AB  - Finding a pollen substitute for honey bees that is nutritionally adequate and affordable is a scientific and practical challenge. We attempted a new rational approach and tried to exploit honey bees’ natural cannibalistic behavior. We tested processed insect larvae as a food source that is nutritionally similar to bee brood, and which can easily be produced on a large scale. In cage experiments, monitoring bee mortality, food consumption and changes in bee body parts’ weights showed that flour obtained by grinding dried yellow mealworm larvae has the potential to become an excellent component for pollen substitution. Bees from the cage group fed Tenebrio molitor patties (TG) demonstrated overall best results in comparison to sugar patties fed bee group (CG), yeast patties fed bee group (YG) and pollen patties fed bee group (PG). They did not lose weight as rapidly as the CG, did not defecate inside cages as the YG, nor show increased mortality as the PG. At the same time, TG consumed less food (mean 13.7 g/cage) than CG (16.8 g/cage), YG (20.4 g/cage) and PG (23.9 g/cage) within the period of 28 days. Bees’ gut increase in weight was lowest in the CG, followed by TG and PG and was the highest in the YG which resulted in diarrhea after 14 days. Bees from TG did not lag behind other bees in head, thorax and abdomen weight after 28 days. We demonstrated that processed yellow mealworm larvae (T. molitor) can be used as an ingredient for honey bee feed.

AB  - Pectinases are widely used in the fruit juice industry for clarification, liquefaction and stabilization of juices 1. One of the biggest problems in the production of fruit juices is the turbidity of the juice, which is mainly caused by the presence of pectin polysaccharides. Therefore, pectinase is used in juice clarification, which breaks down the pectin structure and reduces unwanted cloudiness and sediment2. In this work, the production of pectinases was optimized by solid state fermentation using Aspergillus tubingensis strain, which proved to be an efficient producer of these enzymes. Statistical method Design of Experiment was used to optimize the medium and conditions for enzyme production. The total pectinase activity obtained was determined by the DNS method (47 U/mL). Endo- pectinases activity is determined by reduction of viscosity of pectin solutions. The resulting complex of pectinase enzymes was used for the liquefaction of apricot and blueberry pulp, with a juice yield of 72% and 81%, respectively. Also, apricot juice treated with enzymes was clarified by 77% compared to juice that was not treated with enzymes. Blueberry juice obtained after treatment with pectinase enzymes has a higher antioxidant activity than the untreated juice, as determined by the DPPH assay.
