Description

Technical Field

[0001] The invention relates to the technical field of food chemistry, and more particularly to a high-multiple compound plant sweetener and a preparation method thereof. Background Art

[0002] Sweeteners are widely used in the field of food processing and can be classified into natural sweeteners and artificial sweeteners according to their sources. Natural sweeteners such as sucrose and honey are naturally sweet and have no bad taste, but the product has high calories, and long-term drinking can easily cause chronic diseases such as obesity and hyperglycemia, and has no health benefits. Artificially synthesized high-intensity sweeteners have the characteristics of high sweetness multiples, no calories, and non-caries. High-intensity sweeteners can replace part or all of sucrose when used alone or in combination, which can reduce the calories of the product, provide a good taste, and greatly reduce the cost of the product. However, high-intensity sweeteners also have certain defects. When used alone and reaching a certain dosage, the undesirable characteristics of high-intensity sweeteners will be particularly obvious, such as affecting digestive function, causing diarrhea, single effect, poor taste, etc., which limits their application.

[0003] Compound sweeteners can combine the characteristics of various sweeteners, learn from each other's strengths and overcome their weaknesses, and solve the shortcomings of single sweeteners. By compounding sweeteners, the following can be achieved:

[0004] (1) Increase sweetness and reduce costs. The synergistic effect between sweeteners can make their sweetness exceed the sum of the sweetness of several sweeteners, reducing the amount of compound sweeteners used, thereby reducing production costs.

[0005] (2) Increase flavor and reduce unpleasant tastes. When using a single sweetener, there are certain defects. For example, saccharin has a certain bitter aftertaste; sodium cyclamate is relatively cheap but tastes slightly bitter and has poor acid resistance; stevioside has a certain grassy smell; the sweetness of AK sugar is felt quickly but briefly, and it has a slight bitter aftertaste when used alone at high concentrations; and aspartame and neotame lack initial sweetness, and the sweetness is released slowly and lasts for a long time.

[0006] Therefore, it is an urgent problem for technicians in this field to solve how to make up for the deficiency of a single sweetener by scientifically and rationally compounding various sweeteners. Summary of the invention

[0007] In view of the above problems, the present invention provides a high-intensity compound plant sweetener and a preparation method thereof, wherein a safe and healthy pure plant high-intensity sweetener with low energy, low carbohydrates, rich in dietary fiber and protein is prepared by compounding a formula of natural plant sweeteners such as mogroside, licorice extract, steviol glycoside, neohesperidin dihydrochalcone, etc., and having obvious functions of a healthy food.

[0008] One of the purposes of the present invention is to provide a high-multiple compound plant sweetener, wherein the content of each component is as follows based on 100g mass: 0.001-5g of mogroside, 0.001-2g of stevioside, 0.001-5g of licorice extract, 0.0001-2g of neohesperidin dihydrochalcone, 0.01-0.015g of stachyose, 0.005-0.01g of D-isoascorbic acid, and 0.005-0.01g of ascorbic acid, and water-soluble dietary fiber is added to 100g.

[0009] Mogroside: It has good water solubility, has the aroma of mogroside, is 300 times sweeter than sucrose, has zero calories, has the effects of clearing heat, moistening the lungs and relieving cough, moistening the intestines and promoting bowel movements, and has preventive and therapeutic effects on obesity, constipation, diabetes, etc.

[0010] Stevioside: The sweetness is about 200-300 times that of sucrose, with a bitter and grassy aftertaste and low caloric value.

[0011] Licorice extract: a medicinal ingredient extracted from hay, generally containing glycyrrhizin, glycyrrhizic acid, glycyrrhizin, licorice flavonoids, quercetin, formononetin, quercetin, etc. It can be used as a food additive to replace the sweetness of sucrose, and combines aroma, flavor and health care.

[0012] Neohesperidin dihydrochalcone: Its sweetness is 1500-1800 times that of sucrose, it has a refreshing taste and a long-lasting aftertaste, it has an excellent effect in shielding bitterness, and the aftertaste lasts for a long time. The glycoside group does not participate in metabolism, so its caloric value is extremely small, and it has the effects of lowering blood lipids, blood sugar, and protecting the liver.

[0013] Stachyose: A natural tetrasaccharide, it is a functional oligosaccharide that can significantly promote the proliferation of beneficial bacteria such as bifidobacteria. It has a sweetness of 22% of sucrose, a pure taste without any bad taste or odor, and has the effects of regulating intestinal flora, moisturizing the intestines and promoting bowel movements, and lowering blood lipids.

[0014] D-isoascorbic acid: It tastes sour and can be used to adjust the sweetness of compound plant sweeteners.

[0015] Ascorbic acid: an antioxidant that also adds sweetness to compound plant sweeteners.

[0016] Water-soluble dietary fiber: It is sticky and can absorb a large amount of water in the intestines to produce a laxative effect; it can effectively activate the probiotics in the intestines, promote their growth and reproduction, and create a healthy state of the intestines; it can also prevent colon and rectal cancer, prevent and treat hemorrhoids, lower blood lipids, improve the symptoms of diabetes, and the functions of the mouth and teeth.

[0017] The beneficial effects of the above technical solution are as follows: the high-intensity sweetener compounded with plants as raw materials of the present invention has obvious health food functions. For example, the raw material combination and the comprehensive compounding ratio can remove bile acid in the body and have a certain effect of lowering serum cholesterol. Because of its low calorie, stability, high temperature and acid resistance, it can be widely used in various foods, especially low-energy, high-fiber functional foods.

[0018] Furthermore, the high-power compounded plant sweetener of the present invention can be used in the form of aqueous solution, microparticles, granules, or dry solids.

[0019] The second object of the present invention is to provide a method for preparing a high-power compound plant sweetener, comprising the following steps:

[0020] (1) Weigh the raw materials of each component according to the above formula and mix them evenly;

[0021] (2) adding a certain amount of purified water to the mixed raw materials and heating them to 95° C.;

[0022] (3) obtaining a high-multiple compound plant sweetener solution after high-pressure homogenization;

[0023] (4) Spray drying or freeze drying the high-multiple compound plant sweetener solution.

[0024] Preferably, in step (2), the solid-to-liquid ratio of the mixed raw material to pure water is 5%-80%.

[0025] Preferably, in step (3), the high-pressure homogenization pressure is 15 MPa-35 MPa.

[0026] Preferably, in step (4), the spray drying conditions are 125°C-200°C, and the atomizing nozzle pressure of the spray drying tower should be controlled within the range of 1.0-40MPa for spray drying, depending on the output of the equipment, the specific material properties, the drying requirements, and the production efficiency. 95%-98% of the water is evaporated instantly.

[0027] Preferably, after the spray drying, high-multiple compounded plant sweetener particles of 200-300 mesh (0.075-0.048 mm) are obtained.

[0028] Further preferably, in step (4), the freeze drying is to freeze the material into a solid state at -15°C to -60°C, and then sublime the water directly into a gaseous state without passing through a liquid state under a vacuum of 10Pa-30Pa, so that the material is dehydrated to obtain a dry product.

[0029] It can be seen from the above technical solution that, compared with the prior art, the beneficial effects achieved by the present invention are:

[0030] (1) The high-power compounded plant sweetener of the present invention is made of natural plant sweeteners such as mogroside, licorice extract, stevioside, neohesperidin dihydrochalcone, etc., and is a low-calorie sugar.
