What to Know About Lactic Acid in Food

Understanding Lactic Acid in Food

This post was written with Consensus AI Academic Search Engine – please read our Disclaimer at the end of this article. Lactic acid is a naturally occurring organic acid that plays a significant role in various food products. It is primarily produced by lactic acid bacteria (LAB) through the fermentation process and is known for its preservative and flavor-enhancing properties. This article explores the diverse applications and health benefits of lactic acid in food.

Role in Oral Health

Lactic acid has been shown to have beneficial effects on oral health, particularly in companion animals. Studies have demonstrated that lactic acid supplementation in pet food can significantly inhibit the accumulation of dental plaque, calculus, and tooth stains in cats. This suggests that lactic acid can be an effective additive in maintaining oral hygiene in pets1.

Impact on Sleep Quality

Lactic acid bacteria-containing foods have been linked to improvements in sleep quality. A study involving lactic acid bacteria derived from Lactobacillus helveticus showed that continuous consumption of these foods improved sleep efficiency and overall sleep quality. This indicates that lactic acid bacteria can be a useful dietary component for enhancing sleep, particularly in populations with sleep disorders2.

Probiotic and Immunostimulatory Effects

Lactic acid bacteria are known for their probiotic properties, which include transient colonization of the intestine and exerting beneficial health effects. These effects include improved lactose digestion, enhanced immune response, and reduced incidence of intestinal tumors. The immunostimulatory effects of lactic acid bacteria have been observed in clinical trials, highlighting their potential in boosting host resistance and overall health3 6.

Benefits for Gastrointestinal Health

Lactic acid bacteria have been studied for their effects on gastrointestinal health, including the management of gastroesophageal reflux symptoms. Ingesting heat-killed Lactobacillus johnsonii has been shown to improve heartburn symptoms, suggesting that lactic acid bacteria can be beneficial in managing digestive health issues4.

Effects on Glycemic Control and Antioxidant Status

In patients with type 2 diabetes, lactic acid-containing foods have been found to positively affect glycemic control and antioxidant status. Consumption of synbiotic bread containing lactic acid resulted in significant improvements in HbA1c levels and antioxidant biomarkers, indicating potential benefits for managing diabetes5.

Influence on Iron Absorption

While lactic acid-fermented foods have been associated with increased iron absorption, studies have shown that the addition of viable lactic acid bacteria does not significantly affect iron absorption from lactic acid-fermented meals. This suggests that the benefits of lactic acid in iron absorption may be limited to certain conditions or formulations7.

Enhancing Growth and Immune Response in Aquatic Species

Lactic acid bacteria have also been used in aquaculture to promote growth and enhance immune responses in fish. Studies on Persian sturgeon and beluga fry have shown that lactic acid bacteria can improve growth rates, digestive enzyme activity, and disease resistance, making them valuable in aquaculture practices8 9.

Conclusion

Lactic acid and lactic acid bacteria play a crucial role in food preservation, health enhancement, and disease prevention. Their applications range from improving oral health and sleep quality to enhancing immune responses and managing diabetes. As research continues, the potential of lactic acid in various health and dietary applications is likely to expand, offering new opportunities for improving human and animal health.
