Maximizing Phenolics; Antioxidants and Sensory Acceptance of UV and Ultrasound Treated Peanuts
The effects of varying doses of UV and ultrasound (US); and incubation times at 25°C on total phenolics (TP); antioxidant capacity by two methods; trolox equivalent antioxidant capacity (TEAC) and oxygen radical absorbance capacity (ORAC) and sensory overall acceptance (OA) of treated peanuts were investigated. Optimum process parameters for UV and US were determined using […]
Peanut Outlook: Impacts of the 2008-09 Foodborne Illness Outbreak Linked to Salmonella in Peanuts
Between January and April 2009; a foodborne illness outbreak linked to Salmonella resulted in one of the largest food safety recalls ever in the United States. The source of the outbreak was linked to one peanut processor handling less than 2 percent of the U.S. peanut supply; but the scope of the recalls was magnified […]
Biocontrol of Aspergillus flavus on peanut kernels by use of a strain of marine Bacillus megaterium
A strain of marine Bacillus megaterium isolated from the Yellow Sea of East China was evaluated for its activity in reducing postharvest decay of peanut kernels caused by Aspergillus flavus in in vitro and in vivo tests. The results showed that the concentrations of antagonist had a significant effect on biocontrol effectiveness in vivo: when […]
Thermal inactivation of Salmonella in peanut butter
The objective of this study was to determine the rates of thermal inactivation of three Salmonella Tennessee strains in peanut butter associated with an outbreak and to compare them to the rates of inactivation of Salmonella strains of other serotypes (Enteritidis; Typhimurium; and Heidelberg) (SSOS) and of clinical isolates of Salmonella Tennessee from sporadic cases […]
Food Allergy Among Children in the United States
Objectives: The goals were to estimate the prevalence of food allergy and to describe trends in food allergy prevalence and health care use among US children. Methods: A cross-sectional survey of data on food allergy among children
Roast effects on the hydrophilic and lipophilic antioxidant capacities of peanut flours; blanched peanut seed and peanut skins
Hydrophilic and lipophilic oxygen radical antioxidant capacity (H&L-ORAC) of peanut flours; blanched peanut seed; and peanut skins were characterized across a range of roast intensities. H-ORAC ranged from 5910 to 7990; 3040 to 3700 and 152;290 to 209;710 µmoles Trolox/100 g for the flours; seed; and skins; respectively. H-ORAC increased linearly with darker seed color […]
Oleic acid and peanut oil high in oleic acid reverse the inhibitory effect of insulin production of the inflammatory cytokine TNF-alpha both in vitro and in vivo systems
BACKGROUND: Chronic inflammation is a key player in pathogenesis. The inflammatory cytokine; tumor necrosis factor-alpha is a well known inflammatory protein; and has been a therapeutic target for the treatment of diseases such as Rheumatoid Arthritis and Crohn's Disease. Obesity is a well known risk factor for developing non-insulin dependent diabetes melitus. Adipose tissue has […]
Food Allergy Herbal Formula-2 silences peanut-induced anaphylaxis for a prolonged posttreatment period via IFN-gamma-producing CD8+ T cells
BACKGROUND: Food allergy is a serious and sometimes fatal condition for which there is no cure. We previously reported that Food Allergy Herbal Formula (FAHF)-2) protected peanut-allergic mice against anaphylactic reactions as long as 4 weeks posttherapy. This formula is now in clinical trials in the United States. OBJECTIVE: We sought to determine whether FAHF-2-mediated […]
Early consumption of peanuts in infancy is associated with a low prevalence of peanut allergy
BACKGROUND: Despite guidelines recommending avoidance of peanuts during infancy in the United Kingdom (UK); Australia; and; until recently; North America; peanut allergy (PA) continues to increase in these countries. OBJECTIVE: We sought to determine the prevalence of PA among Israeli and UK Jewish children and evaluate the relationship of PA to infant and maternal peanut […]
Successful oral tolerance induction in severe peanut allergy
Background: Peanut allergy is common; potentially severe and rarely resolves causing impaired quality of life. No disease-modifying treatment exists and there is therefore a need to develop a therapeutic intervention. Aims of the study: The aim of this study was to investigate whether peanut oral immunotherapy (OIT) can induce clinical tolerance to peanut protein. Methods: […]
