DESCRIPTION:

BRIEF SUMMARY
BACKGROUND OF THE INVENTION

The invention relates to a polyol composition obtainable by co-spray-drying.
Polyols and polyol mixtures are used to a great extent as additives and carriers, inter alia, for tablets for chewing and sucking, chewing gum and other products of the confectionery industry. The particular advantage of polyols is that they are suitable in principle even for direct compaction without further processing aids and additives. Polyols are generally produced by hydrogenation of their underlying carbohydrates. In solid form, they can be obtained both by crystallization and by spray-drying.
In the production of compacted articles, such polyols generally give a rough, not very satisfactory surface, or, in the case of polyol mixtures, in addition, a low hardness. Therefore, special processes have been developed in order to prepare polyols suitable for improved compaction.
In DE 32 45 170, it is proposed to prepare a polyol combination from sorbitol and 10 to 15% by weight of mannitol by spray-drying. This is intended to increase the flexural strength of tablets. There is no indication there that improved properties, in particular higher plasticity, can be achieved with polyol combinations containing other polyols or relatively low proportions of mannitol and obtainable by spray-drying.
Furthermore, a polyol of this type is less suitable for the production of chewing gum, since these become too hard after a short chewing time.
EP 0 528 604 describes a sorbitol and xylitol composition obtainable by co-melting. However, this leads to tablets having a comparatively low hardness.


SUMMARY OF THE INVENTION

The object was therefore to provide a polyol composition which can be produced without problems and whose tableting properties and plasticity are improved in comparison to known polyols.
It has now been found that a polyol composition obtainable by co-spray-drying comprising less than 10% by weight of mannitol gives a much smoother surface in tableting at the same pressing force and that this product may be processed to give chewing gums which have improved processing properties and remain soft much longer than chewing gum produced with conventional sorbitol or mixtures of sorbitol and other polyols.
The invention therefore relates to a composition essentially obtainable from at least two polyols by co-spray-drying which comprises less than 10% by weight of mannitol.
The term polyol means sugar alcohols of the general formula particular C.sub.12 H.sub.24 O.sub.11.
In particular, the term polyols means hexitols such as sorbitol and mannitol, and pentitols such as xylitol, are possible as well as C.sub.4 -polyhydric alcohols such as erythritol or C.sub.12 -polyhydric alcohols such as lactitol. The term polyol composition means a composition of a plurality of polyols which differ markedly in their composition from compositions arising in the industrial preparation of sorbitol, preferably those compositions which comprise at least two polyols having a different number of C atoms, in particular the term means a composition comprising at least one hexitol and at least one pentitol.
Preferred embodiments are spraying the resulting aqueous mixture in an air stream having a temperature of 120.degree. to 300.degree. C. mannitol are used as polyols. between 50:50 and 99:1, in particular between 65:35 and 98:2. between 90:1:9 or 70:29:1 and 98:1:1, in particular between 90:2:8 or 80:18:2 and 94:1:5 or 94:5:1. storage in a hygrostat at 55% relative humidity.
The invention further relates to compacted articles such as tablets for sucking or chewing and chewing gums, and confectionery comprising a composition of the invention.
The invention further relates to a process for the preparation of a composition essentially consisting of at least two polyols, including the following steps: solution has a mannitol content of less than 10% by weight, based on the total polyol content, temperature between 120.degree. and 300.degree. C., where the water is evaporated, and
In a particularly preferred embodiment, the polyol
