background and objectives: tree nuts and their oils contain bioactive materials which have vital roles in improving human’s health. degradation and decreasing the quality of the nuts especially in almond which have high fat is related to the oxidation. the quality of stored almond depends mainly on the kernel moisture and fat , storage temperature, relative humidity, oxygen level, type of packa...

The agriculture lignocellulosic by-products are receiving increased attention, namely in the search for filter materials that retain contaminants from water. These by-products, specifically almond and hazelnut shells are abundant in Portugal once almond and hazelnuts production is a local important activity. Hazelnut and almond shells have as main constituents lignin, cellulose and hemicellulos...

In this laboratory scale study, impregnated almond shell activated carbon was used as adsorbent to investigate its feasibility for nitrate adsorption from aqueous medium. The effects of activated carbon dosage and contact time have been examined in batch experiments. Experimental data show that impregnated activated carbons by Fe0, Fe2 (SO4)3, and FeSO4 were more effective than virgin almond ac...

This paper investigates a method for the determination of the maximum sampling error and confidence intervals of thermal properties obtained from thermogravimetric analysis (TG analysis) for several lignocellulosic materials (ground olive stone, almond shell, pine pellets and oak pellets), completing previous work of the same authors. A comparison has been made between results of TG analysis an...

abstract almond is an important nut tree which is cultivated in many mediterranean countries. this study was carried out to study some vegetative and reproductive traits as well as qualitative and quantitative characteristics and their correlation in some self-compatible and self-incompatible genotypes obtained from crossing between touno (male parent) and shahrood 12 (female parent). quantitat...

The almond, which is a member of the Rosaceae family, is the fruit of the almond tree (Prunus dulcis). It has a hard endocarp that contains a seed covered by a rough, brownish skin. Unlike other prunoid fruits, which have an edible mesocarp and an outer skin known as the epicarp, the almond fruit has an epicarp and a mesocarp that are diffi cult to separate and have no nutritional or commercial...

The catalytic effect of mineral components (K, Ca, Mg and Na), after pre-treatment by water leaching adding NaCl, was evaluated in fast pyrolysis with the biomass four types agricultural waste (olive pomace, nutshell, almond shell, pistachio shell). Water proved to be effective at reducing content raw materials, especially terms removing K. As a consequence, there lower decarboxylation activity...
