Zinc lactate (E325a) – what is it?
Zinc lactate, designated as E325a, is a zinc salt of lactic acid, mainly used as a preservative and acidity regulator in the food industry. Zinc, being one of the key micronutrients, plays an important role in many biological processes, and its presence in zinc lactate also has protective and stabilizing properties in food.
Properties of zinc lactate (E325a)
Zinc lactate acts as an effective preservative that prevents microbial growth in food products, which helps extend their shelf life. In addition, E325a exhibits pH-stabilizing properties, which helps maintain proper acidity in foods, affecting taste and texture. Zinc contained in zinc lactate is also valued for its health properties, as zinc is an essential micronutrient that supports immune system function and metabolism.
Use in food products
E325a is used in a wide range of food products where acidity stability and control of microbial growth are important. It is used in the production of beverages, such as fruit juices and isotonic drinks, where it acts as a pH stabilizer, ensuring the freshness and quality of the products. Zinc lactate is also used in dairy products such as yogurts and cheeses, where it helps control pH and promote proper product texture.
In addition, E325a can be found in meat products such as cold cuts and canned meats, where it prevents bacterial growth and helps preserve food quality for a longer period of time.
Health benefits and safety of use
Zinc lactate is considered a safe food additive. As a source of zinc, it supports health, especially in the context of the immune system, skin and metabolism. Zinc is also important in wound healing processes and in protecting cells from oxidative stress. Because it is used in small amounts, it poses no health risks.
Why is E325a valued?
Zinc lactate (E325a) is valued for its preservative properties, pH stabilizing properties and the health benefits of zinc. Thanks to these qualities, it is widely used in food, ensuring long-lasting freshness, high product quality and supporting consumer health.
