Developing Tasty Plant-based Foods: From Extrusion to Plate

Jointly organised by KH Roberts, Leistritz and SIFBI.

Plant-based products have been increasing in popularity among Asian consumers, influenced by their shifting preferences towards ethical, healthy and sustainable consumption. The space is seeing tremendous growth and vibrancy, and major brands, suppliers and food-service outlets are developing plant-based meat innovations. However, one key challenge in consumer adoption is creating a plant-based product that has a delicious and meat-like taste and texture. There are many factors to be considered, from plant sources and ingredients, extrusion processes to crafting meat-like flavour profiles that consumers will enjoy.

In this two-part workshop series jointly organised by KH Roberts, Leistritz and the Singapore Institute of Food and Biotechnology Innovation (SIFBI), we bring together our expertise in scientific research, product development, extrusion process and technology, and aroma and taste masking solutions to create plant-based meat analogues and products that delight Asian consumers.

Raffael Osen, PhD
Group Leader, Food Process Engineering
Singapore Institute of Food & Biotechnology Innovation

Dr Raffael Osen is currently leading the Food Process Engineering Group at SIFBI, A*STAR. Prior to his move to Singapore, he led the department of food process development at Fraunhofer, the largest organisation for applied R&D in Europe. Dr Osen started his research on the development of plant-based meat substitutes in 2010 and obtained his PhD in Food Technology from the Technical University of Munich on high moisture extrusion of plant protein. With his colleagues at Fraunhofer IVV, he provided the scientific and technological framework for meat substitutes from pea protein. In his + 10 years in R&D, Dr Osen has been awarded for numerous competitive research grants and industrial funds in the field of protein extrusion, authored 15 peer-reviewed research papers, one book chapter, three patent applications and was invited to give keynote lectures in major international food-tech conferences. In SIFBI, he is particularly interested in integrating protein ingredients development, texturization and formulation from a wide range of alternative protein sources such as underutilized Asian crops, fermentation-derived proteins and cultivated cells for developing tasty, healthy, sustainable and affordable foods.


Chiang Jie Hong, PhD
Research Fellow, Nutrition
Singapore Institute of Food & Biotechnology Innovation​

Jie Hong graduated with a Bachelor of Food Technology (Honours) and a PhD in Food Technology at Massey University, New Zealand. His PhD thesis was on “The development of extruded meat alternatives using Maillard-reacted beef bone hydrolysate and plant proteins”. Prior to pursuing his postgrad study, he worked as a Research Associate in Food Innovation and Resource Centre (FIRC). His research interests are in looking at the protein-protein interactions to form the structure and texture of meat analogues, flavour development from meat by-products and plant protein sources, and food product developments. He is currently involved in the food structure program in the Clinical Nutrition Research Centre in SIFBI, to develop meat analogues for the Asian markets, and also study protein-polysaccharide interactions for future food applications.
