Do they measure canned food protein before or after it's canned?

I mean when you can something it loses some of it's nutrition. Does the label show before it's canned or do they weight and measure after it's canned for a while? I have canned organic mushrooms and was wondering how accurate the label is.

Thanks,

Go by the label on the container. Assume that the company took that into account.

It's most likely the firm canning the mushrooms used information from the USDA database rather than conducting their own analysis. Here's a link to the USDA entry for canned mushrooms: https://ndb.nal.usda.gov/ndb/foods/show/3012?manu=&fgcd=&ds=Standard Reference

It really depends when you are doing the comparison. Fresh picked produce used immediately after harvest has more nutrients. Fresh produce that is a week old can lose up 50% of its nutrients. Canning will cause nutrient loose but, the canning process itself will stabilize the product.

"THE FACTS

One way to make healthful meals more economical is to incorporate canned fruits and vegetables, which are often cheaper and more convenient than fresh produce. But does that mean sacrificing nutrients?

Thankfully, it does not. Studies show that like frozen produce, canned produce – provided it is free of added salt and sugars – has a nutrient value that is often as good as, if not better than, that of fresh produce.

Freshly picked fruits and vegetables typically do start with more vitamins and nutrients. But degradation occurs during shipping, and produce sold in many markets often sits on shelves or in storage for days before it reaches a shopper’s basket.

Canned produce can lose some of its nutritional value as well, particularly water-soluble nutrients like vitamins B and C. But over all, the nutrients in canned fruits and vegetables tend to be relatively stable because they are protected from the deteriorating effects of oxygen, a fact emphasized in an extensive report on the subject published in The Journal of the Science of Food and Agriculture by researchers at the University of California, Davis.

“Fresh fruits and vegetables usually lose nutrients more rapidly than canned or frozen products,” the researchers wrote. “Losses of nutrients during fresh storage may be more substantial than consumers realize” and may not be reflected on nutrition labels.

At the end of the day, of course, either option is a healthy one.

THE BOTTOM LINE

Despite their reputation, canned fruits and vegetables retain many of their nutrients, in some cases better than fresh produce does."
