Insight: Sugar formats change the questions buyers should ask about kosher requirements
Cosmo Food EU EditorialSTAR-K’s Summer 2026 educational article examines cane-sugar production and the kosher questions associated with refining. It discusses filtering aids, bone-char decolorants and anti-foaming agents, explaining why their use does not automatically disqualify pure sugar. Its guidance allows pure cane or beet sugar without certification for ordinary kosher use, while considering Passover requirements separately.
The distinctions become more specific when sugar contains other ingredients. The article explains that confectioners’ sugar commonly includes a free-flow agent, often cornstarch, and that some non-domestic producers use wheat starch. It also discusses how reworking confectioners’ sugar into another production line can introduce that added starch. These examples form part of its Passover analysis, rather than a claim that every sugar product has the same requirements.
Cosmo’s buyer view: identify whether a quotation covers pure granulated sugar, powdered sugar or a blend. Ask for the complete ingredient specification and clarify added starches, relevant processing aids, the production site and rework practices. Keep the requested customer standard separate from a broad description such as “sugar”.
For a project with kosher or Passover requirements, obtain current approval for the exact product and site through the customer’s certification process. The article is an educational reference, not a certificate for a supplier or finished SKU. It provides no evidence that any Cosmo product or manufacturer is certified, and STAR-K is not endorsing Cosmo.
