The zero-additive compound nutritional fruit and vegetable buccal tablet is very exquisite in raw material selection, for example, the orange juice is obtained by reducing orange concentrated juice, and the orange concentrated juice is prepared by squeezing fresh orange into raw juice and then evaporating a part of water by adopting a low-temperature vacuum concentration method. The orange concentrated juice can furthest retain unique nutritional ingredients and bioactive ingredients in sweet oranges, can improve the concentration, sugar degree and acidity of the juice, inhibit quality deterioration caused by microorganisms, can be preserved for a long time without sterilization or addition of any preservative, is convenient to transport and low in cost, and is a preferred raw material in the orange food industry.

The orange pulp slurry selected by the invention not only contains rich juice, but also mixes the pulp, the capsule coat, the tangerine pith and other parts in the fruit, and the parts contain various useful substances, such as sugar, hemicellulose, cellulose, pectin, glycoside, flavonoid and the like. Wherein, the sugar and the cellulose substances can increase the mouth feel, the pectin substances can play a thickening role, and the flavonoid substances can improve the nutrition and the functional activity, and are one of the very important raw materials in the preparation of the buccal tablet.

The invention adopts the cooked potato pulp to prepare the potato with the skin by cooking and pulping, thereby not only omitting the peeling process, but also keeping rich vitamins, dietary fibers and potassium in the potato skin. Meanwhile, the potato has rich and complete nutrient components, a large amount of starch can provide abundant heat for human bodies, and the content of abundant vitamin C of the potato is far higher than that of food crops; its higher protein and saccharide contents are greatly higher than those of general vegetables. The potato has complete nutrition and reasonable structure, especially the molecular structure of the protein is basically consistent with that of the human body, so that the potato is easy to be absorbed and utilized by the human body, and the absorption and utilization rate is almost up to 100 percent.

Compared with the prior art, the invention has the advantages that:

(1) the invention provides a zero-additive compound nutritional fruit and vegetable buccal tablet, which comprises the following raw material components: 175-240 parts by mass of orange juice, 35-40 parts by mass of orange pulp slurry and 20-30 parts by mass of cooked potato slurry, wherein the cooked potato slurry contains abundant starch, the starch is subjected to gelatinization reaction in the cooking process of the potato, the viscosity of the gelatinized starch is increased rapidly, and the gelatinized starch can be used as an adhesive of the buccal tablet, but the starch in the potato has poor plasticity and cannot achieve the purpose of forming; the orange pulp contains abundant pectin components, the pectin is acidic polysaccharide rich in uronic acid and is low-ester pectin subjected to partial acetylation, and the monosaccharide components of the pectin are galacturonic acid, galactose, arabinose, rhamnose and fucose, and mainly contain type I rhamnogalacturonic acid (RG-I type) structure. The pectin has lower sensitivity to acidity, can better keep the viscosity of the pectin and play a role in thickening, and can meet the requirement of pressing and forming the buccal tablet through the complementation of raw materials by matching with starch in the cooked potato pulp in a proper proportion; the orange juice is rich in fructose, the metabolism speed of the fructose in a human body is slower than that of the traditional sugar such as glucose, sucrose and the like, and the metabolism of the fructose does not depend on insulin, but directly enters the intestinal tract of the human body to be digested and utilized by the human body, so the glycemic index of the fructose is far lower than that of the traditional sugar. However, fructose is more prone to moisture absorption than sucrose and the like, and on the basis of the fact that starch rich in potatoes and fiber components in orange vascular aurantii can obviously reduce the moisture absorption rate, the problem that the buccal tablets are prone to moisture absorption is solved, specifically: pectin in orange pulp slurry and starch in potato cooked slurry are compounded to replace magnesium stearate as an additive, so that the plasticity problem of the buccal tablet is solved; starch rich in the cooked potato pulp and fiber components in orange tangerine pith are used for replacing processing aids such as starch, maltodextrin and the like added in the production process, so that the problem that the buccal tablet is easy to absorb moisture is solved; the taste problem of the buccal tablet is solved by using the abundant fructose component in the orange juice to replace sweetening agents such as sucrose and the like. According to the invention, the advantages of the components of the orange juice, the orange pulp and the cooked potato pulp are utilized, and the proportioning is repeatedly optimized, so that the zero-additive compound nutritional fruit and vegetable buccal tablet which is pure natural, free of additives, good in color and luster, good in taste, rich in nutrition and convenient to eat is obtained, the purposes of buccal tablet compression molding, unique flavor, rich nutrition and the like are realized, the bottleneck that the traditional fruit and vegetable buccal tablet can be compressed and molded only by adding food additives such as an excipient, an anticaking agent, a sweetening agent and the like is broken through, and the high economic value and the good application situation are realized.
