Phosphoric acid, also denoted as H₃PO₄, serves as a versatile and extensively employed acidulant within the food industry. Phosphates, on the other hand, represent salts or esters derived from phosphoric acid. When Phosphoric Acid reacts with a base (like sodium, potassium, or calcium), it forms phosphate salts.
In foods, phosphates are used for a variety of purposes including as leavening agents in baking, emulsifiers in processed cheese, and stabilizers in many processed foods. Common food-grade phosphates include disodium phosphate, trisodium phosphate, and tetrasodium pyrophosphate.
Our main product is phosphate powder, it can serve as a buffering and chelating agent. NIRAN Biochemical carefully selects quality raw materials for you. We rigorously manage production costs and product quality to offer you highly competitive prices within the food ingredients industry.
Within the food sector, phosphoric acid is predominantly utilized in its fundamental state to serve as an acidity regulator and flavor enhancer. It provides a sour and tangy taste and helps control the pH level of the food product. There are different grades and types of phosphoric acid that can be used depending on the specific application and purity requirements.
Food Grade Phosphoric Acid
This is a high-purity form of Phosphoric Acid specifically processed for food applications. It's used as an acidulant in beverages, particularly in cola-type soft drinks, to give a tangy flavor and to aid in the carbonation process.
Technical Grade Phosphoric Acid
While not used directly in food, this grade can be involved in the manufacture of food-grade phosphates, which are used as emulsifiers, stabilizers, and leavening agents in various food products.
Orthophosphoric Acid
This is another name for the pure, concentrated form of Phosphoric Acid. This form is widely employed in the food sector, especially in soft drinks, making it the most prevalent choice in the industry.
APPLICATIONS OF PHOSPHORIC ACID
Phosphoric acid is highly valued in the food industry for its versatility and efficacy as an additive. While it's prized for its ability to impart a sour flavor and act as a preservative, its use is balanced with considerations for health and nutrition, particularly in relation to dietary phosphate intake.
Beverage Industry
Soft Drinks: Phosphoric acid is commonly used in cola and other carbonated beverages for its sharp, tangy taste. It helps balance the sweetness of the drink and adds a distinct acidity that is characteristic of these beverages.
Sports Drinks: Sometimes used to adjust the pH level and add tartness, enhancing the flavor profile of sports and energy drinks.
Processed Foods
Leavening Agent: In the bakery industry, Phosphoric Acid can react with baking soda to produce carbon dioxide, helping baked goods rise.
Flavor Enhancer: It can enhance the tanginess or sourness in various processed food products.
Phosphates
Phosphates are salts formed from the combination of phosphoric acid with one or more metals, such as sodium, potassium, or calcium. Its applications are: as preservatives and acidity regulators; improving food texture and stability; as chelating agents; or as leavening agents.
Phosphorus improves energy and protein metabolism, reproduction, functioning of the nervous and immune systems, and increases animals' reproductive abilities. Calcium-enriched feed contributes to the formation of firm bone tissue and skeleton. Monocalcium Phosphate micro-granular is used in all animal feeds. Due to its high digestibility coefficient, it is extremely well suited in situations where phosphorus excretion in manure needs to be closely controlled. As a granular product, it is easily incorporated into mineral feeds. It is also well suited for use in feed blocks.
Sodium Aluminium Phosphate Food Grade Sodium Aluminium Phosphate also known as SALP. Sodium Aluminium Phosphate is a chemical used in food processing. It is synthetically produced from aluminium, Phosphoric Acid and sodium hydroxide. As a food additive it has the E number E541.
STPP Food Grade Sodium Tripolyphosphate (STPP) is one of the popular food additives and ingredients in most countries, As a professional Sodium Tripolyphosphate (STPP) supplier and manufacturer, We have been supplying and exporting Sodium Tripolyphosphate (STPP) from China for almost 20 years, please be assured to buy Sodium Tripolyphosphate (STPP) at Niranbio.

Dairy Products
Cheese Making: Phosphoric Acid may be used to set the protein in some cheese-making processes, helping in curd formation.
Preservatives
Its capacity to reduce the pH of food items renders it a potent preservative, thwarting the proliferation of microbes and fungi, and consequently prolonging the shelf life of diverse food products.
Nutrition & Dietary Supplements
Phosphoric Acid is sometimes used in the production of nutritional supplements, especially those requiring an acidic component.
Culinary Uses
In small quantities, it can be used to acidulate foods and sauces, adding a tangy flavor without overwhelming the dish.
FAQs
What is phosphoric acid and why is it used in food?
Phosphoric Acid (H₃PO₄) is a colorless, odorless phosphorus-containing inorganic acid. It finds predominant use in the food industry as both an acidity regulator and flavor enhancer, notably in cola beverages, prized for its zesty flavor profile.
Is phosphoric acid safe to consume in food and drinks?
Yes, Phosphoric Acid is considered safe for consumption in the amounts typically used in food and beverages, as approved by food safety authorities like the FDA and EFSA.
What are the common food applications of phosphoric acid?
It is most commonly used in soft drinks and sports drinks to provide a tangy flavor and to adjust the pH level. Additionally, it sees application in certain processed food items as a means of preservation.
Can phosphoric acid affect dental health?
Excessive consumption of beverages containing Phosphoric Acid, such as cola drinks, can contribute to dental erosion due to its acidic nature. It is advised to consume these beverages in moderation.
Does phosphoric acid have any nutritional value?
Phosphoric acid itself does not provide nutritional value, but phosphorus, the element in Phosphoric Acid, is an essential nutrient important for bone health.
How is phosphoric acid listed on food labels?
It is usually listed as 'Phosphoric Acid' or 'E338' in the list of ingredients on food labels.
Can phosphoric acid cause any health issues?
Ingested in normal amounts as commonly found in food and beverages, it is generally regarded as safe. However, high intake, particularly from soft drinks, has been linked in some studies to lower bone density and chronic kidney disease.
Are there any alternatives to phosphoric acid in food?
Citric acid is a common alternative, especially for adding tartness to beverages and foods, though the flavor profile is slightly different.
Is phosphoric acid used in organic or natural foods?
It is less common in organic foods, as organic standards usually favor naturally occurring substances like citric acid.
How does phosphoric acid interact with other ingredients in food?
It can interact with other ingredients to adjust pH and flavor. In beverages, it works with sweeteners to balance sweetness and tartness.
