Milk with Shelf Life of 9 Weeks
The best and time-tested method to extend milk’s shelf life
is the process of Pasteurization developed by Louis Pasteur in 1864, i.e. the
process of heating milk to kill pathogenic bacteria and other microbial load.
But the main reason milk is so hard to work with – is its mere week-long shelf
life. But now, scientists have used an innovative method to increase the
temperature of milk by 10 degrees Celsius during the pasteurization process –
adding increasing the shelf life to more than 9 weeks.
“It’s an add-on to pasteurization, but it can add shelf life
of up to five, six or seven weeks to cold milk. With the treatment, you’re
taking out almost everything. Whatever does survive is at such a low level that
it takes much longer for it to multiply to a point at which it damages the
quality of the milk.”
The study was funded by the Agricultural Research Service of
the U.S. Department of Agriculture, the Center for Food Safety Engineering at
Purdue University and New York-based Millisecond Technologies Corporation, and headed
by Bruce Applegate, Purdue associate professor in the Department of Food
Science.
“[Pasteurization] has limitations, which include cost
effectiveness, high energy input, and reduction of product quality/organoleptic
characteristics. In an effort to reduce these limitations and extend
shelf-life, this study examined a novel low temperature, short time (LTST) method
in which dispersed milk in the form of droplets was treated with low
heat/pressure variation over a short treatment time, in conjunction with
pasteurization,” reads their study.
Whale Naval Sonar
Banned Unless Waters are Mammal-Free
The Ninth US Circuit Court of Appeals in San Francisco has restricted
the use of the SURTASS/LFA – a long-range system that emits loud & low-frequency
signals in the range of 100Hz to 500Hz (the same range used by marine life as
well), unless the waters are mammal-free. Marine animals sometimes mistake the
signals for predators – causing a disruption in the natural ecosystem.
Here are details of the ruling from the website - "we
have every reason to believe that the Navy has been deliberate and thoughtful
in its plans to follow NMFS guidelines and limit unnecessary harassment and
harm to marine mammals. The result is that a meaningful proportion of the
world's marine mammal habitat is under-protected”
