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 […]
Identification and analysis of the FAD gene family in walnuts (Juglans regia L.) based on transcriptome data.
Background: Walnut kernels contain a large amount of unsaturated fatty acids, such as linoleic acid and linolenic acid, which are essential fatty acids for humans and have important effects on growth and health. The main function of fatty acid desaturase (FAD), which is widely distributed in organisms, is to remove hydrogen from carbon chains in the […]
A comparison of ground-based air-blast sprayer and aircraft application of fungicides to manage scab in tall pecan trees.
Pecan scab (caused by Venturia effusa) is a destructive disease of pecan in the southeastern United States. Susceptible cultivars must be sprayed with fungicide every 10 to 21 days to ensure yield and kernel quality. Fungicide is most often applied using large orchard air-blast sprayers. Pecan trees grow tall, and air-blast sprays result in a gradient […]
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 […]
Spray drying and storage of probiotic enriched almond milk: probiotic survival and physicochemical properties.
Background: The combination of the nutritional profile of almond milk with the benefits of probiotic bacteria are an interesting development to cover the demand of sustainable and health-promoting food. Almond milk inoculated with probiotic Lactobacillus plantarum (ATCC 8014) was spray dried. Physicochemical characterization of almond raw material, almond milk and powders were carried out within this […]
Advancing Agricultural Production With Machine Learning Analytics: Yield Determinants for California’s Almond Orchards.
Agricultural productivity is subject to various stressors, including abiotic and biotic threats, many of which are exacerbated by a changing climate, thereby affecting long-term sustainability. The productivity of tree crops such as almond orchards, is particularly complex. To understand and mitigate these threats requires a collection of multi-layer large data sets, and advanced analytics is […]
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 […]
Identification of cross‐reactive allergens in cashew‐and pistachio‐allergic children during oral immunotherapy.
It has been estimated that around 8% of the children in the U.S. suffer from food allergy and of those, 40% are allergic to multiple foods. Among tree nuts, allergies to pistachios are common in those with cashew nut allergy and multiple homologous allergenic components are shared between the two nuts. Three major allergens from […]
