Investigation into the presence of alkaloids in single-use food-contact articles (FCA).

In this work, we have developed a method to investigate the presence of four alkaloids and their migration potential from single-use, biodegradable derived dinnerware. The seeds of palm, commonly referred to as the betel nut, are known to contain high concentrations of four alkaloids: arecoline, guvacoline, areciadine, and guvacine. Migration of these alkaloids into a food simulant was determined using a single-sided migration cell.

Analyte and matrix method extension of per- and polyfluoroalkyl substances in food and feed.

The development and expansion of analytical methods for per- and polyfluoroalkyl substances (PFAS) in food are essential for the continued monitoring of the United States (US) food supply and assessments of dietary exposure. In March 2022, the European Union Reference Laboratory for Halogenated Persistent Organic Pollutants in Feed and Food (EURL POPs) released a guidance document covering priority PFAS of interest, including analytical method parameters and limits of quantification (LOQs). As a result, the Food and Drug Administration (FDA) began method extension work to incorporate ten new additional analytes to method C-010.

Analysis of Per- and Poly(fluoroalkyl) Substances (PFASs) in Highly Consumed Seafood Products from U.S. Markets.

Seafood consumption has been identified as one of the major contributors of per- and poly(fluoroalkyl) substances (PFASs) to the human diet. To assess dietary exposure, highly consumed seafood products in the United States were selected for analysis. The analytical method previously used for processed food was extended to include four additional long-chain perflurocarboxylic acids (PFCAs), which have been reported in seafood samples.

Extraction and analysis of an organophosphate salt nucleating agent from irradiated polypropylene resin.

Although it is well-established that irradiation of produce can reduce food-borne pathogens and spoilage organisms, data on the effect of irradiation on polymer additives in food packaging materials are limited, particularly for those additives used in packaging leafy greens or in current food packaging materials. We investigated the effects of irradiating a nucleating agent, aluminium, hydroxybis[2,4,8,10-tetrakis(1,1-dimethylethyl)-6-hydroxy-12H-dibenzo [d,g][1,3,2]dioxaphosphocin 6-oxidato]- (CAS Reg. No.

Analysis of per- and poly-fluoroalkyl substances (PFAS) in processed foods from FDA's Total Diet Study.

Additional occurrence data are needed to better understand human exposure to per- and poly-fluoroalkyl substances (PFAS) from commercially available foods in the United States. The Food and Drug Administration's (FDA) Total Diet Study (TDS) collects foods that are both nationally and regionally distributed. In 2018, 172 processed foods were collected from grocery stores around Lenexa, KS, as part of the TDS national collection.

Method Development and Validation of Per- and Polyfluoroalkyl Substances in Foods from FDA's Total Diet Study Program.

Human exposure to per- and polyfluoroalkyl substances (PFAS) through the US diet has not been well-characterized. Highly consumed foods are routinely monitored through FDA's Total Diet Study program. Portions of these samples were used to develop and validate a method for PFAS in a wide variety of foods.

Investigation into the Concentrations and Sources of Nitrates and Nitrites in Milk and Plant-Based Powders.

Milk powders in the United States (US) may contain nitrates and nitrites from several potential sources. These sources include the ingestion of nitrates and nitrites by dairy cows during grazing and drinking, nitric acid used during the sanitization of dairy equipment, and the production of nitrous oxides in directly heated spray dryers. Recently, milk powders manufactured in the US have been rejected during import to other countries because nitrite concentrations were greater than 2 mg/kg (ppm).

Assessment of the Impact of Accelerated Migration Testing for Coated Food Cans Using Food Simulants.

In this study, an accelerated migration test on food can coatings into food simulants was investigated. Food simulants covering a wide range of polarity were used to conduct migration tests at 60 °C with storage times ranging from 4 h to 30 days. Epoxy-resins, acrylic-phenolic, polyester, and vinyl coatings were exposed to water, 3% acetic acid, 50% ethanol, and Miglyol 812.

Analysis of diglycolic acid in food packaging, over the counter products, direct additive carboxymethyl cellulose, and retail foods.

Carboxymethyl cellulose (i.e. CMC or cellulose gum) is used as a direct additive for foods and drugs to change texture and act as a binder.

Determination of endogenous concentrations of nitrites and nitrates in different types of cheese in the United States: method development and validation using ion chromatography.

Nitrites and nitrates can be present in dairy products from both endogenous and exogenous sources. In the European Union (EU), 150 mg kg of nitrates are allowed to be added to the cheese milk during the manufacturing process. The CODEX General Standard for Food Additives has a maximum permitted level of 50 mg kg residue in cheese, while in the United States (U.

Investigation into perfluoroalkyl substances (PFASs) in a cranberry bog: method development and sampling results.

The contamination of groundwater and surface water from previous uses of perfluoroalkyl substances (PFASs), particularly products containing the contaminants perfluorooctane sulfonate (PFOS) and perfluorooctanoate (PFOA), has become a concern for drinking water and as a potential exposure route to the food supply. In 2016, the Food and Drug Administration (FDA) was asked to investigate a bog in Massachusetts where the surface water was believed to be contaminated with PFASs. As a result, a method was developed for the analysis of PFASs in cranberries, and water and fruit from the affected bog were evaluated.

Simultaneous Analysis of 3-MCPD and 1,3-DCP in Asian Style Sauces Using QuEChERS Extraction and Gas Chromatography-Triple Quadrupole Mass Spectrometry.

Acid hydrolyzed vegetable protein (aHVP) is used for flavoring a wide variety of foods and also in the production of nonfermented soy sauce. During the production of aHVP, chloropropanols including 3-monochloropropane-1,2-diol (3-MCPD) and 1,3 dichloropropane-2-ol (1,3-DCP) can be formed through the reaction of the hydrochloric acid catalyst and residual fat and the reaction of 3-MCPD with acetic acid, respectively. 3-MCPD is a carcinogen, and 1,3-DCP has been classified as a genotoxic carcinogen.

The Food and Drug Administration Office of Women's Health: Impact of Science on Regulatory Policy: An Update.

The U.S. Food and Drug Administration Office of Women's Health (FDA OWH) has supported women's health research for ∼20 years, funding more than 300 studies on women's health issues, including research on diseases/conditions that disproportionately affect women in addition to the evaluation of sex differences in the performance of and response to medical products.

Method development and survey of Sudan I-IV in palm oil and chilli spices in the Washington, DC, area.

Sudan I, II, III and IV dyes are banned for use as food colorants in the United States and European Union because they are toxic and carcinogenic. These dyes have been illegally used as food additives in products such as chilli spices and palm oil to enhance their red colour. From 2003 to 2005, the European Union made a series of decisions requiring chilli spices and palm oil imported to the European Union to contain analytical reports declaring them free of Sudan I-IV.

An investigational report into the causes of pine mouth events in US consumers.

Between July 2008 and June 2012, the US Food and Drug Administration received 501 consumer reports of prolonged taste disturbances consistent with pine mouth syndrome. Consumers consistently reported a delayed bitter or metallic taste beginning hours to days following consumption of pine nuts that recurred with intake of any food or meal. This dysgeusia lasted in some cases up to a few weeks, but would eventually resolve without serious health consequences.

Assessments and improvements in methods for monitoring seafood safety in response to the Deepwater Horizon oil spill.

As a result of the April 2010 Deepwater Horizon oil spill, sensory testing protocols were established for reopening closed seafood harvest areas. In order to improve this method and quantitatively assess petrochemical taint, a new method using solid phase microextraction (SPME) and a 5975T transportable GC/MS was developed. This method can analyze 40 samples per instrument per day and could be an alternative to the human sensory panel.
