AFLA-PISTACHIO: Development of a Mechanistic Model to Predict the Aflatoxin Contamination of Pistachio Nuts.
In recent years, very many incidences of contamination with aflatoxin B1 (AFB1) in pistachio nuts have been reported as a major global problem for the crop. In Europe, legislation is in force and 12 μg/kg of AFB1 is the maximum limit set for pistachios to be subjected to physical treatment before human consumption. The goal of the […]
Ascophyllum Nodosum And Salicylic Acid Mitigate Effects Of Summer Stress Improving Hazelnut Quality.
Background: Difference strategies are needed to mitigate the negative impact or to increment fruit quality. The effect of spraying Kaolin (K), Ascophyllum nodosum (An) and Salicylic acid (SA), in trees with and without irrigation, on quality and sensorial attributes of hazelnut (Grada de Viseu cultivar) was investigated during two consecutive years (2016 and 2017) in a […]
Evaluation of the effect of label attributes over the purchase intention of a cashew nut functional beverage using conjoint analysis.
The package label is an important factor to be evaluated, for constituting the first contact of the product with the consumer, which may exert influence on the purchase intention. Thus, this study identified and evaluated the importance of front label attributes of a new functional beverage made from cashew nut added with mango juice on […]
Influence of Post‐Harvest Moisture on Roasted Almond Shelf Life and Consumer Acceptance.
Background: Sweet almonds (Prunus dulcis) harvest weights have significantly increased to meet consumer demand and now exceed processing facility capabilities. Crops are stockpiled for longer periods of time increasing the probability of moisture exposure. Wet almonds can be mechanically dried prior to processing; however, it is unclear how this practice influences lipid oxidation, shelf-life and consumer […]
Non-Targeted Detection of Adulterants in Almond Powder Using Spectroscopic Techniques Combined with Chemometrics.
Methods that combine targeted techniques and chemometrics for analyzing food authenticity can only facilitate the detection of predefined or known adulterants, while unknown adulterants cannot be detected using such methods. Therefore, the non-targeted detection of adulterants in food products is currently in great demand. In this study, FT-IR and FT-NIR spectroscopic techniques were used in […]
Growth and survival of foodborne pathogens during soaking and drying of almond (Prunus dulcis) kernels.
The practice of soaking almonds prior to consumption is popular both commercially and at home. The food safety implications of soaking almonds was investigated through analysis of blogs and videos (n = 85 recipes) to identify both the reasons for soaking almonds and the common practices employed. Among the recipes analyzed, the most common reasons […]
Redomesticating almond to meet emerging food safety needs.
Almond is a desirable and high-quality food source where the presence of nut allergens and a vulnerability to aflatoxin and Salmonella contamination represent threats to consumer safety. In 2019, over 1 billion kg. of almonds, representing over 80% of the world total, were produced in California from a relatively few varieties with a very narrow […]
Effects of deficit irrigation, rootstock, and roasting on the contents of fatty acids, phytoprostanes, and phytofurans in pistachio kernels.
Pistachio (Pistacia vera L.) is a drought-tolerant specie grown under the semiarid conditions of the Mediterranean basin. For this reason, it is essential to make an exhaustive quantification of yield and quality benefits of the kernels because the regulated deficit irrigation will allow significant water savings with a minimum impact on yield, while improving kernel […]
Natural Variation of Hazelnut Allergenicity: Is There Any Potential for Selecting Hypoallergenic Varieties?.
Hazelnuts (Corylus avellana L.) have an important role in human nutrition and health. However, they are a common cause of food allergy. Due to hazelnut varietal diversity, variety-dependent differences in the IgE-binding properties may be suspected, which could allow therapeutic strategies based on the use of hypoallergenic varieties to induce desensitization. In a proteogenomic approach, we […]
Immunoglobulin E-Binding Pattern of Canadian Peanut Allergic Children and Cross-Reactivity with Almond, Hazelnut and Pistachio.
Peanut allergic individuals can be both co-sensitized and co-allergic to peanut and tree nuts. At the moment, standard diagnostic approaches do not always allow differentiation between clinically relevant sensitization and nonsignificant cross-reactions, and the responsibility of each allergen remains unclear. The objective of this study was therefore to determine a peanut sensitization profile in a […]
