Special Issue Information

Dear Colleagues,

Wood and wood bark are important sources of phytochemicals. As demand for renewable natural resources has increased, research on the use of bark phytochemicals has increased as well. Polyphenols extracted from wood or wood bark have bioactive properties that could be utilized in the food and pharmaceutical industry. Extracted and purified compounds could also be exploited as platform chemicals for the chemical industry, since some natural compounds are difficult to synthesize. Technical formulas with crude extracts or compounds purified from extracts can be used in different applications. Mixtures of extracted phytochemicals could, in some cases, have a synergistic effect against certain pathogens or pests. Extraction following characterization and bioactivity of extracts are important steps to verify that compounds are safe and can be used. Robust and verified analytical methods are an important part of the research toolbox. Therefore, new approaches in analytical methods can identify potentially harmful compounds and allow the creation of products that increase the wellbeing and health of consumers.

Following an international trend in using industrial byproducts and taking into account the need to find sustainable uses of different fruit side streams, this Special Issue is dedicated to providing new scientific and technological applications for bioactive compounds from forest materials. Additionally, other chemical compounds with applications in the food, feed, cosmetic, and chemical industries will be considered. These studies may include analytical methods used to assess the chemical composition of forest side streams, bioactivity as assessed by in vitro and in vivo protocols, evaluation of extracting technologies, and comparison between matrices. The use of these bioactive-rich extracts in different applications (pharmaceutical products, food models, etc.) will be a matter of interest.

The Special Issue will cover original research and review articles, according to the Author Guidelines.

The Hydrophobicity of Lignocellulosic Fiber Network Can Be Enhanced with Suberin Fatty Acids

Suberin fatty acids were extracted from outer bark of Silver birch (Betula pendula Roth.) using an isopropanolic sodium hydroxide solution. Laboratory sheets composed of lignocellulosic fiber networks were prepared from unbleached and unrefined softwood kraft pulp and further impregnated with suberin fatty acid monomers and cured with maleic anhydride in ethanol solution. The treatment resulted in hydrophobic surfaces, in which the contact angles remained over 120 degrees during the entire measurement. The fiber network also retained its water vapor permeability and enhanced fiber–fiber bonding resulted in improved tensile strength of the sheets. Scanning electron microscopy (SEM) images revealed that the curing agent, together with suberin fatty acids, was evenly distributed on the fiber surfaces and smoothing occurred over the wrinkled microfibrillar structure. High concentrations of the curing agent resulted in globular structures containing betulinol derivates as revealed with time-of-flight secondary ion mass spectrometry (ToF-SIMS). Also, the larger amount of suberin fatty acid monomers slightly impaired the optical properties of sheets. Full article
