Title: Simulated nut product mfr. - by hydrating film-forming substance with water- immiscible fluid and drying mixed dispersion
Inventor: DURST JACK R
IPC: A23L35/00
Filed: 1973-08-24
Abstract: A simulated nut product is manufactured by mixing a film-forming substance with a fluid, immiscible with water, and with water to hydrate the film-forming substance.
