All food products should be of trustworthy quality and purity, not just for consumer safety but also to ensure product authenticity and the accuracy of product labels. This is especially important for olive oils, of which there are many different types based on quality (e.g. refined, extra virgin, etc.). In some circumstances, high quality oils can be adulterated with other lower quality olive oils or oils from a different source, like canola or soybean.
Thermochromic materials are substances which reversibly change color with temperature and are commonly used in a variety of products like textiles and smart windows, among other materials.
Efficient and reliable sample preparation is essential for food manufacturers and contract laboratories tasked with delivering accurate, regulatory-compliant analytical data. From elemental testing to nutritional profiling, laboratories must manage increasingly complex matrices while maintaining fast turnaround times and data integrity. This paper explores how microwave sample preparation technologies—including digestion, extraction, and hydrolysis—support high-throughput food and feed analysis. It will also address the “total workflow” approach that ultimately helps labs reduce processing time, improve data quality, and enhance operational efficiency across a wide range of applications. Light Labs, a modern analytical testing facility committed to food safety and lab efficiency, is also featured for how they leverage single reaction chamber (SRC) microwave technology to streamline trace metals analysis.
Pt-Co, Hazen, and APHA color are three different terms referring to the same color analysis procedure often used to assess the yellowness of water samples. In this analysis a mixture of cobalt chloride and potassium hexachloroplatinate(IV) is prepared and subsequently diluted by varying amounts to form an array of yellow to almost colorless standards, as described in ASTM D1209 and ISO 6271:2015.
The human eye is able to collect the light reflected off a surface, leading to the perception of color. Since the color range we can see covers the aptly named visible range of the electromagnetic spectrum (400 – 700 nm), UV-Visible spectrophotometers are often used for color analysis.
