Though locally "canned" food refers to food in a metal can, I understand that in the USA the term "canning" is also used for preserving food in glass jars. I suspect you're talking about metal cans anyway. If the can is made of metal, the metal can start to corrode (ie react with oxygen) soon after the can is opened, especially since salt in the food can ...

I freeze bananas in a plastic container, which I wash and reuse. I also wash and reuse Ziploc-type plastic bags, which work equally well, but don't last quite as long. If your wife prefers aluminium, you can probably find an aluminium container (e.g. in an outdoor store), which should last you for several decades.

A few things to keep in mind. Food safety for unrefridgerated food is a very complex thing and the answer very much is "it depends." Factors include temperature, time in the so-called danger zone (40-140F), pH, other bacterial activity, salt content, and much, much more. In general a few guidelines: If your food stays between 32F and 40F you can treat it ...

As for saving energy in the fridge, vegetable storing does not make a difference.* If you want to prolong the life of your produce to reduce waste, it depends on the vegetable. Many veggies and greens generally need to 'breathe', so non-sealed bags/containers or just in the 'crisper drawer' is good. You can buy specialty bags such as perforated ziplocs or ...

I simply freeze them, they don't need a container if you're going to eat them soonish (within a month, perhaps). When you take one out if you run it under water for a few seconds the skin loosens up and they just pop out. I squeeze them into my smoothies. If your wife eats them as a whole fruit, rather than in a smoothie, you can improve the condition ...

Like other fruits and vegetables I would just put them into a plastic container. It is practical to separate the pieces by plastic foil so that they can be easily separated in the frozen state. Both the boxes and foils can be reused without washing for a limited time when kept in cold. Later they can be washed and reused again.

We just freeze bananas in their skins. But I do that when they're getting a bit old, and when I thaw them it's for cooking, so I'm not sure how edible they are.

When you use a refrigerator, very nearly all the energy used by your refrigerator ends up as heat in your home. During winter, that means that the real cost of using your refrigerator is the difference between heating through electricity and heating through your normal heating system for that amount of energy. If you store food outside, you'll lose a lot ...

I would chop them into suitable chunks and pop into a freezer bag, making sure the bags are not over filled and freeze only a few bags at a time on a clear bit of freezer shelf. Once frozen then can be stacked as normal in your freezer. Now I can grab the quantity I need.

I know of one independent place that happily refills the containers they use, if you bring them back clean. In this case the container is used as a portion measure so it wouldn't work with arbitrary dishes. In this case they were the typical plastic takeaway boxes (amazon link). A couple of my colleagues did this; I didn't as I could dishwash and reuse ...

Some models have a holiday mode which can be used with care. On a fridge-freezer it often stops cooling the fridge compartment (AEG) or at least stops cooling it enough to keep food fresh. Check the manual for your model if you plan to leave anything in your fridge (except things that don't really need to be chilled like chocolate in a hot climate, sealed ...

Bacteria grow well at temperatures between 4 C and 60 C, generally, the warmer the better for the bacteria. Generally refrigerators are set to operate at temperatures around 4 C. Freezers operate at temperatures below zero degrees Celsius. Most bacteria do not thrive in such cold temperatures. Mould/Mold also like warm temperatures and as with bacteria, the ...

Both of the links you shared are important videos to watch for anyone interested in learning about the process and should be considered required viewing material in classrooms where agriculture is taught. The process works well and can be applied to other kinds of livestock as well. The "chicken tractor" is a popular method that employs similar techniques ...

A lovely question! I can remember when there were no plastic bottles. Glass - made from one of our most common minerals - quartz, is not likely to run out, and is fully recyclable. I still get my milk in glass bottles which are collected by the milkman washed out and used again, with almost zero energy use; not even in transport as they are collected during ...

When comparing similar products and packaging, a quick and practical rule is that the product with the highest content weight / packaging weight ratio has the lowest impact. But in practice it's much more complicated of course. Things to consider are: The product itself usually has a larger environmental impact than its packaging, so not wasting any cream ...

Sugarcane and natural fiber are your best bets, but even they won't hold up to hot wet food over time. You could consider corn-based plastic, but these are biodegradable rather than compostable; still that's better than styrofoam. You may also be able to find better prices on your heavy duty lined sugarcane or natural fiber containers if you buy very large ...

Some common brands in the UK used glass within the last couple of decades; a few still do, but call themselves "cordial". I recall plastic caps on some, and metal caps on other brands. In France the equivalent (more of a syrup) is often sold in metal bottles - like 1 litre cans with plastic lids. I'm not sure whether they're steel or aluminium, and don't ...

Although it seems logical that a refrigerator would be more efficient since it doesn't have to keep things as cold, there are a few different factors affecting real-world performance. Freezers are simpler to operate. In a freezer there's only a top end on the temperature range. From refrigerator manufacturer LG you can see the range in the refrigerator is ...

It appears that some of these thermostats have "compressor delay protection," such as this one: https://www.amazon.com/dp/B01HXM5UAC/?th=1

I think the greatest efficiency improvement can be obtained by cleaning the condenser coils on the bottom and/back . In a home unit the coils,especially on the bottom collect a lot of lint , pet hair , etc. Vacuum them annually or more often. I have also added aluminum window screen to protect the coils from lint. If you use foam ,I think you will find ...

Cattle have become unpopular because they have been accused of farting methane. This is the main answer to your question. However in ecologically sound pastures cattle do restore CO2 to the soil, and they probably fart much less. If their "emissions" have been measured on cattle fed on a single species of newly sown grass, or on silage, they would not be the ...

if you are really interested in these types of issues specific to your own footprint (rather than in general for an average person with recycling services), you may want to just call up your local recycling facility. They may be able to tell you how these products are recycled, or they might offer tours so you can see it yourself. There are many ...

As sustainability is concerned, you might want to go all plastic free. Here is one of the many resources you can easily find online, may it be about avoiding plastic or best storing ways (there is a loooot to be said about): http://www.thekitchn.com/how-to-store-fruits-and-vegeta-152591

In order to sustain the vegetables as much as possible, I use vegetable bags and put them in the vegetable drawer of the refrigerator. The veggies need to breathe. They last longer that way.

The normal no refrigeration ways work just as good in winter too. Can, salt, and dehydrate. I still dry garden veggies and can with a water bath just like grandma taught me 20 years ago.
