The Fascinating Uses of Silkworms

In the vast river of human history and civilization, a seemingly inconspicuous yet indispensable entity exists the silkworm. While commonly associated with silk, this remarkable creature possesses equally astounding applications in various industries. In this post, we invite you to delve deeper into the extraordinary world of silkworms, transcending your conventional notions and uncovering their remarkable versatility.

Silkworms in the Textile Industry

The textile industry and silkworms are inseparable. people nourish domestic silkworms with mulberry leaves. They extrude a long silk thread when they mature, enveloping themselves to create an optimal environment for their transformation into moths. This silk thread serves as the raw material for crafting silk fabrics.

The silk thread emitted by silkworms is abundant in proteins, and the resulting silk fabrics provide a delightful tactile experience. They are smooth, soft, and hypoallergenic, constituting a luxurious fabric with a shimmering sheen and exceptional drape. Across ancient times and in contemporary society, silk has been widely sought after and cherished for its outstanding qualities. 

Presently, silk showcases remarkable versatility in the crafting of upscale clothing, home decor, and adornments. Thanks to advancements in science and technology, silk fabric is no longer confined to traditional constraints, leading to the emergence of diverse variants such as silk blends.

Beyond its role in fabric production, you might be intrigued to discover that silkworms also contribute to the art of dyeing. Silkworm excrement, referred to as “silkworm sand,” can be extracted using ethanol and utilized as a dye for silk fabric, achieving an impressive color fastness level of up to 4. If this intrigues you, why not give it a try yourself?

Silkworms in Food and Medicine

Food Value of Silkworms

Silkworms also have significant value in food applications. Before they transform into moths, silkworms pass through a stage known as the pupa, which is referred to as silkworm pupae.

In East Asia, silkworm pupae are highly esteemed for their exceptional nutritional value. They are rich in proteins (51% crude protein in fresh silkworm pupae), fatty acids (29% crude fat), and vitamins (including vitamin A, vitamin B2, vitamin D, and ergosterol), among others.

The protein content in silkworm pupae is notably higher than that in typical foods. It is approximately twice that of pork, four times that of eggs, and ten times that of milk.

Silkworm pupae contain a complete range of essential amino acids to maintain nutritional balance in the human body. They represent a high-quality insect protein. Whether stewed, stir-fried, fried, used in soups, or soaked in alcohol, they provide significant benefits to the human body.

Medicinal Value of Silkworms

Whether in ancient classics like the “ Compendium of Materia Medica” or in modern books such as the “Chinese Materia Medica Dictionary,” the “National Compilation of Chinese Herbal Medicine,” and the “ Chinese Materia Medica,” various forms of silkworms are documented as medicinal and have the potential to treat a variety of diseases.

The eggshells left after silkworms hatch were used to treat toothaches, reduce swelling, and relieve a sore throat. The shed skin of silkworm larvae was believed to be effective in treating dysentery, vomiting blood, and hematochezia. The dried feces of silkworm larvae can have therapeutic effects in treating rheumatic pain, itching caused by rubella, headaches, and other ailments.

Silkworm pupae were used to help produce saliva and slake thirst, aid digestion, and treat fever and roundworm infections. Silkworm cocoons were believed to possess heat-clearing and hemostatic properties, as well as detoxifying and wound-healing effects.

Modern research has shown that the oil extracted from silkworm pupae, appearing as a yellow to red transparent liquid, has certain effects in treating hypertension, high cholesterol, fatty liver, and hyperlipidemia.

Silkworms in Scientific Research

Biological Research

Silkworms undergo four distinct stages in their life cycle and are easy to rear, making them important model organisms. They hold significant scientific importance in the fields of insect physiology, developmental biology, genetics, and pest control.

Through research, many important achievements have been made. For instance, scientists utilize new bioinformatics algorithms to predict the full length and number of genes in domestic silkworms, enabling a better understanding of domestication mechanisms within species through phylogenetic analysis. By comparing spider silk and silkworm silk, researchers propose genetic recombination as a means to modify silkworm silk and create fibers with different properties.

Medicine Research

Silkworms’ organs and tissues, such as the brain, heart, nervous system, and muscles, are similar to those of humans, making them valuable in studying human physiology, disease, genetics, and the development of new drugs. Silkworms offer cost-effective and rapid results due to the smaller scale of experiments.

Researchers have conducted numerous studies using silkworms and achieved remarkable results, including assessing drug safety and efficacy. Additionally, they’ve infected silkworms with various pathogens to comprehend infection mechanisms and devise potential treatment strategies. These investigations have unveiled the intricate interactions between hosts and pathogens, hastening the discovery of new antibiotics.

Silkworms with Rural Community Economy

Empowered by the promotion of the collective economy in rural China, silkworms have played pivotal in the development of various industries, thereby benefiting local communities. Raising silkworms serves as a significant livelihood for many farmers and communities, offering numerous employment opportunities. 

Silkworm rearing boasts a short cycle, ensuring quick results and every growing stage of the silkworm holds value, guaranteeing a steady market demand. Silkworms can be raised throughout the year, providing an additional source of income and fostering agricultural diversification, thereby reducing dependence on a single crop. Integration with other agricultural activities allows for the optimization of resources.

Concurrently, silkworm rearing propels the development of related industries in the surrounding areas. People can utilize the silk produced by silkworms to craft various products such as accessories, clothing, and traditional crafts. 

This, in turn, contributes to the growth of tourism, with silk-related places and activities becoming highlights. Not only does this create more employment opportunities for local residents, but it also enables visitors to gain deeper insights into the traditional techniques and cultural significance associated with silkworms and silk.

Summary

Silkworms are a precious resource, and their versatility attracts people to explore their potential further and utilize their various characteristics to enhance various fields. Now that you have gained an understanding of the secrets behind this extraordinary creature, it will help you unlock the door to more possibilities and applications.
