While maintaining a low pH in sauces, dressings, and condiments helps prevent the growth of common spoilage microorganisms and pathogens, it does not protect against them all – for example, Lactobacillus spp, and yeast and molds like Mucor spp and Saccharomyces spp.
In fact, some bacteria thrives under low pH conditions and without oxygen, causing havoc with food products. Which is another area where PURASAL® and PURAC® - our natural L-lactic acid - can help, with a proven high efficacy against bacteria that are more resistant to many other acids.
