LAMP-based group specific detection of aflatoxin producers within Aspergillus section Flavi in food raw materials, spices, and dried fruit using neutral red for visible-light signal detection.
Abstract
Aflatoxins can be produced by 21 species within sections Flavi (16 species), Ochraceorosei (2), and Nidulantes (3) of the fungal genus Aspergillus. They pose risks to human and animal health due to high toxicity and carcinogenicity. Detecting aflatoxin producers can help to assess toxicological risks associated with contaminated commodities. Species specific molecular assays (PCR and LAMP) are available for detection of major producers, but fail to detect species of minor importance. To enable rapid and sensitive detection of several aflatoxin producing species in a single analysis, a nor1 gene-sp...

Postharvest dehydration induces variable changes in the primary metabolism of grape berries
Publication date: March 2018 Source:Food Research International, Volume 105 Author(s): Artur Conde, Flávio Soares, Richard Breia, Hernâni Gerós Postharvest dehydration causes changes in texture, color, taste and nutritional value of food due to the high temperatures and long drying times required. In grape berries, a gradual dehydration process is normally utilized for raisin production and for making special wines. Here we applied a raisin industry-mimicking dehydration process for eleven days at 50°C to intact berry clusters from cv. Sémillon plants, and a set of molecular, cellular and biochemical analyses we...

Using Electromagnetic Articulography to Measure Denture Micromovement during Chewing with and without Denture Adhesive
ConclusionsObservations of denture movement using the Wave EMA System were able to differentiate systematically between adhesive treatment and no‐adhesive treatment for denture micromovements during different chewing challenges. Use of adhesive was associated with statistically significant reductions in denture micromovements for hard, sticky, and tough foods as measured with both distance and threshold endpoints.

Dried fruit and dental health – how strong is the evidence?
Abstract
Children's dental health in England has shown improvement in recent decades. However, 24.7% of 5 year‐olds have obvious decay, with the average number of affected teeth being 3.4, and tooth decay is the most common reason for hospital admissions in 5–9 year‐olds. Public Health England advises that foods and drinks containing free sugars are limited because of the increased risk of dental caries associated with frequent intakes. Although dried fruit contains more sugars than fresh fruit by weight due to the dehydration process, the portion size of dried fruit is 30 g compared with 80 g for fresh fruit. Addi...

Association of raisin consumption with nutrient intake, diet quality, and health risk factors in US adults: National Health and Nutrition Examination Survey 2001-2012.
In conclusion, raisin consumption was associated with better nutrient intake, diet quality, and weight parameters, and with lower risk of being obese and having metabolic syndrome in US adults.

Senses
Scent of newborn wrapped in a knitted blanket
Watch her grow, first day of school
Track her on the playground, never a moment of rest
Chew on oatmeal raisin cookies baked together
Shut our eyes for hide-and-seek
Hear her cry, she skinned her knees
Cheer as she scores a goal
Carry her when she falls down
Run to catch up, now she's too fast
Clap and celebrate, it's graduation
Point to her suitcase, she is ready to pack
Hug her tight and hope she comes back
She walks to the gate, college here she comes
Reflex to wake her up for school, no longer there
Home feels off-balance, too quiet
Sharp pain from the tough goodbye
Cold sh...

Authors: Han JM, Lim HN, Jung HJ
Abstract
Specific inhibition of angiogenesis has been considered a powerful strategy for the treatment of cancer and other angiogenesis-related human diseases. Hovenia dulcis Thunb., Japanese raisin tree or Oriental raisin tree, is a hardy tree found in Asia, Eastern China and Korea and has been known to possess various biological activities, including antifatigue, antidiabetic, neuro...

Targeted screening and safety evaluation of 276 agrochemical residues in raisins using buffered ethyl acetate extraction and liquid chromatography-tandem mass spectrometry analysis.
Abstract
A buffered ethyl acetate extraction method was optimized and validated in raisin matrix to monitor 276 pesticides by liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis. The final method involved homogenization of raisinsalong with water 1:1 raisins: water followed by extraction using ethyl acetate (10 mL/10 g raisins homogenate in presence of 0.1 mL acetic acid, 0.5 g sodium acetate and 10 g sodium sulfate, and cleanup by dispersive solid phase extraction with primary secondary amine sorbent (25 mg/5 mL extract). 276 pesticides were estimated within 20 min of chromatographic...

Highly sensitive method for aldehydes detection: Application to furfurals analysis in raisin and bovine milk powder.
Abstract
A pre-column fluorescent derivatization method based on nitrone formation has been applied to determine furfurals (e.g. furfural (F), 5-methyfurfural (5-MF) and 5-hydroxymethylfurfural (5-HMF)) in food samples for the first time. An N-substituted hydroxylamine reagent 4-((hydroxyamino)butyl)-7-hydroxycoumarin (HAHC) was used to react with the aldehyde group of furfurals to form stable nitrone derivatives with high fluorescence intensities. The reactions proceeded under mild conditions in 30 min with high derivatization yields (>93%). A baseline-separation of three furfurals derivatives was sub...

Raisins and Currants as Conventional Nutraceuticals in Italian Market: Natural Occurrence of Ochratoxin A
This study reports the occurrence of Ochratoxin A (OTA) and associated fungal contamination in 35 samples of dried vine fruits imported in the European community potentially used for the development of new nutraceutical supplements. High pressure liquid chromatography analysis identified 18 samples as contaminated by OTA with an average level of 2.6 μg/kg. OTA was measured in 4 samples of currants (mean value of 6.6 μg/kg) and 13 samples of raisins (mean value of 1.4 μg/kg). In one sample of currants and one of raisins from Turkey OTA exceeded the limits set by European Commission of 10 μg/kg, being contaminated with 1...
