Abstract: An apparatus for electroelution isolation of biomolecules and recovering biomolecules after elution including a tubular enclosure for engaging a piece of separating gel having a band of biomolecules. The enclosure is capped by a closure means having a passage means, and then placed in an electrophoresis tank with the closure means facing the positive terminal. Applying an electric current forces the biomolecules to accumulate at the closure means. The biomolecules may be recovered by inserting a capillary tip through the passage means and drawing the biomolecules through the capillary.

Abstract: Garlic essence is produced by extracting garlic with ethanol and deodorized with phytic acid, added either during or after the extracting step. The garlic essence exhibits outstanding antibacterial action when added to or sprayed onto foods. It is used alone or in combination with .epsilon.-polylysine in the amount of 1-256 .mu.g/ml.
