Description

TECHNICAL FIELD

[0001] The present application relates to the field of candies, in particular to a throat moistening chewing candy and a preparation method thereof. BACKGROUND

[0002] Tobacco contains tar, and if a person smokes for a long time, the volatile tar in tobacco is easy to deposit on the surface of teeth to form tobacco stains, causing the teeth to turn yellow. Based on this, the related technology has developed a throat moistening chewing candy for smokers to eat after smoking, which can achieve the purpose of freshening breath on the one hand, and can adhere and transfer the tar stains on the teeth to the chewing candy on the other hand, so as to solve the problem of yellowing teeth of smokers.

[0003] However, the above-mentioned throat moistening chewing candy is only suitable for removing newly formed non-persistent tobacco stains, and the removal effect of persistent tobacco stains formed on the teeth of long-term smokers is not ideal. SUMMARY

[0004] In order to improve the problem that the throat moistening chewing candy in the related art is difficult to effectively remove the persistent tobacco stains formed on the teeth, the present application provides a throat moistening chewing candy and a preparation method thereof.

[0005] In a first aspect, the present application provides a throat moistening chewing candy using the following technical solution:

[0006] A throat moistening chewing candy, comprising a rubber gum base, a sugar alcohol sweetener, a modified filler and a breath freshener; wherein the preparation method of the modified filler comprises the following steps:

[0007] 3.5-4.2 parts by weight of water-soluble gum base is put into 30-40 parts by weight of water, after the water-soluble gum base is fully swollen, 25-30 parts by weight of filler and 4-4.5 parts by weight of rosin glyceride are added, and stirred until uniformly mixed, then poured into a mold and dried to obtain a pre-modified filler; the pre-modified filler is immersed in a mixed aqueous solution of lemon juice and liquorice extract, and after swelling for 5-10 minutes, it is taken out and naturally dried to obtain a modified filler.

[0008] The main difference between the throat moistening chewing candy of the present application and the chewing candy of the prior art is that the filler in the present application is modified. In the present application, the water-soluble gum base, rosin glyceride, lemon juice and liquorice extract are used together to modify the filler. Under the action of the water-soluble gum base, rosin glyceride, lemon juice and liquorice extract, the modified filler can remove persistent tobacco stains from the teeth, and at the same time, will not damage the surface structure of the teeth. In addition, the sugar alcohol sweetener is used to provide a sweet taste source, which can not only improve the flavor of the throat moistening chewing candy to meet the taste buds of the public, but also will not increase the weight burden. The breath freshener can be a breath freshener containing menthol substances, which can give the chewing candy a fresh and throat moistening feeling.

[0009] In some specific embodiments, the mass percentage of the lemon juice in the mixed aqueous solution of the lemon juice and the liquorice extract is 8-10%, and the mass percentage of the liquorice extract is 3-5%.

[0010] The solubility of the liquorice extract in water is limited, and controlling the mass percentage of the liquorice extract to be 3-5% is beneficial to the full dissolution of the liquorice extract, and at the same time, improves the effect of removing the tobacco stains of the throat moistening chewing gum. In addition, controlling the mass percentage of the lemon juice to be 8-10% has the protection effect on the teeth, and at the same time, ensures the effect of removing the tobacco stains of the throat moistening chewing gum.

[0015] In some specific embodiments, the rubber base adopts at least one of natural rubber, styrene-butadiene rubber, butyl rubber and polyisobutylene.

[0016] In some specific embodiments, the sugar alcohol sweetener adopts at least one of sorbitol, mannitol, isomaltitol, xylitol and maltitol.

[0017] Sorbitol, mannitol, isomaltitol, xylitol and maltitol have the effects of low heat and anti-caries.

[0018] In some specific embodiments, the filler adopts nano-silicon dioxide.

[0019] In the chewing process, the nano-silicon dioxide rubs against the teeth to scrape off the tobacco stains on the teeth. The use of nano-silicon dioxide is beneficial to protecting the teeth and preventing the surface of the teeth from being scratched.

[0020] In some specific embodiments, the breath freshener comprises menthol.

[0021] Menthol can effectively cover and neutralize the odor in the mouth, and can bring a strong cooling sensation, helping to refresh the mind.

[0022] In some specific embodiments, the water-soluble gum base uses at least one of gum arabic, pectin, carboxymethyl cellulose, trehalose gum, guar gum, xanthan gum, and carrageenan.

[0023] In a second aspect, the application provides a preparation method of throat moistening chewing candy, which adopts the following technical scheme:

[0024] A preparation method of throat moistening chewing candy, comprising the following steps:

[0025] Dissolve the sugar alcohol sweetener in water to obtain a sugar alcohol sweetener solution;

[0026] After the rubber gum base is melted, the sugar alcohol sweetener solution is added, stirred until uniform, and then the modified

[0027] Filler and breath freshener are added and stirred uniformly, then cooled and shaped to obtain the throat moistening chewing candy.

[0028] In the application, the throat moistening chewing candy prepared by the above method can remove stubborn tobacco stains on the surface of teeth, and has low heat, so that the consumer will not have a weight burden.

[0029] In summary, the application at least includes the following technical effects:

[0030] (1) The water-soluble gum base, gum rosin glyceride, lemon juice, and licorice extract are used together to modify the filler. Under the action of the water-soluble gum base, gum rosin glyceride, lemon juice, and licorice extract, the modified filler can remove stubborn tobacco stains from the teeth, and will not damage the surface structure of the teeth. In addition, the sugar alcohol sweetener provides a sweet source, which can improve the flavor of the throat moistening chewing candy to meet the taste buds of the public, and will not increase the weight burden. The breath freshener can be a breath freshener containing menthol, which can impart a refreshing and throat moistening sensation to the chewing candy.

[0031] (2) In the application, the weight ratio of the rubber gum base, the sugar alcohol sweetener, the modified filler, and the breath freshener is controlled in the range of (8-10):(55-60):(24-25):(1.6-2.2), which is beneficial to further improve the effect of removing tobacco stains of the throat moistening chewing candy.
