ECONOMICALLY PROFITABLE NOVEL QUALITY EVALUATION METHOD FOR RAW HOP (HUMULUS LUPULUS L.)
Journal Title: Біоресурси і природокористування [Biological Resources and Nature Management] - Year 2018, Vol 10, Issue 3
Abstract
Based on years of research the technology of determining the raw hops quality on the results of morphological and structural indices of lupulin glands of hop cones study has been proposed. Several variants of the methodology have been developed based on scanning electron, luminescent and light microscopy. All fragments of the technique have conductometa significantly lower cost and a simpler algorithm compared to commonly accepted European methods for determining the quality of raw hops, namely the content of the bitter substances and the main component - α-acid. The hop`s Carlavirus, which has a considerable spread on hop plantations, caused a significant reduction in the quality of raw materials of this valuable crop, was used in the work as a model system. The proposed technique can be applied (with simple microscopy) in field conditions on different hop types; for express evaluation of raw materials at customs; for evaluation of lupulin at brewery and pharmaceutical, food, cosmetic, special laboratories; for analysis of lupulin after treatment of hops with preparations of various composition.
