Anacardium Plants: Chemical, Nutritional Composition and Biotechnological Applications.
Anacardium plants are native to the American tropical regions, and Anacardium occidentale L. (cashew tree) is the most recognized species of the genus. These species contain rich secondary metabolites in their leaf and shoot powder, fruits and other parts that have shown diverse applications. This review describes the habitat and cultivation of Anacardium species, phytochemical and nutritional composition, and their industrial food […]
The Puzzle of the Walnut Shell: A Novel Cell Type with Interlocked Packing.
The outer protective shells of nuts can have remarkable toughness and strength, which are typically achieved by a layered arrangement of sclerenchyma cells and fibers with a polygonal form. Here, the tissue structure of walnut shells is analyzed in depth, revealing that the shells consist of a single, never reported cell type: the polylobate sclereid cells. These […]
Almond shell as a microporous carbon source for sustainable cathodes in lithium–sulfur batteries.
A microporous carbon derived from biomass (almond shells) and activated with phosphoric acid was analysed as a cathodic matrix in Li–S batteries. By studying the parameters of the carbonization process of this biomass residue, certain conditions were determined to obtain a high surface area of carbon (967 m2 g−1) and high porosity (0.49 cm3 g−1). This carbon […]
Valorisation of Cashew Nut Shell Liquid Phenolics in the Synthesis of UV Absorbers.
With current concerns over the use of fossil resources for chemical synthesis of functional molecules and the effect of current UV absorbers in sunscreens have on the ecosystem, we describe a xylochemical synthesis of different classes of aromatic UV absorbers utilizing cashew nut shell liquid as a non‐edible bio‐renewable carbon source. Hydroxybenzophenones, xanthones, triazines, and […]
Phoenix dactylifera L. seeds: a by-product as source of bioactive compounds with antioxidant and enzyme inhibitory properties.
Date (Phoenix dactylifera L.) seeds are a valuable and abundant by-product with various potential food applications and a source of functional and bioactive ingredients. In this study, date seeds from eight cultivars (Ourous "OUR", Tazizaout "TAZ", Tazarzeit "TAR", Tazoughart "TAG", Ouaouchet "OUC", Oukasaba "OUK", Delat "DEL" and Tamezwertn'telet "TWT") cultivated in the M'zab oasis (south of […]
Enzymolysis of walnut (Juglans regia L.) meal protein: Ultrasonication‐assisted alkaline pretreatment impact on kinetics and thermodynamics.
To improve the utility of walnut meal protein, influences of ultrasonication on the kinetic and thermodynamic constraints of enzyme (trypsin) hydrolysis were assessed using a multi-frequency counter current S-type ultrasound machine. Results revealed that both the ultrasonication treatment and control hydrolysis obeyed the first-order kinetics within the study constraints. After 90 min hydrolysis time, the uppermost […]
Isolation and Characterization of Nanocellulose with a Novel Shape from Walnut (Juglans Regia L.) Shell Agricultural Waste.
Herein, walnut shell (WS) was utilized as the raw material for the production of purified cellulose. The production technique involves multiple treatments, including alkaline treatment and bleaching. Furthermore, two nanocellulose materials were derived from WS by 2,2,6,6-tetramethylpiperidine-1-oxyl radical (TEMPO) oxidation and sulfuric acid hydrolysis, demonstrating the broad applicability and value of walnuts. The micromorphologies, crystalline structures, […]
Effects of hazelnut skin addition on the cooking, antioxidant and sensory properties of chicken burgers.
The aim was to evaluate the effects of hazelnut skin (HS) addition on the oxidation and sensorial properties of chicken burgers during storage and after cooking. Burgers were prepared and divided in five groups: [C] control without HS addition, [CAA] control with ascorbic acid, and [HS1] 1%, [HS2] 2% and [HS3] 3% HS addition. Burgers for each […]
A highly sensitive GC‐MS method for simultaneous determination of Anacardic Acids in Cashew (Anacardium occidentale) Nut Shell oil in presence of other phenolic lipid derivatives.
The commercial value of Cashew nut shell liquid (CNSL) has become a corner stone in agro waste industry as it is the by-product of the cashew industry which has 1/8 inch thickness of soft honey comb structure. CNSL contains phenolic lipids with aliphatic chains such as anacardic acid, cardanol, cardol, and methyl cardol, and their derivatives. The developed GC/MS […]
Plant Specialized Metabolites in Hazelnut (Corylus avellana) Kernel and Byproducts: An Update on Chemistry, Biological Activity, and Analytical Aspects.
Corylus avellana (hazelnut) is one of the most popular tree nuts on a worldwide basis. The main products of C. avellana are kernels, a nutritious food, with a high content of healthy lipids, contained in a hard shell. In recent years, along with the ongoing research carried out on hazelnut kernels, a growing interest has been addressed to the hazelnut byproducts […]
