Why is the apple sour? 1. Malic acid is not mature enough. Many apples taste sour because they are not mature enough, because there are about 5% malic acid in immature apples, but these malic acids will ferment with the maturity of apples and slowly transform into various sugars, that is, after the apples are fully mature, the acidity will weaken and become sour and sweet. So, malic acid proves it.
2. Apple is sour because of its high acid content. Another important reason for malic acid is its high acid content. These natural acids are an important part of apple nutrients, which can regulate the secretion of gastric acid and have obvious help to human digestion. However, when the apple is fully ripe, some acidic components will be converted into sugar, thus weakening its acidity.
Malic acid is caused by the substance it contains. Although apple tastes a little sour, it is an alkaline fruit, which is good for human health. After the acidic components in apples enter the human body, they will naturally transform into substances beneficial to the human body, especially after oxidation, they will become alkaline components beneficial to the human body. So apples taste slightly sour and are harmless to human body. On the contrary, there are many benefits.
How to eat apples is the fastest way to lose weight 1, and only eat apples for three consecutive days without eating other fruits and food.
You can eat apples according to the time of three meals, or you can eat them when you are hungry until you are full.
3, preferably red apples. Green apples are sour, for fear of irritating the stomach.
4, apples should be eaten fresh, washed and peeled to avoid pesticide residues.
Your stomach will be very sensitive during weight loss, so avoid drinking caffeinated drinks, such as black tea, coffee, green tea and oolong tea. To avoid stomach upset.
Is apple an acidic food? Apples are weakly alkaline foods.
Although fruit contains all kinds of organic acids, it tastes very sour, but most of it is oxidized into alkaline food after digestion. However, strawberry has organic acids (benzoic acid and oxalic acid) that cannot be oxidized and metabolized, which will increase the acidity of body fluids. They are all acidic foods, with one exception. The main organic acids in vegetables are malic acid, citric acid, tartaric acid and oxalic acid. Here we should pay special attention to oxalic acid, its organism is not easy to oxidize, and calcium oxalate formed with calcium salt is insoluble in water and accumulates in the kidney, which affects the absorption of calcium. Among vegetables, tomatoes, potatoes and spinach all contain oxalic acid. In theory, alkalosis can also occur, but alkalosis is not common in humans, because humans have a lot of stomach acid to neutralize.
