Baking – What’s causing the metallic aftertaste in the Nutraloaf

bakingflavorfood-science

Thanks to all of the wonderful help thus far, I've finally been able to make my Überfood. It's called "Nutraloaf", and is kind of like a meatloaf with a bunch of other stuff in it.

It has no real taste (not a problem) and the texture is a little mushy (I will try baking it longer in the oven), but the idea is I can simply eat this 3 times a day, every day, and not have to worry about making any other food.

However, one problem is that I'm getting a metallic aftertaste. I don't know if it's the ingredients, or the fact that I used a normal oven instead of a convection/steam oven.

This is the recipe I used.

2 oz Ground Beef
Brown off in kettle and drain thoroughly

4 oz Canned, Chopped Spinach
4 oz Canned Carrots, Diced
4 oz Vegetarian Beans
Open and drain all vegetables well

4 oz Applesauce
1 oz Tomato Paste
1/2 cup Potato Flakes
1 cup Bread Crumbs
2 oz Dry Milk Powder
1 tsp Garlic Powder or Flakes

Combine beef and vegetables. Gradually blend in remaining 
ingredients until well combined. Mixture should be stiff 
but moist enough to spread. Each loaf should weigh 1 1/2 
pounds precooked weight and be scaled to insure proper 
weight. Place mixture into a loaf pan that has been
sprayed with pan release and lined with filter paper.

Each loaf should bake at 300 degrees Fahrenheit in 
convection/steam oven for approximately 40 minutes or 
until the loaf reaches 155 degrees internal temperature.

It is a subtle aftertaste and it went away after I had a stick of Wrigley's gum. I would prefer to not have to chew Wrigley's after every meal, since I don't really like chewing gum. I'm sure a peppermint or buttermint would also help with the aftertaste, but would prefer to fix my nutraloaf recipe or cooking technique.

So how can I remove this metallic aftertaste? Or, where can I even begin looking for what's causing it?

You said that you drained your canned vegetables, but did you rinse them? Sometimes just dumping out the packing liquid isn't enough. I always rinse any beans that I get out of a can at least a few times.
If you wanted to add a little taste you might want to throw in some chopped cilantro. It packs a lot of flavor and overpowers a lot of tastes. Of course some people think it tastes like dirt. I like the idea of an Uberfood. That only puts us a few short steps away from getting all of our nutrition in pill form!
