New Zealand has gone into lockdown to prevent the spread of Covid‑19. As a non-essential worker, I will be working from home for now until the lockdown ends. Fortunately, much of my work is computer-based and I can successfully do many tasks from my office at home. I hope that we get on top of the virus and limit it's spread so that we can go back to living our lives safely.
SPIFAN meetings at AOAC Mid-Year Meeting—Gaithersburg, MD, USA
Due to Covid‑19 pandemic, I was unable to attend the AOAC Mid-Year Meeting in Gaithersburg, MD. Quite disappointing not to be able to catch up with friends and colleagues. However, I felt very nervous about travelling and it is a relief not to put my health at risk, or that of my family upon my return to New Zealand. The good news is being able to participate in AOAC meetings remotely.
Congratulations to my colleague and friend Dr. Harvey Indyk, who was made an Officer of the New Zealand Order of Merit in the New Year’s Honours List. A very prestigious honour and well-deserved.
Paper accepted for publication entitled "Rapid method for the determination of sorbic acid in cheese by high performance liquid chromatography" to be published in the Journal of AOAC International. The paper describes a high-throughput method for routine testing of sorbic acid. The method was subjected to single laboratory validation and was found to be accurate, precise, and fit-for-purpose.
Paper accepted for publication entitled "Rapid method for the determination of thiamine and pantothenic acid in infant formula and milk-based nutritional products by LC‑MS/MS" to be published in the Journal of AOAC International. This paper describes the successful development of a chromatographic method for routine product compliance release testing of thiamine and pantothenic acid in manufactured infant and milk-based nutritional products.
Paper accepted for publication entitled "Differential thermal isomerization: its role in the analysis of vitamin D3 in foods" to be published in the Journal of AOAC International. This paper details the challenging aspects of vitamin D analysis due to thermal equilibration between vitamin D and previtamin D forms.
I attended the 133rd AOAC Annual Meeting in Denver. The AOAC Annual Meeting offers scientific sessions, roundtables, workshops, and poster presentations to meet a variety of analytical needs and brings the attendees science-based research from the top scientists in the world to discuss technical information about changes and advances in methodology and provide access to the latest techniques and applications. I have many meetings to attend this time around as a volunteer and especially important are the SPIFAN meetings.
Paper accepted for publication entitled "Development and application of an optical biosensor immunoassay for aflatoxin M1 in bovine milk" to be published in the Food Analytical Methods. This paper describes the development of a method for measuring aflatoxin M1 in milk. Aflatoxin M1 is the hydroxylated metabolite of aflatoxin B1 and can be found in milk or milk products obtained from livestock that have ingested contaminated feed. The method facilitates routine screening for aflatoxin M1 content prior to confirmatory analysis by reference chromatographic methods.
Paper accepted for publication entitled "The analysis of vitamin B12 in milk and infant formula: a review" to be published in the International Dairy Journal. This review discusses the application of modern instrumental techniques for analysis of vitamin B12 in milk as well as a variety of sample preparations, together with their respective advantages and drawbacks.
Attended the ISO TC34/WG14 Meeting to discuss adoption of SPIFAN methods as ISO international standards. The city of Bergen is beautiful in summer. The markets are full of fish and dining out was a pleasure at some of the many seafood restaurants.
