It is rich in unsaturated fatty acid, polyphenol plant protein and flavonoid substances of natural cocoa butter, and has unique taste, and also has the functions of improving cardiac and cerebral blood vessels, enhancing antioxidant capacity, etc., so that it is different from candy. The chocolate has rich nutrition, about 50 g of carbohydrate, about 30g of fat, about 15 g of protein and more zinc, vitamin B2, iron, calcium and the like in every 100 g, but the chocolate has single eating form and health care function for many years.
Frozen beverages are of various types and are commonly ice cream, slush, popsicle, edible ice, sweet ice and the like. In order to enrich the appearance and taste of frozen beverages, a chocolate layer is generally coated on the outer surface of the frozen beverage, which can also be called chocolate crust, such as stick ice cream, ice cream and the like coated with chocolate. However, the following problems exist in the frozen beverage coated with chocolate on the market at present: the chocolate coating is cracked and fragile, and the coated ice cream is easy to collapse, overflow, and the like, so that the edibility and the attractiveness of the product are seriously affected; the thickness of the chocolate which can be coated on the surface of the existing frozen drink coated with the chocolate at one time is thin, the gram weight is low, if the gram weight is to be improved, the coating is carried out twice or more times in preparation, but the taste of the chocolate is difficult to keep smooth after the operation, the chocolate is very slow to dry after the coating, the chocolate is easy to wear during packaging, the appearance and the production efficiency of the product are affected, and the development of novel frozen drink with mellow chocolate is not facilitated; in order to ensure enough viscosity and brittleness, the existing chocolate needs to be added with more white granulated sugar, wherein the white granulated sugar belongs to disaccharide, the common dosage is about 30 percent, and the sweetness and the heat are high in the product with less sugar not less than 20 percent.

Figure BDA0002470201260000121
It can be seen from the data in tables 1 and 2 that the addition of the juice polysaccharide to the chocolate material significantly improved the cracking problem of the chocolate when coated with ice cream. Especially when the final addition amount of the green juice polysaccharide is 10% -15%, and the prepared chocolate is added in the form of the green juice polysaccharide concentrated solution by the specific preparation method provided by the application, the prepared chocolate is moderate in viscosity, smooth in appearance, rich and rich in taste, smooth in surface and free of flow marks after being coated with a large gram weight at one time on ice cream, does not have cracking phenomenon, and shows very remarkable anti-cracking effect.
The mass ratio of coconut oil (lauric oil) and palm oil (non-lauric oil) in the total chocolate oil was further optimized by taking the green juice polysaccharide content in example 1 as the best example, the oil mass ratio in table 3 was referred to for preparation examples 13-18, and the mass ratio of the following oils could be adjusted at 50% of the total amount, wherein the coconut oil was all derived from the ingredients, the palm oil was derived from the green juice polysaccharide concentrate, and the rest was added separately by ingredients, and the specific calculation and adjustment method was not described.
The mass ratios of the oils used in specific examples 13 to 18 and the chocolate ice cream coating effect obtained are shown in Table 3.
TABLE 3 Effect of chocolate fat ratio on ice cream coating effect
Figure BDA0002470201260000122
