Potential health benefits and quality of dried fruits: goji fruits, cranberries and raisins.

Dried fruits are important snacks and additives to other foods due to their taste and nutritional advantages. Therefore there is an important goal to control the quality of the food on the market for consumer's safety. Antioxidant activity of goji fruits (Lycium barbarum), cranberries (Vaccinium macrocarpon and oxycoccus) and raisins (Vitis vinifera) were studied using […]

Exploratory analysis of CD63 and CD203c expression in basophils from hazelnut sensitized and allergic individuals.

BACKGROUND: Sensitization to hazelnut (HN) is frequent and requires clarification to determine whether this sensitization is clinically relevant. The aim of this study was to investigate basophil activation profiles in HN-sensitized and allergic subjects. METHODS: Basophil activation was determined by flow cytometric analyses of CD63 and CD203c expression using several HN allergen concentrations. Depending on […]

Streamlining the analytical workflow for multiplex MS/MS allergen detection in processed foods

Allergenic ingredients in pre-packaged foods are regulated by EU legislation mandating their inclusion on labels. In order to protect allergic consumers, sensitive analytical methods are required for detect allergen traces in different food products. As a follow-up to our previous investigations, an optimized, sensitive, label-free LC-MS/MS method for multiplex detection of five allergenic ingredients in […]

Advances in food allergy in 2015.

This review highlights research advances in food allergy that were published in the Journal in 2015. The world of food allergy research continues to rapidly accelerate, with increasing numbers of outstanding submissions to the Journal. In 2015, important studies on the epidemiology of food allergy were published, suggesting differential rates of food allergy in specific […]

B-vitamins, carotenoids and α-/γ-tocopherol in raw and roasted nuts

The concentrations of B-vitamins, carotenoids and tocopherols in nuts may differ between species and might be influenced by roasting. Thiamine, riboflavin, pyridoxine, lutein, zeaxanthin, β-carotene and α-/γ-tocopherol were determined in different varieties of raw and roasted nuts using HPLC (fluorescence/UV-vis detection). The analysis revealed remarkable concentrations of thiamine and pyridoxine in pistachios (57%, 79% of […]

Maillard Reaction and Caramelization during Hazelnut Roasting: A multiresponse kinetic study

A comprehensive kinetic model indicating the elementary steps of Maillard reaction and caramelization during hazelnut roasting was proposed based on a multi-response kinetic modeling approach. Changes in the concentrations of sucrose, fructose, glucose, amino acids, 3-deoxyglucosone, 1-deoxyglucosone, 3,4-dideoxyglucosone, glyoxal, methylglyoxal, dimethylglyoxal, and 5-hydroxymethylfurfural were examined in hazelnuts during roasting at 150, 160 and 170°C for […]

Prevalence and Amounts of Salmonella Found on Raw California Inshell Pistachios.

After harvest, pistachios are hulled with mechanical abrasion and then separated in a float tank containing water; the nuts that float (∼15%; floaters) and those that sink (∼85%; sinkers) are dried and stored separately. To determine the prevalence of Salmonella in pistachios, a total of 3,966 samples (1,032 floaters and 2,934 sinkers) were collected within […]
