Development of a multiplex real-time PCR for determination of apricot in marzipan using the PLEXOR® System.
Marzipan is a confectionary which is mostly offered in form of filled chocolate, pralines or pure. According to the German guidelines for oil seeds only almonds, sugar and water are admitted ingredients of marzipan. A product very similar in taste is persipan which is used in the confectionary industry because of its stronger flavor. For […]
Identification and Characterization of Ana o 3 Modifications on Arginine Residue-111 in Heated Cashew Nuts.
Raw and roasted cashew nut extracts were evaluated for protein modifications by mass-spectrometry. Independent modifications on the Arg-111 residue of Ana o 3 were observed in roasted but not raw cashew nuts. The mass changes of 72.0064 or 53.9529 Da are consistent with formation of carboxyethyl and hydroimidazolone modifications at the Arg-111 residue. These same […]
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 […]
Physico-chemical characteristics and fungal profile of four Saudi fresh date (Phoenix dactylifera L.) cultivars.
Physico-chemical and microbial analyses of four commercial fresh date cultivars (Sukari, Barhi, Khalas and Rothana) grown in Saudi Arabia were evaluated. Colorimetric assay indicated that Sukari had the highest total sugar content of 13.21g/100gFW while the lowest was in Rothana with 7.96g/100gFW. Total phenolic content (TPC) ranged from 76.74 to 122.20mgGAE/100gFW in Barhi and Rothana […]
Effects of Sulfur Dioxide Concentration on Organic Acids and β-Carotene in Dried Apricots During Storage.
The effects of various sulfur dioxide (SO2) concentrations (0, 451, 832, 1594, 2112 and 3241mg/kg) on the profiles and contents of organic acids (OAs) and β-carotene in sulfured dried apricots (SDAs) were investigated during storage at 4, 20 and 30°C for 379days. In all samples, four OAs [malic acid (MA), citric acid (CA), succinic acid […]
Food processing and structure impact the metabolizable energy of almonds.
The measured metabolizable energy (ME) of whole almonds has been shown to be less than predicted by Atwater factors. However, data are lacking on the effects of processing (roasting, chopping or grinding) on the ME of almonds. A 5-period randomized, crossover study in healthy individuals (n = 18) was conducted to measure the ME of […]
New model for colour kinetics of plum under infrared vacuum condition and microwave drying
Background. Quality of dried foods is affected by the drying method and physiochemical changes in tissue. The drying method affects properties such as colour. The colour of processed food is one of the most important quality indices and plays a determinant role in consumer acceptability of food materials and the processing method. The colour of […]
Epicutaneous immunotherapy for the treatment of peanut allergy in children and young adults. Journal of Allergy and Clinical Immunology
BACKGROUND: Peanut allergy is common, life-threatening, and without therapeutic options. We evaluated peanut epicutaneous immunotherapy (EPIT) by using Viaskin Peanut for peanut allergy treatment. OBJECTIVE: We sought to evaluate the clinical, safety, and immunologic effects of EPIT for the treatment of peanut allergy. METHODS: In this multicenter, double-blind, randomized, placebo-controlled study, 74 participants with peanut […]
Desensitization for Peanut Allergies in Children.
Immunotherapy for peanut allergy has been an exploding topic of study within the last few years. Sublingual, epicutaneous, and oral immunotherapy are being investigated and show promise in the treatment of peanut allergy. Oral immunotherapy has shown the most clinical benefit; however, sublingual and epicutaneous immunotherapy appear to have the most favorable safety profiles. Most […]
Early introduction of food reduces food allergy–Pro.
Over the past two decades we have been debating the question of whether the age of commencement of complementary feeding affects the risk of developing food allergy. We ate up the notion that delayed introduction of more allergenic foods in early childhood, would help overcome the increasing rates of food allergy, then we promptly spat […]
