Homogenate of drone larvas is not synthetic, but the natural product, so it should be
included in the diet as a nutritional protein food that is not inferior to animal meat, and even
exceeds its content of microelements and vitamins. As a separate biologically active food
homogenate of drone larvas are relatively new, which interests scientists and nutritionists
with its properties. Analyzing the work of scientific institutions and individual scientists on
the qualitative and quantitative composition of a homogenate of drone larvas, we noted
inconsistencies in the results obtained by them. For example, Lazarian in his work (2002)
indicates that homogenate of drone larvas has 38.5 % of protein content and Grechka (2005)
notes this index in the amount of 13.0 %. Burmistrova (2009) indicates that its active acidity
(pH) level of a homogenate of drone larvas ranges from 4.8 to 6.7, whereas Prohoda (2007)
notes that this neutral (pH-7). The same trend is observed with the content of hormones.
Thus, Osyntseva (2012) found that the amount of testosterone and estradiol in the body of 5-6
day old larvas is 8.19 and 274.50 nmol/liter, respectively, and in studies of Bogdanov (2016),
these figures are indicated in quantity of 0.31 and 677.6 nmol/100 grams, respectively.
Therefore, the purpose of our work was to investigate the homogenate of drone larvae
of different ages by biochemical composition.
The study of these tasks was initiated at the industrial apiary of BEEHIVE Company in
May 2019. The material for conducting research homogenates of drone larvae aged from 5 to
8 days.
The protein content of the drone larvae homogenate was found to be 14 % dependent
on age, its active acidity (pH) level ranges from 5.68 to 6.44, and the flavonoid compounds
ranged from 0.73 to 1.8 %. The mass fraction of crude fat in the homogenate of drone larvae of
8-day age is 2.28 %.
So, now it is scientifically proven that homogenate of drone larvas contains a large
number of biologically active substances, but the dynamics of the transformation of
quantitative and qualitative composition, considering physiological stages of drone larvas in
colonies of different breeds (races) in various climatic conditions of Ukraine, is still not
sufficiently studied. The very technology of homogenate of drone larvas production needs to
be improved in view of these figures.

Keywords: bee colonies, chemical composition, homogenate of drone larvas.
