Abstract

PURPOSE:To prepare a chewing gum of high quality in easy steps, by dipping mixed whole raw materials for the chewing gum in liquid nitrogen, pulverizing and uniformly mixing the cold raw materials at the same time, returning the raw materials to ordinary temperature, and if necessary molding the resultant materials into a given shape. CONSTITUTION:The whole raw materials for a chewing gum are introduced into a freezing hopper of a freeze crushing apparatus in irregular order. In the process, lumps, e.g. a resin or rubber, are previously cut to 5-10mm. size to facilitate the passage through the outlet of the raw material hopper, and other materials are directly used in the usual distribution forms. The whole materials are then dipped in liquid nitrogen, exposed to -196 deg.C cryogenic temperature and cooled to increase the brittleness. Thus, the resin or gum is easily pulverized. The whole raw materials are then fed to a pulverizer and pulverized in a very short time to give a fine powdery uniform mixture, which is then collected in a cyclone, taken out one after another and returned to ordinary temperature not to absorb moisture. The resultant powdery chewing gum is then compression molded in a given mold under a given pressure if necessary to give a sheet chewing gum.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing chewing gum by freeze-pulverization, and more particularly, the present invention relates to a method for producing chewing gum by freeze-pulverization, and more specifically, the production of chewing gum by mixing and pulverizing all raw materials of stewing gum in one step by cryogenic cooling with liquid nitrogen. It concerns the manufacturing method. ′
□ Traditionally, in the seventh step of manufacturing chewing gum, raw materials for chewing gum paste, mainly consisting of natural resins, vinyl acetate resin, synthetic rubber, ester gum, emulsifiers, waxes, and fillers, are put into an open kneader. 3~q hours%
A chewing gum paste is produced by heating and melting at 10 to 10°C, and in the λth step, pre-pulverized sugar, glucose, starch syrup, coloring, and flavor are sequentially added to the chewing gum paste in an open mixer for 30 minutes. A chewing gum mass was obtained by kneading at ~40°C for about 30 minutes, and in the third step, the chewing gum mass was cut and extruded using an extruder, and formed into a chewing gum sheet using multistage rolls.

By the way, recently, freeze-grinding using liquid nitrogen has been put into practical use and has attracted attention in the food industry, with reports of its application to spices and the like. No known examples.

On the other hand, several attempts to cool and crush chewing gum have been reported. For example, d1 A method of cooling and crushing chewing gum paste produced by a conventional method with dry ice, mixing powdered sugar mixed with penicillin, streptomycin, etc. with the resulting powdered chewing gum base, and compressing into tablets (Japanese Patent Publication No. 1-1731) No. Publication/) 1 A chewing gum base produced by a normal method is mixed with chewing gum additive raw materials such as sugar and glucose and then kneaded at -73℃ or lower 5 For example, a liquefied gas refrigerant such as liquid carbon dioxide or liquid nitrogen is injected. A method of obtaining chewing gum powder, which is then crushed under cooling to obtain chewing gum powder, which is then subjected to certain processing to obtain chewing gum confectionery that is light, soft, and has a good texture (Unexamined Japanese Patent Publication H.
io-iyjzto public v &) there is natote.

That is, the object of these inventions was to cold-pulverize or freeze-pulverize a chewing gum base or chewing gum that is difficult to crush to obtain a powdered chewing gum, thereby obtaining a tablet chewing gum or a chewing gum with a good texture5.

However, the object of the present invention is to modify the chewing gum production method of the three factories mentioned above, and to improve the recently developed process of the first step of producing a chewing gum base and the second step of obtaining a chewing gum mixture. The resulting chewing gum powder is
An example is compression molding to obtain a chewing gum sheet, which provides a completely new chewing gum production system.

Furthermore, another object of the present invention is to provide a chewing gum manufacturing system that does not require a heating step.

In order to achieve the above object, one aspect of the present invention is as follows.

All the raw materials for chewing gum are mixed, immersed in liquid nitrogen and cooled, and mixed uniformly at the same time as pulverized at low temperatures.The resulting pulverized product is returned to room temperature and molded into a predetermined shape as necessary. Features.

The types and amounts of raw materials for chewing gum used in the present invention are the same as in conventional chewing gum manufacturing methods. In other words, the main raw materials for chewing gum base include natural resins such as chicle resin, synthetic resins such as vinyl acetate resin,
Synthetic rubbers such as polyisobutylene and polybutene, emulsifiers such as monoglycerides, fillers such as talc and calcium carbonate, and ester gums, etc. The main raw materials for chewing gum additives include natural sweeteners such as sugar, glucose, and starch syrup. These include artificial sweeteners, acidulants such as citric acid, flavorings, and coloring agents. The amounts of these raw materials can be used on the same basis as in conventional chewing gum manufacturing methods.

On the other hand, the way raw materials are used differs from conventional chewing gum manufacturing methods. In other words, in the past, sugar, glucose, citric acid, etc. had to be ground into fine powder before use.
In the production method of the present invention, preliminary pulverization is required, and the product can be used in its original distribution form. The lumps of resins, rubbers, etc. are cut into J-10IIjl pieces in advance so that they can easily pass through the raw material hopper outlet. Other raw materials are used in solid, liquid, or viscous form in their normal distribution form.

