Effect of Date (Phoenix dactylifera L.) Pits on the Shelf Life of Beef Burgers.
A new ingredient from date palm coproducts (pits) was obtained and tested as a preservative in burgers. Different concentrations of date pit (0%, 1.5%, 3%, and 6%) were added to beef burgers, and its effect on the safety and quality was evaluated during 10 days of storage. The incorporation of date pit was able to […]
Aflatoxin contaminated degree detection by hyperspectral data using band index.
Aflatoxin is a highly toxic and carcinogenic substance with fluorescence characteristic. To explore the feasibility of detection the degree of aflatoxin contamination using hyperspectral imaging technology, we proposed a machine learning detection method based on support vector machine (SVM) combining band index and narrow band. First, five concentrations of aflatoxin solutions (10ug/L, 20ug/L, 50ug/L, 100ug/L […]
Development of an Escherichia coli-based Electrochemical Biosensor for Mycotoxin Toxicity Detection.
Mycotoxin contamination in food and feed is a global concern because mycotoxin contamination can cause both acute and chronic health effects in humans and animals. In the present work, an Escherichia coli-based biosensor is described for the toxicity assessment of aflatoxin B1 (AFB1) and zearalenone (ZEN). In this electrochemical biosensor, E. coli is used as the […]
Cashew nut and cashew apple: a scientific and technological monitoring worldwide review.
The cashew tree or Anacardium occidentale, a tropical tree native from Brazil, was introduced to Asia and Africa by European explorers in the sixteenth century. The world production of cashew nuts reached 4.89 million tons in 2016, with Vietnam being the largest producer of nuts. The cashew market is expected to remain strong due to high […]
Evaluation of Microwave and Ozone Disinfections on the Color Characteristics of Iranian Export Raisins through an Image Processing Technique.
Raisins are one of the most important Iranian export products but are threatened by various storage pests. Because of the disadvantages of fumigants, we evaluated alternative microwave and ozone methods for their disinfection and the side effects on raisin qualities. To perform microwave disinfection, the studied raisin samples were exposed to microwave powers of 450, […]
Analysis of multiclass pesticides in dried fruits using QuEChERS-gas chromatography tandem mass spectrometry.
In this work, three versions of the QuEChERS method (original, AOAC 2007.01 and CEN 15662) were evaluated for the extraction of 38 multiclass pesticides from a mixture of five dried fruits: (strawberry, blackberry, passion fruit, pineapple and grapes) prior to their gas chromatography tandem mass spectrometry analysis. Among them, the AOAC 2007.01 method provided the […]
DNA barcoding coupled with high‐resolution melting analysis for nut species and walnut milk beverage authentication.
Background: Walnut (Juglans regia L.) is one of the most widely cultivated nuts. Walnut milk beverage is very popular in China due to its nutritional value. However, adulterated walnut milk ingredients have been detected in the Chinese market. Peanut and soybean are sold at much lower prices than walnut and are reported as common adulterated species […]
The Inorganic Component as a Possible Marker for Quality and for Authentication of the Hazelnut’s Origin.
The inorganic component of hazelnuts was considered as a possible marker for geographical allocation and for the assessment of technological impact on their quality. The analyzed samples were Italian hazelnuts of the cultivar Tonda Gentile Romana and Turkish hazelnuts of the cultivars Tombul, Palaz and Çakildak. The hazelnuts were subjected to different drying procedures and different conservative methods. The concentration of […]
Critical review on proteotypic peptide marker tracing for six allergenic ingredients in incurred foods by mass spectrometry.
Peptide marker identification is one of the most important steps in the development of a mass spectrometry (MS) based method for allergen detection, since the robustness and sensitivity of the overall analytical method will strictly depend on the reliability of the proteotypic peptides tracing for each allergen. The European legislation in place issues the mandatory […]
Thermal processing of peanut impacts detection by current analytical techniques.
Recalls of spice containing products due to undeclared peanut have highlighted the importance of analytical methods in these foods. We examined the performance of peanut detection methods in cumin and garlic, focusing on quantitative ELISA. Although suitable for qualitative detection, accurate quantitation proved difficult. Roasting of peanut contaminants influenced ELISA results, with raw peanut over-detected […]
