TORONTO, October 2, 2018 – Join Marco Snikkers, Manager of Business Development and Strategy for Food and Agriculture at Ocean Optics, for a live webinar upcoming on Friday, October 19, 2018 at 11am EDT (4pm BST/UK).
The Promises and Complexities of the “Tricorder”
Today’s portable spectroscopy tools have evolved from lab instruments to field-based devices that can be easily configured for food safety testing and analysis, providing users with instant feedback and reliable results. When the appropriate approach is taken during development, custom systems for non-destructive, high-speed contaminant screening and quality sorting can be produced affordably and reproducibly. In this webinar, we will take a journey from assessing the feasibility of the application to developing a robust analytical tool for a specific solution.
Maintaining food safety and integrity across vast and occasionally vulnerable systems is an ongoing challenge complicated by factors including pressure to increase food production to meet population growth; the threat posed by harmful microorganisms and pesticides; and the potentially dangerous consequences of food fraud.
But there’s good news: issues regarding food safety and integrity have inspired a new generation of testing and screening methods with optical sensing technologies like portable spectroscopy at their core. As this webinar explores, spectroscopy tools — and the software algorithms that analyze the spectral data those tools produce — are helping to provide faster, simpler to use and more easily deployed screening and analysis tools throughout the food chain.
Many food safety testing and analysis parameters have been established in lab environments using analytical chemistry and microbiological tests. However, these tests often take considerable time and expertise to execute, and cannot be replicated easily in the field.
Those disadvantages are especially relevant in cases where adulterated food has exposed the public to the risk of injury and even death. Over the past decade, the most egregious cases of food contamination – highly toxic melamine in milk powder in China that sickened thousands of babies, and industrial oil contamination of animal feed used in the European pork market that forced a major recall – have helped spur the development of faster and more easily deployed adulterant detection technologies.
Optical sensing techniques such as portable UV, visible and NIR spectroscopy offer rapid, low-cost capabilities that complement traditional lab testing. The real-time data these spectroscopic tools capture can be combined with powerful algorithms to extract valuable insight on food samples and result in earlier assessment and identification of food contaminants.
Absorbance, reflectance and Raman spectroscopy systems from companies including Ocean Optics have proven useful for food safety testing and analysis of foods. For example, reflectance and through-sample transmission techniques in visible spectroscopy and NIR spectroscopy work well for fruit and dairy product testing; fluorescence has been used to detect mycotoxins in grains.
Also, surface enhanced Raman spectroscopy (SERS) – a highly sensitive technique useful for trace level detection of contaminants – has been applied to the detection of banned pesticides and fungicides on produce, as well as antibiotics and fungicides used in illegal fish farming. Ocean Optics offers highly selective SERS substrates with the measurement sensitivity and cost per use to make field testing feasible and affordable.
Choosing a Spectroscopy System for Food Safety Testing
Ocean Optics offers a full menu of spectrometers, multispectral imaging products, chemical sensors and accessories for food safety testing and analysis. As we’ll discuss, these tools can easily be configured for specific screening solutions, with users choosing from several options:
- Hardware options — point or imaging spectroscopy; UV, visible or NIR wavelengths
- Sampling interface — point-and-shoot, at-line or in-line
- Algorithm development — targeted or non-targeted food analysis; empirical analysis versus machine learning
Originally conceived as a research tool, portable spectroscopy has evolved beyond one-off, single-lab use to being at the centre of fully customized solutions to detect contaminants or monitor quality. Ocean Optics’ optical sensing solutions and applied spectroscopy knowledge are uniquely placed to deliver custom solutions from prototype to mass production. This is especially attractive for food producers and government regulators that until now may not have had access to simple and economical yet still robust food screening options.
