Product description
Potassium sorbate is a salt of sorbic acid which is naturally found in some fruits (like the berries of mountain ash). The commercial ingredient is synthetically produced creating what is termed a “nature identical” chemical (chemically equivalent to the molecule found in nature).
Similar to other sorbates, K-sorbate can:
1. Inhibit microbial growth by changing the cell membrane morphology and integrity. Disrupt the transport functions and metabolic activity.
2 Be more effective than other preservatives, such as calcium propionate and sodium benzoate in inhibiting mold growth in bakery products.
3 Increase the product shelf life with limited impact on food quality. If used at very high concentration, it can have an undesirable effect on taste and flavor.
K-sorbate is typically used in chemically-leavened products (dry blended with the flour) at a level of 0.03% to 0.4% of the batter weight. Because of its deteriorative effect on yeast cells, K-sorbate can reduce loaf volume and generate a sticky dough that is difficult to process, therefore, it is not suitable for bread baking. K-sorbate can also be sprayed onto product surfaces after baking such as the case with tortillas.
