Food Grade Potassium Sulfate

Basic Product Parameters

This product is inorganic potassium sulfate with a fixed molecular formula of K2SO4 and a molecular weight of 174.26. The registered CAS number is 7778-80-5, complying with international chemical product identification standards for cross-border procurement, customs declaration and product filing.

Physical & Solubility Properties

The product presents colorless or white hard crystalline solid or crystalline powder form with a bitter and salty taste. It has a relative density of 2.662 under standard temperature and pressure conditions. In terms of solubility, 1 gram of potassium sulfate dissolves in approximately 8.5 milliliters of water, and shows no solubility in ethanol and acetone. The pH value of its 5% aqueous solution ranges from 5.5 to 8.5, with stable acid-base properties for conventional application scenarios.

Core Applications

Qualified potassium sulfate is primarily applied in food processing scenarios as a conventional seasoning ingredient and a standard salt substitute material. It adapts to formula adjustment requirements for low-salt food production and meets basic material application standards for food manufacturing enterprises.

Standard Packaging Specification

We adopt double-layer sealed packaging for bulk supply. The inner layer is made of food-grade polyethylene bag for moisture isolation and pollution prevention, while the outer layer is compound plastic woven bag for mechanical damage resistance. Each finished package has a fixed net weight of 25kg, supporting unified bulk procurement, container loading and inventory management for industrial buyers.

Storage & Transportation Requirements

The product requires storage in dry and well-ventilated warehouse environments to avoid damp deterioration. During land and sea transportation, it shall be kept away from high-temperature sources and humid environments. Manual and mechanical unloading operations need to be handled carefully to prevent package breakage and material leakage. Separate storage and transportation from all toxic chemical substances is mandatory to ensure product purity and safety compliance.
