Description

GUM BASE COMPOSITION FOR NON-CALORIE LOW DENSITY AERATED GUM AND A METHOD FOR PRODUCING THEREOF

The present invention is related to a non-styrene butadiene rubber gum base composition for non-calorie, non-cariogenic chewing gum with good elastic chewing characteristics and bubble forming properties and a method for producing thereof.

The non styrene butadiene rubber gum base of the present invention shows good miscibility with air bubbles and shows good cohesive strength to keep the air bubbles trapped in the gum during processing and storage.

The gum base in the present invention shows very good flavor perception and with long lasting flavor. The gum base is used in a non calorie, low density gum with a gum base content above 90% where the finished product has pure white color.

Background of the invention

The present invention relates to a non styrene butadiene rubber gum base composition used to prepare non calorie low density products with a density between 0,5 gram/ml to 0,9 gram/ml and a soft and elastic consistency and big bubbles.

The present invention describes gum base composition and method used to manufacture the same.

Prior Art

The present invention relates to a type of gum found in Turkey and some of the surrounding countries in the middle east and the some of the southern states of the former Soviet Union. The gum product consists primarily of gum base and flavor without any sweeteners or softeners and is aerated to improve flexibility and softness.

This is a traditional product in this region of the world. Earlier, people were used to chew a resinous substance called gum mastic that is collected from a special pistachio tree. This has been chewed for centuries to keep the mouth moisturised with saliva when people were working in the fields. This tradition has continued until today and people in general like to chew this type of product .

The local gum industry developed products in accordance with this where the gum is based on a gum base containing only synthetic ingredients including styrene butadiene rubber. This is added very low content of flavor and aerated to create the final gum. In the local market this type of product is called "oriental gum".

The flavors used in this type of product is flavors like gum mastic, rose, clover, and similar flavors. Today there are also more widely known flavors introduced like fruit and mint flavors but the traditional flavors are still widely preferred.

The known products on the market use gum bases which have intense off taste due to the selection of raw materials like Styrene Butadiene Rubber and a lot of low cost rosin esters like glycerol ester of rosin. The typical off taste of this type of gum can be described as bitter, burned or smoked type of flavor.

The gum base of the present invention has proved to have a very low gum base off taste and pure white color in the final product.

The state of the art formulas and the technology have been based on a styrene butadiene rubber as elastomer due to this elastomer gives in a well balanced formula and a homogenous gum base that will allow entrapment of air bubbles into the gum. Until now this has not been possible with the non-styrene butadiene rubber formulas as they are not homogenous. Besides, styrene butadiene rubber formulas have good stretching properties that allow them to be pulled or aerated with air under pressure. This also has not been possible with the non-styrene butadiene rubber formulas as they are not completely homogenous.

Detailed Description of the Invention

The non styrene butadiene rubber formula in the present invention shows good entrapment of air bubbles and shows good stretching properties when pulled and shows good cohesive properties when aerated under pressure.

Chewing gum comprises a water insoluble portion, the gum base, which remains in the oral cavity and a water-soluble portion, which dissolves during chewing. Flavor and sweeteners like sugar, glucose, sorbitol, xylitol or if any are primarily provided by the watersoluble portion while organoleptic properties such as structure, elasticity, film forming capacity, tackiness, softness etc. are usually provided by the gum base portion. To obtain the desired properties in a chewing gum product the gum base is prepared from ingredients selected on the basis of their special organoleptic properties, their workability, their compatibility and their shelf life properties.

The gum base consists of between 8 to 20 different ingredients. These ingredients include raw material groups such as elastomer, resins, fillers, emulsifiers, fats, waxes and antioxidants.

The gum base portion is prepared as a single process or as a 2-step process that may include a preparation of a premix. The selection of these processes will depend on the selection of raw materials used for the gum base. The gum base manufactured in the state of the art is manufactured in a double-jacketed Z blade mixer heated with steam or oil.

The mixing procedure starts with addition of some resin and filler are added to the rubber and mixed thoroughly. After the raw material is absorbed, more filler and resin are added. Mixing is continued until all resin and filler are added. Then, waxes are added slowly to prevent fast melting of too much wax and in order to ensure fast uptake of the liquid wax in the mixture. Later other softeners are added. To provide a homogenous mixture, the blend is mixed 10 to 15 minutes after last addition of raw materials and before the mixing procedure is ended. The gum base is usually taken out of the mixer at a temperature of about 100° C.

When the gum base is manufactured, it is used directly for the manufacture of the non-calorie low-density gum product. This means that flavor can be added to the gum base along with some auxiliary components. As mixed thoroughly and dispersed into the gum base, it is ready for gum production.

Conventionally there are two processes used for the manufacture of this non- calorie low-density gum. The first process is a pulling process and the other process is a continuous process described in WO 98/34497.

The pulling process is a batch process where the molten gum base is cooled in water to a temperature between 30 and 45° C and after cooling, a portion of the cooled gum is introduced to the pulling machine.

The pulling machine has two rotating mixing arms and one stationary arm. The gum is aerated by the mixing arms while being pulled and stretched. During this process air is blocked inside the gum. When the gum is getting almost white and dough like its ready for extrusion. The extruder forms a rope that is cooled in a cooling tunnel and when passed the tunnel the gum is wrapped in a wrapping machine either as single twist or as 5 or 7 piece pack.

According to the process described in WO 98/34497 the gum base is taken out of the mixer without adding any flavor. The gum base is taken out and pumped to a holding tank and pumped from there to the aerator. When the gum base is pumped from the holding tank and passes through a heat exchanger to cool the gum down to a temperature between 45°C and 65°C and after this flavor and maybe a sweetener are injected therein. The gum will then be aerated with air under pressure and mixed in a mixer with both rotating and stationary mixing pins. An almost white gum will now be pumped to the extruder and fomied to a gum rope and cooled in a cooling tunnel and wrapped.

US patent 4.698.223 discloses a chewing gum composition which comprises up to 99% by weight of a completely sugar-free base gum. Such a chewing gum is calorie-free and non-cariogenic. Furthermore it has been found to be substantially non-adhesive to the teeth, particularly to dental prostheses. The gum contains up to 3% flavorings and up to 4% glycerol.

US patent 4.357.354 discloses a reduced calorie chewing gum which does not decrease in viscosity upon chewing and contains less then 65 % water-soluble, such as sugar and/or sugar alcohols such as sweeteners, and includes gum base containing high level of inert fillers, such as calcium carbonate or talc in amounts of at least about 40% by weight, softeners, such as lecithin, and optionally syntetich non-caloric sweeteners, such as aspartame, saccharin, or cyclamates. The chewing gum includes at least about 10% air voids entrapped in the gum base matrix which, upon chewing, become filled with moisture causing dramatic increase in cut volume. EP 414 932 Al discloses a chewing gum composition, which comprises 25 to 90%) by weight of a known gum base. The chewing gum composition exerts its anticariogenic effect both locally and internally, simultaneously assures a preferable condition for fluoride ions to build into the teeth by mechanical and chemical effect, thus less fluoride compound needed and the building-in of fluorine ions is accelerated.
