    (CEP USM, 2024) Grigoraș, Carolina; Ciocârlan, Alexandru; Gonţa, Maria
    Plant products of S. japonica, more precisely: flowers, fruits and seeds collected in May and September, respectively, have been conditioned, and the products obtained serve as a source of raw material. The extracts were obtained from the vegetable raw material by maceration, distillation and hydrodistillation using various solvents, with the subsequent incorporation into the filmogenic mixture of chitosan:pectin, to obtain polymeric films. The obtained films were evaluated according to quality indices, thus the appearance, smell and mechanical properties were analyzed, the thickness of the films was measured and antioxidant properties were determined. The prepared biomaterials are uniform, thin, elastic, flexible, have no smell and have a specific color of the composition, manifest an antioxidant activity, but this varies depending on the composition of the prepared films.
