El ácido láctico es utilizado en varios productos como regulador de acidez. Aunque puede obtenerse de la lactosa (azúcar de la leche), la mayor parte del ácido láctico empleado comercialmente deriva del uso de bacterias como la Bascillus acidilacti, Lactobascillus delbueckii o Lactobascillus bulgaricuswhey para fermentar fuentes de carbohidratos como la maicena y las papas. Así, lo que comúnmente se denomina "leche ácida" en alimentos vegetarianos o vegan tienen ácido láctico como ingrediente.
asi que para no arriesgarse lo mejor seria llamar a las compañias fabricantes de cada producto para preguntar, pero tambien significa que si lo han consumido accidentalmente no hay mucho de que procuparse

Lactic acid is primarily found in sour milk products, such as: koumiss, leban, yogurt, kefir and some cottage cheeses. The casein in fermented milk is coagulated (curdled) by lactic acid.
Although it can be fermented from lactose (milk sugar), most commercially used lactic acid is derived by using bacteria such as Bacillus acidilacti, Lactobacillus delbueckii or Lactobacillus bulgaricus to ferment carbohydrates from nondairy sources such as cornstarch, potatoes and molasses. Thus, although it is commonly known as "milk acid", vegan products can contain lactic acid as an ingredient.
Lactic acid may also be found in various processed foods, usually either as a pH adjusting ingredient, or as a preservative (either as antioxidant or for control of pathogenic micro-organisms). It may also be used as a fermentation booster in rye and sourdough breads.[2]
Lactic acid is also present in wheat beers, especially lambic, due to the activity of Pediococcus damnosus.[3]
Lactic acid is widely used for inhibiting pathogenic bacteria like E.coli, Salmonella, Campylobacter and Listeria on animal carcasses like beef, pork and poultry during the slaughtering process.
Potassium lactate, sodium lactate and calcium lactate are the neutralized salts of lactic acid. Potassium lactate is used in many fresh and cooked meat products for shelf life control, color preservation and reduction of sodium content. Sodium lactate has a mild saline taste and is therefore suitable for flavour enhancement in meat products as well. Sodium lactate is being produced as liquids as well as powders. Calcium lactate is popular for fortification and improved texture in emulsified meat products like frankfurters.[4]
