Unlike the detailed list of nutritional requirements for human food, pet food in North America must only report on four main values in their Guaranteed Analysis on the label: protein, fat, fiber, and moisture. Additional nutrients must be included if they are called out specifically on the label, but manufacturers can also voluntarily add more nutrients to provide consumers with more information or further demonstrate the nutritional value of their products. One voluntary "nutrient" that shows up with surprising frequency in these lists is actually "Ash". But ash in the analysis doesn't actually mean ash is in the food. Rather, it explains the process by which mineral content is determined.

While plant-based proteins have been part of humanity's diet for centuries, it wasn't until the advent of the original textured vegetable protein (TVP) in the 1960s that it started becoming a viable replacement for animal-based protein sources in more mainstream diets. The first commercially available plant-based proteins would not be mistaken for animal-based protein sources and were largely of interest only to vegans, vegetarians, and pescatarians. 

The world of GC-MS applications is constantly expanding, growing into novel applications and improving classical uses. To celebrate the advancements of this powerful technology, LECO and The Analytical Scientist created an eBook that takes a look at some of the emerging uses of GC-MS. From measuring volcanic emissions to predict eruptions to developing the ultimate untargeted technique with GCxGC-MS, these articles explore a variety of topics.

Analysing animal feed samples for moisture and ash content can be a tedious and time-consuming task for labs and companies in the food and feed industry. However, with LECO's TGA801, this process can be streamlined and automated to save time and reduce manual labor.
