Abstract
The disclosure relates to systems and methods for improving the manufacturing of silk solutions and powders containing silk fibroin obtained from silkworm cocoons. The methods include use of a reactor vessel to degum, rinse, and dissolve the silk fibroin protein from silk inputs to obtain a food grade silk powder. The reactor vessel may include a combination of inputs and outputs for introducing and removing different components used or generated during the process. The systems may include any combination of heat exchangers, holding tanks, filtration modules, and post-treatment equipment as necessary to obtain the silk powder. The solutions and powders can be used to improve the post-harvest preservation of perishables and to improve the performance of packaging, including biodegradable packaging.
