The liquid-phase extraction combined with newly green extraction solvent named deep eutectic solvent has been widely used. In this work, a simple and fast analytical method based on deep eutectic solvent (DES) was developed for simultaneous determination of aflatoxin G1, B1, G2, and B2 in rice samples. With simple liquid-phase extraction, aflatoxins were quickly enriched into a tetramethylammonium chloride-malonic acid (n/n, 1:2) DES, accompanied with the enhancement of fluorescence intensity of...

Gluten is comprised of a set of wheat, barley, rye, and oat proteins, and it is widely present in the regular diet of the majority of western countries. However, gluten may cause serious health issues, such as celiac disease (CD). In barley, there are four hordein groups: γ-, B-, C-, and D-hordeins. Here, we describe a novel methodology to separate and characterize hordeins in barley grain and malt by capillary electrophoresis-mass spectrometry (CE-MS). Under the optimized conditions, characteri...

Phenolic compounds in olive oil are considered interesting, both for their effect on human wellness and for their role in the shelf life of olive oils. Many methods have been suggested for quantitative analysis of phenolic compounds in extra virgin olive oil, which determine that results are not always comparable; therefore, it is necessary to have simple, inexpensive, robust, and validated methods for official routine analyses. In this work, solid phase extraction (SPE) was carried out to isola...

In this work, a simple and rapid SPE–GC–FID method for simultaneous determination of free tocopherols and phytosterols in vegetable oils was developed. The use of this SPE approach for the extraction of naturally occurring tocopherols and phytosterols provides advantages such as simplicity, high speed, and ease of use. The whole method was validated, and the limits of detection of tocopherols and phytosterols were 0.05 and 0.03 mg/100 g of oil, respectively. The precisions for the determination ...

A matrix-assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF MS) method were established to detect Campylobacter jejuni and Listeria monocytogenes from a chicken farm and samples from commercial live chickens. Suspected isolates were pretreated and crystallized by matrix solutions consisting of ethanol, acetonitrile, and water with different proportions. The effect of matrix composition was evaluated by examining the differences in characteristic peak values and rela...

This work was carried out to develop a high-performance liquid chromatography tandem mass spectrometry method for simultaneous determination of 11 marker compounds in phytoestrogen-rich food and dietary supplements (raw materials and formulated products) prepared from various sources: soy, red clover, chastetree, hop, and flax. The method was fully validated and showed detection limits varying from 0.2 to 1.5 μg/mL, average recoveries ranging from 95 to 105%, and relative standard deviation valu...

In this study, a rapid and sensitive real-time loop-mediated isothermal amplification (Rti-LAMP) assay was developed for quantitative and evaluation of viable but non-culturable (VBNC) Salmonella. Four micrograms per milliliter of ethidium bromide monoazide (EMA) could significantly inhibit DNA amplification derived from dead cells in Rti-LAMP assays. The EMA-Rti-LAMP was used to monitor the culturable and VBNC Salmonella cells induced by 4 °C and − 20 °C, as direct fluorescence method (DEM) and...

Three sample preparation procedures were compared for a multi-residue analysis of pesticides in hops: (a) modified Hengel’s method based on extraction with acetonitrile in combination with clean-up on a C18 SPE column, (b) miniaturized Biendl’s method based on acetone extraction and PSA SPE sample clean-up, and (c) modified Quick, Easy, Cheap, Effective, Rugged, and Safe (QuEChERS) method which utilizes a specific mixture of three sorbents (PSA, C18, and Z-Sep) for dispersive SPE sample clean-up...

Escherichia coli O157:H7 is an important food-borne pathogen and has ability to contaminate food, such as water, meat products, and milk. Moreover, E. coli O157:H7 is the main toxin-producing serotype which can produce Shiga toxin type 1 and type 2 and cause intestinal disease. The strong pathogenicity and lethality of Escherichia coli O157:H7 pose a serious threat to human. This study aims to develop a rapid and visual detection assay of E. coli for rfbE, stx1, and stx2 genes by crossing primin...

An assay-based method was developed to determine the residual activity of the maltogenic amylase from Geobacillus stearothermophilus in white bread. It was found that the important step for amylase extraction from the bread matrix was the addition of 10% (w/v) maltodextrin in the extraction buffer. The endogenous amylase activity in dough was investigated, and its inactivation during bread baking was proven. Thus, all amylase activities measured after baking have an exogenous origin. The amylase...
