Northeast quick-frozen corn is a special sticky corn variety in Qiqihar city of Heilongjiang Province. There are several main varieties of quick-frozen corn, such as quick-frozen flower corn, yellow corn black corn. It is harvested in kenqing season, processed into northeast quick-frozen sweet sticky corn by advanced production technology such as peeling, cleaning, mold removing, cooking, quick freezing, packaging, etc Quality.

Blanch the corn then freeze it. Blanching is a key process in corn processing, the blanching temperature time must be strictly controlled. The effects of blanching are as follows:

1. It can inactivate the enzymes in the arrangement of corn, because the low temperature cold storage will make the enzyme lose the activity, the slow physiological chemical reactions are still carried out, so that the nutritional components of the grain are destroyed.

2. Blanching can also kill some microorganisms eggs to ensure the hygiene food safety of the products.

3. The air in the blanched corn kernels is squeezed out, which reduces the swelling pressure of ice crystal formation during freezing, increases the resistance to swelling pressure, correspondingly reduces the oxidation degree of the material, so as to maintain the color nutrition of the product.

Blanching can use boiling water steam, the temperature is 93 ~ 100 ℃, according to the water temperature control blanching time, generally 3 ~ 8 minutes. If the blanching time is too long, the nutrients will be lost seriously, the quality indexes such as color taste of the products will be greatly reduced.

Corn kernels should be blanched immediately after threshing. Blanching can be carried out in a sandwich pot a continuous blanching machine. Blanching method is to boil water first, then add sweet corn kernels, water corn grain share is 4:1.
