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]. Seiler, D.A.L.

Bacillus amyloliquefaciens, B . and Voysey, P.A. Fifty percent of the total samples (160 samples sprayed with ethanol 1.5 g/100 g of muffin) had MFSL higher than 70 days. The factors that govern the rate of freshness loss in bread during storage are mainly divided into two groups; those attributed to microbial attack, and those that are result of a series of slow chemical or physical changes which lead to the progressive firming up of the crumb, commonly referred to as 'staling'. Both of my last loaves ended up with sticky middles and a yeasty smell. Journal of Cereal Science, 1, 297303. Annales de Chimie Physique ,36, 490. Epub 2012 Apr 14.
