Adj. 1. precooked - cooked partially or completely beforehand; "frozen precooked meals from the supermarket" ready-to-eat chicken products to protect against pathogenic L. monocytogenes. Zein zein the principal protein in maize. Has low nutritive value, being deficient in lysine and tryptophan. film is effective against the bacterium on ready-to-eat chicken when it is combined with bacteriocins. Investigators added nisin nisin an antibiotic substance isolated from cultures of lactic acid producing streptococci and reputed to have antibacterial activity against gram-positive bacteria. to the zein edible film to enhance its effectiveness. For example, chicken may be covered with a transparent colorless film that is carrying a bacteriocin bacteriocin /bac·te·rio·cin/ (bac-ter´e-o?-sin) any of a group of substances, e.g., colicin, released by certain bacteria that kill other strains of bacteria by inducing metabolic block. . The idea would be to prevent post-processing recontamination of cooked foods. Putting calcium propionate with the nisin reduces levels of bacteria to nondetectable levels sooner. The calcium propionate enhances the activities of nisin. Contact: Michael Johnson, University of Arkansas, Department of Food Science, 272 Young Ave., Fayetteville, AR 72704. Phone: 501-575-4605.
