Understanding the effects of chitosan, chia mucilage, levan based composite coatings on the shelf life of sweet cherry.

Sweet cherry (Prunus avium L.) fruits are prone to quality and quantity loss in shelf-life conditions and cold storage due to their short post-harvest life. Until now efforts have been made to extend the shelf life of the sweet cherry.

Understanding the effects of copolymerized cellulose nanofibers and diatomite nanocomposite on blend chitosan films.

Chitosan films lack various important physicochemical properties and need to be supplemented with reinforcing agents to bridge the gap. Herein, we have produced chitosan composite films supplemented with copolymerized (with polyacrylonitrile monomers) cellulose nanofibers and diatomite nanocomposite at different concentrations. The incorporation of CNFs and diatomite enhanced the physicochemical properties of the films.

Natural β-chitin-protein complex film obtained from waste razor shells for transdermal capsaicin carrier.

In the literature, the produced β-chitin samples are in powder or flake forms but there is no natural β-chitin based film. Also, the commercially available transdermal patches are produced from synthetic polymers. In this regard, we produced natural β-chitin-protein complex (CPC) film from the waste shells of Ensis spp.

Use of sea urchin spines with chitosan gel for biodegradable film production.

In recent years, the film production from natural polymers has considerably increased in food industry as an alternative to the petroleum based synthetic films. Chitosan is one of the most preferred biopolymers for bio-based film production, due to its biocompatibility, biodegradability, antioxidant activity and antimicrobial properties. Because of its hydrophilic properties, chitosan based films dissolve in water, limiting its uses in industry, to overcome this problem; we mixed 200 and 400 mg of the sea urchin spine powder (SUSP) with 20 mL chitosan gel respectively, to obtain a hydrophobic film.

Effect of different animal fat and plant oil additives on physicochemical, mechanical, antimicrobial and antioxidant properties of chitosan films.

Practical application of chitosan-essential oil blend films is limited due to the uneconomical extraction procedure of essential oils from plants. This study aimed to produce chitosan films blended with low cost and commercially available oils and fats consumed in daily human diet (olive, corn and sunflower oils, butter and animal fats). The study also focused on how physicochemical, biological and mechanical properties of chitosan blend films were influenced by the incorporation of oils and fats with varying unsaturation degrees.
