Description

Technical Field

[0001] The invention relates to the technical field of frozen drinks, and in particular to a frozen drink containing dendrobium officinale and serving as both a medicine and a food, and a preparation method thereof. Background Art

[0002] At present, most of the research on the series of medicine and food combinations is only in the basic theoretical research. The exploration of the nutritional components, pharmacological effects, and health benefits of medicine and food foods is not in-depth, and there are very few that can be effectively transformed into products. There are few categories of medicine and food application products close to daily life, lack of innovation, and many foods have bitter and sour tastes due to traditional Chinese medicine ingredients, which affects the final benefits of the products.

[0003] Frozen drinks are a favorite summer snack food. Currently, there are three main categories on the market: ice cream, popsicles, and popsicles. Ice cream is made from purified water, milk or milk powder, cream, and sugar as the main ingredients, with appropriate amounts of various food additives and other auxiliary materials added. With the rise of the health craze, people's requirements for frozen drinks are getting higher and higher. The development of a frozen drink that has both health and wellness effects has become an urgent problem to be solved. However, there are also two problems: (1) The bitter taste of frozen drinks with both medicinal and edible properties; (2) The taste and melting resistance of frozen drinks with both medicinal and edible properties.

[0004] Therefore, it is urgent to develop a medicine-food homologous frozen beverage without bitter taste, good taste and good melting resistance. Summary of the invention

[0005] The present invention aims to solve at least one of the technical problems in the related art to a certain extent. To this end, one object of the present invention is to provide a food-and-medicine frozen drink and a preparation method thereof. The food-and-medicine frozen drink provided by the present invention solves the problems of bitter taste, poor taste and poor melting resistance of food-and-medicine frozen drinks by exploring the various ingredients in the formula, and creates a nutritious, healthy and delicious food-and-medicine frozen drink, so as to promote the innovative development of frozen drink products in the health field.

[0006] Therefore, the first aspect of the present invention provides a frozen drink that is both a medicine and food. According to an embodiment of the present invention, the frozen drink that is both a medicine and food comprises:

[0007] Dendrobium officinale, green natto, emulsifier, stabilizer and compound flavor protease,

[0008] Wherein, the emulsifier comprises polyglycerol fatty acid ester;

[0009] The stabilizer includes at least one selected from locust bean gum, guar gum, and sodium carboxymethyl cellulose.

[0010] Food and medicine substances usually have a unique plant aroma and taste, however, some substances, such as Dendrobium candidum, have a certain bitter taste. In order to enhance the overall flavor of frozen drinks, these ingredients must be combined with other ingredients with strong flavors.

[0011] By studying the flavor substances of ice cream and dairy products and using the basic research on the flavor of functional active substances, a coordination model combining two flavor substances is established to form an innovative flavor system. The inventor uses the combination of Dendrobium candidum and green mannatto to reduce the bitterness of Dendrobium candidum and make the taste of frozen drinks (such as ice cream) softer. This cross-border fusion not only improves the acceptance of frozen drinks, but also brings a novel taste enjoyment to consumers. In addition, the composite flavor protease of the present invention is used to enzymolyze dairy products, and the products after enzymolysis release cheese-characteristic flavor amino acids, peptides and fatty acids, which can also cover up the bad flavor of functional active substances.

[0012] Furthermore, the medicinal and edible raw materials used in medicinal and edible frozen drinks are usually in powder form and rich in fiber. These ingredients will affect the structure and taste of frozen drinks. Studies have shown that the addition of fiber may lead to increased ice crystal formation in frozen drinks, thereby affecting the smoothness of the taste and the effect of cream fusion. In view of this, the inventors have conducted a large number of experimental explorations. According to the characteristics of the influence of fiber, they found that the use of special emulsifiers and stabilizers to optimize the organizational structure of medicinal and edible frozen drinks can effectively reduce the formation of ice crystals and enhance the greasy feeling of frozen drinks. The present invention creatively improves the anti-melting ability of medicinal and edible frozen drinks containing Dendrobium officinale by adding and adjusting the type and amount of stabilizers. The present invention modifies the bitter taste of medicinal and edible frozen drinks containing Dendrobium officinale by adding a composite flavor enzyme and releasing flavor substances such as small molecule peptides, thereby obtaining medicinal and edible frozen drinks with good flavor and taste.

[0013] According to an embodiment of the present invention, the food and medicine frozen drink further comprises dairy products and oils.

