How do you get Sodium Propionate or E281?

To obtain the E281 additive, the following steps are followed

Identify the raw material The E281 additive, also known as sodium lactate, is obtained from the fermentation of natural sugars, such as cane sugar or beet sugar.

Fermentation The process of obtaining sodium lactate involves the fermentation of these natural sugars by a bacteria called Lactobacillus. This bacteria converts sugars into lactic acid.

Purification and neutralization Once the lactic acid is obtained, it undergoes a purification process to eliminate impurities. It is then neutralized using sodium hydroxide, thus forming sodium lactate.

Filtered The sodium lactate obtained is filtered to eliminate any solid particles that may be present.

Drying The filtered product undergoes a drying process to eliminate any trace of moisture and obtain the additive in powder or granule form.

Packaging and storage Finally, the E281 additive is packaged in suitable containers and stored in optimal conditions for subsequent distribution and use in the food industry. It is important to keep in mind that this process is at an industrial level and must be carried out by specialized and certified companies, since it involves quality control techniques and measures to ensure the purity and safety of the additive.

Food use of Sodium Propionate E281

The additive E281, also known as sodium propionate, is a preservative used in the food industry. Below are some of the possible food uses of this additive

Bakery Products Sodium propionate is commonly used in breads and baked goods to extend their shelf life. It helps prevent the growth of mold and other microorganisms, which is especially beneficial in products that tend to be susceptible to degradation.

Cheese In some cheeses, sodium propionate is used as a preservative to prevent the growth of undesirable bacteria and fungi. This helps maintain the quality and durability of the cheeses for a longer period.

Recommended consumption of Sodium Propionate E281

The additive E281, also known as sodium propionate, is a preservative used in foods to extend their shelf life and prevent the growth of bacteria and molds. The maximum recommended consumption of the E281 additive varies according to the regulations of each country and food safety authorities. In the European Union, the Expert Committee on Food Additives (JECFA) has established an acceptable daily intake (ADI) of 0-25 mg/kg body weight for sodium propionate. This means that a 60 kg person can consume up to 1500 mg of sodium propionate per day, without it being considered harmful to health. However, it is important to note that excessive consumption of food additives can have negative health effects. Therefore, it is recommended to follow the daily intake guidelines established by food safety authorities and limit exposure to additives in general, including the additive E281.
