[vc_row][vc_column][vc_column_text uncode_shortcode_id=\u00a0\u00bb194560″]At <\/span>Concentrol<\/span><\/a> we innovate with chemistry to have a positive impact on society and the planet. One of our key areas of expertise is the <\/span>cheese industry<\/span><\/a>. Through our Food Processing Aids product line, we draw upon our extensive experience in developing chemical solutions for the food sector. Our offerings include surface treatments for cheeses, ensuring ideal packaging and transportation, along with auxiliary products for food safety and hygiene.<\/span><\/p>\n

In the following article, we will delve into the selection of preservatives for cheese coatings, the relevant regulatory framework, and other crucial considerations.<\/span><\/p>\n

A significant challenge within the food industry, especially in cheese production, is the <\/span>unwanted growth of molds and yeasts<\/b>.<\/span><\/p>\n

Cheeses undergo a curing process, that is, maturation over time. During this process,\u00a0 various microorganisms from the environment and cheese surface can proliferate, potentially affecting and colonizing parts or even the entire surface of the cheese.<\/span><\/p>\n

In Europe and America, food regulations dictate which preservatives are permitted and establish usage limits. Unauthorized preservatives or active ingredients must undergo evaluation and approval by food authorities before use.<\/span><\/p>\n

EU Regulation No. 1333\/2008<\/b> is the reference framework in the European Union on food additives and their uses:<\/span><\/p>\n

\"\"<\/p>\n

Among the different foods detailed in the regulations, cheeses and their subcategories are detailed in point 01.7.<\/span><\/p>\n

\"\"<\/p>\n

Cured cheeses are included in section 01.7.2<\/span><\/p>\n

The edible cheese rind section is included in food category 0.1.7.3<\/span><\/p>\n

From the list in the table above, the only preservatives currently allowed are <\/span>natamycin<\/b> (E-235), <\/span>sorbates<\/b> (E-200, E-202), and <\/span>propionates<\/b> (E-280, E-281, E-282). Natamycin is the most used preservative, since it has no effect against bacteria and is very effective against most types of mold and yeast.<\/span><\/p>\n

\"\"<\/p>\n

Propionates are used in combination with natamycin in some cases because they have very low efficacies on their own.<\/span><\/p>\n

\"\"<\/p>\n

Recent studies have revealed that natamycin’s limited solubility in water, approximately 40 ppm, is the key determinant of its effectiveness as a preservative. Natamycin only exerts its preservative action when it is in its soluble phase, so concentrations exceeding 40 ppm hardly improve its efficacy.<\/span><\/p>\n

As an alternative to the aforementioned preservatives, investigations have explored the use of other food additives, including lactic acid and acetic acid. While these additives exhibit some preservative capabilities, their effectiveness in the context of cheese\u00a0 is limited and remains unproven, even when used in combination with traditional preservatives.<\/span><\/p>\n

Selecting the right preservatives to prevent the growth of molds and other microorganisms is a complex undertaking.<\/span><\/p>\n
