New food freezing concept improves quality, increases safety and cuts energy use:
"A complete change over to this new method of food freezing worldwide could cut energy use by as much as 6.5 billion kilowatt-hours each year while reducing the carbon emissions that go along with generating that power by 4.6 billion kg, the equivalent of removing roughly one million cars from roads," said ARS research food technologist Cristina Bilbao-Sainz. She is with the Healthy Processed Foods Research Unit, part of ARS's Western Regional Research Center (WRRC) in Albany.
"These savings could be achieved without requiring any significant changes in current frozen food manufacturing equipment and infrastructure, if food manufacturers adopt this concept," Bilbao-Sainz added.
The new freezing method, called isochoric freezing, works by storing foods in a sealed, rigid container -- typically made of hard plastic or metal -- completely filled with a liquid such as water. Unlike conventional freezing in which the food is exposed to the air and freezes solid at temperatures below 32 degrees F, isochoric freezing preserves food without turning it to solid ice.
As long as the food stays immersed in the liquid portion, it is protected from ice crystallization, which is the main threat to food quality.
[...] Another benefit of isochoric freezing is that it also kills microbial contaminants during processing.

I think about their ultimate goal of shoving us all into high density cities where our every step is watched, counted, and controlled.

High density housing along mass transit corridors is nearly every urban planner's wet dream. Their arch-nemesis is what they call 'sprawl.'

I don't want sprawl. I moved to a small town, and into a house that is much older than me, 30 minutes outside the local metropolis on purpose.

I would guess that "they" are people in government. Those are the folks that want to control every aspect of our lives. "They" are not to be trusted under any circumstances as their goals are not good for us but designed to enrich themselves at our expense.