All prepared raw materials for one unit of chewing gum are placed in random order into the freezing hopper of the freeze-pulverizer.

Next, liquid nitrogen is introduced into the freezing hopper and all the raw materials for chewing gum are submerged and cooled in liquid nitrogen. As a result of this cooling, the material is exposed to an extremely low temperature of approximately -1 ytη and is cooled, increasing its brittleness and changing into a state in which resins and rubbers, which are considered to be difficult to crush, can be crushed very easily.

Next, all the raw materials are fed to a crusher by means of a screw tweeter, and after several hours of crushing operation, a finely divided and uniformly mixed chewing gum powder is obtained. The grinding process is also controlled so that the temperature rise due to grinding does not exceed a specified temperature by cooling the material. In the case of chewing gum, it is applied while maintaining the product temperature at -20°C or lower, preferably Id, or -110°C or higher. The finer the particle size, the better, but 10
Grind to 0 mesh or less, preferably /, j O mesh or less.

The nayuing gum powder that has reached a predetermined particle size is collected in a cyclone and sequentially taken out from the cyclone.

The chewing gum powder taken out is returned to room temperature without absorbing moisture. The obtained chewing gum powder is compression-molded at a predetermined pressure in a predetermined chamber to form a sheet gum, if necessary.

Next, the method of the present invention will be specifically explained using Examples and Comparative Examples.

Example/ This example shows an example of manufacturing a gum board. The total amount/KP of the various raw materials in the proportions shown in Table 1 was introduced into the 7-rearing hopper of the freeze-grinding apparatus at approximately the same time. Raw materials are available on the market.
It was used after being crushed to a size of 10m of natural resin wire.

Next, liquid nitrogen was introduced into the freezing hopper to immerse and cool the raw material, and the cooled raw material was introduced into the pulverizer through the hopper outlet via a conveyor. The crusher is also cooled with liquid nitrogen. The pulverization took about 3 minutes, and a chewing gum powder pulverized to less than a TO mesh was obtained in the Lycron. The product was ground at a temperature of -60°C. The mixture was naturally warmed in a closed container to prevent moisture absorption and returned to room temperature. The chewing gum powder that had been brought back to room temperature was put into a sheet gum mold and compressed to obtain a sheet gum troy. Conventional I to correspond.

The raw material ratios used were as shown in Table 1, and the sugar and glucose in the raw materials were previously pulverized using a pulverizer.

Production of gum base: Natural resin, polyisopterene, and vinyl acetate resin were placed in a preheated maple kneader and mixed, kneaded, and dissolved.

Thereafter, ester gum, micro socks, monoglyceride, and calcium carbonate were sequentially added and kneaded until all the raw materials were homogenized. ff1 hour time amount, product temperature/1
The temperature was 0~/-0°C. Preparation f! tlri/Kp.

Manufacture of sheet gum: Gum paste and starch syrup obtained above,
Glucose and half of the sugar were put into a mixer and mixed and kneaded, and after checking the mixing state, the remaining amount of sand and glycerin were added and kneaded until homogenized. Finally, the flavor was added and kneading continued for 1 minute before being removed. The time required was approximately 10-1J minutes, and the temperature was 5o-to-C.

The amount of preparation was /KP.

Forming of gum sheet: The chewing gum mass was extruded into a strip using an extruder and passed through three rolling rolls to obtain a gum sheet.

Comparative test of Example 1 and Comparative Example: Quality test Example 1 and Comparative Example were each repeated j times to produce samples, and two samples were sampled at different locations within the batch during each batch process. Quality tests were conducted on the samples by composition analysis and sensory analysis. The results are shown in Table 2.
Table 3 shows that Example 1 has less variation than Comparative Example 1, although it is slightly smaller.

Table 3 shows that Example 1 produced by the method of the present invention has better elasticity, and the difference in rise is due to the difference in burnt odor. In the case of the comparative example using the conventional manufacturing method, the burnt smell was caused by 1 hour at 1 crystal temperature/10-/20°C during gum base production.
This is due to the harsh processing conditions. Overall, it has been shown that the chewing gum produced by the method of the present invention has superior properties.

Example This example shows the production of bubble gum.

Bubble gum was obtained by carrying out exactly the same treatment as in Example/ for all [/KP] using the proportions of the various raw materials shown in Table 1.

Consumed liquid powder is 1. Comparative Example 2 In this comparative example, bubble gum was produced using a conventional method in accordance with Example 2, and the ratio of raw materials used was as shown in the table below. Bubble gum was obtained by doing exactly the same process as Hee Jae.

Comparative test between Example 1 and Comparative Example: Sensory analysis was conducted using the same comparative test as in Example 1. The results are shown in Table 5.

From Table 1, it can be seen that Example 1 according to the method of the present invention gives better results because the polymer resin that provides the film thickness is not degraded. In addition, it can be seen that the flavor is more clear in Example 1.
