Origin Traceability of Peanut Kernels Based on Multi-Element Fingerprinting Combined With Multivariate Data Analysis.

Background: Multi-elements have been widely used to identify the geographical origins of various agricultural products. The objective of this study was to investigate the feasibility of identifying the geographical origins of peanut kernels at different regional scales by using the multi-element fingerprinting technique. The concentrations of 20 elements (B, Mg, P, K, Ca, etc.) were determined […]

Bridging Fe3O4@ Au Nanoflowers and Au@ Ag Nanospheres with Aptamer for Ultrasensitive SERS Detection of Aflatoxin B1.

Aflatoxin B1 (AFB1) as the most toxic mycotoxin in contaminated food can greatly threaten human health, and sensitive and selective detection of AFB1 is thus highly desired. An ultrasensitive surface-enhanced Raman spectroscopy (SERS) aptasensor was developed for AFB1 detection in peanut oil samples. SH-cDNA modified Fe3O4@Au nanoflowers acted as capture probes, SH-Apt modified Au@Ag nanospheres […]

Modification of a Predictive Model to Include the Influence of Fat Content on Salmonella Inactivation in Low-Water-Activity Foods.

Low-water-activity (aw) foods (including those containing fat) are often implicated in outbreaks of Salmonella spp. The influence of fat content on survival in foods such as peanut butter remains unclear. Certain Salmonella serovars can survive for long periods in harsh temperatures and low moisture conditions. The objective of this study was to determine the influence […]

Effect of Drying Temperatures on the Peanut Quality during Hot Air Drying.

Peanuts are usually with high moisture after harvest and must be dried to prevent mildew. Hot air drying is the most commonly used method for peanut drying. The purpose of this study was to evaluate the drying temperatures on the peanut qualities. In this paper, fresh peanuts were dried with solar radiation (control group) and […]

Prevalence of Food Sensitization and Food Allergy in Children across Europe.

Background: For adults, prevalence estimates of food sensitization (FS) and food allergy (FA) have been obtained in a standardized manner across Europe. For children, such estimates are lacking. Objectives: To determine prevalence of self-reported FA, FS, probable FA (symptoms plus IgE-sensitization), and challenge-confirmed FA in European school-age children. Methods: Data on self-reported FA were collected through a screening […]

Peanut Oral Immunotherapy: a Current Perspective.

Purpose of the review: Peanut oral immunotherapy (OIT) is one of the most studied experimental therapies for food allergy. With the recently FDA-approved peanut product, Palforzia, the goal of this article is to review the most recent data from clinical trials, discuss recent trends, and anticipate future developments. Recent findings: The latest research suggests that peanut OIT […]

Ara h 2 is the dominant peanut allergen despite similarities with Ara h 6.

Background: Ara h 2 specific-IgE (sIgE) is to date the best serologic marker to diagnose peanut allergy. Ara h 6 shares ∼60% sequence identity and multiple epitopes with Ara h 2. Objective: To assess the diagnostic utility and relative importance of Ara h 2 and Ara h 6 in peanut allergy. Methods: A cohort (n=100) of peanut allergic […]

Tree Nuts and Peanuts as a Source of Natural Antioxidants in our Daily Diet.

Tree nuts and peanuts are healthful foods with a track record of helping to reduce the incidence of chronic diseases, most notably cardiovascular disease. At the point of consumption, all nuts contain low moisture and ≥ 50% lipid contents, but this is where similarities end. The levels of key nutrients and bioactives including vitamin C, […]

Advances in Crop Improvement and Delivery Research for Nutritional Quality and Health Benefits of Groundnut (Arachis hypogaea L.).

Groundnut is an important global food and oil crop that underpins agriculture-dependent livelihood strategies meeting food, nutrition, and income security. Aflatoxins, pose a major challenge to increased competitiveness of groundnut limiting access to lucrative markets and affecting populations that consume it. Other drivers of low competitiveness include allergens and limited shelf life occasioned by low […]

Allergen Removal and Transfer Using Wiping and Cleaning Methods in Retail and Food Service Establishments.

Preventing the transfer of allergens from one food to another via food-contact surfaces in retail food environments is an important aspect of retail food safety. Existing recommendations for wiping and cleaning food-contact surfaces is mainly focused on preventing microorganisms such as bacteria and viruses from contaminating foods. The effectiveness of these wiping and cleaning recommendations […]
