Surface Free Energy Utilization to Evaluate Wettability of Hydrocolloid Suspension on Different Vegetable Epicarps

et al. 2017

Surface free energy is an essential physicochemical property of a solid and it greatly influences the interactions between vegetable epicarps and coating suspensions. Wettability is the property of a solid surface to reduce the surface tension of a liquid in contact with it such that it spreads over the surface and wets it, resulting from intermolecular interactions when the two are brought together. The degree of wetting (wettability) is determined by an energy balance between adhesive and cohesive work. The spreading coefficient (S cf/food ) is the difference between the work of adhesion and the work of cohesion. Surface wettability is measured by the contact angle, which is formed when a droplet of a liquid is placed on a surface. The objective of this work was to determine the effect of hydroxypropyl methylcellulose (HPMC), κ-carrageenan, glycerol, and cellulose nanofiber (CNF) concentrations on the wettability of edible coatings on banana and eggplant epicarps. Coating suspension wettability on both epicarps were evaluated by contact angle measurements. For the (S cf/food ) values obtained, it can be concluded that the surfaces were partially wet by the suspensions. S cf/food on banana surface was influenced mainly by κ-carrageenan concentration, HPMC-glycerol, κ-carrageenan-CNF, and glycerol-CNF interactions. Thus, increasing κ-carrageenan concentrations within the working range led to a 17.7% decrease in S cf/banana values. Furthermore, a HPMC concentration of 3 g/100 g produced a 10.4% increase of the S cf/banana values. Finally, S cf/fruit values for banana epicarps were higher (~10%) than those obtained for eggplant epicarp, indicating that suspensions wetted more the banana than the eggplant surface.

“…Furthermore, the waste derived from pineapple (Ananas cosmosus) contains 25.8% reducing sugars and 11.2% cellulose (Rani and Nand 2004). Castro et al (2011) also reported that pineapple peel juice contains 2.14% w/v glucose, 2.4% w/v fructose, and 2.10% w/v sucrose. Simultaneous saccharification and fermentation (SSF) or simultaneous saccharification and co-fermentation (SSCF) methods both perform well in the bioconversion of lignocellulosic materials to bioethanol.…”

Bioethanol is a renewable energy source, and its production from agricultural wastes, such as banana and pineapple peels, is an economical approach. Enzymatic hydrolysis experiments were performed using a simultaneous saccharification and co-fermentation (SSCF) method. Banana and pineapple wastes inoculated with Aspergillus terreus and Kluyveromyces marxianus produced the maximum ethanol concentrations of 0.35 g/L and 0.27 g/L, respectively. Furthermore, logistic unstructured and incorporated models described well the growth of microorganism, product formation, and substrate utilization during SSCF system with high R 2 and low RMSD.

“…Each is produced extensively by natural processes and can be extracted from bacteria, plants, and animals. [18][19][20] Biopolymers are uniquely similar to biological macromolecules and can be utilized to stimulate specifi c cellular responses that synthetic polymers cannot. Moreover, biopolymers possess highly organized structures that contribute to cellular growth at various stages of development.…”

With nearly 30 years of progress, tissue engineering has shown promise in developing solutions for tissue repair and regeneration. Scaffolds, together with cells and growth factors, are key components of this development. Recently, an increasing number of studies have reported on the design and fabrication of scaffolding materials. In particular, inspired by the nature of bone, polymer/ceramic composite scaffolds have been studied extensively. The purpose of this paper is to review the recent progress of the naturally derived biopolymers and the methods applied to generate biomimetic biopolymer/calcium phosphate composites as well as their biomedical applications in bone tissue engineering.
