Summary
Scientists at the
University of
Surrey have found that a
derivative from wood or bark can enhance the antimicrobial activity of natural
compounds that are mildly antimicrobial by up to 2000 times. This can be used
for many cost effective, natural, long-lasting, anti-microbial products. For
example in hospitals to tackle the spread of MRSA, for the treatment of work
surfaces, on fresh food to prevent spoilage and for poultry bedding materials to
prevent ammonia emissions.
Benefits
For the food industry
our antimicrobial composite offers:
- Decreased microbial
activity on the produce
- Reduced growth of
food pathogens
- Reduced spoiling to
the food
- Works at elevated
moisture levels as the active ingredient is virtually insoluble in water
- Safe. The materials
are already classified as GRAS (generally regarded as safe)
- Effective at very
low concentrations of active ingredient
- No taste or smell
- Persistent, giving
long term protection
- Better long lasting
quality produce
- Reduced wastage
- Cost effective,
making it attractive to industries with very small profit margins
- Environmental damage
reduced
Applications
Food packaging and
treatment
Within the food
industry, anti-microbial products might be used to wash food or as additives to
processed foods or to preserve perishable raw items; fruit, vegetables etc. Increased food safety regulations and
the cost of recalls due to contamination are driving processors to search for
better solutions to reduce pathogens and spoiling microbes in their
produce. In the wake of changing
lifestyles, consumers are looking for convenience foods that are safe over a
long storage period, heightening the role of shelf-life extenders.
Pre-harvest waste of
fruits and vegetables is around 30% despite the extensive use of pesticides. A
further 30-50% is lost post-harvest.
Because post harvest use of traditional pesticides is prohibited or is
being phased out, the industry has limited options to prevent spoilage.
