Additionally, lactic acid acts as a humectant, attracting and retaining moisture in the skin, making it an excellent choice for dry or dehydrated skin.
The Science Behind Lactic Acid
The chemical formula of lactic acid is C3H6O3. It exists in two forms: L-lactic acid (levorotatory) and D-lactic acid (dextrorotatory). Both forms are found in nature, with L-lactic acid being the dominant form. Lactic acid is a colorless, syrupy liquid with a sour taste and a distinct odor. It is soluble in water, alcohol, and ether.
When consumed, lactic acid is rapidly metabolized by the body. The liver converts it into glucose, providing a source of energy. This metabolic process ensures that lactic acid does not accumulate in the body and cause any harm.
Interestingly, lactic acid is not only produced by humans but also by certain bacteria in the gut. These bacteria, known as lactic acid bacteria, play a crucial role in maintaining a healthy digestive system. They help break down food, produce essential vitamins, and create an acidic environment that inhibits the growth of harmful bacteria. Consuming foods rich in lactic acid, such as yogurt or fermented vegetables, can promote a balanced gut microbiome and support overall digestive health.
Common Sources of Lactic Acid
Lactic acid is naturally present in various foods, including fermented products such as yogurt, sauerkraut, and kimchi. It is also produced during the fermentation of vegetables, fruits, and grains. In the food industry, lactic acid can be derived from both animal and plant sources.
Traditionally, lactic acid was obtained from milk, making it non-vegan. However, advancements in biotechnology have enabled the production of lactic acid through bacterial fermentation of plant-based carbohydrates. This method uses vegan-friendly bacteria cultures, such as Lactobacillus plantarum or Lactobacillus delbrueckii, to convert plant sugars into lactic acid.
Moreover, lactic acid has found applications beyond the food and skincare industries. It is also used in the production of biodegradable plastics, as a pH regulator in pharmaceutical formulations, and as a cleaning agent in household products.
