Natural Preservative for Citrus Flavors

Vitiva, Slovenia, introduces a new, natural citrus-flavor protection formula of its INOLENS® rosemary extract line. INOLENS offers full protection of citrus flavors and citrus flavored-food and beverage applications in an all-natural format.

Citrus flavors, citrus essential oils, citrus-oil derivatives and complex citrus components such as citral and d-limonene are highly susceptible to oxidative stress, oxidative degradation and cyclization reaction and outcome, leading to a loss of fresh citrus flavor. Such oxidation factors lead to dramatic change in a product’s organoleptic characteristics, and consequently a decrease in product shelf life.

"Currently, producers use synthetic antioxidants such as BHA and BHT to preserve citrus flavors, but these provide inadequate oxidative protection, insufficient shelf-life protection and don’t allow for a clean label," says Ohad Cohen, CEO of Vitiva. "Market trends imply demand for natural beverages continues to rise, and you cannot use synthetic antioxidants in natural beverages."

Vitiva researchers conducted extensive tests — including sensory protocols — in its application lab to evaluate protection effectiveness of INOLENS® at minimum dosage. The results showed that even 20ppm provides up to six-fold protection for various citrus flavors in comparison to materials protected with BHT. INOLENS® does not alter taste, odor or color of citrus flavors or citrus-flavored food and beverage formulations. INOLENS is easy to handle and dose, has excellent solubility in oil-based media or emulsions and is classified as “natural flavor” by European Council directive 88/388/EEC.

Vitiva is a dynamic, fast-growing nutraceuticals company specializing in developing advanced, application-specific formulations based on natural extracts for protecting various food and cosmetic products against rancidity and oxidative degradation. Its extensive product line includes: AquaRox®, VivOX® and SyneROX®. In addition, a full range of reduced-odor rosemary extracts, INOLENS®, is available in a wide range of concentrations. These pure extracts are soluble in oil or water and available in powder and liquid forms.
