Improved confectionery aroma containing products
The present invention relates to confectionery products comprising an isomalt component, a geraniol containing aroma component and at least one product additive as well as processes to obtain them.
In consideration of the increasing demand of customers for confectionery products, which do not only appeal because of their taste but also because of the functional benefits, more and more innovative confectioneries are developed. Thus, it is desired to develop confectionery products, which do not only provide a good taste but exert furthermore an additional effect.
Recently, it has been described that distinct aromatic compounds are exhalated from human skin after intake of essential oil. The oral intake of essential oil with water resulted in an augmented release from geraniol and citronellol which were detected from hand skin us- ing gas chromatograph mass spectrometry (Akiyama, Asaku and Itoh, Kenji, Aroma Research (2006), Vol. 7(1), 63-65). Further, the oral intake of rose oil resulted in the detection of linalool, citronellol and especially of geraniol, which are the main components of rose essential oil, from the skin (Akiyma, Asaku et al., Bunseki Kagaku (2006), 55 (10), 787-792 - 792).
Geraniol, also called rhodinol, is a monoterpenoid and an alcohol. It is the primary part of oil-of-rose, palmarosa oil and citronella oil. It also occurs in small quantities in geranium, lemon and many other essential oils. It appears as a clear to pale-yellow oil, which is insolu- ble in water, but soluble in most common organic solvents. It has a rose-like odour, for which it is commonly used in perfumes. Further-
more, research has shown geraniol to be an effective plant based insect repellent.
The technical problem underlying the present invention is to provide confectionery products, which not only fulfil organoleptical demands of the consumer, but further harbour at least one further additional beneficial effect which increases the consumers' acceptance. In particular, it is desired to provide confectionery products which show an improved, in particular more constant and continuous release of aroma, namely geraniol and preferably are particularly storage- stable.
The present invention solves the underlying technical problem by the provision of a confectionery product, which comprises an isomalt component, a geraniol containing aroma component and at least one product additive.
Thus, the present invention solves the above-identified technical problem by providing a confectionery product comprising a mixture of an isomalt component, a geraniol containing aroma component and at least one product additive, wherein the confectionery product comprises 1.0 to 99.8 weight-% of the isomalt component, 0.1 to 5.0 weight-%, preferably 0.2 to 4.0 weight-%, most preferably 0.5 to 2.0 weight-% of the geraniol containing aroma component and 0.1 to 98.0 weight-% of at least one product additive (each based on total weight of confectionery product and all constituents adding up to 100.0% of dry matter of the confectionery product). The combination of the isomalt component with the geraniol containing aroma component surprisingly leads in confectionery products, in particular in chewing gums, coated chewing gums, soft caramels, tablets and
hard caramels, to a very favourable aroma release profile, in particular a continuous, long lasting and constant release and exhalation from the skin of the consumer which in addition very rapidly starts after consumption of the product. Furthermore, it could be shown that the isomalt component increases the storage stability of the aroma component in the confectionery product.
The exhalation of geraniol leads to a pleasant rose-like odour which is released from the skin of the consumer after consumption of the confectionery product. It could surprisingly be shown that the combi- nation of an isomalt component together with a geraniol containing aroma component advantageously leads to an even elevated, more constant and continuous exhalation of the geraniol from the skin of the consumer compared to the intake of a geraniol containing aroma component alone without the isomalt component. Without being bound to any theory, it is assumed that the elevated exhalation is a result of a more effective uptake after consumption of the geraniol due to the combination with isomalt. This in turn leads to an early beginning, elevated, prolonged and promoted release of the geraniol from the consumers' skin. Thus, the isomalt component acts as an odour release elevator. Furthermore, it has been shown that the isomalt component within the confectionery product of the present invention has the advantage to mask the unpleasant taste of the geraniol. As a further advantage it could be shown that despite its low water solubility the geraniol containing aroma component exhibits in combination with the isomalt component a homogenous distribution, especially when used in hard caramels. In chewing gums and soft candies an improved, in particular longer lasting chewability was observed.

The applied coating layers are dried after each cycle with a constant air stream with a temperature ranging from 23 to 28°C. Afterwards, the geraniol oil is added to the coating solution and the coating solution is applied in a fourth phase in 5 cycles, in a fifth phase in 5 cycles and in a sixth phase in 3 cycles. The applied coating layers are dried after each cycle with a constant air stream. Thus, in overall, a coated product is prepared comprising 33 weight-% coating and about 67 weight-% (each based on dry weight of final product) chewing gum centre.
A coated chewing gum was obtained with favourable organoleptic and sensoric properties, which provides a constant and continuously released pleasant rose-like odour by exhalation from the skin. The coating showed a very good storage stability.
