It is economical and convenient, and it is a good cosmetic method.

Three key words

Natural fruit juice refers to unfermented but fermentable fruit juice processed by various methods, or water equivalent to the natural water lost in the process of fruit juice concentration is added to concentrated fruit juice, which has the color, flavor and soluble solid content of the original pulp. The fruit juice content is 100%. This kind of juice is also called pure juice, raw juice or natural juice.

Two ingredients

1, natural ingredients

Fruit juice: Natural fruit juice obtained from fruits by mechanical or physical methods.

Minerals and vitamins: natural nutrients that remain after natural fruits are made into juice drinks.

Moisture: The main component of fruit juice is water, and the "water" here mainly refers to the original moisture of fruit.

Sugar: Fructose, sucrose and glucose are natural edible sugars, and their function is to provide energy for people. However, too much sugar or excessive intake of this sugar will cause obesity, hypertension and other diseases.

2. Additives

Sweeteners: Sweeteners can increase sweetness or be used as sugar substitutes, such as sorbitol, stevia powder, sodium cyclamate and aspartame. Because of its low molecular weight, it can not be decomposed and absorbed by human body, so sugar-free juice drinks will also be used. Sweetener is safe in a certain dose, but excessive use will have side effects. Excessive sweeteners will stay in the stomach and cause diarrhea.

Edible preservatives: The most commonly used preservatives are benzoic acid and sorbic acid. If it is added in excess, it will affect the taste and cause gastrointestinal discomfort. Generally speaking, if the processing technology of fruit juice is advanced, there is no need to add preservatives.

Four misunderstandings of fruit juice consumption

First of all, you can't tell pure juice from juice drinks.

According to relevant surveys, 73% consumers don't know the difference between pure juice and juice drinks. According to insiders, there are three kinds of fruit juices that consumers often drink in the market, namely pure fruit juice, fruit juice beverage and fruity beverage. Among them, pure fruit juice refers to the fruit juice with the fruit juice content of 100%. Most of them adopt advanced production equipment such as aseptic filling, so that the final product has the color, flavor and soluble solid content of the original fruit pulp. The fruit juice content of fruit juice beverage is between 30 %~ 10%, which is made of water, sugar solution, sour agent and so on. To the juice. If the fruit juice content is lower than 10%, it is a fruity beverage.

The second is that freshly squeezed juice is healthier.

Most consumers think that freshly squeezed juice is safer, and only 15.6% consumers think that pure juice is safer. Nutrition experts pointed out that fruit juice is an industrialized product with modern equipment, which meets or even exceeds the requirements of national health indicators and is safer to drink. Household fresh press can't sterilize fresh juice in time, and the fresh juice is not sealed in the process of fresh pressing, which is easy to cause pollution, and the juice squeezed without color protection measures is easy to oxidize and brown. When the juicer is used, it is simply washed with clear water, which can not guarantee the thorough disinfection of the juicer.

Third, most consumers don't know that drinking pure juice also has the best time.

The survey found that consumers who like to drink pure juice choose to drink it after dinner. In this regard, nutritionist Dr. Pan Xingchang said that although drinking fruit juice is like eating fruit, you can drink it at any time, but it is most suitable for breakfast. Drinking a glass of juice every morning can not only stimulate appetite, but also replenish water and clean up the gastrointestinal tract.

Fourth, I am worried that drinking pure juice will make me fat.

The survey also found that some female respondents thought pure fruit juice was too sweet and worried that drinking pure fruit juice would lead to obesity. In this regard, Cai, vice chairman of chinese institute of food science and technology, believes that the sugar contained in pure fruit juice is the raw sugar contained in the fruit itself, and drinking pure fruit juice in moderation will not make you fat. Pure fruit juice contains more vitamins, minerals and trace elements than fruit juice drinks. For modern urbanites with increasingly tense life rhythm, drinking pure fruit juice is one of the ideal choices to supplement vitamins, minerals and trace elements.

The new era of fruit juice consumption

Drinking fruit juice all the year round has many benefits to the human body.

First of all: Fruit juice is nutritious. Fruit juice contains a variety of organic acids, vitamins and minerals. These natural trace elements are more easily absorbed and utilized by human body than synthetic trace elements.

Second: Fruit juice can supplement the water needed by human body. Under normal circumstances, adults need about 2500ml of water every day. When they exercise at high temperature and sweat a lot, the water demand may even reach more than 5000ml a day.

Third: Dietary fiber in fruit juice is beneficial to human body. Dietary fiber is closely related to human health and is called the seventh largest nutrient. Fruit juice containing pulp is rich in cellulose, hemicellulose, polysaccharide and pectin, which is beneficial to human health.

Fourth: Although fruit juice has no crisp taste, it is more suitable for children and the elderly. Especially easy to digest and absorb, convenient to drink and rich in nutrition. Fifth, in the off-season of fruit, fruit juice can adjust the season of fruit, which is easy to store, not limited by the season of origin, and easy to carry. Replacing fruit with liquid fruit can supplement human nutrition.

In western countries, consumers will drink pure fruit juice as an important means to supplement vitamins, minerals and trace elements. Statistics show that the average annual fruit juice consumption of Americans is 45 liters, that of Germans is 46 liters, and that of Japanese and Singaporeans is 16- 19 liters. The average annual consumption of fruit juice in China is less than 65,438+0 liters. Although more than 70% consumers in China are aware of the importance of vitamin and mineral supplements, only about 30% consumers choose to drink pure fruit juice. At present, the intake of vitamins and minerals is generally insufficient and unbalanced in China, while pure fruit juice is rich in vitamin C, carotene, vitamin B group and trace elements such as calcium, magnesium, iron and zinc. The lack or imbalance of vitamins and minerals will lead to other nutrients not being absorbed and metabolized by the human body, which will lead to many diseases. "Drinking milk can supplement calcium, and drinking pure fruit juice can supplement vitamins, which should become the nutritional knowledge of China residents."

At present, the nutritional value of milk and other beverages has been recognized by the public, but the nutritional value of pure fruit juice in vitamin supplementation has not been recognized by consumers. Experts believe that it is a good habit to drink two cups of fruit juice (500ml) every day, which can meet people's needs for different vitamins, minerals and trace elements.

Market research shows that many domestic consumers have not formed the habit of drinking fruit juice, especially the nutritional value of 100% pure fruit juice has not been discovered. At present, insufficient and unbalanced intake of vitamins and minerals is widespread in China. The lack or imbalance of vitamins and minerals will lead to other nutrients not being absorbed and metabolized by the human body, which will lead to many diseases. Fruit juice is rich in vitamins, minerals and dietary fiber needed by human body. Such as vitamin C, carotene, vitamin B and trace elements such as calcium, magnesium, iron and zinc. Therefore, experts suggest that consumers should learn to drink fruit juice daily, especially 100% pure fruit juice, reasonably supplement vitamins and minerals, and balance body nutrition.
