Визначення впливу вологості обрушених ядер насіння конопель на показники якості зберігання

The object of research is the regularities of the process of storing dehulled seeds of industrial hemp, seed moisture, storage packaging, structure of dehulled hemp kernels. The effect of the moisture content of the kernels of industrial hemp seeds of the “Glesia” variety on their storage period was studied. It was noted that hemp seeds are a source of easily digestible vegetable protein and contain a wide range of phytonutrients important for the health of cells, blood vessels and internal organs of a person. The kernels of industrial hemp seeds are a ready-to-use product. The shelling of seeds (separation of the shell from the kernel) was carried out mechanically by a centrifugal sheller of our own design. The diameter of the sheller impeller was 162 mm, the gap between the impeller and the reflecting deck was 80 mm, the impeller rotation speed was 2000 min-1. The influence of humidity (21.6%, 16.3%, 12.0% and 8.8%) of hemp seeds on the storage period and quality indicators of kernels obtained from it was studied. Whole and crushed kernels without husks were stored in polyethylene bags without access of air from May to August under normal room conditions. It was found that kernels with a humidity of 21.6% became unusable after 15 days of storage due to the appearance of visible traces of mold. On the 30th day of storage, the mass in the bag turned into a white homogeneous mixture. It was noted that a whole kernel with increased humidity deteriorates faster compared to crushed ones. It was found that kernels with a seed humidity of 16.3% did not have visible signs of mold growth on the 15th day. However, mold was found in the bags on the 30th day of storage. In packages with whole kernels, it is more actively developed, and in packages with crushed kernels – insignificant traces. At seed moisture content of 12.0% and 8.8% after three months of storage, the packages with kernels remained unchanged. Visually, no visible signs of the appearance and reproduction of mold were found in these packages. Logistic dependencies of the probability of kernel suitability for consumption have been established depending on seed moisture, storage duration, and kernel structure. The importance of controlling the initial seed moisture content to ensure the proper quality of the final product was noted.
