Food Microbiol. and DAppolonia, B.L. After calculating the factors coefficients from the results obtained, the insignificant factors were discarded using the estimated confidence interval. The microbial shelf life is defined as the period in days in which the spoilage caused by microorganisms was first observed. R.P. This effect of the ingredients examined (sugar, salt, potassium sorbate, ethanol, acidic agents) is in accordance with that observed for bread and bakery products. Developments in the active packaging of foods, Trends in Food Science and Technology, 10, 7786. Part 1: Mould growth on bread. The effectiveness of preservation ranked high to low as: (combination of citric acid, potassium sorbate, ethanol, and pasteurization), (combination of citric acid, potassium sorbate, and ethanol), (combination of citric acid and potassium sorbate), (combination of sodium diacetate and potassium sorbate), (combination of tartaric acid and potassium sorbate). Food Technology ,43(4), 1437, 155. It can become a major health and economic concern fo. The MFSL of the majority of the samples (90%) was higher than 100 days, indicating that the combination of pasteurization with ethanol addition in this recipe was extremely effective. Any help is greatly appreciated. In addition, the models obtained may be used for predictions on the probable mould-free shelf life of muffins, within the variation intervals of factors (optimization parameter). Figure 1 Effect of acidic agent on the relative shelf life of muffin (sugar, glycerol, and K sorbate fixed at their maximum levels 120 g, 7 g, and 0.55 g, respectively, by 100 g of flour and starch). As with Staph. Applied Bacteriology, 70, 361371. Other sources of rope spoilage include shortenings, liquid whole eggs, sucrose, nonfat dry milk, liquid milk, liquid sweeteners (HFCS, 42 DE corn syrup, honey and molasses) and water. Washington, DC: American Public Health Association. Microbiology Technology Lebensm It's this tiny amount of tension that pulls the hem ever so slightly and creates a bumpy rope-like shape along the edge. When cut surfaces of the loaf are slowly pulled apart, thin strands or ropes can be seen stretching from one surface to the other. Dea), Gordon and Breach, New York, p. 387. Bechtel, W.G., Meisner, D.F. Bookshelf Addition of lactic acid . 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.

They also decrease starch gelatinization in cakes leading to a better cake structure with improved tenderness. Among the 320 muffin samples (64 statistical experiments), only 80 (25%) showed microbial spoilage and consequently definite MFSL The MFSL of these samples (with minimum sugar content and sprayed with ethanol 0.5 g/100g of muffin) are given in Table 6. Annales de Chimie Physique ,36, 490. The rest25% of the total samples (80 samples with maximum sugar content and sprayed with ethanol 0.5 g/100 g of muffin)showed MFSL higher than 50 days. Since muffin is a multicomponent mixture made by batter and additional optional ingredients (such as emulsifiers, fat, glycerol, milk, preservatives, ethanol, etc. However, compared to other categories of food products, bakery products rarely cause food poisoning. Guy, R.C.E, Hodge, D.G. SPECIAL. As bread is a very important staple food, its spoilage threatens global food security. It should be noticed the significant contribution of the three other factors, namely sugar, glycerol, and potassium sorbate to the improvement of MFSL, which is reflected in the values of their coefficients in the relative equations.
