Description

Technical Field

[0001] The invention relates to the technical field of frozen drinks, and in particular to a medicinal and edible frozen drink containing Cistanche deserticola 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] Cistanche deserticola, hawthorn pulp, emulsifier, stabilizer,

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

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

[0010] Food and medicine substances usually have a unique plant aroma and taste, however, some substances, such as Cistanche deserticola, 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 was established to form an innovative flavor system. The inventor used the combination of Cistanche deserticola and hawthorn syrup to reduce the bitterness of Cistanche deserticola and make the taste of frozen drinks (such as ice cream) softer. This fusion not only improves the acceptance of frozen drinks, but also brings a novel taste enjoyment to consumers.

[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 Cistanche deserticola by adding and adjusting the type and amount of stabilizers.

[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] 0.05-2.5 parts by weight of Cistanche deserticola;

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

[0020] 0.2-0.7 parts by weight of stabilizer.

[0021] The invention improves the flavor of the food-medicine-containing frozen beverage containing Cistanche deserticola by selecting suitable raw materials and adjusting the proportion of hawthorn pulp, and makes the mouthfeel dense and smooth. The anti-melting ability of the food-medicine-containing frozen beverage containing Cistanche deserticola is improved by adding and adjusting the type and amount of stabilizers.

[0022] It should be noted that the source of the hawthorn pulp in the present invention can be directly purchased from the market, or purchased hawthorns can be washed, and then an appropriate proportion of hawthorn and water are added for squeezing, stirring, and filtering. When preparing freshly squeezed hawthorn pulp, the ratio of hawthorn to water can be 1: (0.75-1.2), preferably, the ratio of hawthorn to water can be 1: 1.

[0023] According to an embodiment of the present invention, the food and medicine frozen drink further comprises 10-25 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.
