Crotalaria juncea bast fibers a novel cellulose rich material is valorized by producing nanocrystals (CNCs) which gained much attention due to its unique properties. CNCs obtained during this study consisted of two steps: pretreatment C. obtain chemically purified followed sulfuric acid hydrolysis. Efficacy different methods chlor-alkali method (pre-treatment-I) and ultra sound assisted chlorin...

this study examined if pre-germination altered the water content and water activity, contents of phytate, total phenolic, (±)-catechin, quercetin and total antioxidant capacity of almond  (prunus dulcis)kernel. raw almond kernels were submerged for 15 hours in water, 0.02 mol dm-3 phosphate buffer solution (ph 5.0) and 0.02 mol dm-3 phosphate buffer solution (ph 7.0) at 25 and 40ºc, respectivel...

the aim of this research was to use osmosis-ultrasound compound pre-treatment and studying the time of drying and the potentiality to rehydration in dried samples of kiwi fruit (hayvard variety). the samples were drained in three timed phases, 10, 20 and 30 minutes in room temperature in 30, 50 and 70 bx in ultrasound bath osmosis solutions. the results of drying time showed that by decreasing ...

This paper presents a review of methods that improve the production of volatile fatty acids (VFA) from excess sludge during the anaerobic digestion process. These methods are mainly divided into two approaches. The first approach is located in the pre-treatment methods, which change the properties of the substrates, such as thermal pre-treatment, alkaline pre-treatment, microwave pre-treatment ...
