What kind of dates are more delicious? What kind of dates are more delicious? People often say "crooked melons crack dates". Many people think that a bad-looking date must be very sweet. Is that really the case?
Testing this statement is very simple. By measuring their sugar, we can find out who is sweeter, the normal-looking jujube or the abnormal-looking jujube. In food chemistry, some sugars are optically active, that is, solutions. Dissolve sugar in water, and then we can measure its optical rotation. Through the difference of optical rotation, we can infer its approximate sugar content. It can be determined by hand-held sugar meter.
After measuring with hand-held sugar meter, we found that the sugar content of fresh jujube was 6.7%, and that of "Guagua Cracked Fruit Jujube" was 6.5%. Except for the experimental error, there is little difference in sugar content between fresh jujube and "Guagua Cracked Fruit Jujube". Who is not suitable for eating dates? Fresh jujube contains a lot of vitamins, which is beneficial to people who often eat it, but it will be uncomfortable to eat too much. Dried dates are tonics, and many people think they should eat more. Therefore, when people are sick or weak, they will choose to eat more dates to supplement their health, but this is actually a wrong view.
Because jujube contains high dietary fiber, especially on jujube skin, it is a test for our digestive function, so people with poor digestive function and weak spleen and stomach should not eat too much jujube, especially raw jujube, otherwise it may lead to indigestion symptoms. The water content in dried jujube is very, very small, and there are many dietary fibers, which can easily burden the stomach. When I am sick, I am already very weak, and my stomach will feel even worse. But it is very beneficial for healthy people to eat a jujube every day. How to eat jujube is easier to digest. According to experts, boiling water can soften the indigestible fiber in jujube, so that the treated jujube will be eaten in our stomach, and the stomach will not be so uncomfortable. However, because jujube is rich in vitamins, the blanching time should not be too long, and 15 seconds is enough, otherwise the loss will outweigh the gain. This method is also suitable for dried dates. Whether the nutritional value of fresh jujube and dried jujube is different. Professor Tong Qigen introduced that according to the experimental results, the vitamin content of fresh jujube is about 250 mg per 100 g, while that of dried jujube is only a dozen mg, a difference of about 15 times. In other words, if you want to get more vitamins, eat fresh dates.
As the saying goes, "eat jujube to replenish blood", jujube contains a lot of mineral iron, so what is the difference between the mineral iron content in fresh jujube and dried jujube? Professor Tong Qigen said that trace elements such as iron, zinc and calcium will not be lost with any environmental changes. Fresh jujube has more water, while dry jujube has less water, which is equivalent to concentration, so there must be more trace elements in dry jujube than fresh jujube. If you eat dates to replenish blood and minerals, choose dried dates.
