Citric acid is an important organic acid, also known as citric acid, colorless crystals, often containing a molecule of crystal water, odorless, with a strong sour taste, easily soluble in water. Its calcium salt is more soluble in cold water than hot water, which is often used to identify and isolate citric acid. Anhydrous citric acid can be obtained by controlling the appropriate temperature during crystallization. It has many uses in industry, food industry, cosmetic industry, etc.

However, citric acid is widely distributed in nature, citric acid is present in plants such as fruits and animal bones such as lemons, oranges, pineapples, muscles, blood naturally. Citric acid is a synthetic substance prepared from fermented sugars, molasses, and starch, which can be divided into two kinds of anhydrous and hydrated grapes. Pure citric acid is colorless transparent crystal or white powder, odorless and has an attractive sour taste.

You can refer to this data: Citrus fruits are rich in citric acid, especially lemons and limes - they contain a lot of citric acid, and after drying, the content can reach 8% (the content in the juice is about 47% g/L). In citrus fruits,Starch sugar engineering design company, the content of citric acid is between 0.005mol/L of orange and grape and 0.30mol/L of lemon and lime. It varies with the content of different varieties and plants.

Citric acid is an edible acid, which can enhance the normal metabolism in the body. Jining citric acid is harmless to the human body in an appropriate dose. After adding citric acid to some foods, the taste is good, and the system works continuously , and it can promote appetite. Lemon---food additive monopoly, allows the use of citric acid in jams, beverages, cans and candies. Although citric acid has no direct harm to the human body, it can promote the excretion and deposition of calcium in the body. For example, long-term consumption of foods containing citric acid may lead to hypocalcemia.

In addition, based on the effect of citric acid on calcium metabolism, the syrup engineering design , people who often eat canned food, beverages, jams, and sour candies, especially children, should pay attention to calcium supplementation, drink more fish head, fish bone soup, eat small Shrimp and other foods with high calcium content, so as not to cause insufficient blood calcium and affect health, gastric ulcer, hyperacidity, dental caries and diabetes patients should not eat citric acid regularly. Citric acid cannot be added to pure milk, otherwise it will cause pure milk to coagulate. The dairy industry often mixes citric acid into a solution of about 10% to become a low-concentration milk solution, which should be added with rapid stirring.
