2. Cook sweet corn for 8 minutes and sticky corn for 10 minutes. The ripening time of sweet corn and sticky corn is different. If you cook in the same pot, after cooking for 8 minutes, pinch out the sweet corn first, and then continue to cook the corn for 2 minutes.

3. Sweet corn is a vegetable and sticky corn is a grain. According to taste, there are sweet corn, sticky corn and old corn. The taste of corn is mainly determined by its starch content, while the amylopectin content in sticky corn is relatively high, so the taste is sticky and waxy. Need to be reminded that sticky corn can increase sugar faster, and diabetics should eat less. Hard old corn has high amylose and crude fiber content, which is the first choice for dieters. Generally speaking, sticky corn and old corn have high starch content, which belong to grain and can be used to replace staple food. Sweet corn contains a lot of water, vitamin C and soluble sugar, but its starch content is relatively low, so it is regarded as a vegetable containing starch.
