Food - Grade STPP Product Description

1. Product Overview

Our Food - Grade STPP (Sodium Tripolyphosphate) is a top - quality, white, granular powder. It is an essential additive in the food industry, known for its multiple functions and high - purity composition that meets the strictest food - safety standards.

2. Key Specifications

• Purity: Meets or exceeds food - grade purity requirements. Our STPP has a minimum purity level ensuring reliable performance in food applications.

• Appearance: Fine, white granules that are free - flowing, making it easy to handle and incorporate into various food products.

• Molecular Formula: Na₅P₃O₁₀

• Solubility: Highly soluble in water, which is crucial for its effective use in liquid - based food formulations as well as for dissolving in the preparation of food products.

3. Main Features

• Sequestrant Properties: STPP has excellent sequestering abilities. It can bind to metal ions such as calcium and magnesium present in food. This property helps prevent the formation of unwanted precipitates, discoloration, and off - flavors, thus maintaining the quality and appearance of food products. For example, in canned vegetables, it can prevent the hardening of vegetables due to the presence of metal ions in the water used for canning.

• pH Adjustment: It can act as a buffer to adjust and maintain the pH level in food systems. This is important for controlling the acidity or alkalinity of certain foods, which in turn affects their taste, texture, and shelf - life. In some processed meats, STPP helps maintain the right pH for optimal curing and preservation.

• Emulsification and Water - Holding Capacity: STPP improves the emulsification of fats and oils in food products. It also enhances the water - holding capacity of proteins, which is beneficial in products like meat products, where it helps retain moisture during cooking. This results in juicier and more tender meat products.

4. Applications

• Meat and Poultry Products:

• Used in marinating solutions for meat and poultry. It helps in tenderizing the meat, enhancing its water - holding capacity, and improving the texture and flavor. For example, in pre - cooked ham, STPP ensures that the ham remains moist and has a better texture during storage and reheating.

• Assists in the curing process of meats, helping to develop the characteristic color and flavor associated with cured products.

• Seafood Products:

• In frozen seafood, STPP is used to prevent freezer burn by retaining moisture. It also helps in maintaining the natural color and texture of the seafood, preventing discoloration and toughening.

• For fresh seafood, it can be used in soaking solutions to improve the quality and shelf - life by reducing drip loss during storage.

• Beverage Industry:

• In soft drinks and fruit juices, STPP is used as a sequestrant to prevent the cloudiness caused by metal ions. It also helps in maintaining the stability of the flavor and color of the beverages over time.

• Can be used in the preparation of bottled water to control the mineral content and prevent the formation of scale in the bottles.

• Dairy Products:

• In processed cheese, STPP is used to improve the melting properties and texture. It helps in creating a smooth and creamy consistency by preventing the separation of fats and proteins.

• Can be added to milk - based products to enhance their stability and prevent the formation of curds.

5. Packaging and Storage

• Packaging: Our Food - Grade STPP is available in various packaging sizes to meet your needs. We offer both small - scale packaging for food processors with limited production volumes and large - scale bulk packaging for industrial - scale food manufacturers. All packaging is designed to ensure the product remains protected from moisture, dust, and contaminants.

• Storage: Store in a cool, dry place away from direct sunlight. Keep the containers tightly closed when not in use to prevent moisture absorption, which could affect the product's performance. Proper storage conditions will help maintain the quality of the STPP for an extended period.

6. Safety and Regulatory Compliance

Our Food - Grade STPP complies with all relevant international food - safety regulations, including those set by the FDA (Food and Drug Administration) and EU food - safety standards. It is approved for use in a wide range of food products, ensuring that you can use it with confidence in your food manufacturing processes.

When handling STPP, although it is a food - grade product, it is advisable to follow standard good - manufacturing - practice (GMP) guidelines. Avoid inhalation of dust and direct contact with eyes and skin. In case of accidental contact, rinse thoroughly with water.
