CERTIFICATION OF NUTRIENTS IN STANDARD-REFERENCE-MATERIAL-1846 - INFANT FORMULA

In 1996, the National Institute of Standards and Technology (NIST) rel eased Standard Reference Material 1846 (Infant Formula), which can be used as a control material for assigning values to in-house control ma terials and for validating analytical methods for measurement of proxi mates, vitamins, and minerals in infant formula and similar matrixes. The SRM was manufactured by preparing a spray-dried formula base conta ining fat, protein, carbohydrates, and minerals and then combining tha t formula base with a dry-blend vitamin premix that supplied the vitam ins. The Certificate of Analysis for SRM 1846 provides assigned values for concentrations of proximates (fat, protein, etc.), vitamins, and minerals for which product labeling is required by the Infant Formula Act of 1980 and by the Nutrition Labeling and Education Act of 1990. T hese assigned values were based on agreement of measurements by NIST a nd/or collaborating laboratories. Certified values are provided for vi tamins A (trans), E, C, B-2, and B-6 and niacin. Noncertified values a re provided for solids, ash, fat, nitrogen, protein, carbohydrate, cal ories, vitamin D, delta-tocopherol, gamma-tocopherol, Vitamin B-1, vit amin B-12, folic acid, pantothenic acid, biotin, choline, inositol, ca lcium, phosphorus, magnesium, iron, zinc, copper, sodium, potassium, a nd chloride. Information values are provided for iodine, manganese, se lenium, and vitamin K.
