DESCRIPTION
E325 Sodium Lactate is the sodium salt of lactic acid and is commonly produced by neutralizing lactic acid with sodium hydroxide, resulting in a water-soluble lactate salt.
E325 Sodium Lactate functions as a humectant by binding water, and this water binding helps improve juiciness, reduce purge, and maintain softness in many foods.
E325 Sodium Lactate can help support microbial stability strategies by lowering water activity and contributing to pH control, but E325 Sodium Lactate is not a standalone preservative and must be used with proper processing and safety controls.
E325 Sodium Lactate provides mild buffering behavior, and this buffering can help stabilize pH and reduce harsh acidity in some formulations.
E325 Sodium Lactate can influence flavor and salt perception, and sodium lactate typically provides a mild salty taste with low harshness compared with some other salts.
E325 Sodium Lactate should be used according to applicable food additive regulations and good manufacturing practices for the target market.
E325 Sodium Lactate is typically supplied as an aqueous solution, and concentration affects viscosity, handling, and dosing strategy.
E325 Sodium Lactate should be stored in tightly closed containers to prevent contamination and concentration changes, and tanks should be kept clean for food-grade handling.

FIRST AID
Inhalation:
Move to fresh air if mists are inhaled.
Seek medical attention if respiratory irritation persists.
Avoid breathing aerosols during spraying and heated handling.
Skin Contact:

Remove contaminated clothing and wash before reuse.
Seek medical advice if irritation develops or persists.
Eye Contact:
Rinse cautiously with water for several minutes.
Remove contact lenses if present and easy to do, then continue rinsing.
Seek medical attention if irritation persists.
Ingestion:
Rinse mouth with water.
Seek medical attention if discomfort occurs or if a large amount is swallowed.
Never give anything by mouth to an unconscious person.
Note to Physicians:
Treat symptomatically.
No specific antidote is required.
Provide supportive care as needed.
HANDLING AND STORAGE
Handling:
Use appropriate PPE including gloves and safety glasses for bulk handling.
Avoid splashing into eyes and maintain good hygiene in liquid handling lines.
Wash hands after handling and before eating, drinking, or smoking.
Ventilation:
Use general ventilation for normal handling.
Use local exhaust if spraying or heated handling generates mists.
Avoid aerosol formation in enclosed spaces without adequate airflow.
Storage:
Store in tightly closed containers or tanks in a cool, clean area.
Protect from contamination by maintaining sanitary transfer lines and closed handling.
Avoid prolonged exposure to high heat that can change color and odor over time.
Spill and Leak Procedures:
Contain and clean spills promptly because liquids can create slip hazards.
Wash down residue with water and remove slick films from floors.
Dispose of waste according to local regulations and facility procedures.
Handling Precautions:
Optimize dosage because E325 Sodium Lactate affects water retention, flavor, and pH, and excessive levels can create salty or bitter notes.
Use E325 Sodium Lactate as part of a validated food safety and preservation strategy rather than relying on E325 Sodium Lactate alone.
Rotate stock using FIFO practices and maintain sanitary handling to ensure consistent quality and avoid contamination.
