What Is Citric Acid Powder

Citric acid, also known as lemon acid, is a weak organic acid with the chemical formula of C6H8O7. Citric acid is a naturally occurring acid found in a variety of fruits and vegetables. Citric acid can exist in anhydrous or monohydrate form. The crystal form of citric acid varies due to different crystallization conditions. It can be decomposed into a variety of products when heated and can react with acids, alkali, glycerol, etc.

As a versatile organic acid, granular citric acid has a wide range of applications, from food and beverages to pharmaceuticals and cleaning products. It is safe and considered a natural chemical as it is found in many natural ingredients. In the food and pharmaceutical industries, citric acid is usually supplied in powder or crystal form.

Food Grade Citric Acid

Because food grade citric acid has a mild and refreshing sour taste, it is widely used in the manufacture of various beverages, sodas, wines, candies, snacks, biscuits, canned juices, dairy products and other foods. Among all organic acids in the market, citric acid accounts for more than 70% of the market. So far, there is no sour agent that can replace citric acid.

As an edible acid, citric acid can enhance normal metabolism in the body and is harmless to the human body in appropriate doses. Adding lemon acid to some foods tastes good and can increase appetite. However, food grade citric acid can have a negative impact on calcium metabolism. Therefore, eat a small amount and pay attention to calcium supplements, especially for children. In addition, granular citric acid can’t be added to pure milk, otherwise it will cause the pure milk to coagulate.

What Are Applications of Citric Acid For Food

Citric acid is the largest organic acid produced by biochemical methods in the world. Citric acid and salts are one of the pillar products of the fermentation industry and are mainly used in the food industry, such as sour agents, solubilizers, buffers, antioxidants, deodorizer, flavor enhancer, gelling agent, toner, etc.  

Used as food sourness regulator. Citric acid is a natural sourness regulator that can be used to adjust the acidity and taste of food. Citric acid powder is an important acidity regulator in beverages, juices, yogurt, preserves and other foods.    

Used as food preservative. Citric acid acts as a natural preservative and can be used to maintain the freshness and quality of food. It is a commonly used preservative in pastries, bread, cheese, seasonings and other foods.

As food emulsifier. Citric acid acts as an emulsifier and can be used to adjust the consistency and texture of foods. The food additive is a commonly used emulsifier in foods such as ice cream, cream, and chocolate.

As food acidifier. It can be used to increase the acidity and taste of food. In foods such as jam, fruit vinegar, and sauerkraut, citric acid is a commonly used acidifier, accounting for about 2/3 of the total consumption of sour agents. Adding citric acid to canned fruits can maintain or improve the flavor of the fruit, increase the acidity of some fruits with lower acidity when canned, weaken the heat resistance of microorganisms and inhibit their growth, and prevent the growth of fruits with lower acidity.

Used as food antioxidants. Citric acid can be used as a natural antioxidant. Its chelating effect and pH adjustment properties enable it to increase antioxidant performance, inhibit enzyme activity, and extend the shelf life of food in the processing of quick-frozen foods. Citric acid is a commonly used antioxidant in meat products, soy products, biscuits and other foods.

Citric acid is widely used in the food industry. It can not only improve the taste and quality of food, but also extend the shelf life of food. However, it should be noted that the amount of citric acid used in food should be controlled within an appropriate range to avoid adverse effects on human health.

Applications in Industrial Fields

Used in water treatment industry. Citric acid has the functions of sterilizing and adjusting the pH value of water in water treatment. Its acidity can change the pH of cells and affect the normal metabolism of bacteria. Acidic high concentrations of hydrogen ions can also alter bacterial biological activity and directly damage cells.

Used in chemical reagents. In chemical technology, citric acid can be used as a reagent for chemical analysis, experimental reagents, chromatographic analysis reagents and biochemical reagents. It can also be used as a complexing agent and masking agent to prepare buffer solutions.

