Characterization of Polyphenolic Compounds Extracted from Different Varieties of Almond Hulls (Prunus dulcis L.).

Ultrasound-assisted extraction (UAE) was applied as a pretreatment technique to improve the recovery of polyphenols from the almond hulls of four Tunisian and three Italian almond varieties, followed by the characterization with HPLC-DAD. The operating parameters (solid/liquid ratio, extraction time, and ethanol concentrations) were optimized using a Response Surface Methodology. A polynomial equation was calculated […]

FT-IR spectroscopy and Morphological study of functionalized cellulosic fibers: Evaluation of their dyeing properties using biological Pistacia vera hulls by-product extract.

The repulsion between cellulose and anionic entities could be overcome by imparting cationic sites on its structure. In this work, we studied the treatment of cotton fabric with different amounts of chitosan bio-polymer (0.0125-0.075%), dimethyl diallyl ammonium chloride and diallylamin co-polymer (1-5%), alum (0.5-20 g/L), and sodium chloride (2-40 g/L) in order to improve their […]

Co-processing of common plastics with pistachio hulls via hydrothermal liquefaction.

Mixed, wet, plastic streams containing food waste residues are being increasingly collected at point of use, but are extremely challenging to recycle and are therefore largely sent to landfill. While a challenging waste problem, this also represents an underutilised feedstock, which could be co-processed with biomass, increasing the scope of products, easing out seasonal variation […]

Porous β-Mo2C Nanoparticle Clusters Supported on Walnut Shell Powders Derived Carbon Matrix for Hydrogen Evolution Reaction.

Herein, we choose the waste walnut shell as the carbon source, and ammonium heptamolybdate as the molybdenum source to prepare the β-Mo2C catalyst supported on carbon matrix (Mo2C@C) by the calcination method for hydrogen evolution reaction (HER). The open pores in the porous Mo2C nanoparticle clusters can facilitate electrolyte permeation and hydrogen molecules release as […]

Data on environmental analysis of natural antioxidant production from walnut husk by a solar photovoltaic-driven system as a replacement for potentially carcinogenic synthetic antioxidants.

In order to develop a product sustainably, multiple analyses, including comprehensive environmental assessment, are required. Solar-assisted production of walnut husk methanolic extract (WHME) as a natural antioxidant for biodiesel was scrutinized by using the life cycle assessment (LCA) approach. More specifically, the environmental sustainability of WHME antioxidant was evaluated and compared to that of propyl […]

Chemical and Pharmacological Evaluation of Hulls of Prunus dulcis Nuts.

Researchers have shown that the almond hulls, normally wasted after utilization of nuts, contain a number of biologically active compounds based on which the present study has been carried out. Focus is placed on the mass spectrometric determination of the analytes along with the estimation of total polyphenolic and total flavonoid contents in the 70% […]

Development of functional edible oils enriched with pistachio and walnut phenolic extracts.

The purpose of this research was the development of functional edible oils with potential health promoting effects, enriched with phenolic-rich extracts obtained from pistachio and walnut. A high phenolic content, 10860 mg/kg and 7030 mg/kg in walnut and pistachio kernels respectively, with a corresponding strong radical scavenging effect (DPPH, 106 and 20 mmol/kg Trolox) were […]
