Abstract
Porast svjetske populacije iziskuje i veću potražnju za proteinima, a pogače dobivene nakon ekstrakcije ulja predstavljaju dobar izvor proteina. Sjeme industrijske konoplje (Cannabis sativa L.) izvor je visokokvalitetnog ulja koje sadrži preporučeni omjer omega-6 i omega-3 esencijalnih masnih kiselina te je i izvor proteina bogatih esencijalnim aminokiselinama. Cilj ovoga rada bio je istražiti utjecaj predpriprema (način mljevenja, prosijavanje, tretiranje ultrazvukom visokog intenziteta) te različitih parametara kiselinsko–bazne ekstrakcije (vrijeme ekstrakcije, omjer vode i pogače, utjecaj soli i pH) na količinu i čistoću dobivenog proteinskog izolata iz nusprodukta proizvodnje konopljinog ulja - pogače. Iz dobivenih rezultata, prosijavanje se pokazalo kao značajna metoda predpripreme. Kriogenim mljevenjem dobiveno je 3,18 g izolata (12,72%) s niskim udjelom proteina (48,47%). Najbolji rezultati su dobiveni pri vremenu ekstrakcije od 60 min i omjeru pogače i deionizirane vode 1:20. Primjenom pH 12 dobiva se najviše proteinskog izolata (7,9g – 31,60%) najvećeg udjela proteina (73,38%).
Abstract (english)
The increase of world population is also increasing demand for protein, and the cakes obtained after oil extraction are a good source of protein. Industrial hemp seeds (Cannabis sativa L.) are source of high quality oil that contains the recommended ratio of omega-6 and omega-3 essential fatty acids and it is also source of protein, meaning they are rich with essential amino acids. The aim of this study was to investigate the influence of pre-preparations (grinding method, sieving, high-intensity ultrasound treatment) and different parameters of acid-base extraction (extraction time, water-to-cake ratio, salt and pH) on the received amount and purity of protein isolate obtained from hemp oil by-product – press cake. From the obtained results, sieving proved to be a significant method for pre-preparation. Cryogenic milling yielded 3.18 g of protein isolate (12.72%) but with a low protein content (48.47%). The best results were obtained with extraction time of 60 min and water-to-cake ratio at 1:20. Applying pH 12 gives the highest protein isolate (7.9g – 31.60%) with the highest protein content (73.38%).
