A Small Overview and Comparison

The protein content in food and feeds is one of the parameters that are commonly analysed within most routine control samples in a food laboratory. Generally, the two most used reference methods/technologies are the wet chemistry method after Kjeldahl and the combustion method after Dumas.

Year after year, the popularity of juice continues to rise. As consumers become more health- and environmentally-conscious, juice has risen to the forefront as a sustainable, vegan, and nutritious beverage option.

Pesto can trace its roots back to ancient times, though it really only started taking off in North America in the 1980s and 90s. Though the primary base is consistent, with pine nuts, basil, and olive oil, individual recipes vary. As canned and bottled pesto became more accessible, individual manufacturers developed their own unique flavor profiles. While these recipes are usually trade secrets, the power of GC×GC TOFMS can tease apart some of the differences.

The price of crude oil is one of the great drivers of our economy. At a minimum, the price of all goods includes costs of transporting them from manufacturer to consumer. But the price of crude oil and other oil materials can feel fickle, increasing and decreasing with supply or demand or even just market sentiment.
