According to one aspect of the invention, the invention provides an ultra-high protein ice cream comprising: 5-30 parts by weight of a sweetener; 0-35 parts by weight of fruit juice and/or jam; 20-60 parts by weight of raw milk and dairy products; 0-10 parts by weight of soybean protein powder; 0-30 parts by weight of nut pulp; 0-30 parts by weight of coconut milk; 0-3 parts by weight of edible oil; and 0.1-0.8 part by weight of stabilizer, wherein the dosage of the soybean protein powder, the nut pulp and the coconut pulp is not 0 part by weight at the same time, and the protein content and the fat content in the ice cream with ultrahigh protein content are not less than 12% by weight and not more than 5% by weight respectively.
The ice cream with the ultrahigh protein content provided by the embodiment of the invention takes the raw milk, the dairy product and optionally the fruit juice, the jam, the soybean protein powder, the nut pulp and the coconut pulp in the proportion as raw materials, so that the protein content in the ice cream can be obviously improved, the fat content in the ice cream can be effectively reduced, the protein content in the ice cream with the ultrahigh protein content provided by the invention is not lower than 12 weight percent, the fat content is not higher than 5 weight percent, the nutritional value is rich, and the ice cream with the ultrahigh protein content has unique taste and flavor.
Most of protein sources in the conventional ice cream are milk proteins, and a single protein source is high in cost and difficult to meet the requirement of ultrahigh protein content, and simultaneously, the balance of flavor release and other nutritional ingredients is influenced. The inventor finds that by adopting the vegetable protein and the animal protein as protein sources, the protein content in the ice cream can be effectively increased, and the fat content in the ice cream can be effectively reduced. The inventor also finds that by using the plant protein and the animal protein as protein sources, the fishy smell which is easily generated by using the animal protein alone can be covered. In addition, by adjusting the proportion of the vegetable protein and the animal protein, namely the proportion of the raw milk and the dairy product to the fruit juice, the jam, the soybean protein powder, the nut pulp and the coconut pulp, the ice cream with ultrahigh protein content can have unique taste and flavor. Therefore, the requirements of people on the nutritional ingredients can be met, and the requirements of people on ice creams with different tastes and flavors can also be met.
According to a specific embodiment of the present invention, the sweetener may be at least one selected from the group consisting of sucrose, fructose syrup, maltose syrup, glucose syrup, lactose, honey, sugar alcohol, sodium cyclamate, aspartame, sucralose, acesulfame potassium and neotame. Therefore, the sweetener type can be selected according to different requirements, so that the nutritional value of the ice cream with ultrahigh protein content is further improved, and the ice cream with ultrahigh protein content has unique taste and flavor.

According to a second aspect of the invention, there is also provided a method of making the ultra-high protein ice cream of the above embodiments, comprising: carrying out first standardization treatment on raw milk so as to obtain standardized raw milk; mixing standardized raw milk, sweetener, dairy product, stabilizer and optionally fruit juice, jam, soybean protein powder, nut pulp, coconut pulp and edible oil to obtain mixed solution; carrying out second standardization treatment on the mixed solution so as to obtain a standardized feed liquid; sterilizing the standardized feed liquid to obtain a sterilized product; and homogenizing, cooling, aging, freezing, filling and quickly freezing the sterilized product in sequence so as to obtain the ice cream with ultrahigh protein content.
It should be noted that "optionally" mainly means that fruit juice, jam, soy protein powder, nut pulp, coconut pulp and edible oil and fat may be optionally added or not added according to actual needs. Wherein both the "first standardisation treatment" and the "second standardisation treatment" refer to bringing the respective raw material or mixed liquor to a predetermined desired total dry matter content.
Therefore, by adopting the method for preparing the ice cream with the ultrahigh protein content, the ice cream with the ultrahigh protein content can be effectively prepared, and the prepared ice cream with the ultrahigh protein content has the characteristics of high protein and low fat, is rich in nutritional value and has unique taste and flavor.
According to a particular embodiment of the invention, the ultra-high protein content ice cream may have a protein content not lower than 12% by weight and a fat content not higher than 5% by weight. Therefore, the prepared ice cream with ultrahigh protein content can simultaneously meet the requirements of people on nutrient components and healthy diet.
According to the specific embodiment of the invention, the sterilization treatment can be performed by a traditional sterilization process or a pasteurization process, the traditional sterilization process can be completed by insulating the mixed solution at 80-85 ℃ for 10-15 minutes, and the pasteurization process can be completed by insulating the mixed solution at 90-105 ℃ for 20-60 seconds. Therefore, the harmful mixed bacteria can be effectively killed, and the loss of nutrient components can be reduced as much as possible.
According to the embodiment of the invention, the temperature of the homogenizing can be 65-75 ℃, the total pressure can be 130-150 bar, the primary pressure can be 104-120 bar, and the secondary pressure can be 24-30 bar. Therefore, the residual small particles in the sterilization product can be further crushed, and the prepared ice cream with ultrahigh protein content has finer taste and stronger stability.
According to the embodiment of the invention, the aging can be carried out at the temperature of 0-4 ℃ for 2-48 hours. The inventor finds that the aging under the condition can fully hydrate the fat, the protein and the stabilizer, so that the viscosity of the liquid-phase sterilization product is improved, the expansion rate is improved during freezing and stirring, and the unique taste and flavor are endowed to the ice cream with ultrahigh protein content.
According to a specific embodiment of the invention, the freezing can be performed in a 1000L or 2000L continuous freezer, and the outlet temperature of the freezer can be between-2 and-5 ℃. The inventors have found that freezing under these conditions provides ice cream with an ultra-high protein content that has a better texture and flavor, e.g., a soft, soft texture, is less prone to devitrification, and has a greater resistance to melting.
According to a specific embodiment of the present invention, the quick freezing may be performed at a temperature of not higher than-35 degrees celsius using 688, 800 or 1250 tunnels.
