Technical Field

The invention relates to ice cream, in particular to fruitless medlar bud tea ice cream and a preparation process thereof.

Background

The existing ice cream has various varieties, common milk ice cream and mixed fruit juice ice cream are available, and other varieties of ice cream are continuously developed. For example, the patent application number of 201710436360.X, which is published by the national intellectual property office of the people's republic of China in 2018, 12 months and 18 days, is an invention patent application named as ' black fruit medlar flower color ice cream and a manufacturing method thereof ', and the formula of the ice cream disclosed by the invention is as follows: 40-70 parts of milk, 5-8 parts of eggs, 7-12 parts of white granulated sugar, 8-12 parts of lycium ruthenicum mill pulp, 0.13-0.19 part of xanthan gum, 0.13-0.18 part of molecular distillation monoglyceride, 0.05-0.12 part of CMC, 3.1-3.8 parts of milk powder and 11.5-13 parts of water. The preparation method of the ice cream comprises the following steps: softening and pulping, mixing the raw materials and auxiliary materials, homogenizing, sterilizing, cooling and aging, freezing, filling and hardening. The lycium ruthenicum ice cream is based on common ice cream, and endows products with special taste, flavor and color by using the nutrition and health-care characteristics of lycium ruthenicum and special pigments thereof. The nutrition and health care effects of the ice cream are increased, the variety of the ice cream is enriched, various preferences of cold drink consumer groups are met, and the black wolfberry fruit ice cream has good market prospects in aspects of expanding deep processing of the black wolfberry fruit and the like.

Ancient doctor (compendium of materia medica) calls that the medlar bud is Tianjing grass, bitter, sweet and cool in nature and flavor, entering the four meridians of heart, lung, spleen and kidney. It is considered from dietetic herbal medicine that it is "hard and tough, resistant to aging, wind-dispelling, tonifying muscles and bones, benefiting people and eliminating consumptive disease".

The ice cream is soft and delicious frozen food which is prepared by taking milk or dairy products and cane sugar as main raw materials, adding eggs or egg products, emulsifying agents, stabilizing agents, spices and other raw materials, and processing the raw materials by mixing, sterilizing, homogenizing, maturing, congealing, forming, hardening and the like. The ice cream has high nutritive value, fat content of 6-12% (some varieties can reach more than 16%), protein content of 3-4%, sucrose content of 14-18% (the sugar content of fruit ice cream reaches 27%), and contains vitamin A, B, D, etc., and the calorific value can reach 8 joules/gram. Therefore, the ice cream is a nutritious cold drink food for relieving summer heat.

As the ice cream industry grows larger and its production also increases at unprecedented rates, the market is expanding dramatically.

People not only have higher and higher requirements on ice cream, but also have increasingly more stringent requirements on nutrition, flavor, color and packaging of varieties, and consumers have great changes, along with the continuous increase of solid matters, the consumers are fashionable and loved to not only provide people with cooling and summer heat relieving feelings, but also pay more attention to the unique nutrition and functionality of the ice cream. In the traditional ice cream, most of the ice cream is prepared by using milk as a main raw material, adding a certain proportion of sugar, a stabilizer, an emulsifier and other auxiliary materials, and coagulating, and has single taste and higher fat, sugar and cholesterol. With the improvement of the quality of life and the change of consumption concept, the demand of people on common ice cream is reduced, and the demand of novel ice cream with various varieties, unique taste and unique flavor and nutrition and health care function is gradually increased. In the face of this trend, various ice creams are available on the market, for example, health ice cream is one of ice creams aiming at improving human health. The development of unique wolfberry products in Ningxia becomes a requirement for the development of Ningxia.
