Cake-like banana-nut muffins with no saturated fat
« on: August 09, 2008, 12:04:35 AM »
Better living through chemistry.



These are cake-like muffins, quite moist, and will not dry out as fast as more traditional muffins. They are very tender and delicate.

I guess this is more interesting for what it DOESN'T have in it, as much as for what it does. No saturated fat! No trans-fat! No cholesterol (though dietary cholesterol is not the only source thereof in the bloodstream--in fact you could eat no cholesterol and have a high cholesterol level).

Usually to make a cake-like batter, you "cream" a saturated fat and sugar. Oil normally won't work; it has to be saturated, and typically saturated fats are hydrogenated oils, which creates trans-fats which are even worse, because our lipo-protein receptors (which I, personally, apparently don't have enough of!!) were not designed to deal with trans-fats.

I am guessing that the reason this recipe works, is that there is probably some natural soy lecithin in the soymilk out of which the soy yoghurt is made. Lecithin is an emulsifier, which breaks the surface tension between the oil and the water in the batter, and keeps them mixed just like in a "creamed" saturated fat version. The batter looks just like old-fashioned cake batter

Now, I made up this recipe by adapting a recipe for carrot-cake muffins, and reducing the sugar. It then made only 11 muffins, so I had to increase proportions slightly. I think this is correct but it might need to be tweaked a little more.

I would like to try all sorts of variations, but haven't had time to work them out. Zucchini muffins didn't quite work, because the Zucchinis have too much water in them. I will try less Zucchini and more flour to compensate.

RECIPE:

Preheat oven to 350F.
Prepare muffin tins. I lined mine with silicone liners and sprayed the bottoms with non-stick spray. Make sure you can get them out as they will be exceedingly tender and slightly sticky from the carmelized banana-sugar.

Beat this together:

?1/2 cup soy yoghurt
1/4 cup sugar (I use turbinado for the flavor)
1/3 cup oil (I used mixture of canola and flax seed)
1/2 tsp vanilla extract
1/2 tsp butter flavoring
1/4 tsp sea salt

Sift in mixed dried ingredients, in 2 or 3 batches, and beat until smooth:

3/4 cup flour. I used unbleached pastry flour, but all-purpose should work. I would guess that whole-wheat pastry flour would work too, since we're not trying to form any gluten anyway.
3/4 tsp baking soda
1/2 tsp baking powder
1/4 tsp cinnamon
1/8 tsp nutmeg
?optional: 3/4 tsp soy protein powder (to boost the protein of the flour a little--serves no culinary purpose). This is a fairly inexpensive ingredient I buy from trader joes that is vitamin-enriched

You don't have to beat vigorously, and it mixes pretty fast, actually.

Mix in this:

1 very ripe banana, mashed
1/4 cup chopped walnuts or, better, pecans

Fill each cup 2/3 full of batter. Don't overfill as this batter is fairly delicate, lacking any eggs or much leavening.

Bake approximately 26 minutes or until toothpick comes out clean.

Now this is important: let the muffins cool before handling them, or they will COLLAPSE. I use silicone muffin/cupcake liners, sprayed with non-stick spray, and pull those out of the muffin tin but leave the muffins in the liners until fairly cool.

I use a lot of soy powder. The reason is because it keeps well (it is defatted), and it is high in lysine so that it balances the unbalanced protein in wheat. I typically use about a teaspoon per cup of wheat flour. I just checked the label and it is indeed vitamin-fortified. Just a little so it's not like we'll OD on anything. Note I said POWDER not FLOUR--this is soy protein isolate; it doesn't go rancid, and it doesn't contain significant amounts of phytoestrogens, the hysteria over which has been completely overblown (other commonly eaten legumes contain even more phytoestrogens, which seem to be mostly broken down anyway, plus they have roughly 1/1000th the activity of real estrogen).

The flax-seed oil and the nuts are rich in essential fatty acids, which are useful to humans for building hormones. Good for growing children...including babies! The vitamins in the soy powder are a good way to sneak vitamins into my wife, who otherwise "forgets" to take hers.

I will keep working on this one, because it is pretty good (it was a huge hit with my family), and I could probably tweak it more with some whole wheat pastry flour.

A word of warning about the canola and flax oils. These oils are healthy when injested at room temperature. At that temperature, they maintain their chemical structure and they indeed do not have any saturated fats. The problem is that when they are heated to cooking temperatures, they change to form lipid-peroxides which are actually more damaging to human health than if you had simply used the regular old saturated fat/cooking oil in the first place. The best alternative that I have found is coconut oil. Granted, it's not healthy, but it's the least unhealthy option of all.

Highly polyunsaturated oils are indeed unstable, and the free radicals they produce as they go rancid are destructive.

Canola oil is fairly safe for a long time, because it is mostly monounsaturated.  That's why you can store it on a shelf without refrigeration (much like olive oil), for quite a while.

It does have a small amount of polyunsaturated oil, and monounsaturated oils go rancid eventually anyway.

Flax seed on the other hand is so highly polyunsaturated, that it really needs to be stored in a sealed, light-blocking container in the refrigerator, and preferably used within a few months of opening.

As for cooking, it is quite safe to bake with it. The reason is that the time isn't long enough and the temperature not high enough to damage a significant amount of the Omega 3s or Omega 6s (which, by the way, are in the wrong ratio in flaxseed oil!). Most of the baking time, the batter is below boiling point.

It used to be the primary oil used by long-lived Swedes--probably still quite common in Scandinavia.

If it were unsafe to cook with, coldwater fish would have the same problem, due to the high levels of omega 3s and omega 6s. I have, however, seen warnings against cooking with flax-seed oil--sponsored by fish oil producers!

Several sources recommend not frying with it above 325F, at which point it starts breaking down. But it would never occur to me to fry with it, considering its expense in this country, and the fact that it is so highly polyunsaturated.

Safflower oil, which is high in omega 6s, has the same problem, and should not be used for frying.

The current wonder-oil for frying is rice bran oil. Although it is liquid, it is so low in polyunsaturates that it has the amazingly high smoke temperature of 497F.

Baking, not frying...that's the key I was missing. I'm going to look into rice bran oil.
