Freshly squeezed juice can't completely replace fruit during the Golden Week. In the middle and high-end restaurants in Beijing, the sales of freshly squeezed juice are extremely hot, and the sales volume far exceeds that of fruit wine and juice drinks, making it one of the top drinks in the catering industry. Our reporter learned from a survey of many catering enterprises in Beijing that freshly squeezed juice can be divided into three categories: fruit, vegetable and mixed. There are thirty or forty kinds of freshly squeezed juice, three or four kinds of freshly squeezed juice in most catering enterprises, more than 10 kinds of freshly squeezed juice in large catering enterprises, and five to 10 kinds of freshly squeezed juice provided by star hotels. Among the many varieties of freshly squeezed juice, watermelon juice, cantaloupe juice, orange juice, mango juice, pineapple juice and peach juice are widely favored by consumers, and tomato juice is the best among vegetable juices. The price of each bundle of freshly squeezed juice is mostly between 15 yuan and 30 yuan. According to estimates, the prices of raw materials such as fruits, vegetables, honey and sugar will not exceed 20% of the price of freshly squeezed juice, and the profit rate of catering enterprises can be as high as 80%. Liu Cheng, a senior engineer of Beijing Food Research Institute, said in an interview with this reporter that the fresh-squeezed juice in China has been growing rapidly for 10 years, and the consumption of fresh-squeezed juice in 2003 has exceeded 10 billion yuan. Freshly squeezed juice can effectively eliminate human toxins, prevent gastrointestinal diseases and promote normal liver and kidney functions. Drinking freshly squeezed juice regularly is helpful for women's beauty. Nutritionists advise adults to eat 400 to 500 grams of fruit every day. Old people and children drink freshly squeezed juice in moderation, which is helpful for digestion, moistening intestines and supplementing nutritional deficiency in diet. Some people don't like drinking boiled water, but sweet fruit juice can increase their drinking water and ensure their body's need for water. Freshly squeezed fruit juice retains a considerable amount of nutrients in fruit, such as vitamins, minerals, sugar and pectin in dietary fiber, which has great advantages compared with water and carbonated drinks. However, adding sugar, sweeteners, sour materials, spices and other ingredients to flavor freshly squeezed juice also plays a vital role. There is a considerable gap between the nutrition of freshly squeezed juice and fruit, and freshly squeezed juice cannot completely replace fruit. The main reasons are as follows: freshly squeezed juice basically does not contain cellulose in fruit; The process of crushing and pressing destroys some vitamins that are easy to be oxidized in fruits; Lack of certain nutrients in fruits will adversely affect the overall nutritional function; Chemicals such as sweeteners, preservatives, coagulants to clarify fresh fruit juice and additives to prevent fruit juice from discoloring will inevitably affect the nutritional quality of fruit juice. Normal adults drink about 2500 ml of water every day, of which110 is only freshly squeezed juice or pure juice, that is, drinking a glass of juice every day is enough. Consumers should not expect fruit juice to provide all-round nutrition needed by the body. It is just a drink with high nutritional value. Others think that fruit juice, especially fresh fruit juice, pure fruit juice or sugar-free fruit juice, has no calories and will not make people fat, which is wrong. In fact, a cup of 25mg pure apple juice provides more energy than 50g steamed bread. The insiders believe that mixed juice is the development direction of freshly squeezed juice. Freshly squeezed juice can be combined with many foods to make new juice with different characteristics. Some fruits are rich in nutrition, but the taste is not easy to be accepted by most consumers. As long as it is paired with other fruits with good taste, it tastes better. For example, after grapefruit juice is mixed with citrus juice, pineapple juice, mango juice and apple juice, the taste can be loved by most consumers. Freshly squeezed juice is mixed with tomato juice, cucumber juice, celery juice, lettuce juice, spinach juice, carrot juice, etc. And salt, spices and citric acid. In addition, freshly squeezed juice can be mixed with milk to make juice milk. In recent years, the sales volume of juice milk has increased by about 50%. In an interview with this reporter, Dr. Huo from the Institute of Nutrition and Health of China Center for Disease Control and Prevention said that some catering enterprises now process fruit juice with rotten raw materials, or add water to fruit juice, or add chemicals such as pigments and sweeteners to fruit juice without restraint. It is usually impossible for catering enterprises to process juice on the spot in a vacuum aseptic environment, so it is difficult to fundamentally ensure the hygienic level of juice. Relevant departments should formulate national mandatory standards and industry standards for freshly squeezed juice as soon as possible, and make specific specifications for physical and chemical indicators and health indicators.
