17. Physicochemical characteristics and sensory acceptance of jambolan nectars ( Syzygium cumini)
Abstract The market for ready-to-drink fruit nectars is one of the fastest growing ones, because fruits provide beneficial effects for health maintenance and disease prevention, mainly due to the presence of phenolic compounds and their antioxidant activity. Amongst these, jambolan stands out, but is still little explored. The objective of the present work

19. Comparative evaluation between mechanical and pneumatic cells for quartz flotation in the iron ore industry
Abstract Flotation plays a relevant role in the concentration of iron ores. Conventional flotation technology employing mechanical machines and columns and also circuits combining both types of cells have been utilized in the iron ore industry. The top size of particles in the flotation circuit feed is 150 µm and the slimes below 10 µm are removed as overf

24. THE FUNGAL ABILITY FOR BIOBLEACHING/BIOPULPING/BIOREMEDIATION OF LIGNIN-LIKE COMPOUNDS OF AGRO-INDUSTRIAL RAW MATERIAL
Lignin is present in plant cell secondary wall, associated to carbohydrates preventing their efficient hydrolysis, and cellulose pulp manufacture basically consists in breaking down the middle lamella of plant cells, individualizing fibers such as cellulose from the other biopolymers. Different levels of lignocellulose are found in plant residues and they ca
