★Food Industry
Citric acid is known as the first edible sour agent, and China GB2760-1996 is the requirement for the allowable use of food acidity regulators. In the food industry, it is widely used as sour agent, solubilizer, buffer, antioxidant, deodorant and sweetener, chelating agent, and its specific uses are too numerous to enumerate. 
1. Drinks
Citric acid juice is a natural ingredient that not only imparts fruit flavor, but also has solubilizing buffering and anti-oxidation effects. It harmonizes and blends sugar, flavor, pigment and other ingredients in beverages to form a harmonious taste and aroma, which can increase resistance. Bactericidal effect of microorganisms.
2. Jams and jellies
Citric acid works in jams and jellies similar to what it does in beverages, adjusting the pH to make the product sour, the pH must be adjusted to be most suitable for a very narrow range of pectin condensation. Depending on the type of pectin, the pH can be limited between 3.0 and 3.4. In the production of jam, it can improve the flavor and prevent the defects of sucrose crystal sand.
3. Candy
Adding citric acid to candy can increase acidity and prevent oxidation of various ingredients and sucrose crystallization. A typical sour candy contains 2% citric acid. The process of boiling sugar and massecuite cooling is to connect acid, coloring, and flavor together. Citric acid produced from pectin can adjust the sour taste of candy and increase gel strength. Anhydrous citric acid is used in chewing gum and powdered foods.
4. Frozen food
Citric acid has the properties of chelating and adjusting pH, which can strengthen the effect of antioxidant and enzyme inactivation, and can more reliably ensure the stability of frozen food.
★Cosmetics industry
Citric acid is a kind of fruit acid. Its main function is to speed up keratin renewal. It is often used in lotions, creams, shampoos, whitening products, anti-aging products, and acne products. The renewal of keratin is helpful for the exfoliation of melanin in the skin, the reduction of pores, and the dissolution of blackheads.
★Pharmaceutical industry
Citric acid is widely used in a variety of nutritional oral liquids, and the pH of the buffer is 3.5~4.5 to maintain the stability of the active ingredients and enhance the antiseptic effect. Combined with citric acid and fruity taste, it gives people a sweet and sour taste to mask the bitter taste of medicine, especially for traditional Chinese medicine preparations. Adding 0.02% citric acid to the liquid component can form a trace amount of iron-copper complex and delay the activity. Degradation of ingredients. Chewable tablets containing 0.1%~0.2% citric acid can improve the flavor and lemon flavor.
