Starch is the carbohydrate which is contained in potatoes, rice, wheat, corn and other cereals. You can be necessary to turn starch into sugar if you are going to cook independently beer as sugar is transformed to alcohol in the course of fermentation. For transformation of starch into sugar wheat and corn is most often used.
1. Crush seeds of wheat or corn in the crusher.
2. Pour a ground grain into ware for thermal processing and add to it 2 parts of water.
3. Warm up mix approximately to 65-70 °C. Maintain such temperature of mix about 2 hours. At this time enzymes in grain turn starch into sugar.
4. Pour out a part of a ground grain and set aside.
5. Add an iodine drop to mix.
6. Look whether mix changed the color. If iodine brightened or became yellow, all starch turned into sugar. If it remained dark, it is necessary to keep mix at the above-stated temperature still some time.
