The joint international EUREKA tender of ADEXGO Kft. and Széchenyi István University entitled ” Exploitation of local biodiversity of yeasts for wine production – development of a complex quality testing technology enabling the objective characterization and identification of wines” has ended.
The project was implemented under the leadership of the Romanian company SC ICA Research and Development SRL and with the participation of two other Romanian partners, SC Pharmacorp Innovation SRL and the University of Agronomic Sciences and Veterinary Medicine of Bucharest (USAMVB).
The main goal of the tender, which closed on August 31, 2024, was to develop new, innovative methodologies in the field of winemaking and wine testing. During the 3-year tender period, a methodology was developed that included, in addition to classical testing methods, instrumental rapid analytical technologies, comprising non-destructive near-infrared spectroscopy (NIRS), optoelectronic and gas chromatography (GC) electronic noses, and electronic tongue using ion selective field-effect transistor (ISFET) sensors coated with biological membranes.
Using the developed technology, the individual wine varieties were identified, and the contaminated or infected wines showing taste and smell defects were identified. The developed instrumental rapid testing technology was successfully used to objectively characterize the quality of the experimental wines produced with individual yeast strains and their combinations according to the oenological technology developed by the Romanian consortium partners.
The results proved that the complex methodology incorporating different quality testing protocols into a single system is a useful tool for innovative wine development in addition to human wine tasting and targeted chemical tests. As a result of the project, a complex wine quality testing technology and methodology was developed, which expands the range of services of ADEXGO Kft.’s Correltech division
