Will nutrients be lost when juicing fruits?

Many people love to eat fruits. Not only do they supplement the human body with various vitamins, but fruits are generally sweet, which can satisfy foodies' taste enjoyment. They can also beautify, rejuvenate, and whiten the skin. Eating fruits every day has many benefits for the human body. Fruits can be eaten directly or squeezed into juice and drunk. However, many people think that juicing fruits will cause nutrient loss. Will nutrients be lost when juicing fruits? Let’s take a look at it next.

1. Does juicing destroy nutrition?

Using a juicer to squeeze juice will destroy the nutrients in the fruit. Because when stirring, the vitamin C in the fruit reacts with air to oxidize, which is most likely to cause a large loss of vitamin C. No matter how advanced the juicer is, it cannot fundamentally solve the problem of nutrient loss when exposed to oxygen, nor can it solve the problem of juice being digested and absorbed too quickly, let alone the problem of juice tasting very sweet and being easy to drink too much.

2. What nutrients will be lost when juicing

1. Heavy loss of vitamin C

The direct consequence of juicing without blanching is the loss of vitamins, flavonoids, anthocyanins and other antioxidant ingredients in fruits and vegetables, even if you drink the juice immediately after juicing.

2. A lot of dietary fiber is lost

Insoluble elements such as calcium, dietary fiber, etc. will also be retained in the residue. Drinking fruit juice will reduce people's intake of dietary fiber rich in fruits, which has health benefits of preventing and reducing diabetes, cardiovascular diseases, etc., and can also effectively stimulate gastrointestinal motility and promote defecation.

3. How to squeeze juice with a juicer to reduce nutritional loss

1. Selection of raw materials

When making juice, try to choose fresh fruits and vegetables. Fruits and vegetables stored in the refrigerator are not necessarily fresh. Also, if fruits and vegetables are kept for too long, the vitamins in them will be destroyed and the nutritional value will be lost.

2. Peel issues

Many people like to peel fruits when eating them or making juice, but they don’t know that the skin of some fruits, such as apples and grapes, also has nutritional value. Peeling will lose some of these nutrients. In fact, it may be better to wash the fruits and keep the skin.

3. Juice should be made and drunk immediately

Fresh juice contains a lot of vitamins. If it is left for a long time, it will be oxidized by the air and the nutrients will be lost, so it should be made and drunk immediately. If the juice is not boiled, it should be drunk immediately after squeezing and cannot be stored. It can be said that the loss of vitamins and antioxidants is increasing every minute. If the enzyme has been inactivated after blanching and then juicing, it should be okay to store it in a sealed container in the refrigerator for a day. Be careful to minimize the contact between juice and air to avoid oxidation and discoloration.

Juice that is not blanched will turn brown very easily. Browning does not mean that the fruit and vegetables are toxic or harmful, and they can still be drunk. It just means that the polyphenol health-promoting ingredients in fruits and vegetables are oxidized when exposed to oxygen, and the antioxidant effect will decrease. At the same time, the flavor will gradually change during storage and lose its original freshness and deliciousness.

4. Blanching of fruits and vegetables

Many people don’t know that in commercial production of fruit and vegetable juice, the fruits and vegetables often need to be blanched. In other words, the fruits and vegetables need to be slightly blanched in boiling water to "kill" the oxidases and soften the tissues slightly before juicing them. This not only reduces the loss of vitamins and increases the juice yield, but also makes the juice bright in color and less likely to turn brown. Especially those vegetables that are not sour, such as carrots, greens, celery, and sweet corn, must be blanched before juicing.
