Physico-chemical parameters of drone brood homogenate adsorbed on lactose-free adsorbents during storage

Abstract. Drone brood is a product that exhibits high biological activity, so its use can be recommended to a wide range of people as an adaptogenic, actoprotective and antioxidant agent. The high concentration of biologically active substances, such as decenoic acids, unsaturated fatty acids, sulfhydryl groups, sugars, hormones and hormone-like compounds makes drone brood a product very sensitive to environmental factors, which necessitates its stabilization. To stabilize drone brood homogenate, in a number of countries, a lactose-glucose adsorbent is usually used. The relevance of the work is due to the widespread prevalence of lactase deficiency among the population, the prevalence of which among the Eastern Slavs reaches 16–18 %, and among some peoples of Asia, Australia and America exceeds 80 %, which limits the use of adsorbed drone brood using a classical adsorbent containing lactose. The purpose of the work is to develop an innovative product based on drone brood that does not contain lactose as an adsorbent, and to trace the dynamics of the preservation of its biologically active components during storage. Potato starch was used as a lactose substitute in the adsorbent. This product can be recommended to a wider range of consumers. The work used methods for determining the physicochemical parameters of products, such as humidity, oxidation index, hydrogen index, mass fraction of decenoic acids, mass fraction of crude protein, free acidity, acid number, iodine number. The scientific novelty lies in the development of formulations for new products based on drone brood that do not contain lactose and the determination of the optimal product among them in terms of technological and physicochemical parameters. As a result of the studies, it was found that an adsorbent consisting of 80 parts of starch and 20 parts of glucose provides optimal product performance at a ratio of adsorbent to drone brood homogenate of 3 : 1.
