Do you know the quick freezing technology of fresh corn?

Fresh corn is delicious nutritious, but are you sure the corn you eat is fresh?

Strictly speaking, the best harvest time of fresh waxy corn in milk stage is very short. The freshest corn is within 6-10 hours after picking. After a long time, corn will gradually lose many nutrients trace elements in fresh waxy corn seeds.

The reality is: farmers pick corn, sell it to middlemen, middlemen sell it to retailers, retailers take it to various markets to sell it. It has been a long time, at least 24 hours more. In a few days, although there are still leaves on the corn, it is "fresh" in the actual sense.

Sugar will be converted into starch accumulated in the peel, resulting in the decrease of sweetness, thickening of peel, transformation loss of a large number of nutrients. That's why it doesn't taste good.

Corn is planted harvested at the wrong time. Each corn plant can complete the picking, peeling, cleaning, steaming, quick freezing, freezing other processes within 8 hours of the suitable harvest time, so that fresh nutrition are discounted.

Corn seed selection - planting - harvesting - processing - quick freezing - freezing - Packaging - packing, every link is fine to micro.

Most of the quick-frozen corn manufacturers do seeds, the varieties of corn planted are impure, there are unqualified products such as poor quality flower channeling. However, in order to ensure the production, some manufacturers still harvest, produce sell the inferior ones as good ones, mix the eyes with the fish.

The unqualified corn must be eliminated.

Quick freezing is to freeze the water in the cell rapidly by putting the pretreated corn ear at - 30 ~ - 40 ℃. After freezing, there was little loss of juice in the arrangement, which kept the original color flavor of fresh corn ear.

Quick frozen storage: quick freezing is to freeze the fresh corn at - 25 ℃ refrigerate it at - 18 ℃ after packaging. This method can guarantee the quality of corn for half a year, which is the most effective method to extend the supply period of fresh corn.

The basic technological process is as follows: raw materials → removing bracts removing whiskers → selecting → blanching → cooling → quick freezing → packaging → refrigeration (- 18 ℃).
