Hesperidin, nobiletin, and tangeretin are collectively responsible for the anti-neuroinflammatory capacity of tangerine peel (Citri reticulatae pericarpium).
Abstract
Inhibiting microglial activation-mediated neuroinflammation has become a convincing target for the development of functional foods to treat neurodegenerative diseases. Tangerine peel (Citri reticulatae pericarpium) has potent anti-inflammatory capacity; however, its anti-neuroinflammatory capacity and the corresponding active compounds remain unclear. To this end, the composition of a tangerine peel ethanolic extract was analysed by LC-MS, and the anti-neuroinflammatory ability was evaluated using a lipopolysaccharide (LPS)-activated BV2 microglia culture system. Hesperidin is the most predominant...

Food hypersensitivity in patients over 14 years of age suffering from atopic dermatitis
Conclusion: Food hypersensitivity reactions are recorded in 86% of patients suffering from atopic dermatitis. Nuts, tomatoes, and pollen-associated foods play a role in the majority of patients suffering from atopic dermatitis. (Source: Indian Journal of Dermatology)

Calcineurin phosphatase and phospholipase C are required for developmental and pathological functions in the citrus fungal pathogen Alternaria alternata.
Abstract
Excessive Ca(2+) or the compound interfering with phosphoinositide cycling was found to inhibit the growth of the tangerine pathotype of Alternaria alternata, suggesting a crucial role of Ca(2+) homeostasis. The roles of PLC1, a phospholipase C-coding gene and CAL1, a calcineurin phosphatase-coding gene were investigated. Targeted gene disruption has shown that both PLC1 and CAL1 are required for vegetative growth, conidial formation, and pathogenesis to citrus. Fungal strains lacking PLC1 or CAL1 exhibit extremely slow growth and induce small lesions on calamondin leaves. plc1 mutants produce few...

Determination of five pesticides in juice, fruit and vegetable samples by means of liquid chromatography combined with multivariate curve resolution.
Abstract
The aim of this work was to quantify five commonly used pesticides (propoxur, carbaryl, carbendazim, thiabendazole and fuberidazole) in real samples as: tomato, orange juice, grapefruit juice, lemon and tangerine. The method used for the determination of these analytes in the complex matrices was high-performance liquid chromatography with diode array detection. In order to work under isocratic conditions and to complete each run in less than 10min, the analysis was carried out applying multivariate curve resolution coupled to alternating least-squares (MCR-ALS). The flexibility of this applied mu...

Selecting food: the contribution of memory, liking, and action.
Abstract
The goal of the present experiment was twofold: identifying similarities and differences between flavour memory and visual memory mechanisms and investigating whether kinematics could serve as an implicit measure for food selection. To test flavour and visual memory an 'implicit' paradigm to represent real-life situations in a controlled lab setting was implemented. A target, i.e., a piece of cake shaped like either an orange or a tangerine, covered with either orange- or a tangerine-flavoured icing, was provided to participants on Day 1. On Day 2, without prior notice, participants were requested...

Assessment of tissue distribution and concentration of β-cryptoxanthin in response to varying amounts of dietary β-cryptoxanthin in the Mongolian gerbil.
Abstract
There is a general lack of knowledge regarding the absorption and tissue storage of the provitamin A carotenoid β-cryptoxanthin. The present study investigated the whole-body tissue distribution of β-cryptoxanthin in an appropriate small animal model, the Mongolian gerbil (Meriones unguiculatus), for human provitamin A carotenoid metabolism. After 5 d of carotenoid depletion, five gerbils were euthanised for baseline measurements. The remaining gerbils were placed in three weight-matched treatment groups (n 8). All the groups received 20 μg/d of β-cryptoxanthin from tangerine concentrate, wh...

The effects of daily consumption of β-cryptoxanthin-rich tangerines and β-carotene-rich sweet potatoes on vitamin A and carotenoid concentrations in plasma and breast milk of Bangladeshi women with low vitamin A status in a randomized controlled trial.
CONCLUSIONS: VA capsules increased plasma and milk VA concentrations. The greater change in CX concentrations in the tangerine group than in BC concentrations in the OFSP group suggests that CX in tangerines was better absorbed, but both foods failed to increase milk VA concentrations. This trial was registered at clinicaltrials.gov as NCT01420406.

Fermentation and quality of yellow pigments from golden brown rice solid culture by a selected Monascus mutant.
Abstract
A single peak (λmax 370) yellow pigment-producing mutant derived from Monascus sp. TISTR 3179 was used for the pigment production in solid rice culture. Various factors affecting yellow tones were investigated. Hom-mali rice variety was the best amongst five Thai local varieties used for fungus culture. It was also better than corn, mungbean, soybean, potato, sweet potato, or cassava tubers. The moisture content and temperature were the key environmental factors affecting the color tones of creamy, tangerine, and golden brown rice solid cultures. The golden brown rice culture gave the highest yel...

Purification and characterization of the extracellular laccase produced by Trametes polyzona WR710–1 under solid‐state fermentation
Abstract
Laccase from Trametes polyzona WR710–1 was produced under solid‐state fermentation using the peel from the Tangerine orange (Citrus reticulata Blanco) as substrate, and purified to homogeneity. This laccase was found to be a monomeric protein with a molecular mass of about 71 kDa estimated by SDS–PAGE. The optimum pH was 2.0 for ABTS, 4.0 for L‐DOPA, guaiacol, and catechol, and 5.0 for 2,6‐DMP. The Km value of the enzyme for the substrate ABTS was 0.15 mM, its corresponding Vmax value was 1.84 mM min−1, and the kcat/Km value was about 3960 s−1 mM−1. The enzyme activity was stable betwee...

In Vitro and In Vivo Anti-Tobacco Mosaic Virus Activities of Essential Oils and Individual Compounds.
Abstract
Essential oils are increasingly of interest for use as novel drugs acting as antimicrobial and antiviral agents. In the present study, we report the in vitro antiviral activities of 29 essential oils, extracted from Chinese indigenous aromatic plants, against the tobacco mosaic virus (TMV). Of these essential oils, those oils from ginger, lemon, tea tree, tangerine peel, artemisia, and lemongrass effected a more than 50% inhibition of TMV at 100 microng/ml. In addition, the mode of antiviral action of the active essential oils was also determined. Essential oils isolated from artemisia ...

Induced bronchospasm after handling of orange flavedo (zest)
Orange (Citrus sinensis) fruit and juice are widely consumed in Europe. Oranges belong to the Rutaceae family, members of which are found in warm regions worldwide and also include limes, lemons, tangerines, and grapefruit. Despite their wide consumption, sensitization to Rutaceae is rare, but the diagnosis should not be overlooked. (Source: Journal of Allergy and Clinical Immunology)