[0014] According to an embodiment of the present invention, the medicine-food homologous frozen drink comprises:

[0015] 0.5-2 parts by weight of Dendrobium officinale;

[0016] 15-23.8 parts by weight of green mannatto;

[0017] 9-11 parts by weight of dairy products;

[0018] 16-24 parts by weight of fat;

[0019] 0.1-0.3 parts by weight of an emulsifier;

[0020] 0.15-0.45 parts by weight of a stabilizer;

[0021] 0.05-0.2 parts by weight of composite flavor protease.

[0022] The invention improves the flavor of the frozen drink containing dendrobium officinale and having both medicinal and edible properties, and makes the mouthfeel dense and smooth by selecting suitable raw materials and adjusting the proportion of green natto.

[0023] According to an embodiment of the present invention, the food and medicine frozen drink further comprises 10-20 parts by weight of a sweetener.

[0024] According to an embodiment of the present invention, the dairy product comprises at least one selected from skim milk powder, whole milk powder, whey powder, whey protein powder, and soy protein powder. The dairy product provides the flavor of the milk base and protein for the food-medicine frozen drink.

[0025] It should be noted that the milk powder in the present invention includes but is not limited to whole milk powder, skim milk powder, reconstituted milk powder, whole fat sweetened milk powder, flavored milk powder, formula milk powder and the like.

[0026] According to an embodiment of the present invention, the fat comprises at least one selected from milk fat, butter, cream and vegetable oil. The fat can provide a creamy flavor and increase the fat content for the frozen drink.

[0027] According to an embodiment of the present invention, the vegetable oil includes at least one selected from coconut oil, palm oil, peanut oil and corn oil. The vegetable oil can provide a fat-filled mouthfeel, and is used to synergistically dilute the overly heavy and greasy feeling of using only cream.

[0028] According to an embodiment of the present invention, the emulsifier is polyglycerol fatty acid ester.

[0029] According to an embodiment of the present invention, the stabilizer is locust bean gum, guar gum and sodium carboxymethyl cellulose.

[0030] According to an embodiment of the present invention, the sweetener comprises at least one selected from white sugar, fructose syrup, maltose syrup, and maltitol. The sweetener can provide suitable sweetness for the frozen drink.

[0031] According to an embodiment of the present invention, the sweetener is white sugar and high fructose corn syrup. The sweeteners in the frozen drinks provided by the present invention are preferably white sugar and high fructose corn syrup, because white sugar and high fructose corn syrup are not easy to form bound water with water, and have little effect on the freezing point, taste and anti-melting property of the product.

[0032] According to an embodiment of the present invention, the medicine-food homologous frozen drink comprises:

[0033] 0.5-2 parts by weight of Dendrobium officinale;

[0034] 15-23.8 parts by weight of green mannatto;

[0035] 9-11 parts by weight of dairy products;

[0036] 10-14 parts by weight of milk fat;

[0037] 6-10 parts by weight of vegetable oil;

[0038] 10-20 parts by weight of a sweetener;

[0039] 0.1-0.3 parts by weight of polyglycerol fatty acid ester;

[0040] 0.08-0.22 parts by weight of sodium carboxymethyl cellulose;

[0041] 0.06-0.1 parts by weight of guar gum;

[0042] 0.05-0.11 parts by weight of locust bean gum;

[0043] 0.05-0.2 parts by weight of composite flavor protease.

[0044] The second aspect of the present invention provides a method for preparing the food-medicine-sustaining frozen drink of the first aspect. According to an embodiment of the present invention, the method comprises:

[0045] S1: mixing the composite flavor protease with the dairy product, performing enzymolysis, and obtaining an enzymolysis product;

[0046] S2: mixing the enzymatic hydrolysis product with the Dendrobium officinale, green natto, oil, emulsifier, stabilizer and sweetener, and homogenizing the mixture to obtain the food and medicine frozen drink.

[0047] According to an embodiment of the present invention, step S1 further comprises inactivating the enzymatic hydrolysis product.

[0048] According to an embodiment of the present invention, step S2 further comprises:

[0049] S2-1: Obtaining ultrafine powder of Dendrobium officinale;

[0050] S2-2: The superfine powder is mixed with oil, emulsifier, stabilizer, sweetener and green natto, and subjected to homogenization, aging and cooling treatments.

[0051] According to an embodiment of the present invention, the homogenization pressure during the homogenization process is 100-130 Bar.

[0052] According to an embodiment of the present invention, the aging treatment time is 2-4 hours and the temperature is 0-6°C.

[0053] According to an embodiment of the present invention, the aeration rate of the cooling process is 30-50%.

[0054] The present invention provides a method for developing a food-medicine homologous frozen beverage and applying a core process. The prepared frozen beverage is both nutritious and healthy and delicious, and can cover up the bitter flavor of the original food-medicine homologous medicine, thus realizing the transformation of food-medicine homologous frozen beverage.
