Nutritional value of ugly apples
Apple has the reputation of "wisdom fruit" and "memory fruit". People have long found that eating more apples can improve memory and intelligence. Apples are not only rich in essential nutrients such as sugar, vitamins and minerals, but also rich in zinc. According to research, zinc is a component of many important enzymes in human body, and it is a key element to promote growth and development. Zinc is also an essential element for nucleic acid and protein, which is closely related to memory. Zinc is also closely related to producing antibodies and improving human immunity. The water content in fresh apples is 85%. Apple contains polyphenols and flavonoids, natural chemical antioxidants and a lot of crude fiber. It contains more potassium, which can combine with excess sodium salt in human body and excrete it. When the human body consumes too much sodium salt, eating some apples is beneficial to balance the electrolyte in the body.
Characteristics of ugly apples
Ugly apples actually have another name, rock candy heart apples, so they are both the same variety, and the most intuitive difference from ordinary apples is sugar heart. The so-called sugar core is a phenomenon of sugar precipitation caused by temperature difference. The sweetness of the sugar core is higher than that of the sugar core, and the sugar core will have a hint of fruit acid, which is weak, but the fine products can be tasted. In addition, if you eat it with skin, the candy heart will melt into slag, and the ugly apple will leave apple residue, which means that the skin of the ugly apple is really a little thicker. The ugly apple is not only rough in surface and dark in color, but also full of pockmarked spots on its "face". As a whole, it looks like the frozen face of children in the north in winter. Although it looks ugly, the ugly apple tastes really sweet, and the sweetness of the pulp near the peel is as high as 16+. The whole apple tastes sweet, crisp and juicy. Not only that, compared with ordinary apples, ugly apples have more tender flesh, and the nine words of thin skin and tender meat, rich juice and sweet crispness can well summarize the characteristics of ugly apples.
The heat of ugly apples
Apple is a low-calorie food, which produces about 60 kilocalories per100g. Apple belongs to Malus of Rosaceae, and its trees are deciduous trees. Apple has high nutritional value, rich in minerals and vitamins, and rich in calcium, which helps to metabolize excess salt in the body. Malic acid can metabolize calories and prevent obesity in the lower body. Apple is known as "living water" because of its high solubility and easy absorption by human body. It is beneficial to dissolve sulfur and make skin smooth and tender. Research by Hirosaki University in Japan confirmed that polyphenols in apples can inhibit the proliferation of cancer cells. A study in Finland is even more exciting: flavonoids contained in apples are an efficient antioxidant, which is not only the best blood vessel cleaner, but also the bane of cancer. Apples contain mineral elements boron and manganese that can strengthen bones. A study in the United States found that boron can greatly increase the concentration of estrogen and other compounds in the blood, which can effectively prevent calcium loss.
Is the ugly apple crisp or flat?
Ugly apples are crisp apples, because they grow in the natural environment, and their surfaces have experienced many vicissitudes, showing a very ugly feeling. However, they are famous for their sweet taste, crispness and juiciness, and people who have eaten them are full of praise for them. The surface of ugly apples will not be waxed, so they can be eaten after being washed with clear water, and they smell with the unique aroma of apples. There is actually no significant difference in appearance between pink apples and crisp apples. The color of the peel is mainly determined by the synthetic content of anthocyanins, and there is no way to distinguish between pink apples and crisp apples from the appearance alone.