Used in detergents. Using citric acid or citrate as a builder can improve the performance of washing products, quickly precipitate metal ions, prevent pollutants from reattaching to fabrics, maintain the necessary alkalinity for washing, disperse and suspend dirt and ash, so as to improve surfactant performance. Citric acid can also be made into a formaldehyde-free anti-wrinkle finishing agent, which can be used for anti-wrinkle finishing of pure cotton fabrics.

Used in cosmetics, citric acid has the effect of preventing and eliminating skin pigmentation. Citric acid is a type of fruit acid. Its main function is to accelerate the renewal of cuticles. It is often used in lotions, creams, shampoos, whitening products, anti-aging products, acne products, etc.

Used as additive for poultry and livestock. Adding citric acid to piglet feed can lead to early weaning, increase feed utilization by 5% to 10%, and increase sow litter size. Adding 1% to 2% citric acid to the diet of growing and finishing pigs can increase daily weight gain, reduce feed-to-meat ratio, increase protein digestibility, reduce back fat thickness, and improve meat quality and carcass characteristics.

Used in fungicides. Citric acid has a good effect on killing bacterial spores, and can effectively kill bacterial spores contaminated in the pipelines of hemodialysis machines.

Used in the pharmaceutical industry. Citric acid, also known as citrate, requires calcium ions to participate in the formation of prothrombin activator and subsequent coagulation process. Citrate ions and calcium ions can form a soluble complex that is difficult to dissociate, thus reducing the concentration of calcium ions in the blood and hindering blood coagulation. Used as an extracorporeal anticoagulant during blood transfusions or laboratory blood sample anticoagulation.

More About Citric Acid

Soluble in water, ethanol, ether, insoluble in benzene, slightly soluble in chloroform. The aqueous solution is acidic.   

At room temperature, citric acid appears as colorless translucent crystals, white particles or white crystalline powder. It is odorless, extremely sour, and slightly deliquescent in humid air.

It can exist in the form of anhydrous citric acid or monohydrate citric acid. When citric acid crystallizes from hot water, it forms anhydrous. When it crystallizes from cold water, it forms monohydrate. The monohydrate decomposes to the anhydrate when heated to 78 °C. At 15°C, citric acid can also be dissolved in absolute ethanol.

Citric acid E330 is fully compliant with food grade requirements, which has good performance in actual use, mainly in terms of safety. The raw materials for preparing citric acid are all derived from natural foods, so it is a safe food-grade microorganism.

  1. Determine the dosage of citric acid according to specific needs. Use citric acid powder or citric acid solution to add the appropriate amount of citric acid according to the recipe for making food, medicine, cosmetics or cleaning products.
  2. Pay attention to the storage of citric acid and store it in a dry and cool place to avoid moisture.
  3. When preparing food, ensure that citric acid is used in accordance with food regulations and safety standards.
  4. Although citric acid is generally considered safe, it still needs to be used according to the specific needs and guidance of the product. In industrial and commercial applications, relevant regulations and standards should be followed to ensure product quality and safety.

Natural citric acid is widely distributed in nature. Natural lemon acid is found in plants such as lemons, citrus, pineapples and other fruits, and in the bones, muscles, and blood of animals. Synthetic citric acid powder is produced by fermenting sugary substances such as sugar, molasses, starch, and grapes. Many fruits and vegetables, especially citrus fruits, contain high amounts of citric acid, especially lemons and limes. They contain large amounts of lemon acid, up to 8% after drying. This content varies with different cultivars and plant growth conditions.

Typically, farinaceous substance is the main source of citric acid. First, crush the farinaceous raw materials, then add an appropriate amount of water to the crushed raw materials and stir. The mixture is fermented, and the filtrate is obtained by filtration after fermentation. Calcium carbonate is added to the filtrate to cause neutralization reaction, and calcium citrate is filtered out. Calcium citrate is acidolyzed with sulfuric acid and filtered. The filtrate is decolorized by ion exchange, then concentrated, crystallized, and dried to obtain citric acid powder.
