Overview

Dr. Éva Várallyay is interested in diagnostic improvement and basic research in plant virology and plant microbiome research. Her group use high-throughput sequencing for virome and metagenome analyses of plant pathogens in grapevine, fruit trees and weeds neighbouring crop fields. Based on her previous experience in RNAi research, they investigate possible antiviral silencing suppressor activity of the recently described uncharacterized viruses and gene-expression changes of the miRNA pattern in the pathogen-infected plants. In their group, they investigate multiple infections of woody plants and the possible virus reservoir role of weeds growing at the edges of crop fields.

Adrienn Varga-Tóth is a researcher specializing in the field of food science and technology. Her scholarly work encompasses three primary areas: livestock product technologies, egg processing technologies, and development of dairy alternatives. Given the growing significance of alternative nutritional diets, her current research is focused on the development and evaluation of dairy alternatives derived from livestock sources. In addition, she oversees the coordination of a research project dedicated to the development and investigation of egg-based food products tailored to specific age groups and health conditions.

She authored and co-authored 60 research articles in high-impact scientific journals (2342 citations: Hirsch index:22) (www.scopus.com/authid/detail.uri?authorId=8559964400).

Projects

2023-1.1.1-PIACI_FÓKUSZ-2024-00035 Kor- és állapotspecifikus funkcionális élelmiszerek fejlesztése az „active ageing”-re fókuszálva / Development of age- and condition-specific functional foods with a focus on active ageing
The project aims to develop new egg white–based, lactose- and milk-protein-free products that meet age- and condition-specific needs (e.g., youth, athletes, older adults, and people in recovery) for adequate protein and essential amino acid intake. It focuses on increasing biological value and improving protein utilization by optimizing the amount and ratio of digestible, bioavailable essential amino acids, which may support faster regeneration and better physical performance. To ensure market success, the products will be tailored for excellent sensory quality, acknowledging that younger and older consumers often have different preferences. The work is carried out by a consortium of Capriovus Ltd. and the Hungarian University of Agriculture and Life Sciences, in collaboration with Semmelweis University’s Faculty of Health Sciences, leveraging Capriovus’s research infrastructure and industrial development expertise. https://palyazatok.uni-mate.hu/web/mate-p%C3%A1ly%C3%A1zatok/2023-1.1.1-PIACI_F%C3%93KUSZ-2024-00035
