Results We assessed 113 challenges (35 peanut, 28 egg, 12 tree nut, 11 milk, 27 other). There were 29 failures (22 objective, 7 subjective). Among objective challenge failures, 4/7 cashew (57%), 10/35 (29%) peanut, and 6/28 egg (21%) failed. There were no failed milk challenges. Most (79%) failed peanut/cashew challenges occurred at doses ≤1.0g while 50% of failed egg challenges were final dose...

Allergy to peanut is a severe and life altering health problem faced by increasing numbers of children and adults. It affects 1 to 2% of children in Westernised countries. Peanut allergy is the leading cause of anaphylaxis and death due to food allergy. Over the last 10-15 years the prevalence of peanut allergy has doubled in the United clinical experience of local allergists indicates a rising...

Food allergy is a major health concern in industrialized countries, affecting approximately 3.9% of children. Peanut allergy is one of the most common forms of food allergy, with approximately 3 million Americans reporting allergy to peanuts or tree nuts, and the prevalence appears to be increasing. Peanut and tree nut allergy account for the vast majority of life-threatening or fatal allergic ...

The peanut is a valuable seed from the legume Arachis hypogaea, which is largely produced in India, China, and the United States for human consumption as a whole seed, extracted oil, peanut butter, or protein-enhancing ingredient. Worldwide, peanuts are mostly used to produce highquality edible oil. In the United States, the majority of the crop is consumed in whole seed form or used for peanut...

The purpose of this study was to evaluate the occurrence of lipid oxidation in peanut (Arachis hypogaea L) seeds which were heated by microwave irradiation. Peanut seeds were exposed to microwaves for 0, 2.5, 3.5, 4.5, 5.5 and 6.5 min at frequency of 2,450 MHz, 450 watts microwave oven. The quality characteristics of peanut seed (moisture content and color values), extracted peanut oils (PV, TB...

Methyleugenol is naturally occurring substance in oils and fruits and in various foods as flavoring agent. Effect of this methyleugenol in inhibiting A. flavus colonization and aflatoxin production on peanut pods and kernels has been studied. Spray of methyleugenol (0.5%) on peanut pods and kernels checked the colonization of A. flavus and aflatoxin synthesis. This chemical can be used as both ...

A nanopore immunosensor is demonstrated for peanut protein Ara h1, a common food allergen. This biosensor is constructed by immobilizing the antibody to peanut protein Ara h1 within Au-coated pores of commercial nanoporous polycarbonate membranes. Peanut protein Ara h1 is detected as the change in the pore conductivity as the pores are partially obscured by antigen binding. Control experimentsw...

BACKGROUND/AIMS Allergen absorption by epithelia may play an important role in downstream immune responses. Transport mechanisms that can bypass Peyer's patches include transcellular and paracellular transport. The capacity of an allergen to cross via these means can modulate downstream processing of the allergen by the immune system. The aim of this study was to investigate allergen-epithelial...

Aflatoxin contamination is a major economic and food safety concern for the peanut industry that largely could be mitigated by genetic resistance. To screen peanut for aflatoxin resistance, ten genotypes were infected with a green fluorescent protein (GFP)-expressing Aspergillus flavus strain. Percentages of fungal infected area and fungal GFP signal intensity were documented by visual ratings ...

peanuts, an oilseed crop, contain about 46% oil. the peanut shell can be used as fuel or pallets and its dry matter as feedstuff. the whole pods consist of 1-6 kernels. shelling is done at harvest time when the pod moisture content is 5-10%. in this research, a peanut sheller was designed and developed to separate the shell from the pod. the sheller included a hopper, sheller cylinder, concave,...
