SRM 1548a - Typical DietThis Standard Reference Material (SRM) is intended primarily for use in validating analytical methods for the determination of proximate content and minor and trace constituent elements in mixed diets and food matrices. The base material used for SRM 1548a originated from food menus used for metabolic studies performed at the USDA Beltsville Human Nutrition Research Center. SRM 1548a is a blended freeze-dried homogenate of these menus. This SRM may also be used for quality
assurance when assigning values to in-house control materials. SRM 1548a Typical Diet is the renewal for SRM 1548 Total Diet. keywords: biological material , foodstuff , trace elements ,
