Researchers develop skin repair material from soybean waste product

Phys.org Chemistry reported that researchers have transformed okara, a waste residue generated during the production of tofu and soy based beverages, into a bioactive, biodegradable biomaterial. The material is suitable for 3D printing and could eventually be used to manufacture localized medical devices designed to protect and repair damaged skin. [1]

Okara is created during the processing of soybeans, a crop with global output exceeding 350 million metric tons annually. Brazil produces more than 35 percent of the global supply, while the United States generates around 30 percent and Argentina forms the third major producer. [3]

The conversion of agricultural waste into useful goods forms part of the bioeconomy, which encompasses economic activities that use biological material and biotechnology to create energy, services, and physical products. Researchers intend to continue developing the okara material for future medical application. [1][2]
