After the Qingming Festival, purple and red mulberries, reflecting the spring light, gradually appeared on the market. Mulberries, known as "kidney nourishing fruits", are very popular fruits, whether in various "local flavor live broadcast rooms" or in community group stores. However, there are also many rumors circulating on the internet that "eating too much mulberries can lead to poisoning". What exactly is going on? How to choose edible mulberries? Purchase: Do not buy dyed mulberry trees. China has a history of cultivating mulberry trees for thousands of years. Archaeological research has found that in the late Zhou Dynasty, picking mulberry and raising silkworms were already common agricultural activities. And the sweet and juicy mulberry is a fresh fruit that has been loved by people since ancient times. Mulberry, also known as mulberry, black mulberry, etc., is described in the "Chinese Encyclopedia Dictionary" as "a cluster of juicy single flower berries that form spikes". There are many varieties of mulberry trees. The mulberry trees they bear are black, purple, bright red, white and chartreuse. At present, the main varieties of mulberry sold in the market are purple black. Modern research has shown that mulberry is rich in nutrients, including various essential amino acids, easily absorbed polysaccharides, vitamins, organic acids, carotenoids, anthocyanins, and other nutrients. Regular consumption is beneficial for enhancing immunity, promoting hematopoietic cell growth, and promoting metabolism. The deep trees chirp with doves and mulberries, and the noon breeze brings butterflies and cauliflower yellow. Every April to June, from south to north, numerous fruits gradually hang on the branches of the mulberry tree. How to choose fresh and high-quality mulberries? Xiao Gengsheng, a scientist in the post of mulberry quality evaluation and processing in the national sericulture industry technology system and a researcher in Zhongkai agricultural engineering College, reminded consumers to pay attention to the following points: look at the shape, good mulberry grains are plump and firm, big and thick, with shiny surface, and round or silkworm shape is preferred. On the surface, mature mulberries have an oily texture on their surface. Black mulberries have a bright black color, while red mulberries are as red as fire. At the same time, good mulberry fruit particles are intact and undamaged, and there is no juice leakage. If mulberry is found to have a darker color on the outside and a lighter color on the inside, it is possible that it has been dyed and consumers should purchase it with caution. Eating: Mokuduo mulberry fruit is a type of aggregated berry that has a thin and easily rotting skin, uneven surface, and is difficult to clean when consumed in moderation. Before consumption, rinse repeatedly with flowing water to remove any dust that may have adhered to the surface, and then soak in light salt water or rice washing water for 5 minutes. When soaking, be careful not to remove the mulberry stalks to prevent residual pesticides from entering the interior of the fruit with water. Mulberry is one of the first varieties to be included in the national list of medicinal and food sources, and there is a folk saying of "one mulberry with seven flavors". Mulberry has a high comprehensive utilization value. In addition to fresh consumption, it can also be used as medicine or made into mulberry juice, mulberry paste, mulberry sauce, mulberry wine, dried mulberry, etc. Xiao Gengsheng's team found through animal experiments that the polysaccharides and other components contained in mulberry have a good preventive and protective effect on alcoholic liver injury. In addition to consuming fresh mulberry, consumers can also choose high-quality processed mulberry products based on their own situation. However, although mulberry has a beautiful taste and many advantages, not everyone can enjoy it heartily. Xiao Gengsheng explained that traditional Chinese medicine believes that mulberry is a cold and cool food. People with weak spleen and stomach or cold air in the spleen should not eat too much at once, especially immature mulberry, which has a high acid content and is very beneficial to the intestines and stomach
