| Evaluation of Sprayed with Ozonated Water Spring Barley (Hordeum vulgare L.) Grain Quality by Chemical and Holistic Methods Daiva Sileikiene1; 1VYTAUTAS MAGNUS UNIVERSITY, Kaunas, Lithuania; PAPER: 85/AdvancedMaterials/Regular (Oral) SCHEDULED: 14:50/Wed. 30 Nov. 2022/Saitong ABSTRACT: <p>Research objects used herein are chemical and holistic test methods for spring barley and ozonated grain. The aim of this research project is to (1) analyze the influence of ozone-saturated water spray on chemical and electrochemical parameters of spring barley grain, (2) determine the electrochemical characteristics of barley grain grown by spraying with ozone and water by seasonality, (3) evaluate the electrochemical parameters of barley grain according to the applied technologies, and (4) analyze the possibilities of applying the method of biocrystallization for the quality of spring barley grain. Methods used include identification of chemical and electrochemical parameters, biocrystallization, and analysis of numerical values of independent evaluators. After the evaluation of spring barley cultivated using ozone-sprayed water, no statistically reliable effect of ozonated water on grain quality was established. Spraying with more water (plain and ozonized) shows a downward trend in numerical values of absolute redox potential. The lowest energy P numerical values were calculated for barley grain, which was sprayed with water 4 times. Biocrystallization method for barley grain quality requires further preparation of the methodology.</p> References: <p>1. Glowacz, M., & Rees, D. (2016).
