Silkworm pupae are generally fresh, and can be eaten all over after washing, drying and pickling.
The animal protein content in cicada pupa is rich, which is suitable for people with low protein.
What are the nutritional values of cicada pupa? Cicada pupa is known as the "king of protein". The content of protein is about 68 grams per 100 grams, which is about 6 times that of eggs, so it is abundant. However, abundant content does not mean high nutritional value. Because the nutritional value of food protein mainly depends on the type, quantity and structural proportion of amino acids it contains.
After testing, cicada pupa contains 17 kinds of amino acids, and the total amino acid content reaches about 63%. However, tryptophan and methionine (both essential amino acids for human body) are low in cicada pupa, and belong to the restrictive amino acids of cicada pupa, which leads to the fact that other essential amino acids cannot be fully absorbed and utilized by human body, which greatly reduces the nutritional value of protein.
At present, the cicada pupa has been determined to contain polyphenols and flavonoids, which have certain effects of antioxidation, improving immunity and delaying aging. The cicada pupa also contains 9 kinds of minerals necessary for human body, such as iron, zinc and manganese, among which the iron content is the highest, but the ratio of iron and zinc is not suitable, which may interact and affect the absorption effect. Except for the high content of iron, manganese and zinc, the content of other minerals in cicada pupa is low, which can not be used as the main food source to supplement these minerals.
Precautions for eating cicada nymphs usually live underground for 3-5 years, and there are probably parasites, heavy metals and other substances harmful to human body in their bodies. Therefore, when eating, the necessary treatment must not be omitted.
wash
Soak in clear water properly, and thoroughly remove the dirt on the surface, especially the gaps between abdominal sections, because there may be parasites, bacteria and so on. In addition, it is best to boil it with hot water before cooking, cool it and cut it to remove the internal organs.
