Shelf-life factors such as moisture content (3542%) and water activity of crumb (0.900.95) of most yeast-leavened bakery products make them well suited for the development and growth of rope-causing bacteria and hence susceptible to rope spoilage. . [Citation3,Citation16,Citation17,Citation18], Shelf life extension of cake and other baked products may be achieved using single ingredient or process change, or a combination of many alternative changes according to food legislation, ingredient availability and cost, consumer acceptance, and social trends. Ropiness is associated with a patchy discoloration and a stringy bread crumb, and characterized by an unpleasant sweetish odor resembling rotting melons or pineapples that is caused by the release. Try using a different box mix with the same ingredients you used previously, and if it doesn't happen again, I believe you'll have found your culprit. Both methods, pasteurization and the use of chemical preservatives, have been extensively used in bakery products for MFSL extension. I can't get a good photo of it but my mother made brownies and I offended her by suspecting rope spoilage when I pulled one of the pieces apart and it had many, many thin white strands between the pieces when it was pulled apart. and DAppolonia, B.L. enced in slightly acidified groat bread or fine bakery ware.

Journal of frontiers. 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].
