Macronutrients, Micronutrients, and Additives

The chemical composition of a food or beverage affects its nutritional value, sensory properties, and functionality. FSNS provides chemistry testing services for a full range of macronutrients, micronutrients, and additives that are present in foods and beverages. Our results can be used to help verify that you are meeting product specifications, determine a product’s shelf-life, or track daily process control and quality parameters.

We can also help you identify the presence of components such as tartrazine 102, yellow 2G107, benzoates 210, nitrates 252, aspartame 951, and monosodium glutamate (MSG) 621 so that your products can be labeled appropriately.

FSNS has a long history in chemistry testing for meat, poultry, and seafood. Our laboratories are accredited by USDA in fat, moisture, protein, and salt testing. Here are some of the services we provide:
