A review of the potential health benefits of pine nut oil and its characteristic fatty acid pinolenic acid
Publication date: May 2016 Source:Journal of Functional Foods, Volume 23 Author(s): Kayin Xie, Elizabeth A. Miles, Philip C. Calder Pine nuts contain pinolenic acid (PNLA), which represents 14–19% of fatty acids present. Here we review research on pine nut oil (PNO) and PNLA from studies performed in vitro, in animal models and in humans. PNLA has anti-inflammatory action and may improve lymphocyte function. PNO and PNLA have favourable effects on appetite control, perhaps by increasing the blood concentrations of key satiety hormones. Less weight gain and fat deposition were observed in mice fed with high fat ...

Identification and characterization of DC‐SIGN‐binding glycoproteins in allergenic foods
ConclusionsWe demonstrate that peanut agglutinin, a minor peanut allergen is a novel ligand for DC‐SIGN. Peanut agglutinin activates DCs to induce expression of co‐stimulatory molecules in vitro. We present a comprehensive report on characterization of DC‐SIGN‐binding proteins in common allergenic foods like peanut, soy, tree nuts, egg and milk. Foods that rarely induce allergy such as pine nuts, chickpea and corn showed no binding to DC‐SIGN. Several DC‐SIGN‐binding proteins show reactivity in serum IgE‐immunoblots. We have also identified novel non‐IgE‐binding proteins that interact with DC‐SIGN; th...

Mutagenicity assessment of aerosols in emissions from domestic combustion processes.
This study aimed at assessing the mutagenicity potential of the fraction of this polycyclic aromatic compound in particles (PM10) from domestic combustion by using the Ames assays with Salmonella typhimurium TA98 and TA100. Seven biofuels, including four types of pellets and three agro-fuels (olive pit, almond shell and shell of pine nuts), were tested in an automatic pellet stove, and two types of wood (Pinus pinaster, maritime pine, and Eucalyptus globulus, eucalypt) were burned in a traditional wood stove. For this latter appliance, two combustion phases-devolatilisation and flaming/smouldering-were characterised separa...

The effect of traditional stir-frying process on hydrophilic and lipophilic antioxidant capacities of pine nut kernels.
Authors: Mao S, Zhou F, Huang W, Lu B, Yang J, He L, Zhao Y Abstract The effect of traditional stir-frying process at different heating temperatures (50-150 °C) and time periods (5-20 min) on hydrophilic part (total and individual phenolics), lipophilic part (tocopherol and phytosterol compounds) and their corresponding antioxidant capacities in pine nut kernels were investigated. The concentrations of total phenolics, phenolic acids, tocopherols and phytosterols in raw pine nut kernels were 15.76 mg gallic acid equivalents/100 g dry weight (mg GAE/100 g DW), 12.15 mg/100 g DW, 28.67 mg/10...

Inhibition in Clark's nutcrackers (Nucifraga columbiana): results of a detour-reaching test.
Abstract Inhibition (i.e. the ability to restrain ineffective responses to a given stimulus) is a good indicator of complex cognitive abilities in animals. Inhibition has been demonstrated in a broad range of mammals with foraging style and social group size identified as potential influences of this ability. Whether these ecological factors also apply to birds has not been well studied. Corvids, a family of birds well known for being able to accomplish difficult cognitive tasks often requiring inhibition, are a good model for studying inhibitory control. During this study, we measured the ability of Clark...

Polymerase chain reaction and chemometrics detected several Pinus species including Pinus armandii involved in pine nut syndrome
In this study, a PCR primer design targeted conserved DNA sequences that span an area of variation between P. armandii and other relevant species. Principal component analysis (PCA) of high-resolution melting curves from PCR amplicons was used to cluster pine species from reference material, and to determine the species of unknown samples. The PCA successfully clustered 2 subspecies/varieties of P. armandii, Pinus bungeana, Pinus massoniana, Pinus pinea, and Pinus wallichiana. Pinus koraiensis/Pinus pumila and Pinus sibirica/Pinus cembra had identical PCR amplicons, respectively, and formed 2 distinct clusters. 12 pine n...

Discovery of highly conserved unique peanut and tree nut peptides by LC–MS/MS for multi-allergen detection
Publication date: 1 March 2016 Source:Food Chemistry, Volume 194 Author(s): Jennifer Sealey-Voyksner, Jerry Zweigenbaum, Robert Voyksner Proteins unique to peanuts and various tree nuts have been extracted, subjected to trypsin digestion and analysis by liquid chromatography/quadrupole time-of-flight mass spectrometry, in order to find highly conserved peptides that can be used as markers to detect peanuts and tree nuts in food. The marker peptide sequences chosen were those found to be present in both native (unroasted) and thermally processed (roasted) forms of peanuts and tree nuts. Each peptide was selected b...

Particulate phase emission of parent polycyclic aromatic hydrocarbons (PAHs) and their derivatives (alkyl-PAHs, oxygenated-PAHs, azaarenes and nitrated PAHs) from manually and automatically fired combustion appliances
In this study, a manually operated batch stove (burning wood logs) and an automatic pellet stove were selected to carry out combustion experiments. Two types of firewood (pine and eucalypt) were used as fuels in the manual stove. Four types of pellets and three agricultural fuels (olive pit, almond shell and shell of pine nuts) were selected for the automatic stove. The particulate matter (PM10) samples from the exhaust flue gas were solvent extracted and analysed for 26 parent and alkyl-PAHs, 15 nitrated PAHs (NPAHs), 15 oxygenated PAHs (OPAHs) and 4 azaarenes (AZAs) by gas chromatography–mass spectrometry. The global p...

Abstract Nuts have received increased attention from the public in recent years as important sources of some essential elements, and information on the levels of elements in edible nuts is useful to consumers. Determination of the elemental distributions in nuts is not only necessary in evaluating the total dietary intake of the essential elements, but also useful in detecting heavy metal contamination in food. The aim of this study was to determine the mineral contents in edible nuts, and to assess the food safety of nuts in the Beijing market.

Activity of dietary fatty acids on FFA1 and FFA4 and characterisation of pinolenic acid as a dual FFA1/FFA4 agonist with potential effect against metabolic diseases.
In conclusion, the present results indicate that pinolenic acid is a comparatively potent and efficacious dual FFA1/FFA4 agonist that exerts antidiabetic effects in an acute mouse model. The compound thus deserves attention as a potential active dietary ingredient to prevent or counteract metabolic diseases.
