Bovine serum albumin is the key protein in blood. Chitin is a widely used biocompatible polymer inbioengineering and it is mainly found as two allomorphs (a, b). In this study the interactions of a-chitin(from the insect Omophlus sp.) and b-chitin (from the cuttlebone of Sepia sp.) with BSA were studied. Chitin isolates were examined by SEM, XRD, BET, TGA and FTIR. b-Chitin exhibited a far higher affinity forBSA than a-chitin, indicating a-chitin can be used in applications where surface–protein interactionsshould be limited, and b-chitin can be used in chitin-based materials on which protein adsorption isdesired.

Sporopollenin-chitosan blendfilms were produced for thefirst time. Sporopollenin is a robust structuralcomponent of plant pollens exhibiting excellent features such as nontoxicity, biodegradability,biocompatibility, high thermal stability, durability to strong acid and base solutions and homogeneityin size. To benefit from these advantages, sporopollenin samples obtained from Betula pendula (silverbirch) were incorporated into chitosanfilm at different concentration; 10, 20 and 40 mg in 100 mLchitosan gel (1%). Stereo microscopy, FT-IR and TG/DTG analyses showed that sporopollenin wassuccessfully incorporated into the chitosan matrix. Incorporation of sporopollenin in gradually increasingamount into chitosanfilms was found advantageous in (1) enhancement in chemical durability of thefilms, (2) increment of hydrophobicity, (3) boosting the mechanical properties, (4) improvement ofantifungal and (5) antioxidant activities. This study revealed that sporopollenin can be suggested as aneffective blend material for biodegradable edible chitosanfilm production.
