Abstract: Disclosed is a novel process for the preparation of novel raw material for functional foods containing bioactive materials, comprising activating the enzymes of edible plant seeds at a temperature of 10-35° C. for a period of 5-72 hours with oxygen and water until reaching the maximum nutritional value of the seeds, then the seeds together with their sprouts are treated in the aqueous solution or suspension or emulsion of physiologically or dietetically advantageous materials between 60-100° C. for a period of 10-180 minutes, and then the raw material containing the physiologically important biological materials in this enhanced concentration is separated, dried, optionally chopped and packed. The invention also relates to the products of the novel preparation process and their use.

Abstract: A process for determining the soundness, and the soundness-dependent germinative ability of sowing seeds is based on detecting the characteristic difference between the acoustic excitation response functions of right and damaged seeds. The seeds are excited by their impinging on a hard surface and produce an acoustic signal and by examining the response functions a comparison is performed to decide whether the seeds are right or damaged. Apparatus for carrying out the process includes a feed tank (1), a seed feeding mechanism, a sensing chamber (4) and a vibration sensor (5) for detecting acoustic signals within the chamber (4), the output of the vibration sensor (5) being connected to a signal processing unit (6).
