Crumpets
Crumpets are particularly popular in the United Kingdom and Australia. Crumpets have high moisture and high water activities, consequently, they have a short shelf life of usually less than 6 days. The another reason leading to decreasing shelf life is that flour used in the production of crumpets will invariably contain a low number of Bacillus cereus spores. In the cooking process, the bottom of the crumpets receives a high heat treatment, but the rest of crumpet receives a lower heat treatment, which bacillus spores easily survive. NisinA® can effectively inhibit Bacillus cereus for a longer shelf life of Crumpets.

NisinA™ - Inhibits bacillus cereus in Crumpets

Crumpets are popular products in UK, Australia and New Zealand, produced on a hot plate from a flour batter with yeast or an aerating agent or both to give them a raised profile and open texture. They are toasted before eating. Crumpets have a non-acid pH (pH 6), high moisture (48–54%) and high water activity (0.95–0.97). The product is sold at ambient temperature and has a shelf life of five days. There have been a number of food poisoning outbreaks due to the growth of Bacillus cereus in crumpets, particularly in Australasia. Flour used in the manufacture of crumpets invariably contains low numbers of B. cereus spores that are not killed during the hot plate cooking process. During the 3–5 day ambient shelf life of the product, B. cereus can increase from undetectable levels to > 105 cfu/g – sufficient bacteria to cause food poisoning.

Addition of NisinA to the batter mix at 120 mg/kg to prevent the growth of B. cereus has received regulatory approval in Australia and New Zealand.
