USP Proposes Identity Standards for Pomegranate Juice; Monograph for Spirulina

July 8, 2013

The proposals are intended to support authentication of these ingredients.

Among the many additions scheduled for the ninth edition of the Food Chemicals Codex, the U.S. Pharmacopeial Convention (USP) is proposing new identity standards for pomegranate juice, a monograph for spirulina, and a monograph for a synthetic black colorant called Brilliant Black PN.

Pomegranate juice doesn’t currently have a monograph-nor is one scheduled-but informal identity standards would help manufacturers verify authenticity (or spot adulteration) of pomegranate juice products. The standards would include a description of the ingredient, multiple identification tests, and tests for identifying substances that should not be present, including sorbitol and tartaric acid.

Spirulina manufacturers can benefit from a monograph, as it would indicate the ways in which to test against contamination of microcystins, toxic compounds found in other algal strain that may appear similar to spirulina.

Brilliant Black PN has found a place as black coloring in many conventional products, including jams, syrups, and candies. While FDA has not approved the color, Brilliant Black PN is allowed in several other countries. New reference standards would help manufacturers target impurities in their product.

Interested parties have 90 days, until September 30, 2013, to comment on the proposals. Free registration is required.
