Succinic acid is a white, odorless, crystalline dicarboxylic acid that serves as an acidity regulator and flavoring agent in the food and beverage industry. It appears naturally in many foods and is also produced commercially through chemical synthesis or fermentation processes. Its CAS number is 110-15-6.
For food manufacturers operating under kosher guidelines, succinic acid is available in FCC (Food Chemical Codex) grade with kosher certification. This ensures the ingredient meets both food safety and religious dietary requirements for use in kosher-labeled products.
Succinic Acid Specifications and Food Grade Standards
Food-grade succinic acid must meet FCC standards, which set strict purity requirements. A typical kosher FCC-grade product has an assay of 99.50% to 100.50% as C4H6O4, with moisture content at 0.3% maximum. Heavy metal limits include arsenic below 2 ppm, lead below 2 ppm, and iron below 10 ppm.
Additional specifications include ash content below 0.1%, sulfur below 150 ppm, phosphorous below 3 ppm, and chlorine below 10 ppm. Unsaturated compounds must remain below 0.1%. These tight controls ensure the product is suitable for direct food contact applications.
How Succinic Acid Functions in Food Products
Succinic acid works primarily as a buffer, neutralizing agent, and acidity regulator in food systems. It helps maintain consistent pH levels in processed foods and beverages. As a flavoring agent, it contributes a mildly tart taste that can enhance the overall flavor profile of finished products.
In beverage formulation, succinic acid adjusts acidity without the sharp bite of citric acid. It is also used as a sequestrant, binding metal ions that could otherwise cause off-flavors or discoloration. Dietary supplement manufacturers use it in the production of metoprolol succinate and other succinate-based compounds.
Kosher Certification for Succinic Acid
Kosher succinic acid is available from multiple certified suppliers. Penta Manufacturing Company offers Succinic Acid FCC with kosher certification, providing full documentation including food grade certificates, GRAS certificates, and allergen statements.
The kosher status of succinic acid depends on its production method. Chemically synthesized succinic acid from petroleum-derived maleic anhydride typically presents fewer kosher concerns. Bio-based succinic acid produced through fermentation requires verification that all fermentation inputs, including microbial cultures and growth media, are kosher-approved.
Packaging and Storage
Bulk kosher succinic acid is commonly packed in 25 kg (55 lb) net bags, with 40 bags per pallet. It should be stored in a cool, dry environment away from direct sunlight to maintain stability and prevent moisture absorption. The crystalline form remains stable under standard warehouse conditions.
When receiving shipments, verify that the kosher certificate matches the lot number on the packaging. Maintain records linking each lot to its corresponding kosher documentation for audit purposes and supply chain traceability.
