Inductively coupled plasma-mass spectrometry (ICP-MS) and -optical emission spectroscopy (ICP–OES) for determination of essential minerals in closed acid digestates of peanuts (Arachis hypogaea L.).

Validated methods to measure the essential mineral composition of food matrices are needed to satisfy the analytical requirements of product development, quality control, and food regulatory authorities. We investigated the use of inductively coupled plasma–optical emission spectroscopy (ICP–OES) and -mass spectrometry (ICP-MS), with and without the use of a dynamic reaction cell (DRC), to analyse […]

Hexavalent chromium removal from aqueous medium by activated carbon prepared from peanut shell: Adsorption kinetics; equilibrium and thermodynamic studies

Activated carbon was prepared from peanut shell by chemical activation with KOH. Unoxidized activated carbon was prepared in nitrogen atmosphere which was then heated in air at a desired temperature to get oxidized activated carbon. The prepared carbons were characterized for surface area and pore volume and utilized for the removal of Cr(VI) from aqueous […]

Preparation of peanut hull-based activated carbon by microwave-induced phosphoric acid activation and its application in Remazol Brilliant Blue R adsorption

Peanut hull; an agricultural solid waste abundantly available in China; was utilized as a precursor for preparation of activated carbon via microwave induced phosphoric acid chemical activation. To optimize the preparation conditions; the effects of the concentration of phosphoric acid; microwave power and radiation time on the adsorption property (expressed in terms of the iodine […]

Resveratrol; a neuroprotective supplement for Alzheimer's disease

The polyphenolic compound resveratrol (3;4';5-trihydroxystilbene) is a naturally occurring phytochemical which has been found in more than 70 plant species; including herbs and human food products such as grapes; berries; and peanuts. Resveratrol was first isolated in 1940; however; little attention was paid to it until its benefits in coronary heart disease were studied in […]

The study of ultrasonic-assisted aqueous enzymatic extraction of oil from peanut by response surface method

Based on the optimum ultrasonic temperature and time parameters obtained from single-factor experiment; the response surface analysis method is employed to design and optimize the parameters in the experiment. The optimum parameters obtained from response surface analysis are as follows: enzyme additive amount 1.7%; hydrolysis time 3.8 h; hydrolysis temperature 56 °C; materials to water […]

Antioxidant capacity and sensory profiles of peanut skin infusions

The popularity of functional beverages such as tea and herbal infusions led to the search for alternative sources of raw materials that provide great taste and functionality to consumers. Peanut skins are a rich source of phenolic compounds and their utilization in beverage was attempted. Total phenolics (TP) and antioxidant capacity (AOC) were determined in […]

Selection of intermittent drought tolerant lines across years and locations in the reference collection of groundnut (Arachis hypogaea L.)

Intermittent drought is the most important yield limiting factor affecting groundnut (Arachis hypogaea L.) production in rain-fed regions of Sub-Saharan Africa and Asia. Improvement of crop adaptation to drought is needed and this starts by having a thorough assessment of a large and representative set of germplasm. In this study; 247 lines belonging to the […]

Profiling of bioactive compounds in cultivars of Runner and Valencia peanut market-types using liquid chromatography/APCI mass spectrometry

Peanuts are classified into four market-types (Runners; Spanish; Virginia and Valencia) Studies on their phytochemical composition have focused mainly on market-types other than Valencia. The objectives of this study are to evaluate the phytochemical composition of cultivars of Valencia and Runner market-types. Extracts of twenty-five peanut cultivars of Runner and Valencia market-types were analyzed using […]

The eliciting dose of peanut in double-blind; placebo-controlled food challenges decreases with increasing age and specific IgE level in children and young adults.

Background: Several risk factors for severe anaphylactic reactions to food in daily life are known. However; to date; it is not possible to predict the severity of allergic reactions to food in the individual patient with accuracy. Some studies show that a history of severe reactions is associated with a lower eliciting dose in double-blind; […]

Resveratrol induces mitochondria-mediated AIF and to a lesser extent caspase-9-dependent apoptosis in human lung adenocarcinoma ASTC-a-1 cells

Resveratrol (RV); a natural plant polyphenol widely present in foods such as grapes; wine; and peanuts; has an ability to inhibit various stages of carcinogenesis in vitro and in vivo. In this report; we explored the roles of intrinsic and extrinsic apoptotic pathways during RV-induced apoptosis in human lung adenocarcinoma (ASTC-a-1) cells. After exposure of […]
