Quick frozen corn is soft and delicious after being cooked. However, the corn family has many members, including glutinous corn, sweet corn, colored corn, and variegated corn. Faced with different types of frozen corn, many people either don't know how to distinguish their choices or have doubts about the safety of the new face corn. What are the correct ways to "open" a bag of frozen corn? Let's take a look at what experts in the field of food and nutrition science have to say. Selection: Different colors and nutrients. Although corn is a coarse grain, it is rich in nutrients. Research shows that corn is rich in various nutrients such as protein, fat, dietary fiber, vitamins, unsaturated fatty acids, and minerals. In addition, it also contains a high amount of magnesium and glutathione, especially linoleic acid, which is as high as 60%. Corn is a crop with rich colors. In addition to traditional yellow and white, there have also been mixed colors of black corn and white yellow purple corn on the market in recent years. Gu Chuanling, a director of the Capital Health and Nutrition Food Society and a registered nutritionist in China, explained that the reason for color differentiation is because the skin and aleurone layer of corn kernels are colorless, and only the endosperm displays color. The difference in endosperm color leads to the difference in corn color. It should be noted that both black corn and colored corn are the result of genetic changes in corn itself, and are not artificially genetically modified products. Generally speaking, yellow corn is rich in β- Carotenoids, lutein, and zeaxanthin are all beneficial to eye health. For office workers who use their eyes more, they can choose yellow corn; Black or purple corn is rich in antioxidant anthocyanins, making it more suitable for people with low blood sugar who need to consume anthocyanins. Quick frozen corn refers to a type of food that treats fresh corn fruits into a frozen state under high-speed freezing conditions. It retains the original taste of corn and only needs to be taken out and cooked in a pot. It can be used as a staple food or as a soup for cooking, making it very suitable for busy office workers. How to choose high-quality frozen corn? During an interview with China Consumer Daily, Gu Chuanling reminded consumers to pay attention to the following three points when purchasing frozen corn: check whether the packaging is intact, whether it meets food hygiene standards, and whether the labeling is complete. Although frozen corn can be stored for a long time, it is still recommended to choose fresh products from reputable brands and with closer production dates. At the same time, it is important to check the packaging for integrity, damage, and deformation. Look at the appearance, mainly to see if the appearance of frozen corn is normal, such as whether there are cracks, discoloration, or softening on the surface. Smell: Although most frozen corn cannot smell the fragrant aroma of fresh corn, there should also be no odor. Eating: Don't lose the core while gnawing on corn. What are the ways to open a delicious frozen corn? Gu Chuanling reminds consumers that they can learn how to "nibble" on corn from several knowledge points, which is healthier and safer. Can eating corn be unlimited? Although corn is a healthy coarse grain, eating more is not necessarily better. According to the recommended amount in the Dietary Guidelines for Chinese Residents (2016), adults are recommended to eat one medium sized corn every day, and the intake of staple foods (medium sized Mantou or half a bowl of rice) should be reduced accordingly to avoid the occurrence of high blood sugar, indigestion, flatulence, etc. Is eating corn okay
