Today, let Xiaobian tell you an experiment, soup Why use clean water!
Experimental Method: mung bean as the raw material, the proportion of beans and water is 1:10, stamped cooking for 10 minutes. Firstly, the oxidation resistance of the red and green bean soup was measured; Subsequently, each with tap water, mineral water, pure water, distilled water, boiled bean soup; Finally, the water was adjusted to different pH values ??to cook bean soup.
Experimental results: The results show an antioxidant, red bean soup antioxidant capacity was significantly lower than green bean soup. The more red color, the lower the antioxidant capacity, which means green bean soup hot weather better than the red bean soup. Different
2. Different color quality cooking bean soup. Distilled water color most green, and long-term change. Followed by pure water and mineral water. Water boiled mung bean soup color changing fast, in almost every minute after contact with air are significantly darker, quickly turned red.
3. The pH can greatly affect the color effect soup. Acidic water boiled color change is small, and slightly alkaline water discolored very quickly after cooking.
Experimental recommendations: bean soup boiled pure water is preferably used directly. If not, just add half a teaspoon of white vinegar in the water, half a teaspoon of lemon juice or a squeeze, but be careful not to add too much. The specific method is to boil the water first, then into the green beans, continue to simmer for 8-10 minutes stamped. Broth decanted, boiled bean soup such a long time may be retained in air green color, and the effect of hot weather is good. The remaining beans can continue to cook green bean, mung bean porridge or boiled rice increased.
Also, be careful not to add a base boiled mung bean soup, because the alkali will not only greatly reduce the effects of hot weather bean soup, but also seriously undermine green beans rich in B vitamins . (China Agricultural University, Food and Nutrition Research)
