Red heart kiwi and green heart kiwi which is better
Kiwifruit, also known as kiwifruit, is known as the “king of fruits†for its unique flavor and rich nutritional value. Kiwifruit is divided into green heart kiwi, red heart kiwi and yellow heart kiwi. Among them, green heart kiwifruit is the most common, and it has been “monopolizing†the world kiwifruit market in the past few decades. But in recent years, red heart kiwifruit has been more popular with consumers. So, is the red heart kiwifruit more nutritious than the green heart kiwi? What is the difference between red heart kiwi and green heart kiwi?
Why is red heart kiwi red?
Red heart kiwi is a variant of red meat kiwi, a fruit for both medicine and food. The reason why the red heart kiwi is red is mainly because it contains higher anthocyanins than green kiwi and yellow kiwi. The anthocyanin content is affected by external factors such as soil, light and temperature. Studies have found that the content of anthocyanin in kiwifruit grown in soil with less nitrogen nutrition and higher altitude will increase the color of red kiwi fruit. Conversely, a low altitude or warm climate will reduce the anthocyanin content and the red color will become lighter.
The difference between red heart kiwi and green heart kiwi
1, nutritional value
Red heart kiwifruit is many times more nutritious than ordinary green kiwi. We all know that kiwifruit is rich in vitamin C, but the content of vitamin C in different colors of kiwifruit is different. It has been determined that green heart kiwifruit contains about 74 mg of vitamin C per 100 g, while red heart kiwifruit contains 100 to 410 mg of vitamin C per 100 g. At the same time, the test results also showed that the content of flavonoid polyphenols and dietary fiber of red heart kiwifruit was also higher than that of green heart.
2, peel
Green Heart Kiwifruit is the most primitive kiwifruit variety, with a layer of fluff on the skin, while the reddish kiwi skin is smooth and hairless.
3, taste
Green Heart Kiwifruit has low sweetness and high acidity. Even if it is mature, it is sour. The sweetness of red heart kiwifruit is the highest among the three colors of kiwifruit. Basically, it does not feel sour, so children and old people like it, and some people may feel a little tired.
4, the head
From the appearance, the green heart kiwi is bigger than the red heart, but the weight is similar.
5, the price
China is the country of origin of green heart kiwifruit, which is also common in the market, so the price is not high. The red heart kiwifruit is a new variety, the planting environment and management difficulty is relatively high, and the planting scale is not large, so the price is more expensive than the green heart. At present, the main producing areas of the red heart kiwifruit are Sichuan Cangxi, Sichuan Pujiang, Shaanxi Meixian, Zhejiang é‚Chang and other places.
In general, although the price of red heart kiwifruit is more expensive than that of green heart kiwi, the flesh is brightly colored, high in sugar content, extremely low in acidity, rich in aroma and good in taste, so it is more popular among the public.
