As bread is a very important staple food, its spoilage threatens global food security. It's a key indicator in the food and chemical industries influencing many aspects of processing, shelf life and overall quality. Journal of Textural Studies ,4, 292322. Applied Microbiology, These can increase the pH, limiting effectiveness of preservatives. 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. The values of variables (design factors) are given in Table 2.

Functional Properties and Sustainability Improvement of Sourdough Bread by Lactic Acid Bacteria. Journal of Disclaimer. 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.
