NIST chemist Carolyn Burdette is surprised by the viral social media response to a photo of peanut butter SRM 2387, a product NIST sells among other “foods” like spinach and low-calorie cranberry juice cocktail. NIST develops standard reference materials (SRMs) to help food manufacturers calibrate their tests and equipment for accurate nutritional labeling. Buying an SRM from NIST means purchasing the scientific expertise behind the measurements. The unique challenges of food and beverage SRMs sometimes make NIST staff jealous, like the researcher who wanted to taste the baking chocolate SRM. Despite not getting to taste test, NIST ensures you get what you expect from the foods you buy.
