Valorization of Xylan in Agroforestry Waste Streams.
Harrison Appiah
Microwave-assisted deep eutectic solvent and gamma-valerolactone metallic chloride catalyzed conversion of xylan to furfural were investigated using a 2x3 factorial experimental design at two levels of percent microwave power, reaction time, and catalyst concentration. The levels of each factor studied were (20%, 60% microwave power, 2, 4 minutes, and 10, 20mg) respectively. The effect of three metallic chloride catalysts (LiCl, FeCl3.6H20, CuCl2) on the conversion of xylan to furfural was also investigated. The gamma-valerolactone-ferric chloride sent system exhibited the highest mean yield of furfural (56.50%). The next highest furfural yield of …

Graduate Theses, Dissertations, and Problem Reports
Refined Liquid Smoke (RLS) (1%) was incorporated during osmotic dehydration of apple cubes (10 mm each side) to observe its effect on solid gain, water loss, yield, water activity, product quality, and consumer preference. Three different treatments, POD (pure osmotic dehydration, no RLS), LSISS (RLS inside sugar solution) and PTLS (pre-treatment with RLS), were compared in this study. Osmotic dehydration was carried out using 42 °Brix sugar solution, and the fruit to solution ratio was kept at 1:4. The osmotically dehydrated apples were evaluated for soluble solid content (SSC), water loss, and solid gained. After osmotic dehydration, apple cubes were …

Background: In recent studies, mixed forests were found to be more productive than monocultures with everything else remaining the same.
Methods: To find out if this productivity is caused by tree species richness, by a more heterogeneous stand structure or both, we analyzed the effects of forest structure and tree species richness on stand productivity, based on inventory data of temperate forests in the United States of America and Germany.
Results: Having accounted for effects such as tree size and stand density, we found that: (I) tree species richness increased stand productivity in both countries while the effect of tree …
