Ice cream is a frozen food with high nutritional value, which can be enjoyed in all seasons and is suitable for all ages. It contains a variety of vitamins, amino acids, calcium, protein, fat, etc. necessary for the human body, and is easy to digest and absorb after consumption. Eating ice cream is more common in some countries and is a must-have food on the family table. It is regarded as an indispensable dessert and snack food. Since the 1990s, our country has enhanced its ice cream technology. In 1997, the national ice cream production was 1.18 million tons, 11 times that of 1987. As people's living standards continue to improve, exotic ice cream products are gradually gaining popularity. At present, consumers in our country, especially middle-aged and elderly people, focus on eating ice cream in the summer, thinking that it is just a food to relieve summer heat. This is a traditional consumption concept. Eating ice cream in all seasons is of great benefit to human health. Currently, consumers have a psychological misunderstanding that eating ice cream will make them fat, or they will eat less or even avoid eating ice cream and dairy products in order to lose weight. In fact, in some countries, people's comprehensive fat intake, especially the amount of dairy products such as ice cream, far exceeds that of our country. For example, the annual consumption per person in Finland is 9 kilograms, Sweden is 8.6 kilograms, the United Kingdom is 5.5 kilograms, and our country is 0.9 kilograms. Higher fat intake requires weight loss, but Chinese consumers are far from reaching such a high intake. At the same time, according to relevant data, the per capita calcium deficiency rate in my country is relatively high, and it is necessary to increase the consumption of a large amount of milk and its products every day. Some experts also say that eating a moderate amount of ice cream products every day will not make you gain weight. For example, it is very beneficial to eat some series of products developed according to the tastes and habits of Chinese people such as Medengao, Heluxue, and Nestlé every day. According to analysis by relevant experts, my country's annual ice cream production will reach about 2.5 million tons in the future, and per capita consumption will reach 2.4 liters per year. At that time, ice cream will no longer be a "patent" for cooling off in the summer and for children, and will shift from consumer fashion to a leisure product. The problem of people's "fatness" and "thinness" is a matter of common concern to everyone. In the past, it was thought that obesity was the result of fat accumulation in the body due to excessive nutrient intake and lack of necessary exercise; however, obesity is now recognized as a disease. All this is closely related to genetics, physical constitution, daily eating habits, work, exercise and rest. Among frozen drinks, the one with the highest nutritional value is "ice cream". As we all know, milk is a food with high nutritional value and complete nutritional components, and ice cream is one of its products. According to international and national product standards, the nutritional content of general cream ice cream is 2.8-3 times that of milk, which self-evidently illustrates the nutritional value level of ice cream. High-end cream ice cream is prepared with neutral milk fat. Some companies have switched to vegetable oils to replace the fat part of low-end ice cream, and have developed low-fat ice cream. The milk protein in ice cream is a relatively complete protein (including amino acids, arginine, leucine, phenylalanine, cystine, lysine, valine, methionine, etc. that the human body must supplement daily) Its digestibility reaches 96%. In addition to the heat produced by carbohydrates, it also contains various substances in milk that are needed to promote development (such as calcium, phosphorus, potassium, sodium, chlorine, sulfur, iron, etc.) and promote development, regulate physiological functions, and maintain osmotic pressure and pH. Various vitamins, such as products added with fresh fruits also contain vitamin C. Based on the above nutrients, the total dry matter of cream ice cream should be no less than 34%, the fat content should be no less than 10%, the non-fat milk solids should be no less than 10%, and the sucrose should be no less than 15%. Therefore, according to calculations, the caloric value per kilogram of the product is about 2,000 kcal (high-grade cream ice cream is 2,300 kcal, while milk ice cream is 1,400 kcal). According to the composition of ice cream, the product has 800-1000 kcal per kilogram; while popsicles and ice cream products have only 450-500 kcal per kilogram because they are fat-free and dairy-free. Calculated based on the above data, generally each person consumes one serving of 50-150 grams of ice cream per day, which has only 100-300 kcal of calories; or two sticks of ice cream or popsicles have 80-130 kcal, which is only the daily dietary intake of people. 1/10-1/15 of the amount. According to my country's current economic and consumption levels, it generally does not cause the problem of "fatness" in the body.
