In the hot summer, the hot weather is unbearable. Drinks have come into people's sight again. Of course, orange juice is the one that consumes more juice drinks. The content of VC in oranges is not low, with 33 mg of VC per 100g. Moreover, oranges are also loved by everyone because of their sweet and sour taste, But is it true that a bottle of orange juice can be squeezed from several oranges as big as the ones on the package?
We know that the organic acid in oranges can promote digestion. When you have eaten greasy food or accumulated food, you can eat an orange after dinner, or have a glass of orange juice, which can relieve the greasy food The effect of accumulated food, from the perspective of traditional Chinese medicine, is that oranges are sweet, sour, cool in nature, and have the effect of promoting fluid and thirst, appetizing and reducing qi. Moreover, oranges are rich in VC and VP, which can enhance the body's resistance, enhance the elasticity of capillaries, and reduce blood cholesterol. Therefore, patients with hyperlipidemia, hypertension and arteriosclerosis can eat more oranges in season.
Oranges are also rich in cellulose and pectin, which can promote intestinal peristalsis, help clear the intestines and defecate, and eliminate harmful substances in the body. And from the perspective of traditional Chinese medicine, oranges are not as easy to burn as oranges, so people with any constitution can eat them.
But the above advantages are attributed to oranges. If you want to drink orange juice, it will not have such great effect. First of all, VC will lose a lot in the process of squeezing. Unless you add VC tablets in the process of squeezing, it can not only increase the VC content, but also prevent browning reaction in the juice. Secondly, it is the dietary fiber that you will lose most during the juice pressing process. If you have bad teeth and are not sensitive to chewing, it is better to drink than not to drink. If you are healthy, you'd better eat the whole fruit.
Most of the orange juice on the market is 10%, and the rest 90% is added with water, white granulated sugar, thickening agent, etc. In order to taste more similar to orange juice, orange juice essence may also be added. We can see from the price. A 500ml glass of orange juice is generally 2.5 yuan, and the price of oranges is 5 or 6 yuan. After removing the skin and fiber, the orange juice is about 210ml. So the cheap orange juice is mainly water, and the original juice is about 5% or 10%. So if you want to drink pure juice, you can squeeze it yourself. Or buy 100% pure juice.
