It's time to eat corn this season. Generally, we eat corn oil, sweet corn and waxy corn. What's the difference between these two kinds of corn except the taste? Which has better sugar content, sweet corn or waxy corn?

The difference between sweet corn and waxy corn

1, sweet corn is sweet and waxy corn is soft and waxy.

You can clearly see that there are great differences between the two kinds of corn in color, but there are also great differences in other places. The first is the taste, which is very different. Sweet corn tastes sweeter and contains more water, so many people like to put sweet corn in soup and fried meat. Waxy corn tastes soft and waxy, with less water and slightly light taste, but it tastes soft and waxy, so the methods of waxy corn are mostly boiling, steaming and frying.

2. Sweet corn is more nutritious than waxy corn.

The nutrition of these two kinds of corn is also very different. Sweet corn has a high sugar content, but protein is higher than waxy corn. There are many nutrients in sweet corn that waxy corn does not have, so sweet corn is much more nutritious than waxy corn, so you can choose to buy corn according to its nutritional value.

3. The storage time of waxy corn is longer than that of sweet corn.

When buying corn, you should not only choose the kind and buy your favorite taste, but also consider the preservation time of corn. The storage time of corn may determine what kind of corn you want to buy and how much corn you want to buy. Waxy corn contains more starch than sweet corn, so the storage time of waxy corn is longer than sweet corn, and sweet corn is easy to deteriorate.

However, it should also be noted that whether it is sweet corn or waxy corn, the preservation time is basically a reference, because if the preservation environment is not good, corn will also go bad. Or the quality of corn itself is not good and it is easy to deteriorate, so don't eat deteriorated corn, otherwise it will affect your health.

Which has higher sugar content, sweet corn or waxy corn?

Waxy corn has high amylopectin content, and the sugar rise rate after meal is faster. Not only corn, but also sticky staple foods such as rice, glutinous rice and sticky sorghum have higher blood sugar after meals. Different from waxy corn, sweet corn has high water content, low amylopectin content and slow blood sugar rise, which is more friendly to people with high blood sugar. Moreover, the GI value (glycemic index) of boiled sweet corn is 55, which belongs to medium GI food, far lower than the white rice we often eat (GI value is 90, which belongs to high glycemic index food). However, if corn is processed into corn flour and corn flakes, the GI value will increase, reaching 68 and 79 respectively, which is not recommended for diabetics.
