High Purity White Powder 94% STPP Sodium Tripolyphosphate for Food
Additive Grade with Factory Price
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
1. Food grade sodium tripolyphosphate (STPP) can improve the taste
and texture of food. Sodium tripolyphosphate can make food more
delicate and soft, and can prevent protein condensation in food,
maintaining its natural taste and texture.
2. Food grade sodium tripolyphosphate (STPP) can be used as a water
retaining agent and preservative. Sodium tripolyphosphate can
combine with metal ions such as protein, calcium, and magnesium in
food to form soluble complexes, thereby reducing the hardness of
the solution and increasing the water retention and freshness of
food.
3. Food grade sodium tripolyphosphate (STPP) can be used as a
leavening agent. During food processing, sodium tripolyphosphate
can generate gas, which increases the volume and softness of food.
For example, when making baked goods such as cakes and cookies,
adding an appropriate amount of sodium tripolyphosphate can improve
the taste and texture of the product.
4. Food grade sodium tripolyphosphate (STPP) can be used as a
coagulant. Sodium tripolyphosphate can coagulate proteins, starch,
and other components in food, thereby improving the structure and
stability of the food.
5. Food grade sodium tripolyphosphate (STPP) can serve as a metal
chelating agent and pH regulator. Sodium tripolyphosphate can
prevent the formation of scale and precipitation, regulate the pH
value of food, and improve the stability and texture of food.
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.
