Rope spoilage is a bread disease which consists in bacterial decomposition of the bread crumb. Silliker, J.H. ), it is very difficult to investigate the influence of a single component on the shelf life in combination with the behavior of other components of the mixture. Following are examples of some guidelines which may help in reducing the incidence of rope spoilage. Bechtel, D. B., Pomeranz, Y., & de Francisco, A. Rapid and alternative screening method for microbiological analysis. 11933.

Manipulation of ingredients, which slow the rate of moisture loss during storage, such as sugar, glycerol, salt and preservatives, is a powerful tool, which could lead to a significant inhibition of cake microbial growth and therefore, sensible extension of mould-free shelf life could be achieved.[Citation3,Citation4,Citation9,Citation19]. The preservative used was potassium sorbate (Cheminova) and the acidic agents were citric acid (ADM), tartaric acid (ADM), and sodium diacetate (Borniger). What problems does the food industry have with the spore-forming pathogens Bacillus cereus and Clostridium perfringens? I. 180). Prevention of growth of approximately 10(4) rope-producing B. subtilis G1 spores per cm(2) on bread slices for more than 15 days was observed when heat-treated cultures of Lactobacillus plantarum E5 and Leuconostoc mesenteroides A27 were added.
