This study investigated the isoflavone content and textural properties of tofu prepared from Himalayan black soybeans (Glycine max (L) Merrill). Two separate techniques were used to produce soymilk from soaked Himalayan black soybean seeds. The soymilk was then curdled using ten different coagulants, both natural and synthetic. Analysis of isoflavone levels in the tofu samples showed that tofu prepared using Rhododendron arboreum floral juice using both methods showed the highest total isoflavone content. Regardless of the soymilk preparation technique, tofu coagulated with acetic acid displayed the best textural quality.
