eating experience and deliver important nutritional and sensory attributes such as mouthfeel, flavor, and vitamins. Overcoming the 'lipid bottleneck' in high-moisture extrusion processing would ultimately enable the design of novel product categories, such as marbled plant-based meats. In this talk, I will discuss potential solutions to overcome the introduced slip conditions when oil is used in the liquid feed. The focus of the talk will be on the effect of emulsified feeds on the processing and textural properties of a high-moisture meat alternative.

Presenting: Plant proteins are a foe or a friend? Extraction and modification remedies

The demand for plant-based, novel, and sustainably sourced protein ingredients is steep. While plant protein is gaining traction, functionality limitations is hindering their market growth. Improving plant protein functionality will enable successful utilization in various food applications. This presentation will demonstrate enhancement in plant protein functionality through a combination of controlled extraction and modification approaches. There is not one size that fits all. Because each protein source is unique, specific upstream and downstream processes will result in targeted enhancement in functionality. Different plant protein sources (e.g. hemp, pea, chickpea, and pennycress) will be featured along with specific extraction and modification strategies that resulted in marked enhancement in either solubility or gelation properties.

Presenting: Fine-Tuning Sustainable Extraction Processes for Enhanced Protein Functionality and Process Feasibility

The growing demand for plant protein ingredients has prompted the need for feasible and functionality-driven protein extraction approaches. Therefore, a deeper understanding of the impact of key processing steps (e.g., extraction, fractionation, post-extraction modifications) on protein yields and costs, which describes the effectiveness of the process, and their functional properties (e.g., solubility, foaming, and emulsifying properties), which will determine their potential applications in food products, becomes imperative.  Importantly, the nutritional and biological properties of the extracted protein, such as amino acid composition, digestibility, and allergenicity, are key aspects that should not be overlooked during the development of extraction and isolation methods of proteins for food, feed, and nutraceutical applications. In this talk, I will describe how aqueous and enzymatic extraction of plant-based proteins can be tailored to promote structural and physicochemical modifications that enhance specific protein functional properties, extractability, and process feasibility. Additional benefits of proteolysis, such as enhanced protein digestibility and reduced allergenicity, will also be discussed.

Presenting: Influence of Animal and Plant Protein Isolates on the Human Gut Microbiota Under High and Low Carbohydrate Conditions

There is a lack of research comparing how proteins and dietary fibers interact to influence the microbiome. This presentation reports changes in gut microbiota composition and function during fermentation of digested protein isolates from beef, egg white, milk, pea, and soy, under high and low dietary fiber conditions. Under low fiber conditions, the microbiota was primarily proteolytic with decreased concentrations of peptides and increased variance among microbial taxa and production of protein fermentation metabolites. Milk protein resulted in the highest production of butyrate and p-hydroxyphenylacetate, but also had high concentrations of deleterious fermentation metabolites. Amino acid composition of the protein isolates was significantly correlated with abundances of many microbial taxa and metabolites, but the correlations were stronger under low fiber conditions. This study suggests that under low fiber conditions, microbiota composition and function may be more influenced by dietary proteins than by dietary fiber.

Presenting: Electrostatically enriched plant proteins and their application in 3D food printing

Tribo-electrostatic separation (TES) is a waste-free approach to dry-fractionating milled legumes, cereals, and oilseed meals, producing functional protein concentrates. Through TES, milled particles of agro-materials are charged using tribo-charger tubes of different materials through pneumatic transfer and fractionated under an electric field. The uniform particle size distribution of dietary fiber and protein particles restricted the protein enrichment in cereal groats and oilseeds compared to legumes. The TES analysis on binary mixtures of protein-starch and protein-fiber showed that the initial protein content plays a crucial role in high protein enrichment. Enriched legume proteins exhibited superior rheological and viscoelastic properties as 3D printing materials for healthy snacks.

Presenting: Towards scalable processes for culturing meat 

The rapidly developing field of cellular agriculture—which addresses the challenge of growing muscle tissue ex vivo by harvesting precursor cells from animals and culturing them in a bioreactor—has exciting potential to provide a sustainable alternative method for meat production with reduced environmental impact. However, innovations in production efficiency will be key for scaleup. My group recently developed edible microcarrier scaffolds that have tunable mechanics—which can mimic the natural growth environment of muscle and fat cells—and are compatible with suspension culture.  I will show how we can customize scaffold physical properties to support the growth of both myogenic and adipogenic microtissues. Our work also demonstrates how scaffolds provide the foundation for structuring and organizing the growth of both myogenic and adipogenic cells and microtissues.
