Ammonium Chloride is an important and versatile chemical raw material widely used in sectors such as agriculture, pharmaceuticals, industry, and food processing.
Food-grade ammonium chloride in food (E510) serves as a food additive and is commonly used in baking, dough, yeast fermentation, and flavoring.
This article breaks down the applications of ammonium chloride in the food industry, the reasons for its applications, and the precautions for its use in the food industry.
What is Ammonium Chloride?
Ammonium chloride (CAS: 12125-02-9) is an inorganic compound with the chemical formula NH₄Cl. At room temperature, it is a white crystalline powder, readily soluble in water, and hygroscopic.
It is important to note that ammonium chloride is classified into pharmaceutical grade, food grade, and industrial grade. Food-grade ammonium chloride differs strictly from industrial-grade in purity and production standards, and must comply with the food safety regulations of various countries.

Reasons for the Application of Ammonium Chloride in the Food Industry
Why is ammonium chloride used in the food industry? This is mainly based on two core factors: functional necessity and safety verification.
From a functional perspective, ammonium chloride can achieve technical effects that are difficult to replace with other additives, such as regulating fermentation speed in baked goods and balancing flavor profiles in seasonings.
Regarding safety, the Joint FAO/WHO Expert Committee on Food Additives (JECFA) has established an acceptable daily intake (ADI) for ammonium chloride, and its reasonable use will not harm human health.
Regulatory agencies worldwide generally recognize its eligibility for food applications:
The US FDA classifies it as a "Generally Recognized As Safe" (GRAS) substance, the EU EFSA approved its use as a food additive through risk assessment (code E510), and China's GB 2760-2024 also allows limited use of ammonium chloride in specific food categories.
These regulatory endorsements provide compliance guarantees for the application of ammonium chloride in the food industry.
The Role of Ammonium Chloride in the Food Industry
Synergistic Ingredient with Leavening Agents
In baked goods such as biscuits and pastries, ammonium chloride is often used in combination with leavening agents such as sodium bicarbonate. Through acid-base neutralization reactions, it releases carbon dioxide gas, creating a loose and porous structure in the product.
Compared to single leavening agents, composite systems containing ammonium chloride can more precisely control the gas production rate, avoiding quality problems such as "collapse" or "void."
A baking technology study showed that biscuit products with 0.15%-0.3% ammonium chloride have a 12%-18% higher rise rate than traditional formulas and a crispier texture.
Yeast Nutrient
Ammonium chloride is an essential nitrogen source for yeast growth, significantly enhancing yeast activity.
In bread making, adding an appropriate amount of ammonium chloride (usually 0.05%-0.1%) can accelerate dough fermentation, shorten proofing time by approximately 20%-30%, while increasing bread volume and improving internal texture.
This application is particularly important in industrial baking production, directly impacting production efficiency and product standardization.
Flavor Regulator
In the production of fermented condiments such as soy sauce and sauces, ammonium chloride can regulate the pH of the fermentation environment, promoting the activity of proteases and amylases, thereby increasing the production of flavor compounds.
Studies have shown that adding 0.08% ammonium chloride in the later stages of soy sauce fermentation can increase glutamate content by about 15%, significantly enhancing the product's umami flavor.
Furthermore, its slightly salty properties can partially replace table salt in low-sodium foods, reducing sodium intake. In the Nordic region, licorice is combined with ammonium chloride to create "salty licorice" (or salmiakki), a national delicacy popular in countries such as Finland, the Netherlands, and Sweden. In this candy, ammonium chloride not only serves as a substitute for sodium chloride but also imparts astringent, sour, and even bitter notes.
Precautions for the Use of Ammonium Chloride in the Food Industry
Strict Control of Usage
According to the Chinese standard GB 2760-2024, the usage limits for ammonium chloride vary significantly across different foods: the maximum usage is 0.5g/kg in baked goods, 0.2g/kg in condiments, and is prohibited in infant formula.
Enterprises must strictly adhere to the limits for each product category, establishing accurate ingredient weighing and recording systems to avoid safety risks associated with excessive use.
Labeling Standards
Foods using ammonium chloride must clearly list its name in the ingredient list. EU regulations also require the labeling of "contains ammonium chloride" and other relevant information.
This is both to meet consumers' right to know and a necessary measure to address the special health needs of certain groups (such as those with renal insufficiency).
Production Process Control
The production, storage, and use of food-grade ammonium chloride must adhere to strict hygiene management regulations to prevent cross-contamination with industrial-grade products.
Manufacturers should establish a comprehensive supplier audit system to ensure raw materials meet food-grade standards, such as the Chinese Pharmacopoeia's requirement for food-grade ammonium chloride purity ≥99.5% and heavy metal content (as Pb) ≤0.0005%.
Alternative Solution Evaluation
Where possible, the possibility of substituting ammonium chloride should be evaluated.
For example, in some baking recipes, ammonium sulfate or ammonium phosphate can be used instead of ammonium chloride, but the changes in product texture and flavor need to be re-verified.
Substitution decisions must comprehensively consider technical feasibility, cost factors, and regulatory requirements.
Selection of High-Quality Ammonium Chloride Suppliers
Choosing a reliable supplier is crucial to ensuring the quality of food-grade ammonium chloride.
Sinoright, as a professional supplier of chemical products and food additives, provides food-grade ammonium chloride products that comply with FCC (Codex Alimentarius) standards and are ISO 22000 food safety management system certified, demonstrating excellent performance in purity control, heavy metal residues, and microbiological indicators.

Conclusion
In summary, ammonium chloride is a common food additive. It is added to dough, used in baking and yeast fermentation, and employed as a flavoring, thus playing an important role in food processing.
Although ammonium chloride is a safe food additive, its usage must be strictly controlled in food processing to ensure food quality and safety.
