Bread that lasts for 60 days could cut food waste (BBC)

By Matt McGrath
Environment correspondent, BBC News

An American company has developed a technique that it says can make bread stay mould-free for 60 days.

The bread is zapped in a sophisticated microwave array which kills the spores that cause the problem.

The company claims it could significantly reduce the amount of wasted bread - in the UK alone, almost a third of loaves purchased.

The technique can also be used with a wide range of foods including fresh turkey and many fruits and vegetables.

World of waste

Food waste is a massive problem in most developed countries. In the US, figures released this year suggest that the average American family throws away 40% of the food they purchase - which adds up to $165bn (£102bn) annually.

4. A lot of that molds before anyone can use it.
Sat Dec 1, 2012, 04:01 PM
Dec 2012

Our local food bank has more bread to hand out than anything else, and a lot of it gets discarded because of mold. Stores usually dump the bread on or a day before the sell-by date, but if there is any delay delivering it to the distribution point, much of it is lost to mold. Since they are only open three days a week, there is up to four days delay guaranteed ...

Any such bread needs to be stored in the refrigator or freezer, or it will start to mold before it can all be used up.

"radiation" is the term used for alpha, beta, gamma and neutron particles.

microwaves are closer to radio signals then gamma radiation.

Yeah, that's knee-jerking.

All anyone wants to know about sixty-day bread expiration periods is what the health consequences might be.

Saying it will reduce food waste is like claiming that integrating soda can tops into the can was a significant blow against aluminum waste.

There's a way to reduce close to 100% of food waste already, and it's called composting.

Sat Dec 1, 2012, 04:10 PM
Dec 2012

resistant to mold. I have seen this repeated with more than one or two loaves and a duration of up to maybe a month in which a given loaf developed no mold. I didn't test it systematically, but I definitely noticed that hemp bread is much more durable than any other kind of bread and I think it might be because hemp has natural anti-biotic properties, or at least that's what I have heard about it.

11. You mean anti-fungal properties?
Sat Dec 1, 2012, 04:17 PM
Dec 2012

Since while hemp does have anti-bacterial properties it would have nothing to do with mold - which is a fungus not a bacteria.

My theory on your hemp bread is this...generally the hemp or flax bread I've bought were much drier (ie less spongy/moist) than plain wheat bread. As such, they don't mold as readily because the moisture content is lower. Also, hemp DOES have anti-fungal properties - it's why when I used hemp cloth diapers on my babies, the hemp didn't get mildew smell but the cotton (And fleece covers) did. So perhaps that does play a role.

At any rate, I'd be highly unlikely to buy this bread. Sounds like twinkie bread to me.

Im not sure how eliminating endospores is going to keep bread from getting moldy. You can pressure cook grains & flour for 2 hours, and the minute it hits open air, it will likely get trich growing on it (I've seen this in mushroom cultivation). In fact, sterilized grains can be more prone to contamination due to lack of present competing microbes that leave the substrate wide open for colonization.

This is probably only useful to sealed, unopened bread in air-tight (or filtered) bags.

She'd buy it when it was on sale and put it in the freezer and we'd stick it in the toaster quickly to warm it up. We got good at knowing how long it would take.

Or just selling various size loafs - larger, and half-sized.

Sat Dec 1, 2012, 07:04 PM

Lots of it. If you haven't noticed, it starts to char. And, as for how good for you that is:

Q: Can eating burnt toast give you cancer?
A: Maybe. Some chemicals in burnt toast have been linked to cancer.
...
The most well-known chemical in burnt toast is acrylamide, which is produced when sugars and certain amino acids – the building blocks of proteins – are heated together during the cooking process.

This potentially harmful chemical is mainly found in starchy foods such as potatoes (and other potato products), along with baked goods, including bread and, of course, toast.

The level of acrylamide in these foods increases with higher cooking temperatures and longer cooking times. "You would expect there to be reasonably high levels of acrylamide in burnt toast," says Brent.

While toast contains less acrylamide than potato chips and fries, work by FSANZ in 2004 found that toasted white bread is one of the main food sources of acrylamide in the Australian population. This is because we eat more white bread than brown, but white bread might also have slightly more acrylamide in it than other types of bread.

That's what I do. I live alone. I don't eat a lot of bread--just a few slices a week. I just pull a few slices out when I need them. If I want to use the bread right away, it only takes about 15 seconds to thaw it in the microwave. If I am making toast, I just put the bread straight in the toaster oven without thawing it. It toasts just fine. And, I have never noticed any change in quality by freezing the bread.

One of my gripes with store-bought sliced bread is that the loaves are usually so damn big. I know of only one brand that sells a "1/2 loaf". And, all those nice whole-grain breads out are wide-pan, so that each slice is really a slice and a half. They have close to 200 calories/slice, which really stinks for those of us trying to watch our weight. I wish they'd make them in smaller, more reasonably-sized loafs. Perhaps less bread would be wasted if they didn't force such large portions on us.

The freezing part, not the small loaves part (although I can see how that would be helpful too, it's just I have 4 kids and 1/2 loaf is pointless for me
I freeze all my bread. I usually leave one loaf out on the counter for the kids and when it's gone, I pull another one out of the freezer. If a loaf of bread or another storebought baked good is nearing its expiration date, I split it up into plastic bags and stick it in the freezer. I did this recently with some muffins - put in them in sandwich bags in the freezer and pulled them out for the kids' lunches everyday. It helped to keep the lunch bag cool and thawed by lunchtime.

This is a problem I deal with constantly. I have a refridgerator freezer an it's just not big enough for storing bread. And the smaller loaves that are available are specialty breads and cost anywhere from $1 to $2 more per loaf.

A regular loaf of my store brand wheat is under $1. But we usually end up throwing 1/3 of that loaf out because we just can't eat it all fast enough. I would much rather buy a half-loaf. At least that way, too, we would cut down on our bread intake from not feeling like we've got to eat as much as possible in order to waste less of it.

I've tried throwing it out for the birds but they don't seem particularly interested.

Sat Dec 1, 2012, 05:06 PM

Today's bread has to be delivered to stores the day it's made to give grocers a fair chance to sell it...so, there have to be a LOT of local bakeries.

Now consider...you can haul from Kansas City to anywhere in the US in 35 hours or less. Run team drivers and it's a day and a half. So...let us assume whoever buys Hostess wants to cut down on labor. If they want to practically eliminate it, building a huge long-shelf-life bread bakery in either Walcott, Iowa, or Oak Grove, Mo., and baking all the bread for North America there would do it.(Both towns have huge truck stops where you can easily hire truckers to haul bread - eliminating the expense of keeping your own truck fleet.)

It would also turn bread into a distribution center item, and this is a scary thought: if you knew you could sell 700 million loaves a week, why not build a 200 million loaf/day operation and make the bakers part timers without benefits?

The upside is the ability to respond to disasters. If a hurricane hits an area, there won't be bread for a while. With this bread you could stage loads of bread right outside the expected damage path, then haul it in as soon as the wind stops blowing.

It would certainly change the dynamics of the industry. It would also probably bring prices down. This is especially important for people with limited means. White bread is pretty cheap already and it's use probably should not be encouraged, but a lot of shelf space is taken up by various kinds of whole-grain breads too.

There would also be an impact on agriculture. Some sources estimate that a third of bread is wasted in the US -- that's a lot less arable land that has to be used for wheat.
