This behavior of acidic agents could be attributed to the reduction of pH in the range 5.56, where potassium sorbate is more effective. But you can from our technical newsletter! (1968) Prolonging the shelf-life of cakes. Citric acid CH2(COOH)-COH(COOH)-CH2(COOH) has not been used as a basic antimicrobial agent, however, it has activity against some moulds and bacteria. Bread crumb contaminated with rope-producing Bacillus becomes soft and sticky to touch and in more advanced stages can almost liquify. Cereal Chemistry ,24,231249. 3099067 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.

Baked goods, containing principally flour are greatly affected by ingredients and additives included in a recipe. The heavier the contamination and the warmer the conditions, the faster rope development will be.4. All of the isolates were identified as Bacillus subtilis by biochemical tests, but molecular assays (randomly amplified polymorphic DNA PCR assay, denaturing gradient gel electrophoresis analysis, and sequencing of the V3 region of 16S ribosomal DNA) revealed greater Bacillus species variety in ropy breads. The shelf life was expressed in relation to the corresponding control. Registered in England & Wales No. Andersson, A., Rnner, U., & Granum, P. E. (1995).

Silliker), Academic Press, Orlando, FL, pp. Prevention of growth of approximately 10(4) rope-producing B. subtilis G1 spores per cm(2) on bread slices for more than 15 days was observed when heat-treated cultures of Lactobacillus plantarum E5 and Leuconostoc mesenteroides A27 were added. Coded values 1 to + 1 correspond to 0.1 to 1 g/100 g of flour and starch. The bacteria B. Subtilis and B. mesentericus both occur naturally in the soil and can be easily carried along with agriculture commodities to the next stages of the food supply chain, thus creating cross-contamination and spoilage issues at the manufacturing level. Spoilage organisms are different Bacillus species whose heat-resistant spores survive. I'm no expert, but it seems that the most common cause of rope spoilage is the flour. lace your cooled muffins in the container, on top of paper towels in a single layer.
