Preparation method of ice cream containing rich unpolished rice and purple sweet potato small round sheets

Abstract

The invention discloses a preparation method of ice cream containing rich unpolished rice and purple sweet potato small round sheets. Coarse cereal small round sheets produced by a double-screw extruder are adopted and cattle bone powder is added; the adding amount of coarse cereals can be improved to 20 percent to 60 percent so that the nutrient value of the ice cream is remarkably improved; meanwhile, the taste, expansion ratio and anti-thawing performance of the ice cream are also ensured; various raw materials which are added in an ice cream production process are biological raw materialsand no chemical additive is added, so that the ice cream is healthy and environmentally friendly.

Description

Technical field [0001] The invention relates to an ice cream, in particular to a preparation method of an ice cream rich in brown rice and purple sweet potato chips. It belongs to the technical field of frozen drinks. Background technique [0002] Ice cream has a delicate, smooth and refreshing taste. It is a popular food for relieving heat. It uses water, dairy products, sugar and edible fats as the main raw materials, and supplements some food additives. It is mixed, sterilized, homogenized, aging, and frozen. Frozen food with volume expansion made by processes such as freezing and freezing. [0003] With the improvement of living standards, people are pursuing more and more diversified foods. As far as ice cream is concerned, conventional ice cream products can no longer meet people's needs, and there are more diversified requirements for ice cream flavors. [0004] Brown rice is the caryopsis with the outer protective cortex and the rice husk removed, and the inner protective c...

Problems solved by technology

[0005] But directly adding brown rice flour or brown rice paste will affect the mouthfeel of ice cream, and also significantly affect the melting resistance of ice cream. For example, Chinese invention patent CN101803670A discloses a brown rice ice cream and a preparation method thereof, which directly pulverizes brown rice to obtain brown rice flour and Add in ice cream to obtain brown rice ice cream, but in order to ensure its expansion rate, the brown rice addition in this invention is less than 10% of the total amount of ice cream. After testing, when the addition reaches more than 20%, not only its taste will be greatly affected Influence, and will also significantly affect the melting resistance of ice cream, so in order to increase the amount of brown rice and other miscellaneous grains added, and then improve the nutritional value of ice cream, it is necessary to study a preparation method of ice cream rich in brown rice and purple sweet potato chips
