Plum extract.(In brief ...)
As little as 3% of plum extract mixed in raw meat is more than 90%
effective in suppressing the growth of major foodborne pathogens such as
E. coli O157:H7, Salmonella, Listeria, Y. enterocolitica . . .
Chlorine dioxide has antibacterial effect on
Salmonella--contaminated eggs.
Chlorine dioxide is an antimicrobial pesticide recognized for its
disinfectant properties since the early 1900s. It kills microorganisms
by disrupting the transport of nutrients across the cell . . .
Try spraying ozone to reduce Listeria levels on raw salmon
fillets.
Ensuring the microbial safety and quality of seafood products is a
major challenge. Strong oxidants, such as ozone, may prove efficacious
as antimicrobial treatments. But ozonation may also promote . . .
Washing apples.(In Brief ...)
Washing apples can reduce the number of organisms on an
apple's surface. Even a plain-water wash can reduce microbial
counts by 90% or more. Adding a sanitizer or cleaner to the wash water
can . . .
Electrolyzed oxidized water sanitizes fresh chicken.
Electrolysis is a water treatment process that produces two forms
of altered water: a reduced or alkaline (high-pH) water, and an oxidized
or acidic (low-pH) water. The electrolysis process . . .
Plastic film type does not significantly influence effectiveness,
stability of nisin coatings.
L. monocytogenes has been responsible for numerous outbreaks and
recalls particularly associated with post-processing contamination of
ready-to-eat (RTE) foods. In conjunction with good . . .
Microwaves sterilize sliced beef in gravy.
Microwave heating is a form of dielectric and volumetric heating
which potentially can heat food products more rapidly and uniformly than
conventional retort processes. Advanced microwave . . .
Use enzyme--treated dairy powders to inhibit the growth of
food--associated microorganisms.
A number of milk components, such as lactoferrin, lactoperoxidase
and fatty acids, are known to possess antimicrobial activity. Milks of
different species contain different amounts of antimicrobial . . .
A web-based software.(In Brief ...)
Intellipur, a web-based software, allows water, food storage and
transport managers to actively monitor and control the safety and
quality of processed water and food in cold storage rooms, . . .
Develop an integrated model for heat transfer, dynamic growth of
S. enteritidis in shell eggs.
Shell eggs are the leading cause of salmonellosis associated with
S. enteritidis. To deal with this concern, researchers need complete
growth data on S. enteritidis in eggs and a heat transfer . . .
Antimicrobial activity.(In brief ...)
The antimicrobial activity of allyl isothiocyanate (AIT) from
mustard oil, AIT liberated from 5% to 10% (w/w) non-deheated (NDH) hot
mustard flour, and AIT following microencapsulation was examined . . .
Chlorous acid and chlorine dioxide inhibit growth of L.
monocytogenes in caviar.
Sturgeon caviar products are prepared by curing them with salt, but
they generally receive no heat treatment. The salt concentration and
storage temperature are the key factors harnessed to . . .
Inactivate E. coli O157:H7 in undercooked ground beef patties
using trans--cinnamaldehyde.
Undercooked ground beef is a common vehicle for transmitting E.
coli O157:H7 to humans. The USDA recommends that beef patties be cooked
to an internal temperature of 160 F. Since the bacteria can . . .
The survival of foodborne pathogens.(In Brief ...)
The survival of foodborne pathogens in processing facilities is
affected by the composition of surface materials, the availability of
nutrients and moisture, and temperature. Stainless steel does . . .
Alternatives for controlling L. monocytogenes in ready-to-eat
meats.
Controlling L. monocytogenes in ready-to-eat (RTE) meats continues
to be a major concern. Sodium lactate and sodium diacetate are widely
used as antilisterial agents to enhance the safety of RTE . . .
Improve food safety and quality with lauric arginate.
Lauric arginate (LAE), a cationic GRAS-approved surfactant with
broad-spectrum antimicrobial activity, is being investigated as new tool
for improving food safety and quality.
Researchers at the . . .
Bacteriophages may function as novel antimicrobials.
It appears that some foodborne bacteria may be overstaying their
welcome in products after viruses called bacteriophages take up
residence inside them and replicate. The progeny of these . . .
E. coli also present in swine.
E. coli O157:H7, an organism that causes gastrointestinal disease
in humans, is generally associated with cattle. But it can also be
recovered from swine to a lesser extent. Recent research at Iowa . . .
Heat treatments enhance safety of E. coli O157:H7-inoculated mung
bean seeds.
S. typhimurium and E. coli O157:H7 have been associated with
contaminated seed sprouts. Many outbreaks have been traced to seeds
contaminated with low levels of pathogens. For example, strains of . . .
Phytosterols may have antimicrobial activity in pasteurized fluid
milk.
Phytosterols have been known to reduce total serum and low-density
lipoprotein cholesterol concentrations by lowering the extent of
cholesterol absorption in the intestine. Several studies have . . .
