Abstract: In the present paper, we examined Lucuma powder. Nowadays, the subtropical fruit has been considerate as a functional food product with health benefits, a source of bioactive compounds (BAC), knows as part of “Superfoods”. The current scientific research is focused on the two different experimental types of storage. The Lucuma powder was packed in a co-extruded barrier film with copolymer covering for heat sealing. The first storage was executed for three months at initial humidity of the product – 9.71%, stored at room temperature – 18°С÷25°С and relative air humidity of 45% to 55%. The storage regime was optimized to six months at the same condition (temperature and relative humidity). Flour was dried to humidity – 2.95%, corresponded monolayer moisture content (MMC), and determined using linealization of Brunauer-Emmett-Teller (BET) equation. Those results about MMC for adsorption were in the range of 2.93% to 4.18 % and for desorption – from 2.56% to 4.17%. During the studies of L
