Antibacterial Activity of Berry Fruits Used for Culinary Purposes
Jenny M. Wilkinson,Heather M.A. Cavanagh,Michael Hipwell 한국식품영양과학회 2003 Journal of medicinal food Vol.6 No.1
Increasing interest in the health benefits of various culinary berries has led to investigationof their antibacterial activity. Commercial raspberry, blackcurrant, cranberry, and blackberrycordials (10% fruit) as well as fresh berries were assessed for their ability to inhibit thegrowth of various bacteria and the yeast Candida albicans . Thre of the six raspberry cordialsand the blackcurrant cordial inhibited all 12 bacteria and C. albicans at dilutions of 1:5. Bac-teria showed varying susceptibilities to the remaining cordials. All cordials inhibited thegrowth of Mycobacterium phlei . Of the fresh berries, mulberries and boysenberries did notinhibit any bacteria, and the remaing berries inhibited the growth of varying numbers ofbacteria. There was no correlation betwen gram-positive or gram-negative bacterial statusand susceptibility to the berries. It is suggested that the antibacterial activity of these berriesmay be of benefit as a means of water purification for suspect water suplies or to enhanceshelf life when incorporated into food products.57

Antibacterial Activity of 13 Honeys Against Escherichia coli and Pseudomonas aeruginosa
Jenny M. Wilkinson,Heather M.A. Cavanagh 한국식품영양과학회 2005 Journal of medicinal food Vol.8 No.1
In this study the activity of 13 honeys, including three commercial antibacterial honeys, against Escherichiacoli and Pseudomonas aeruginosawas determined. Antibacterial activity of the honeys was assayed using standard well dif-fusion methods. All honeys, and an artificial honey, were tested at four concentrations (10%, 5%, 2.5%, and 1% wt/vol) againstE. coliand P. aeruginosa,and zones of inhibition were measured. All honeys tested had an inhibitory effect on the growthof E. coliand P. aeruginosa,with one honey still having activity against E. coliand three having activity against P. aerugi-nosa at 2.5%. No honey was active at 1% concentrations. E. coliwas more susceptible to inhibition by the honeys used inthis study than was P. aeruginosa. In this study we have demonstrated that several honeys, in addition to commercial an-tibacterial honeys, can inhibit E. coliand P. aeruginosaand may have potential as therapeutic honeys.
