PURAC offers the deli salad industry PURAC Fresh for:

·         Listeria inhibition;

·         Shelf life;

·         pH regulation;

·         Flavor improvement

 

Listeria inhibition

PURAC Fresh, a liquid lactic acid based product is used in deli salads to control the outgrowth of Listeria monocytogenes. Previous studies have shown that its optimised formulation suppresses the proliferation of this pathogen at a pH even up to 5.5. The recent development of the PURAC Fresh Listeria Control Model supports this study. This interactive model helps to predict the growth of Listeria in e.g. deli salads and to make them safer.

Shelf life

Microorganisms, such as yeasts and lactic acid bacteria, can cause spoilage in deli salads. PURAC Fresh controls the growth of a broad range of microorganisms, resulting in an improved shelf life.

 

pH regulation

PURAC Fresh is available at two pH levels, allowing for flexible pH adjustment of deli salads. The buffering capacity of both products ensures a stable pH of the salad throughout production, which gives ease of use and comfort.

 

Flavor improvement

The use of food acids in deli salads often limits the creativity of product developers, since the products tend to become too sour. PURAC Fresh is optimised for giving a mild acid flavour to food products, while maintaining food safety and the desired shelf life. Furthermore, lactic acid is known for enhancing certain flavors such as bacon, tomato, green herbs and cheese.
