The body of the silkworm changes color. The pigment addition method can change the coloring performance of silkworm silk glands by adding different colors of dye pigments, and different colors of silkworm cocoons can be obtained. From the second day after the 5th instar of the silkworm to the time before the silkworm, each box of silkworm seeds needs to use 1 bag of pigment powder, and add the leaves sprayed with pigment dilution twice a day in the morning and evening.
Pour 1 bag of pigment powder into a 10-liter plastic bucket, add an appropriate amount of about 45 warm boiled water to dissolve into a pigment stock solution, and then prepare a pigment dilution solution with cold boiled water at 1 5, spray it directly and evenly on the leaves, and require it to be turned over while spraying, generally 1 kg of pigment dilution can be sprayed with 10 kg of leaves, so that the mulberry leaves can be directly used to feed silkworms after spraying. The solution immersion method soaks the silkworm body in pigments and dyes, so that the pigment enters the silkworm body through the valve, passes through the blood and reaches the silk gland, and finally produces a color cocoon. Specifically, it is to soak the 4 sleeping silkworms in the aqueous solution of oxide heavy salt (or diazonium salt of astraquinone, sulfur indigo, or diazonium salt of sulfur dye) of copper phthalocyanine blue (or green) 5 times, once every 8 hours, 3 seconds each time.
The pigment added by the pigment method is food coloring, so theoretically it is edible, and there is no excessive impact on the silkworm silk, and the natural color silk is firmer than the later dyeing, and the yield of color cocoons is much less than that of normal color cocoons. As for how to distinguish between natural and dyed colored silk, no information has been found. For more information.

Look at the strains of colored silkworm cocoons. Generally speaking, the color cocoons that are not artificially fed with pigments are all natural colored silkworm strains, and the color of the silkworm baby itself will not be colored, but the content of pigment in its blood and the ability of pigment to transport to the silk glands are different.
-
Yes, there is. Colored silkworms. To use special feed.
Special mulberry leaf is the latest scientific research achievement developed by the Sericulture Research Institute after years of research and innovation by introducing and absorbing the latest scientific research achievements at home and abroad. It has a high level of knowledge, popularization and interest. There is also a state-of-the-art sausage-based artificial feed.
You can go to the following to take a look at the knowledge of related aspects.
-
Of course, there are natural colored cocoons that eat mulberry leaves, so I raised them, red, golden, and green (it looks more like pale yellow), and I don't know about other colors.
-
Yes, yellow, green, white, and pink.

Colored silkworm cocoons are formed by colored silkworms forming pupa.
Color pupae, the use of sausage-type artificial feed (without mulberry leaves) and color silkworms, color cocoon technology, through the breeding of "science silkworm baby", can completely observe the growth and development of Huiheng to silkworms, silk, cocooning, pupation, moth, oviposition and other silkworm baby life process. It is the Sericulture Research Institute that introduces and absorbs the latest scientific research achievements at home and abroad, and develops the latest scientific research achievements after years of research and innovation.

Colored silkworm cocoons are formed by colored silkworms forming pupa. Color pupa using sausage artificial feed (without mulberry leaves) and color silkworms, color cocoon technology, through the breeding of "science silkworm baby", can be completely observed silkworm growth and development, silk, cocooning, pupation, moth, oviposition and other silkworm baby life process. It is the Sericulture Research Institute that introduces and absorbs the latest scientific research achievements at home and abroad, and develops the latest scientific research achievements developed after years of research and innovation.
Silkworm farming is technically similar to that of ordinary silkworm farming, but the disease resistance of silkworms is relatively strong, and it can adapt even if the weather changes a little. In the spring of 2011, Tongliang County took the lead in raising 6 colored silkworms in Damiao Town, harvesting more than 200 kilograms of orange color cocoons to make natural colored silk quilts, which were well received by consumers.
Colored silkworm cocoons are made by transforming the genes of silkworms, so that silkworms spit out colorful silk in various colors, such as orange, pink, light yellow, light green, and rust. The color of the silkworm cocoon extracted from the natural color silk is soft and gorgeous, the use of this pure natural nuclear touch trembling color silk to make textiles, like natural color cotton as environmentally friendly and non-decolorized, eliminating the printing and dyeing process, reducing the pollution of silk printing and dyeing, can avoid the harm of various chemical residues in the fabric processing to the human body, the product is favored by high-end consumers at home and abroad, and has strong competitiveness in the market.
The colored silkworm is not a new species, but it is only the appearance of scientific and technological feeding of silkworms. The life of a silkworm goes through four different stages, egg, larva, pupa and adult. Silkworms overwinter with eggs, hatch into larvae when mulberry trees germinate in spring, the larvae eat mulberry and grow, sleep and molt after 4 days, and begin to form cocoons in about 25 days.
After two days, the silking is completed, and then after 2-3 days, the skin is molted and pupated in the cocoon. The pupal turns into an adult worm after about 10 days, which is a silkworm moth. Male and female moths mate to lay eggs and then die.

Medicinal value of silkworm cocoon:
From the "Compendium of Materia Medica": silkworm cocoons, prescription books are multi-purpose, and the various Materia Medica does not speak, and there is a lack of text. In modern times, carbuncles were used to replace needles, and one head was used to produce one head, and two pieces to produce two heads.
Boiling soup to quench thirst is very famous in ancient times. Danxi Zhu said that this thing can relieve the fire in the bladder and lead the clear qi to the mouth, so it can quench thirst.
Pharmacological effects: The cocoon of silkworm moth has cholinergic effect. The 90% ethanol extract of silkworm cocoons treated with petroleum ether, ether and chloroform showed cholinergic effects on blood pressure in anesthetized cats, poor limb guinea pig ileum and rabbit duodenum. However, on frog rectus abdominis specimens, there is no effect on striated muscle.
Medicinal herbs: oblong-oval, or slightly constricted in the middle, about 3 4 cm long, cm in diameter, white on the surface, with irregular wrinkles, and attached silk, fluffy. The silk pattern on its inner wall is very regular.
Lightweight and tough, not easy to tear. The cocoon is not feathered, with 1 yellow-brown silkworm pupae and a light brown and shrunken silkworm skin that is taken off before the pupation is made.

Silkworm cocoon processingThe silk making process of silk includes cocoon mixing, cocoon peeling, cocoon selection, cocoon boiling, silk reeling, reshaking, finishing, inspection and other processes.
It is one of the important processes of silk making. Using the action of water and heat, sometimes adding chemical additives, the sericin on the periphery of the cocoon silk is properly expanded and softened. The adhesive force between the cocoon silk is less than the wetting strength of the cocoon silk, so that the cocoon silk can be continuously dissociated in sequence when the silk is reeled.
There are few insoluble substances in the composition of mulberry cocoon sericin, which is easy to dissolve, swelling and soft in hot water.
