The average intake of vegetables in Ireland falls below the recommendations of Bord Glas and FSAI.

Lactic acid bacteria (LAB) are well-known in food for their benefits such as improvement of the nutritional value of food and improvement of the digestion of lactose. Vegetable consumption could be enhanced by promoting a novel snack fermented carrot product that would provide the healthy benefits of vegetables coupled with the benefits of the probiotic lactic acid bacteria. Two varieties of carrots, Amsterdam (baby carrots) and Nantes half-long were chosen for this study due to their availability throughout the year. Carrot sticks (90 mm x 5 mm x 5 mm) were produced to standardize and reduce the heterogeneity of the raw material. The initial levels of total viable counts on Amsterdam carrots were established at 2.0x105 cfu/g. Blanching treatments of a minimum of 40 seconds were required to inactivate the initial microbiological load. There were no significant differences (p
