A mathematical model has been developed by scientists in Denmark to manipulate the chance from Clostridium botulinum in sure meals.

The tool might maybe also very correctly be ancient in constructing or reformulation of current and lightly preserved seafood and poultry products that enact no longer enhance the expansion of Clostridium botulinum. Botulism poisoning is a indispensable but uncommon sickness caused by toxins produced by Clostridium botulinum bacteria.

Researchers on the Nationwide Meals Institute, Technical College of Denmark developed and evaluated the model for non-proteolytic Clostridium botulinum to predict the affect of temperature, salt/water task (aw), pH, acetic, benzoic, citric, lactic and sorbic acids on negate responses.

For refrigerated products, pointers for controlling Clostridium botulinum indicate that water in them need to bear a salt whine of no longer lower than 3.5 percent but this hampers efforts to make products with diminished salt.

Salt reduction narrate


If food producers desire to launch devices that have less salt, they must enact laboratory experiments to document that a switch in recipe is no longer going to compromise food security.

Predictive food microbiology fashions can simulate the blended affect of various product characteristics and storage cases as previously confirmed with Listeria monocytogenes.

The developed model can predict whether a particular recipe for chilled products can prevent the expansion of Clostridium botulinum and manufacturing of the toxin. This would no longer suggest it goes to entirely change narrate sorting out, however the series of tests for product constructing or reformulation might maybe also be diminished.

Several mathematical fashions for the expansion or toxin formation of Clostridium botulinum exist but they don’t encompass the preservatives acetic, benzoic, citric and sorbic acids that are crucial for lightly preserved seafood and tons of alternative products.

Researchers ancient four Clostridium botulinum isolates that can’t affect the harmful toxins as surrogates for predicting the absence of negate and of toxin formation in various recipes, primarily based fully mostly on the peek published in the Global Journal of Meals Microbiology.

Review and doubtless expansion


For model overview, 40 narrate tests with current and lightly preserved seafood bear been performed. It modified into evaluated with 94 negate rates and 432 time to toxin formation records from scientific literature for seafood, poultry, meat, pasta and willing meals.

The model precisely predicted 93.8 percent of the expansion responses with 5.6 percent being fail-safe and lower than 1 percent fail-harmful. Fail-safe is when negate modified into predicted when none modified into seen and fail-harmful is rarely any negate predicted when negate modified into viewed.

The peek modified into supported by the Danish Meals Industry Agency as phase of a project between DTU Meals and Royal Greenland Seafood A/S.

More records are wished to evaluate the model with meat, ready meals and vegetable products. Future research might maybe also lengthen the model with phrases for smoke substances/phenol, modified atmosphere/Carbon dioxide, nitrite and nisin to expand its applicability for smoked and modified atmosphere packed food, cured meat and processed cheese.
