Abstract:
A compound inhibitory to lactic acid bacteria was isolated from green Manzanillo olives. The inhibitor is a phenolic compound, is devoid of acid-hydrolyzable reducing sugar, and has a bitter taste. Freezing the olives prior to extraction caused chemical changes which greatly increased the level of the inhibitor, whereas heating prior to freezing prevented its formation.
