Inhibition of Aflatoxin Formation in Aspergillus Species by Peanut (Arachis hypogaea) Seed Stilbenoids in the Course of Peanut-Fungus Interaction.

Common soil fungi, Aspergillus flavus and Aspergillus parasiticus, are opportunistic pathogens that invade preharvest peanut seeds. These fungi often produce carcinogenic aflatoxins that pose a threat to human and animal health through food chains and cause significant economic losses worldwide. Detection of aflatoxins and further processing of crops are mandated to ensure that contaminated agricultural […]

Sensory Characterization of Dominant Malawi Peanut Varieties After Roasting.

Although sensory appeal influences peanut consumption, peanut varieties are mostly selected based on agronomic traits. As a result, the sensory properties of peanut varieties, especially in southern Africa, are not known. Therefore, the primary objective of the study was to determine the sensory properties of the Malawi peanut varieties and the volatile compounds associated with roasted peanut flavor. Six dominant Malawi peanut varieties (Chalimbana, CG7, Nsinjiro, Kakoma, […]

Seafood Flavor Perception, Liking, Emotion, and Purchase Intent of Coated Peanuts as Affected by Coating Color and Hydrolyzed Squid Peptide Powder.

This study evaluated effects of green compared with brown coating colors and varying levels of hydrolyzed squid peptide powder (HSP) on seafood flavor perception, sensory liking, emotions, and purchase intent (PI) of coated peanuts. Dried squid head was enzymatically hydrolyzed to produce HSP, which was then incorporated into peanut coating material at 0%, 0.89%, 1.78%, and 2.66% […]

A Natural Peanut Edible Coating Enhances the Chemical and Sensory Stability of Roasted Peanuts.

This study aims to assess the enhancement of the chemical and sensory properties of roasted peanuts during storage, through the application of high-protein defatted peanut flour (DPF) coatings incorporated with and without antioxidants. The control sample without coating, packed in normal atmosphere (control), showed the highest conjugated dienes (CD) increment (from 1.17 on day 0 to 3.60 […]

Selected nutrients and anti‐nutrients in peanut cultivars harvested in Brazil.

BACKGROUND: There are more than 30 peanut cultivars registered in Brazil. However, there is no published data about the content of nutrients and anti-nutrients even in the most commercially important ones. Therefore, our objective was to characterize commercial peanut cultivars harvested in Brazil by determining proximate and fatty acid compositions and contents of selected minerals […]

Comparison of recovery and immunochemical detection of peanut proteins from differentially roasted peanut flour using ELISA.

The effect of heat on extractability and immunoreactivity of proteins from roasted peanut flours and whole peanuts was evaluated using two general protein assays and six commercial peanut ELISA kits, respectively. The highest amount of protein was recovered from roasted peanuts with all ELISAs, while recovery showed a decrease with increasing levels of roasting of the peanut flours. Only the Morinaga […]

Timing of Food Introduction and the Risk of Food Allergy.

Given that the prevalence of pediatric IgE-mediated food allergies (FA) has followed a substantive increase in recent decades, nowadays, a research challenge is to establish whether the weaning strategy can have a role in FA prevention. In recent decades, several studies have demonstrated that delayed exposure to allergenic foods did not reduce the risk of […]

Clinical Factors Associated with Peanut Allergy in a High Risk Infant Cohort.

BACKGROUND: Prognostication of peanut allergy (PNA) is relevant for early interventions. We aimed to determine baseline parameters associated with development of PNA in 3-15 month olds with likely egg and/or milk allergy, and/or moderate-severe atopic dermatitis (AD) and a positive egg/milk skin prick test (SPT), but no known PNA. METHODS: The primary endpoint was PNA […]

Current management and use of oral immunotherapy in the United States for patients with peanut allergy.

BACKGROUND: Peanut allergy is a major health burden in the United States. Treatment is limited to avoidance and acutereaction management. No drug or medical product is approved for use as a peanut oral immunotherapy (POIT) agent. OBJECTIVE: To examine peanut allergy diagnosis and treatment, peanut challenge protocols, nonpublished POIT approaches, POIT practice requirements and logistical […]
