They also function as water binders because their principal components (such as starch, protein, sugars, fat) have pronounced moisture-absorbing properties Starch, when added to the batter in amounts of 1 to 5 % increases batter viscosity and improves the volume symmetry, grain and texture of the resultant cake. The same is applicable. After processing these results discarding the insignificant factors, the following models for the MFSL were derived, expressed in relative values of significant factors: (2) (3) (4), The models of the fourth and fifth design could not be expressed by the relative equations y4 and y5 , since there were no results for the majority of muffin samples, which showed unlimited shelf life. Nevertheless, microbiological spoilage of these products occurs, resulting in substantial economic losses. The selected ingredients were sugar, glycerol, potassium sorbate, and an acidic agent (citric acid, sodium diacetate, and tartaric acid). Avrami, M. (1940) Kinetics of phase change, II.

Leung, H.K., Magnuson, J.A. Rope spoilage is a bread disease which consists in bacterial decomposition of the bread crumb. [Citation3,Citation4] Although mould and mould spores are destroyed by the heat of the baking process, due to thermal inactivation, post-baking contamination occurs from the mould spores present in the atmosphere, during subsequent handling operations such as cooling, finishing, and wrapping. Toss the cake? Increasing consumer demand for preservative-free products and global warming may increase the occurrence of ropy spoilage. Implementation and enforcement of good manufacturing practices, pre-requisite programs, food safety systems are necessary for reducing the proliferation of rope-causing bacteria. 4860.
