The necessary material for making chocolate cake is pure cocoa powder, and no other materials are added. Generally, supermarkets sell beverage granules with sugar and milk powder, which is not suitable for use. When making chocolate cakes, 30 grams of cocoa powder is usually added to an average cake weighing two pounds. Because cocoa powder is acidic, a large amount of it will make the cake sour, so a small amount of baking soda can be used as a neutralizer to neutralize its acidity and deepen the color of chocolate cake.

But powder is the charm of chocolate. Researchers have found that cocoa powder rich in chocolate can reduce the effect of high cholesterol on arteries. They studied low-fat cocoa powder extract, not ordinary high-fat chocolate bars or hot chocolate drinks.

Dr TissaKappagoda of the university of California announced this discovery at the recent biological experiment conference in 2000. In their research, he and his colleagues found that cocoa powder extract contains a bioactive substance, which can protect rabbits' arteries from cholesterol. Dr Kappagoda explained that this cocoa powder extract is the source of antioxidant flavonoids, which can prevent the chemical process of arterial diseases caused by cholesterol. These compounds can be found in vegetables, fruits and tea.

To prove this, they did a series of experiments to test the effect of cocoa powder extract on rabbit aorta. Normal aorta has enough relaxation ability to ensure normal blood flow and blood pressure. The damage of cholesterol to arteries limits this diastolic function, which leads to the increase of blood pressure.

In the experiment, they took two groups of rabbits with high cholesterol diet and low cholesterol diet respectively, and directly contacted their aortic tissues with cocoa powder extract. As a result, aortic dilatation was found in both groups. This reaction is the same as that of similar substances extracted from fruits, vegetables and tea.

Dr Kappagoda emphasized that low-fat cocoa powder extract is very different from high-fat chocolate bars and hot chocolate drinks. He pointed out that in the process of chocolate production, most of these substances are removed, and 40%-45% of the calories in chocolate sold in stores come from fat.

As a cardiologist, Dr. Kappagoda disapproves of eating more chocolate. People generally like to eat low-fat food, especially those who have heart disease. But chocolate lovers need not worry. Some companies have noticed this discovery and started to produce low-fat chocolate, which is acceptable in taste and appearance.

Ingredients: 3 big bananas, 6 teaspoons of orange juice, 1 teaspoon of cocoa powder, 2 teaspoons of starch, 3 teaspoons of milk, 40 grams of dark chocolate, 1 5g of butter,175g of syrup (as follows),100g of common flour,1teaspoon.

Exercise:

1. Peel the banana, slice it, and put it on a plate with orange juice for later use.

2. Mix cocoa powder and starch in a bowl, then stir and pour in milk. Cut the dark chocolate into small pieces, put it in a frying pan with butter and syrup, heat and stir with low fire until it is completely mixed, then add the cocoa powder mixture, boil it with low fire, and stir and stew 1 min. Then remove the pot from the fire and the chocolate sauce will be ready.

3. When making cookies, sift flour and cocoa powder into a bowl, then add eggs and oil, and then slowly add milk until the mixture becomes a uniform paste. Heat a little oil in a frying pan with a thick bottom, pour in a little paste, slowly shake the frying pan to spread the paste evenly, and heat it on medium heat until the bottom turns golden yellow. Turn the pancake over and continue frying the other side. Pour the biscuits out of the pot and keep warm. Repeat the above actions until all the cakes are fried.

4. Reheat the chocolate sauce for 1-2 minutes. Put the banana on the biscuit, fold the biscuit into a triangle, and then pour a little chocolate sand and die. You can eat it.

Supplement: syrup practice

Put the sugar in a boiling pot, then slowly pour in water, cook over medium heat and stir with a spoon until it becomes syrup.
