Quantitation of Patulin in Apple Juice and Apple Products using a Compact Mass Spectrometer

Patulin is a mycotoxin that is a common contaminant in food and animal feed, especially in apple products. The potential health risk of patulin to humans led to the establishment of action levels in foodstuffs.

The EU, WHO and US FDA defined maximum levels of patulin in fruit juices. The EU also has specific regulations for solid apple products and foods intended for infants and young children such as apple compote.

In this poster, a simple UHPLC/CMS method using the Advion AVANT UHPLC and expression Compact Mass Spectrometer (CMS) system is introduced for the analysis of patulin in apple juice and apple compotes.

This poster was presented at the ASMS 2020 Reboot.

Processing White or Yellow Dry Beans (Phaseolus vulgaris L.) into a Heat Treated Flour Enhances the Iron Bioavailability of Bean-Based Pastas

USDA-ARS, Cornell University, Michigan State University

Abstract

Processing techniques can disrupt the cotyledon cell walls of raw beans, allowing digestive enzymes greater access to intercellular stores of micronutrients such as iron during digestion. This study evaluated the iron bioavailability of seven bean varieties with different seed coat colors (white, yellow, cranberry, red, black) either boiled or processed into spaghetti pastas formulated from heat treated bean flour as the major ingredient (90% bean flour). Iron bioavailability was significantly (p ≤ 0.05) higher in spaghetti made from white or yellow bean varieties Snowdon, Alpena, Samurai and Canario when compared to boiled beans. Although cotyledon cells were broken and the phytate to iron molar ratios were significantly lower, the iron bioavailability of the cranberry (Etna), red kidney (Red Hawk) and black (Zenith) bean varieties did not improve after processing into spaghetti. Iron bioavailability of bean-based pastas was associated with procyanidin and cinnamtannin compounds that have a negative impact on the absorption of iron.

Analysis was performed by LC/MS using the Advion Interchim Scientific expression® Compact Mass Spectrometer (CMS).

Rapid authentication of agarwood by using liquid extraction surface analysis mass spectrometry (LESA‐MS)

Shanghai University of Traditional Chinese Medicine

Objective

To establish a simple, rapid and non‐destructive technique for identifying the authenticity of agarwood.

Methods

Liquid extraction surface analysis mass spectrometry (LESA‐MS) was firstly proposed to identify the authenticity of 62 agarwood samples without sample preparation. In addition, multivariate statistical models and thin‐layer chromatography (TLC) method were used to analyse and verify the results of LESA‐MS.

Conclusion

The proposed LESA‐MS method was successfully applied in the direct qualitative analysis of agarwood from different sources. This study indicated great feasibility and practicality of LESA‐MS in the rapid identification of agarwood, and provided a non‐destructive and meaningful preliminary screening tool for the agarwood industry.

Identification and quantification of cannabinol as a biomarker for local hemp retting in an ancient sedimentary record by HPTLC-ESI-MS

Martin-Luther-University Halle-Wittenberg, Free University of Berlin

Abstract

Cannabis products have been used in various fields of everyday life for many centuries, and applications in folk medicine and textile production have been well-known for many centuries. For traditional textile production, hemp fibers were extracted from the stems by water retting in stagnant or slow-moving waters.

During this procedure, parts of the plant material‚ among them phytocannabinoids‚ are released into the water. Cannabinol (CBN) is an important degradation product of the predominant phytocannabinoids found in Cannabis species. Thus, it is an excellent indicator for present as well as ancient hemp water retting.

In this study, we developed and validated a simple and fast method for the determination of CBN in sediment samples using high-performance thin-layer chromatography (HPTLC) combined with electrospray ionization mass spectrometry (ESI-MS), thereby testing different extraction and cleanup procedures‚ as well as various sorbents and solvents for planar chromatography.

This method shows a satisfactory overall analytical performance with an average recovery rate of 73%. Our protocol enabled qualitative and quantitative analyses of CBN in samples of a bottom sediment core‚ having been obtained from a small lake in Northern India, where intense local retting of hemp was suggested in the past. The findings correlate with existing records of Cannabis-type pollen. Thus, the method we propose is a helpful tool to track ancient hemp retting activities.

The Advion TLC/CMS system with the expression® Compact Mass Spectrometer (CMS) and Plate Express® TLC Plate Reader was utilized for the elution of compounds from the HPTLC plates.

Rapid and Direct Screening for Vitamin E Acetate in E-Cigarette Juices by ASAP®/CMS

The recent outbreak of severe lung injury is allegedly tied to the presence of Vitamin E Acetate (VEA) in vaping-related products after VEA was found in lung fluid samples of patients with vaping-related lung illness (EVALI). Calling for regulatory control, Washington, Colorado and Ohio have already banned the use of VEA in e-juices at the state level.

The Advion Interchim Scientific expression® Compact Mass Spectrometer (CMS) with the Atmospheric Solids Analysis Probe (ASAP®) provides a highly sensitive screening method for the presence of VEA.

Soluble Extracts from Chia Seed (Salvia hispanica L.) Affect Brush Border Membrane Functionality, Morphology and Intestinal Bacterial Populations In Vivo (Gallus gallus)

USDA Cornell University, Federal University of Viçosa

Abstract

This study assessed and compared the effects of the intra-amniotic administration of various concentrations of soluble extracts from chia seed (Salvia hispanica L.) on the Fe and Zn status, brush border membrane functionality, intestinal morphology, and intestinal bacterial populations, in vivo. The hypothesis was that chia seed soluble extracts will affect the intestinal morphology, functionality and intestinal bacterial populations…This study demonstrated that the intra-amniotic administration of chia seed soluble extracts increased (p < 0.05) the villus surface area, villus length, villus width and the number of goblet cells. Further, we observed an increase (p < 0.05) in zinc transporter 1 (ZnT1) and duodenal cytochrome b (Dcytb) proteins gene expression. Our results suggest that the dietary consumption of chia seeds may improve intestinal health and functionality and may indirectly improve iron and zinc intestinal absorption.
