Inhibition of Listeria monocytogenes on Hot Dogs Using Antimicrobial Whey Protein‐based Edible Casings

Abstract: Whey protein isolate (WPI) films (pH 5.2) containing p-aminobenzoic acid (PABA) were heat-sealed to form casings. Hot dogs prepared with WPI, collagen, or natural casings were cooked, surface-inoculated to contain 10 3 Listeria monocytogenes CFU/g, and examined for numbers of L. monocytogenes, mesophilic aerobic bacteria (MAB), lactic acid bacteria (LAB), and yeast/mold during 42 d of storage at 4°C. Listeria populations on hot dogs prepared with WPI-1.0%-PABA casings remained relatively unchanged; however, nu… Show more

“…Through these crosslinks, tensile strength of the collagen casing increases to 20 MPa and higher, which is comparable with the reported values in the previous study [39], indicating the effectiveness of these crosslinks. Especially, the higher tensile strength and lower elongation at break in the DHT-treated casing indicated its superiority to other physical treatments for collagen casing production.…”

“…17,18 Antimicrobial packaging reduces the growth rate of specifi c microorganisms by direct contact of the package with the surface of solid foods (meats, cheese, etc.). [19][20][21] In the milk industry, one of the most common problems is post-processing contamination of cheese products. Poor sanitation, unhygienic practices and unsuitable storage can cause growing pathogenic microorganisms to contaminate the surface of the product.…”

“…Antimicrobial packaging can be a promising tool for protecting RTE meat products from Listeria monocytogenes contamination (Janes and others 2002). Recent edible film research has focused on casein, collagen, chitosan, gelatin, soy protein, whey protein, calcium alginate, and methyl cellulose‐based films (Coma and others 2002; Cagri and others 2003). These edible films can be used as carriers for antimicrobials.…”
