“…The variation in the contact angle as a function of time (Figure 3) indicated that the increase in the number of printed layers promoted a reduction in the contact angle in relation to the control OF (without GPEE printing). The contact angle values of chitosanbased films were greater than 90 • C, indicating a hydrophobic character [79,80]. However, the incorporation of GPEE caused a reduction in the contact angle, indicating greater surface hydrophilicity.…”

Oral film (OF) research has intensified due to the effortless administration and advantages related to absorption in systemic circulation. Chitosan is one of the polymers widely used in the production of OFs; however, studies evaluating the maintenance of the active principles’ activity are incipient. Propolis has been widely used as an active compound due to its different actions. Printing techniques to incorporate propolis in OFs prove to be efficient. The objective of the present study is to develop and characterize oral films based on chitosan and propolis using printing techniques and to evaluate the main activities of the extract incorporated into the polymeric matrix. The OFs were characterized in relation to the structure using scanning and atomic force electron microscopy; the mechanical properties, disintegration time, wettability, and stability of antioxidant activity were evaluated. The ethanolic extract of green propolis (GPEE) concentration influenced the properties of the OFs. The stability (phenolic compounds and antioxidant activity) was reduced in the first 20 days, and after this period, it remained constant.

Melanosis is a bio‐chemical reaction that reduces the acceptability of refrigerated shrimps. The current research aims to produce and characterize chitosan‐based coatings added of propolis extract (PE), as well as to investigate the potential application of these materials to control the melanosis of refrigerated shrimps during storage (9 days). Shrimps are coated with chitosan solutions content different PE concentrations (0%, 5%, 10%, and 20%). Uncoated shrimps and shrimps coated with sodium metabisulfite are also investigated. The incorporation of PE modifies the crystalline structure of chitosan, reducing the water contact angle, and thermal stability of films. Shrimps coated with chitosan‐based solutions containing 20% of PE display lower dark points in the cephalothorax and joints region, as well as better weight retention during storage. These results suggest that chitosan‐based coatings containing PE can be an eco‐friendly alternative to substitute sodium metabisulfite in refrigerated shrimps.
