Are oranges acidic or alkaline, and are oranges acidic or alkaline?

What is acid-alkaline foodThe so-called acid-alkaline food does not refer to the taste of food, but refers to the fact that after food enters the digestive system, it undergoes oxidative decomposition, some produce alkaline substances, and some produce acidic substances.

Oranges should be alkaline foods. Oranges are dry, and after eating more, it is easy to make people "on fire". Although fruits are generally mostly alkaline, some are acidic, such as plums, apricots, plums, strawberries, etc., which contain cinchin acid, benzoin acid and oxalic acid.

These acids are not easily oxidized and decomposed in the human body, and the products formed after metabolism are still acidic substances, and excessive consumption can make people's acid-base balance imbalanced, and may even cause acidosis.

Oranges are rich in potassium and are alkaline foods. Tangerines are highly nutritious, and eating tangerines has many benefits for the human body. For example:

1.Tangerines are rich in vitamin C, which has the effect of beautifying and anti-aging. 2.

Tangerines are rich in citric acid, which has an anti-fatigue effect. 3.The thin peel on the inside of the orange peel contains dietary fiber and pectin, which can promote laxative and lower cholesterol.

The flesh, skin, core, vein, and leaves of oranges can all be used in medicine. Tangerine peel, also known as tangerine peel, is one of the important medicinal materials. Although the taste of oranges is sour, but it is actually an alkaline food, oranges are very rich in nutrients, not only rich in fructose, but also contain a lot of vitamins, but also contain calcium, potassium and other minerals, a large number of vitamins help to improve the body's immunity.

At the same time, it can also scavenge oxygen free radicals, and the thin skin inside the orange peel also contains dietary fiber and pectin, which has a certain laxative effect. And the flesh and skin of oranges can be used in medicine.

Tangerines are alkaline. The acidity or alkalinity of a food is not determined by its taste, but by whether the substance produced by the digestion of the food is alkaline or acidic. Most of the fruits eaten are basically alkaline fruits, except for plums, strawberries and lemons.

Alkaline foods:Alkaline food refers to the chemical composition of the ash obtained by the combustion of food, which mainly contains potassium, sodium, calcium, magnesium and other elements, which are dissolved in water to form alkaline solution, such foods include various vegetables, fruits, beans, milk and almonds, chestnuts and so on in hard fruits.

In a healthy state, the human body is generally not affected by the effects of food intake that causes changes in acidity and alkalinity. Many expressions of "food acidity and alkalinity" are actually confusing "ash after food burning" with "products metabolized by food in the body".

1. Oranges are alkaline foods. The acidity and alkalinity of food is determined by the taste of the food, but by the products produced after the food enters the human body and undergoes metabolism.

2. Except for oranges, all fresh fruits and vegetables are alkaline foods. The pH value of the orange itself is less than 7, which is acidic, but when the orange enters the human body, it will increase the content of potassium and sodium in the body to produce the corresponding alkali, and most of the organic acids contained in the orange itself have been broken down in the gastrointestinal tract.

1. Oranges are alkaline foods.

The pH of oranges is less than 7 and is acidic, but it is recognized as an alkaline food. Because when it enters the human body, it adds K and Na plasma to the human body to generate the corresponding alkali, and most of the organic acids, such as citric acid, are decomposed, and the pH of the human body will rise. So we generally call oranges an alkaline food.

Second, the introduction of oranges.

1. Orange is bright in color, sweet and sour, generally orange yellow, is one of the most common fruits in people's lives, and the peel can be used in medicine.

2. Oranges are sweet and sour, warm and enter the lungs. It mainly treats chest septum gas, vomiting and lack of food, thirst in the mouth, pulmonary fever and cough and excessive drinking. It has the effect of appetizing, quenching thirst and moisturizing the lungs.

Tangerines are also very nutritious, and one orange can almost meet the vitamin C content required by the human body in a day. In addition, oranges contain more than 170 plant compounds and more than 60 flavonoids, most of which are natural antioxidants.

3. The nutrients in oranges have the effects of lowering blood lipids and anti-atherosclerosis, which are beneficial to prevent the occurrence of cardiovascular diseases. Tangerine juice contains a substance called nomiline, which has the ability to inhibit and kill cancer cells, and has a preventive effect on stomach cancer. The orange peel is orange-red in color, and the flesh is grainy, very similar to that of grapefruit.

The orange peel is thin and fleshy, the juice is sweet and sour, and the orange water can overflow when you peel it.

Tangerines are acidic fruits.

Acidity and alkalinity refer to the acidic and alkaline properties of a substance in an aqueous solution, which is usually expressed in terms of pH. The pH range is between 0 and 14, where 7 is neutral, less than 7 is acidic, and more than 7 is alkaline. Acidic species have the ability to release hydrogen ions (H+), while alkaline substances have the ability to release hydroxide ions (OH-).

The presence of these two ions makes the aqueous solution acidic or alkaline.

For oranges, the main components it contains are organic acids such as water, fructose, glucose, citric acid, and mineral elements such as potassium, calcium, and magnesium. These ingredients give tangerines their acidic character. Citric acid is a common organic acid, and its presence makes the pH of oranges around the same level, in the acidic range.

Therefore, tangerines can be considered as acidic fruits.

Things to pay attention to when eating oranges

Acidic fruits refer to fruits that contain a lot of organic acids, such as lemons, oranges, strawberries, etc. The nutritional value of oranges is very high, it is rich in vitamin C, carotene, dietary fiber and other nutrients. Among them, vitamin C is a powerful antioxidant that can help the body resist viruses and prevent many diseases.

Although tangerines are acidic fruits, it doesn't mean that we can't eat them. In fact, moderate intake of acidic fruits is very important for maintaining human health. A reasonable diet and proper intake of acidic fruits are very beneficial for maintaining good health.

It is important to note that for some populations, excessive intake of acidic fruits may adversely affect physical health.

Oranges are alkaline foods. Because when oranges enter the human body, they add K+ and Na+ plasma to the human body to generate the corresponding alkali, and most of the organic acids, such as citric acid, are decomposed, and the pH of the human body will increase, so we generally call oranges alkaline food.

The acidity and alkalinity of a substance is mainly determined by the type and content of minerals contained in food.

The environment in which oranges are grown.

Oranges are grown in the middle and lower reaches of the Yangtze River and in areas south of the Yangtze River, and some are also cultivated in areas south of the Qinling Mountains.

Oranges prefer to grow in a warm and humid environment, but they are not tolerant to a certain amount of cold, and prefer to grow in deep and fertile loam soils, and the growth will slow down when the temperature is below -5 degrees.

It is planted in Zhejiang, Fujian, Hunan, Sichuan, Guangxi, Hubei, Guangdong, Jiangxi, Chongqing and other places.
