Potassium Metabisulphite (KMS Food Preservative) (E224)

Description:

Potassium Metabisulphite (KMS) is a widely used preservative and antioxidant in the food and beverage industry, recognized by its food additive code E224. It is primarily used to preserve the color, flavor, and freshness of various foods, and as a powerful antioxidant, it prevents browning and microbial growth. KMS is also used in winemaking, brewing, and other fermentation processes to inhibit undesirable bacteria and wild yeasts while allowing controlled fermentation.

Applications:

• Food Industry:
  Commonly used in dried fruits, fruit juices, jams, pickles, and canned vegetables to preserve color and freshness. It prevents oxidation and spoilage, extending product shelf life.
• Beverage Industry:
  Used in wines and beers to control the fermentation process and inhibit unwanted microbial activity. It helps maintain the desired flavor and prevents spoilage.
• Winemaking:
  As an antioxidant and antimicrobial, KMS is essential in winemaking to protect the wine from oxidation and bacterial contamination, ensuring a stable fermentation process.
• Brewing Industry:
  Helps maintain clarity and freshness in beer by preventing unwanted microbial growth and oxidation.

Key Features:

• Effective Preservative: Protects against oxidation, microbial growth, and discoloration in foods and beverages.
• Antioxidant Properties: Prevents browning in fruits, vegetables, and beverages, helping to maintain product quality.
• Controls Fermentation: Inhibits undesirable microorganisms in wines and beers, ensuring proper fermentation and preservation.
• Regulated Use: Recognized as safe (GRAS) under regulated use by food authorities, including the FDA and EFSA.
• Cost-Effective: Efficient at low concentrations, making it an economical option for food and beverage preservation.

Handling and Storage:

• Storage Conditions: Store in a cool, dry, and well-ventilated area. Keep the container tightly closed and protected from moisture and direct sunlight.
• Handling: Use protective equipment such as gloves and masks. Avoid inhalation of dust or fumes and avoid skin contact, as it can cause irritation.

Packaging:

Available in various packaging sizes, from small bags for small-scale use in food preparation to larger quantities for industrial food processing and winemaking.

Safety and Precautions:

• Sulphite Sensitivity: Potassium Metabisulphite can cause allergic reactions in individuals sensitive to sulfites, leading to symptoms like asthma or skin irritation. It should be used in regulated amounts as specified by food safety authorities.
• Usage Limits: The amount of KMS allowed in foods and beverages is regulated to ensure safety. Follow guidelines for safe use in food and beverage production.
• Environmental Concerns: Proper disposal is required to avoid environmental contamination, as it can release sulfur dioxide (SO2) gas in contact with acids or moisture.

Regulatory Information:

• Food Additive Code: E224
• Approval: Approved for use in foods and beverages by global regulatory authorities such as the FDA (USA) and EFSA (EU).
