1. Product Introduction
High purity white powder 94% sodium tripolyphosphate, commonly
abbreviated as STPP, is an inorganic compound that plays a vital
role in various industries and applications. It belongs to the
family of polyphosphates and is composed of sodium cations (Na+)
and tripolyphosphate anions (PO₃³⁻). This versatile substance is
widely used fordyeing acid, detergents, waste water treatment
softner, food preservation, and various industrial processes. We
are Chinese supplier for both industrial grade stpp and food grade
sodium tripolyphosphate.

3. Food Grade Sodium Tripolyphosphate Application
3.1. Meat and dairy products: Sodium tripolyphosphate is commonly
used in meat processing to tenderize meat, improve its tenderness
and elasticity, and enhance its taste. In dairy products, it can
enhance the stability and extend the shelf life of dairy products.
3.2. Canned food and fruit juice drinks: Sodium tripolyphosphate
used in canned food can lock in moisture, extend shelf life, and
make food taste more delicate. In fruit juice drinks, it can
increase the stability of foam and extend the shelf life.
3.3. Pastry and bread: During the production process of pastry and
bread, sodium tripolyphosphate can help maintain shape, prevent
softening, and enhance their taste and aroma.
3.4. Deep-fried dough sticks and instant noodles: in the production
of deep-fried dough sticks, sodium tripolyphosphate can make
deep-fried dough sticks more crisp and delicious; In instant
noodles, it improves the elasticity and cooking resistance of the
noodles, making them easier to cook and consume.
3.5. Ice cream: Sodium tripolyphosphate can increase the hardness
and stability of ice cream, making it less likely to melt and
improving its taste
4. The advantages of food grade sodium tripolyphosphate
1. Safe and reliable
Food grade sodium tripolyphosphate has undergone strict food safety
testing and certification, meets national food safety standards,
and can be safely used in food processing. At the same time, it can
effectively reduce the heavy metal content in food and improve food
safety.
2. Significant effect
Food grade sodium tripolyphosphate has significant effects in
improving food quality, taste, and structure. It can effectively
improve the water retention of food, prevent food cracking, improve
the organizational structure of food, and make food more delicious
and delicious.
3. Wide applicability
Food grade sodium tripolyphosphate is suitable for the processing
and storage of various foods, such as meat, fish, beans, baked
goods, etc. It can be used alone or in combination with other
additives to meet the needs of different food processing.
5. Precautions
5.1. Moderate use
When using food grade sodium tripolyphosphate, it should be used in
moderation according to actual needs to avoid excessive addition
that may lead to a decrease in food taste and quality. At the same
time, attention should also be paid to the combination of other
additives to avoid chemical reactions or adverse taste.
5.2. Storage conditions
Food grade sodium tripolyphosphate should be stored in a dry, cool,
and ventilated place, avoiding direct sunlight and high
temperatures. At the same time, attention should also be paid to
the shelf life of the product, and the packaging should be checked
for integrity and no damage before use.
