Reducing agents of drone brood products supplemented by royal jelly, propolis and chitosan derivatives

Abstract

Violation of the ratio of nutrients causes diseases. Antioxidants occupy a special place among micronutrients, which can slow down aging and prevent the development of tumors. Bee products, especially drone brood, propolis, royal jelly, and chitin-chitosan-melanin complex, are rich in antioxidants. This requires the development of new combined products that have a complex effect on the human body. As an indicator of the content of unsaturated compounds, the iodine number of the drone brood adsorbed by lactose-glucose adsorbents, as well as supplemented by the chitin-chitosan-melanin complex, propolis extract and royal jelly, was studied. The results showed that new products have a higher iodine number compared to drone brood on lactose-glucose adsorbents. This is promising for the widespread use of new products in human nutrition. The iodine number can be a reliable indicator of quality.

Searching for Differences in Chemical Composition and Biological Activity of Crude Drone Brood and Royal Jelly Useful for Their Authentication

“…Thus, the highest values obtained by DPPH and FRAP methods for 11-day-old DB in this study are in line with our earlier report [ 22 ]. Drone brood antioxidants are represented by polyphenolic compounds, vitamins C and E, enzymes, unsaturated fatty acids in free and bound forms, including unique decenoic acids, substances having sulfhydryl groups, flavonoid, and other phenolic compounds [ 42 ]. Silici [ 13 ] examined the bioactivity of apilarnil (lyophilized drone brood) and showed the total phenolic content at the level 834.05 mg GAE/100 g which is comparable with the results of this work when calculated them to dry mass.…”

Antioxidant Activity of Frozen and Freeze-Dried Drone Brood Homogenate Regarding the Stage of Larval Development

“…However, the composition of drone milk has been poorly studied with respect to the protein, amino acids, lipids, hormones, vitamins, and bioelements that make it a good source of antioxidants [10,11,21]. Flavonoids and other phenolic compounds are important components that contribute to the ability of drone brood to reduce oxidative stress and prevent cardiovascular diseases [22], but still have not been recognized.…”
