Food grade citric acid or pure citric acid is safer

Of course, food-grade citric acid.

It's safer, and I've only recently figured out food grade and industrial grade, and it's analytically pure.

grade and other non-food grade differences. Food grade refers to the citric acid after the special process has been removed from the components that may be harmful to the human body, and the analytical pure grade of citric acid, even if the purity is high, can only indicate that it contains less impurities, but this high-purity analytical pure citric acid may contain ingredients that are potentially harmful to the human body. In recent years, the state has raised food safety to a very high level of supervision, and even if it is expensive, it should still use food grade.

I'll give you another example, such as concentrated sulfuric acid.

Bar, it turns out that food production enterprises are using industrial-grade sulfuric acid, and this year's latest food additives.

The national standard for sulfuric acid (i.e., food-grade concentrated sulfuric acid) has also been issued and implemented (standard number: GB 29205-2012 National Food Safety Standard Food Additives Sulfuric Acid), while the national standard number for industrial grade is GBT534-2002 Industrial sulfuric acid, you can search on it and compare their differences. The above is a personal suggestion for reference only, I hope it can help you. Ha ha.

*The safety comparison of food-grade citric acid and analytical pure citric acid needs to be considered in terms of purity and use**.

1.In terms of purity: Pure citric acid is analyzed at a higher purity, generally above, which means that it contains very few impurities.

However, the purity requirements of food-grade citric acid are relatively low, generally at 95% and 98%, allowing a certain amount of impurities, such as sodium citrate. An increase in purity does not necessarily mean that pure citric acid is safer to analyze, as high-purity pure citric acid may contain some ingredients that are potentially harmful to humans.

2.Uses: Food-grade citric acid is a product that has been processed by a special process to remove ingredients that may be harmful to the human body, so it is more suitable for use as a food additive. The analysis of pure citric acid is mainly used for non-food purposes such as analysis and inspection.

On the whole, food-grade citric acid may theoretically be safer if it meets the standards of food additives. However, this does not mean that pure citric acid is unsafe for analysis, as it is primarily intended for non-food use and should be used under specific conditions in strict accordance with the relevant usage guidelines. For consumers, no matter what kind of citric acid is used, it should not be consumed in excess, otherwise it may have an impact on physical health.

Finally, it is important to emphasize that any chemical is safe under certain conditions, and excessive or improper ingestion can cause health hazards. Therefore, when using any food additives or chemicals, the relevant regulations and guidelines should be followed to ensure that the intake and use are within a safe range.

1. Citric acid is mainly used as acidulant, solubilizer, buffer, antioxidant, deodorant, flavor enhancer, gelling agent, toner, etc. In addition, citric acid also has the effects of inhibiting bacteria, protecting color, improving flavor, and promoting sucrose conversion.

2. Citric acid also has chelation and can remove certain harmful metals. Citric acid prevents oxidation caused by enzyme catalysis and metal catalysis, thereby preventing the discoloration and flavor of frozen fruits.

3. In terms of food additives, it is mainly used for carbonated drinks, fruit juice drinks, lactic acid drinks and other cool drinks and pickled products, and its demand is subject to changes in seasonal climate. Citric acid accounts for about 2 3 of the total consumption of acidulants.

4. Adding citric acid to canned fruits can maintain or improve the flavor of fruits in the collection, increase the acidity of some fruits with low acidity, weaken the heat resistance of microorganisms and inhibit their growth, and prevent bacterial expansion and destruction that often occur in canned fruits with low acidity.

Citric acid is an edible acid, which can enhance the normal metabolism in the body, and the appropriate dose is harmless to the human body. The addition of citric acid to some foods tastes good and can promote appetite, and citric acid is allowed in jams, beverages, canned foods and candies in our country.

It can promote the excretion and deposition of calcium in the body, such as long-term consumption of foods containing citric acid, which may lead to hypocalcemia.

Children present with nervous system instability, excitability, and autonomic disorders; In adults, there are tetany, muscle spasms, paresthesias, itching, and gastrointestinal symptoms.

It can adjust the acidity, inhibit the reproduction of some bacteria, and play a certain role in preservative.

Food additives, some beverages, food are there, lemon flavor.

An edible food additive.
