Description

Technical Field

[0001] The invention relates to the technical field of functional foods, and in particular to a composition, a hawthorn and dandelion microbubble tablet and a preparation method thereof. Background Art

[0002] With the accelerated pace of modern life, various factors such as poor oral hygiene habits and living habits have led to a high incidence of oral micro-injuries. According to research, bleeding gums and bad breath are the most common oral problems.

[0003] At present, oral micro-damage repair products are increasingly abundant, including electric toothbrushes, toothpaste, water flossers, oral cleaning tools, mouthwashes, oral fresheners and tooth powders, etc. Among them, the micro-effervescent tablets in oral fresheners are popular among consumers due to their unique dosage form and rich experience. For example, Chinese patent application CN 109303334B discloses an oral micro-effervescent tablet and a preparation method thereof, which includes nutrients, sugar alcohols, acid sources, alkali sources, magnesium stearate, flavors and sweeteners; sugar alcohols are one or a combination of lactose, maltitol, sorbitol, isomalt, mannitol, and erythritol; sweeteners are one or a combination of sucralose, aspartame, stevioside, fructose, white sugar, and mogroside. This invention adds appropriate amounts of acid, alkali, sweeteners and flavors to nutrients, which, under the action of saliva in the mouth, produce micro-effervescence, good taste and strong experience. At the same time, this invented product solves the problem of serious moisture absorption of effervescent tablets during the production process or accelerated testing, and has a certain effect of freshening breath. However, it cannot completely solve the problem of oral sub-health and has certain application limitations.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0005] The purpose of the present invention is to provide a composition, a hawthorn dandelion microbubble tablet and a preparation method thereof. The composition provided by the embodiment of the present invention can safely and effectively alleviate oral sub-health problems, and has a good taste and a good experience.

[0006] The present invention is achieved in that:

[0007] In a first aspect, the present invention provides a composition capable of improving oral sub-health, wherein the active raw materials forming the composition include, by weight, 10-20 parts of hawthorn malt powder, 1-5 parts of dandelion and 3-8 parts of postbiotics; wherein the hawthorn malt powder consists of hawthorn, tangerine peel and roasted malt.

[0008] In an optional embodiment, the mass ratio of the hawthorn, the tangerine peel and the roasted malt is 1:1.2-1.8:0.15-0.25.

[0009] In an alternative embodiment, the postbiotic comprises at least one of Lactobacillus plantarum L-137, Probio-MT and Lactobacillus crispatus KT-11.

[0010] In a second aspect, the present invention provides a hawthorn and dandelion microbubble tablet, the raw materials of which include the composition capable of improving oral sub-health as described in any one of the aforementioned embodiments.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the technical scheme in the embodiments of the present invention will be described clearly and completely below. If the specific conditions are not specified in the embodiments, they are carried out according to conventional conditions or conditions recommended by the manufacturer. If the manufacturer of the reagents or instruments used is not specified, they are all conventional products that can be purchased commercially.

[0025] The embodiment of the present invention provides a composition capable of improving oral sub-health. The active raw materials forming the composition include 10-20 parts of hawthorn malt powder, 1-5 parts of dandelion and 3-8 parts of postbiotics, based on weight.

[0026] The composition capable of improving oral sub-health provided by the embodiment of the present invention adopts a reasonable combination of hawthorn, tangerine peel and fried malt, wherein hawthorn can help digestion and invigorate the stomach, and is used for meat stagnation and stomach distension; fried malt can promote qi and digestion, invigorate the spleen and stimulate the appetite, and is used for indigestion and abdominal distension; tangerine peel can regulate qi and invigorate the spleen, and is used for abdominal distension, anorexia and vomiting and diarrhea. The hawthorn malt powder has good effects of invigorating the stomach and digestion; dandelion has bitter, sweet and cold properties, enters the liver and stomach meridians, has the effects of clearing away heat and detoxifying and anti-inflammatory, and has good effects on alleviating oral halitosis and gum health. In addition, postbiotics - oral inactivated probiotics are added in the embodiments of the present invention, which can increase the antibacterial ability of the human oral cavity on the one hand, specifically by increasing the expression of human defensin-2 (HBD-2) in the muscle epithelial cells of the teeth, thereby enhancing the antibacterial ability of the oral cavity; on the other hand, they can enhance the immune response of the human oral cavity, specifically by the antibodies (IgG and specific antibodies IgG) in the plasma being transmitted to the gingival sulcus through the capillaries, thereby promoting the secretion of IgA in saliva, inhibiting the excessive reproduction of bacteria, and enhancing local immunity of the oral cavity.

[0027] Among them, the hawthorn malt powder is composed of hawthorn, tangerine peel and fried malt. Specifically, the hawthorn malt powder is obtained by hot water extraction of hawthorn, tangerine peel and fried malt and spray drying, and the mass ratio of the hawthorn, the tangerine peel and the fried malt is 1:1.2-1.8:0.15-0.25. For example, the mass ratio is 1:1.2:0.25; 1:1.5:0.2; 1:1.8:0.25; 1:1.2:0.15 and 1:1.3:0.18, etc., and the preferred mass ratio is 1:1.5:0.2. The hawthorn malt powder composed of hawthorn, tangerine peel and fried malt provided by the embodiment of the present invention has a good effect of strengthening the stomach and digestion, and reduces the formation of bad breath.

[0028] Further, the postbiotics include at least one of Lactobacillus plantarum L-137, Probio-MT and Lactobacillus crispatus KT-11.

The amount of dandelion is any value between 1-5%, such as 1%, 2%, 3%, 4%, and 5%. The amount of diluent is any value between 40-50%, such as 40%, 41%, 42%, 43%, 44%, 45%, 46%, 47%, 48%, 49%, and 50%. The amount of acid source disintegrant is any value between 15-25%, such as 15%, 16%, 17%, 18%, 19%, 20%, 21%, 22%, 23%, 24%, and 25%. The amount of alkaline source disintegrant is any value between 10-20%, such as 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19% and 2%. The amount of lubricant is any value between 1-4%, such as 1%, 2%, 3% and 4%. The amount of sweetener is any value between 0.1-1.0%, such as 0.1%, 0.2%, 0.3%, 0.4%, 0.5%, 0.6%, 0.7%, 0.8%, 0.9% and 1.0%. The amount of flavor is any value between 1-5%, such as 1%, 2%, 3%, 4% and 5%. The amount of postbiotics is any value between 3-8%, such as 3%, 4%, 5%, 6%, 7% and 8%.
