UV is a cost-effective and energy-efficient thermal treatment alternative for preventing microbial growth in sugar syrups and sweeteners.
For food and beverage facilities seeking to improve the final product quality of sweetened beverages and meet stringent quality standards, UV (ultraviolet) treatment is an effective and economical solution. UV systems treat all known microorganisms* that lead to the spoilage of liquid sugar, such as yeasts, molds and spores. By preventing microbial growth, the quality of the sugar syrup is maintained, and its shelf-life is extended without the need for chemical additives and preservatives.
Extends shelf life
Reduces product waste
Maintains flavor and product quality
Reduces need for chemical additives or preservatives
UV systems prevent microbial growth in sugar syrups through the UV inactivation process. When microorganisms are exposed to wavelengths of UV light, their DNA is damaged, and they are instantaneously rendered incapable of reproducing.
Many liquids can be effectively treated using UV, including cloudy or darker fluids with a UV Transmittance (UVT) as low as 20%. Our systems are optimized to treat these fluids by forcing the liquid to be exposed closer to the lamps for a longer period of time to receive higher doses of UV energy.
Microbiological inactivation with UV is a physical process that adds nothing to the fluid it is treating but UV light and therefore does not impact taste, odor and color. This is particularly beneficial when treating product water or sugar syrups for beverages. The speed and efficiency of the treatment process allow the footprint of UV systems in syrup rooms to be relatively small, making it ideal for both new plants and retrofits.
Minimal contact time required
No impact to taste, odor, or color
Compact system
Easy to install
For those products that can tolerate the temperature, heat pasteurization may be an option to treat liquid sugar and sugar syrups. Although, thermal treatment has been known to be an energy-intensive process that can lead to the potential formation of possible carcinogens such as Hydroxymethylfurfural (5-HMF). As an alternative, UV can provide some significant benefits:
