Sodium aluminium phosphate (SALP) is a versatile food additive that functions as both a leavening agent and an emulsifying salt. It is classified under CAS number 7785-88-8 and appears in FDA regulations as GRAS (Generally Recognized As Safe) for use in baked goods, processed cheese, and other formulations. For kosher food manufacturers, confirming the certification of every processing aid is a critical step in production.
SALP is widely used in two distinct forms: the acidic form acts as a leavening agent in baking, while the basic form serves as an emulsifying salt in cheese production. Both forms require separate evaluation under kosher dietary guidelines to ensure compliance throughout the supply chain.
How SALP Meets Kosher Requirements
Sodium aluminium phosphate is a synthetic mineral salt produced from inorganic raw materials, specifically sodium, aluminium, and phosphoric acid sources. Because it contains no animal-derived components, the base ingredient is inherently pareve. Major suppliers like Innophos manufacture SALP under both FCC (Food Chemicals Codex) and kosher certification standards.
The FDA recognizes SALP under 21 CFR 182.1781 and 182.90, permitting its use as an anticaking agent, drying agent, emulsifier, humectant, leavening agent, and texturizer. Kosher certifying agencies verify that the production process, facility conditions, and all auxiliary chemicals meet dietary law requirements before granting approval.
Key Food Applications for Kosher SALP
In processed and imitation cheese manufacturing, SALP acts as an emulsifying salt that helps create a smooth, uniform melt. According to FDA standards under 21 CFR 133, it is specifically permitted in pasteurized process cheese (133.169), cheese food (133.173), and cheese spread (133.179). Suppliers describe it as a white, odorless, and tasteless ingredient suited for these applications.
As a leavening agent, the acidic form of SALP reacts with baking soda to produce carbon dioxide gas in doughs and batters. It is approved for use in self-rising flour (137.105), enriched flour (137.180), and enriched farina (137.270). Its slow-acting reaction profile gives bakers better control over rise timing compared to faster-acting acids.
Certification and Compliance Details
Leading SALP producers hold both Halal and Kosher certifications for their food-grade products. Nelson-Jameson distributes Innophos Kasal brand SALP with FCC compliance, and the product is available in standard 40-bag pallets with a minimum order quantity of one pallet. Buyers should request current kosher certificates specifying the certifying agency and pareve designation.
Food manufacturers working with SALP should verify that each lot received carries documentation matching the approved kosher certificate. Since SALP is produced in chemical processing plants that may handle multiple products, dedicated production lines or thorough cleaning protocols between runs are essential for maintaining kosher status.
