ANALYSIS OF METHODS FOR ASSESSING THE QUALITY OF HEMP TRUST

Abstract

This work analyzed various methods for assessing the quality of hemp trust: visual-organoleptic, physical-mechanical, chemical, biological, laboratory-analytical and standardized. It was determined that when assessing the quality of hemp trust, special attention is paid to standardized approaches to determining its characteristics, which provide the possibility of harmonizing technologies between countries and contribute to the entry of products into international markets.An analysis of the global and domestic regulatory and methodological framework for determining the quality of hemp raw materials was carried out. Unlike global practice, in Ukraine the regulatory and methodological framework in the field of technical hemp remains fragmented and needs updating. In particular, domestic methods do not take into account the features of new high-yielding varieties of technical hemp, as a result of which there is an imbalance between the trust evaluation criteria and the actual properties of the fiber. Also, the paper describes modern technologies for aging hemp trusts and notes that in Ukraine, the use of outdated technologies for aging industrial hemp stems, in particular traditional field aging, still prevails. This method largely depends on weather conditions – humidity, temperature, duration of precipitation – which complicates control over the uniformity and quality of biodegradation of stem tissues. Uneven aging can lead to the formation of trusts with heterogeneous properties, which negatively affects the quality of the resulting fiber. It is noted that the introduction of modern methods for aging hemp trusts not only increases its quality, but also will reduce the dependence of production on territorial restrictions that arose as a result of the war in Ukraine. The paper provides recommendations for improving domestic methods and implementing modern assessments of hemp trust quality.
