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'. Any help is greatly appreciated. 3651. Journal of Chemical Physics ,8, 212. In this article, the effect of commonly used ingredients in muffins (sugar, glycerol, potassium sorbate, acidic agent, salt), with and without ethanol surface spraying and pasteurization on the shelf life, was examined.

Bread adulterated by rope spoilage is rendered inedible and ultimately thrown away.4, The time taken for rope spoilage to become obvious depends on the level of contamination, and the conditions of storage such as temperature and relative humidity. As bread is a very important staple food, its spoilage threatens global food security. American Institute of Baking Research Department, 1, 12.

Detection of rope spoilage in bread caused by Bacillus species. It needs only one spore from a, strain that prevails under the given conditions to t, spoilage. PMC This will prevent condensation and sogginess. Sodium diacetate has been recommended for use in baked goods, bread, candy, cheese spreads, meats, sauces and more, due to its microbial inhibitory action. (1995). Conversion of some bakeries from using the antimicrobial calcium propionate to vinegar has also been suspected of enhancing rope spoilage due to the inefficiency of vinegar in dropping the pH.

The rope spore count of bread of the bread with carambola fruit pomace powder at this level showed a count of 0.7 log10/g, an inhibition equal to that of bread with chemical preservatives added. This almost sounds like rope spoilage. The rank of acidic agents effectiveness in MFSL was citric acid > sodium diacetate > tartaric acid.

Reviews of Environmental Contamination & Toxicology, 127, 6993. (1982) Recent work on bread staling. I noticed today that the muffins had a slimy outside texture and white thin strings on the inside when broken apart, my research tells me it's "rope spoilage" and it's caused by a bacteria. Eliasson, A.C. (1985) Retrogradation of starch as measured by differential scanning calorimetry, in New Approaches to Research on Cereal Carbohydrates (eds R.D. Willhoft, E.M.A. 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.

The preservative used was potassium sorbate (Cheminova) and the acidic agents were citric acid (ADM), tartaric acid (ADM), and sodium diacetate (Borniger). and Tsen, C.C. Journal of Seiler, D.A.L. This behavior of acidic agents could be attributed to the reduction of pH in the range 5.56, where potassium sorbate is more effective. Frederick K. Cook .

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.

In addition, these agents particularly Na diacetate and citric acid are considered mould and rope growth inhibitors. This study was conducted to detect the presence of rope-producing Bacillus spp. 669730. Rope spoilage is a quality defect in bread caused by microbial activity. (Eds. The spoilage organoleptically or by pathogenic microbial growth is relatively small in cakes because of the nature of the ingredients used in cake making. Food Chemistry ,25, 2416. Implementation and enforcement of good manufacturing practices, pre-requisite programs, food safety systems are necessary for reducing the proliferation of rope-causing bacteria. Food Microbiol. Spoilage bacteria can cause fruits and vegetables to get mushy or slimy, or meat to develop a bad odor, but they do not generally make you sick. FMBRA Bulletin No. Clark, H.A. 18, 848853.

Increasing consumer demand for preservative-free products and global warming may increase the occurrence of ropy spoilage. They also decrease starch gelatinization in cakes leading to a better cake structure with improved tenderness. These spores are resistant to heat and can survive baking temperatures and subsequently grow in the finished product under hot and humid conditions.

These preservatives have two functions: (1) to prevent the bacterial spoilage of bread known as `rope' caused by certain Bacillus spp., notably B. subtilis and B. licheniformis, and (2) to retard the rate of mould development.
