“…The peaks around 3400 cm −1 at FTIR results are related to the stretching vibration of the –NH 2 (chitosan samples) or –OH groups (alginate and xanthan samples) [ 21 , 22 , 23 ]. The high intensity of vibration in this region for G, C1G2, and C1A2 samples indicates that the hydrogen bonding is enhanced, since this peak is also related to the intramolecular hydrogen bonds present in the structure of all three polymers and polyelectrolytes.…”

“…At pH 7.0 (after the neutralization step of the “onion-like” process), the proportion of protonated and unprotonated amino groups from chitosan could have produced changes in the intensity of this peak. The hypsochromic shift of the C=O peak pointed to the interaction between NH 3 + groups of chitosan and negative groups of xanthan or alginate [ 21 ]. In a similar study, Takara et al showed that treatment of NaOH decreased the intensity of amino group peaks (around 1650 cm −1 ) in chitosan films due to deprotonation [ 24 ].…”

Superabsorbent hydrogels (SAHs) are three dimensional networks formed by polymers that can absorb aqueous solution of over 100% of their initial weight. This work aimed to develop and characterize SAHs of Chitosan/Xanthan gum (CG), Chitosan/Alginate (CA) and controlled Chitosan (C), Xanthan gum (G), and Alginate (A) produced using “onion-like” methodology. The swelling performance, the morphological structure, the crystallinity, and the Fourier transformed infrared spectroscopy characteristics of SAH were used for the characterization of polyelectrolytes complex. Swelling analysis showed that chitosan has a strong influence on the maintenance of hydrogels structure after swelling, mainly in the acid environment (pH = 2). The chitosan hydrogel presented around 3000% of acidic fluid absorption after 24 h. The chitosan:xanthan gum (1:1 and 2:1 named as C1G1 and C2G1, respectively) hydrogels were the best combination regarding swelling performance in an acid environment, reaching 1665% and 2024%, respectively, as well at pH 7.0, presenting 1005% (C1G1) and 667% (C2G1). Scanning electron microscopy analysis showed samples with pores, and with different shapes. The X-ray diffraction showed the presence of a characteristic peak at 2Ɵ = 20° in all developed composition because of the crystalline nature of chitosan. This work shows the possibility of developing eco-friendly biopolymer-based SAHs at a low cost with a good swelling capacity and stability.

In recent years, the use of complex molecules based on the natural biopolymer chitin and/or on its deacetylated derivative chitosan has resulted in great advantages for many users. In particular, industries involved in the production of drugs, cosmetics, biotechnological items, and food have achieved better results using these particular molecules. In plants, chitin- and chitosan-based molecules are largely used as safe and environmental-friendly tools to ameliorate crop productivity and conservation of agronomic commodities. This review summarizes the results of the last two years on the application of chitin- and chitosan-based molecules on plant productivity. The open questions and future perspectives to overcome the present gaps and limitations are also discussed.

Banana is very important for both food and economic securities in many tropical and subtropical countries, because of its nutritional values. However, banana fruit is a climacteric fruit which has short shelf life, so an alternative method to delay its ripening is needed. Our group has used carrageenan as an edible coating to delay banana fruit ripening. In this study, the effect of different concentrations of carrageenan and storage temperatures on Cavendish banana shelf life and fruit quality was evaluated. The fruits were treated with 0.5%, 1.0%, and 1.5% carrageenan and stored at two different temperatures, 26°C and 20°C. Carrageenan functional groups in banana peel samples as well as changes in surface structure of banana peel, color, weight loss, pulp to peel ratio, total soluble solid, and levels of MaACS1 and MaACO1 gene expression were analyzed. Result showed that the optimum condition to extend shelf life and maintain fruit quality was by treating the banana fruits with 1.5% carrageenan and storing them at a cool temperature (20°C). In addition, the result obtained from this study suggested that carrageenan can be used as edible coating to extend the shelf life of banana fruits (Musa acuminata AAA group).
