Following completion of a post-doctorate at CSIRO focused on the development of blood-based biomarkers of colorectal cancer, he was appointed as a CSIRO Research Scientist in 2008 and has continued to develop the scientific knowledge that underpins the health benefits of new food products. Dr. Damien Belobrajdic has produced 43 refereed publications, a patent, and 10 commercial reports for food industry clients. In acknowledgment of his research achievements, he has received awards from the International Association for Cereal Science and Technology, the Australian Academy of Science, the Australian Society for Medical Research, and the Nutrition Society of Australia. In addition, Dr. Damien Belobrajdic is the current Honorable Treasurer for the Nutrition Society of Australia and is on the Complaints Advisory Committee for the Grains and Legumes Nutrition Council (GLNC) and the management committee of the Oceanic Nutrition Leaders Platform (www.onlp.org).

Dr Michael Conlon currently serves as a Principal Research Scientist at CSIRO Health and Biosecurity. He has over 35 years of research experience in areas related to diet and health. Dr Michael Conlon's particular focus has been on the interactions that occur between dietary components such as fibres and proteins, and other components of foods such as polyphenols, and the impacts these have on gut microbes, gut physiology, and health. This research has been applied to a wide range of conditions, including inflammatory bowel disease, colorectal cancer, allergies, and autism, and has involved studying treatment modalities such as probiotics, prebiotics, and faecal transplantation.

Dr. Beverly S Muhlhausler is the Research Director of the Nutrition and Health Program in the Health and Biosecurity Unit at CSIRO. She joined CSIRO in November 2018 after 12 years as an NHMRC Early Career and then Career Development Award Fellow at the University of South Australia and the University of Adelaide. Over this time, her work on the impact of maternal overnutrition on the programming of obesity and metabolic disease has made a significant contribution to the current understanding of how exposure to maternal obesity and/or an excess nutrient supply before birth acts to alter the development of key systems involved in the regulation of energy balance. She has published 120 peer-reviewed papers which have been cited over 3,500 times, as well as 14 invited book chapters, editorials, and commentaries, and presented 24 invited talks at national/international scientific conferences. In addition, Dr. Beverly S Muhlhausler is also a President of the Developmental Origins of Health and Disease (DOHaD) Society of Australia and New Zealand, a Chair of the Scientific Programming Committee for the 2019 DOHaD World Congress, and Treasurer of the International Society for the Study of Fatty Acids and Lipids (ISSFAL).

Abstract
Abstract: The nutritional quality of plant-based meat analogues compared to traditional meat products has been questioned in recent commentary, particularly in relation to protein quality and micronutrient bioavailability. However, the attributes of specific products within this category are unclear. We therefore undertook a comprehensive assessment of the compositional and functional attributes of v2food® (Sydney, Australia) plant-based mince, including an assessment of the effects of reformulation, including the addition of amino acids, ascorbic acid, and different forms of elemental iron. The protein digestibility and protein quality of v2food® plant-based mince were comparable to beef mince in the standardized INFOGEST system, and favourable effects on microbiota composition and short-chain fatty acid (SCFA) production were demonstrated in an in vitro digestion system. The use of ferrous sulphate as an iron source improved in vitro intestinal iron absorption by ~50% in comparison to other forms of iron (p < 0.05), although levels were ~3-fold lower than beef mince, even in the presence of ascorbic acid. In conclusion, the current study identified some favourable nutritional attributes of plant-based v2food® mince, specifically microbiota and SCFA changes, as well as other areas where further reformulation could be considered to further enhance the bioavailability of key nutrients. Further studies to assess the effect of plant-based meat analogues on health measures in vivo will be important to improve knowledge in this area.
