Color and texture of low-calorie peanuts as affected by a new oil extraction process named "Mechanical Expression Preserving Shape Integrity" (MEPSI).
The current healthy life style pushed to develop and implement a novel efficient defatting process of high quality called "Mechanical Expression Preserving Shape Integrity" that conserved the sensory, color, textural, morphological and acceptability of partially defatted roasted peanuts. In this study, Response Surface Methodology was used to investigate the best extraction parameters (initial water content, […]
Influence of water activity on inactivation of Escherichia coli O157:H7, Salmonella Typhimurium and Listeria monocytogenes in peanut butter by microwave heating.
This study evaluated the efficacy of a 915 MHz microwave with 3 different electric power levels to inactivate three pathogens in peanut butter with different aw. Peanut butter inoculated with Escherichia coli O157:H7, Salmonella enterica serovar Typhimurium and Listeria monocytogenes (0.3, 0.4, and 0.5 aw) were treated with a 915 MHz microwave with 2, 4, […]
Advances in ultra-high performance liquid chromatography coupled to tandem mass spectrometry for sensitive detection of several food allergens in complex and processed foodstuffs.
Sensitive detection of food allergens is affected by food processing and foodstuff complexity. It is therefore a challenge to detect cross-contamination in food production that could endanger an allergic customer's life. Here we used ultra-high performance liquid chromatography coupled to tandem mass spectrometry for simultaneous detection of traces of milk (casein, whey protein), egg (yolk, […]
Experimental food allergy to peanut enhances the immune response to house dust mite in the airways of mice.
BACKGROUND: Food allergy has been associated with an increased risk for the development of allergic asthma. Asthma is a risk factor for the development of an anaphylactic response to food allergens. An immunological interplay between sensitization to different allergens in different compartments of the body might be involved. OBJECTIVE: To evaluate the immunological interplay between […]
Three peanut allergic/sensitized phenotypes with gender difference.
BACKGROUND: Peanut allergic reactions are heterogeneous ranging from mild symptoms to anaphylaxis. OBJECTIVE: Identify peanut allergic/sensitized phenotypes to personalize patient management. METHODS: A combined factor and cluster analysis was used to study the phenotypes of 696 patients diagnosed with peanut sensitization and enrolled in the MIRABEL survey. The method was first applied to the 247 […]
Simultaneous determination of six mycotoxins in peanut by High-performance Liquid Chromatography with Fluorescence detector.
BACKGROUND: Mycotoxins, which may contaminate peanut and peanut products, are responsible for many diseases to human beings. AflatoxinB1(AFB1), aflatoxinG1(AFG1), aflatoxinB2(AFB2), aflatoxinG2(AFG2), ochratoxin A(OTA) and zearalenone(ZEN) are considered the most relevant groups of mycotoxins found in food. This work aimed to develop a high-performance liquid chromatography with fluorescence detector(HPLC-FLD) combined with dispersive liquid-liquid microextraction(DLLME) method for […]
Nuts and their co-products: The impact of processing (roasting) on phenolics, bioavailability, and health benefits – A comprehensive review.
Nuts serve as important healthful snacks worldwide. They are highly desirable due to the presence of numerous essential macro- and micronutrients and health-promoting phenolic compounds (polyphenols). Nuts are usually consumed either as raw (natural) or as roasted. In addition, nuts and their co-products have been demonstrated to be rich sources of phenolic compounds that possess […]
Cerebrovascular and cognitive benefits of high-oleic peanut consumption in healthy overweight middle-aged adults.
OBJECTIVE: Peanuts contain bioactive nutrients beneficial for vascular function. This study investigated whether consumption of unsalted peanuts (with skins) would enhance cerebrovascular perfusion and cognitive performance. METHOD: In a randomized crossover trial, 61 volunteers (29 males/32 females, 65 ± 7 years, BMI 31 ± 4 kg/m2) consumed their habitual diet ± high-oleic peanuts (56-84 g/day), each for 12 weeks. Nutrient intakes, vascular and […]
Global perceptions of food allergy thresholds in 16 countries.
Background: Food allergy is a growing global health issue that affects daily life and food purchasing habits. Quality data on the global consumer perspective of food allergy is limited, particularly about thresholds and food labeling risk. Many individuals with food allergy are counseled that small amounts of allergen can potentially cause life-threatening reactions, and to […]
Food allergy in children.
Food allergy represents a highly up-to-date and continually increasing problem of modern man. Although being present in all ages, it most often occures in children aged up to three years. Sensitization most often occurs by a direct way, but it is also possible to be caused by mother's milk, and even transplacentally. Predisposition of inadequate […]
