The Journal of General Physiology. As bread is a very important staple food, its spoilage threatens global food security. Figure 5 Shelf life of muffins containing potassium sorbate as preservative with different methods. The signs are generally positive, which means that the increase of any of these factors causes positive effect, leading eventually to an increase of the MFSL. It is said to have a preservative effect disproportionately large for its content of acetate. Cumulative total numbers of rope-spoiled, Cumulative total numbers of rope-spoiled breads during storage at 23 and 30C. So, closer values of coefficients of almost all the factors involved (sugar, glycerol, potassium sorbate, acidic agent) and of the optimization parameters in the models (comparison of the parameter y2 with y3 ) were observed. These spores are resistant to heat and can survive baking temperatures and subsequently grow in the finished product under hot and humid conditions.

CRC Critical Reviews of Food Science and Nutrition ,15, 148. Rope spoilage is a bread disease which consists in bacterial decomposition of the bread crumb. So I baked some muffins on Sunday using a box pancake mix and recipe on the box, to try it out. Then, they were cooled for 60 minutes at ambient temperature, removed from the baking pan, wrapped in plastic films, thermo sealed, and stored at room temperature. Rope spoilage is characterized by bread crumb discoloration and a sweet fruit odor that resembles ripe melon or pineapple. FAO Agricultural Services Bulletin. Unauthorized use of these marks is strictly prohibited. Nevertheless, microbiological spoilage of these products occurs, resulting in substantial economic losses. Since the spores are activated when, coming into contact with water at higher temperatures, the, soaker doughs should be cooled down and processed as, quickly as possible.

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. SPECIAL. This fact does not mean that some of the selected factors had no effect on the pH, but the models were very complicated due to the number of interactions (57 interactions). International Journal of Food Microbiology, 36, 129.

The approved best recipe composition was investigated further (in higher degree experimental designs, by spraying the muffins with ethanol (0.51.5 g/100 g of muffin) and by applying spraying with ethanol and pasteurization simultaneously. I can't get a good photo of it but my mother made brownies and I offended her by suspecting rope spoilage when I pulled one of the pieces apart and it had many, many thin white strands between the pieces when it was pulled apart. (1991) A mechanism of bread firming. Hoseney, R.C, Lineback, D.R. It's a key indicator in the food and chemical industries influencing many aspects of processing, shelf life and overall quality.

Ropy bread spoilage manifests in sticky and stringy degradation of the crumb, slime formation, discoloration, and an odor reminiscent of rotting fruit. 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. The results indicated that breads analysed harboured Bacillus species which can be responsible for rope spoilage of bread or food poisoning in humans. Epub 2012 Apr 14.

Trends in Food Science and Technology ,4, 13438. 1, when the rest factors are fixed at their maximum level. Control shelf life 8.3 days. Since the models are not linear, the relationship between the relative mould-free shelf life and the factors involved is more complicated, indicating that muffin MFSL is affected not only by the single factors but also by their interactions.

[Citation7,Citation8] Salt could affect significantly the Mould Free Shelf Life (MFSL), due to its powerful water-binding properties. Rope spoilage or disease is caused by several strains of spore-forming Bacilli. As the leg opening on a pair of raw denim jeans is being fed through the sewing machine during hemming, an uneven amount of tension is placed on the fabric. When cut surfaces of the loaf are slowly pulled apart, thin strands or ropes can be seen stretching from one surface to the other. Cereal Chemistry ,24,231249.
