Abstract
U ovom istraživanju je analizirana kvaliteta slada dobivenog iz jarih pivarskih sorti ječma, ključne sirovine za proizvodnju piva. Proučavani su agroklimatski uvjeti, fiziološki razvoj ječma i njegova kemijska kompozicija, tehnološki pokazatelji i procesi proizvodnje piva kako bi se ocijenila kvaliteta dobivenog slada. Rezultati su pokazali da agroklimatski uvjeti i tip tla značajno utječu na agronomske i tehnološke karakteristike ječma, s posebnim fokusom na fenotipski determinirane pokazatelje poput ukupnog i topivog dušika. Varijacije u vlazi slada i apsolutnoj masi zrna također su utvrđene, dok su tehnički parametri poput vremena ošećerenja, filtracije i postotka finog ekstrakta ostali unutar prihvatljivih granica za pivarsku proizvodnju. Sadržaj proteina, topivog dušika te β-glukani i Hartongov broj imaju značajan utjecaj na procese prerade i kvalitetu piva. Važnost optimizacije poljoprivrednih praksi i praćenja agroklimatskih uvjeta izražena je kao ključna za postizanje konzistentne i visoke kakvoće slada za pivarsku industriju. Ova istraživanja pružaju korisne smjernice za daljnje razumijevanje i unapređenje kvalitete slada jarih pivarskih sorti ječma.
Abstract (english)
This study focused on analyzing the quality of malt derived from spring barley varieties, a key ingredient in beer production. Agroclimatic conditions, physiological development of barley, its chemical composition, technological indicators, and beer production processes were investigated to assess the quality of the resulting malt. The results showed that agroclimatic conditions and soil type significantly influence the agronomic and technological characteristics of barley, with a special emphasis on phenotype-determined indicators such as total and soluble nitrogen. Variations in malt moisture and absolute grain weight were also observed, while technical parameters like mashing time, filtration time, and percentage of fine extract remained within acceptable limits for brewing. Protein content, soluble nitrogen, β-glucans, and the Hartong index exerted significant influence on processing and beer quality. The importance of optimizing agricultural practices and monitoring agroclimatic conditions was emphasized as crucial for achieving consistent and high malt quality for the brewing industry. This research provides valuable insights for further understanding and enhancing the quality of malt from spring barley varieties.
