Embodiment 1
[0043] The preparation method of the quick-frozen sweet corn grain of the present embodiment comprises the steps:
[0044] (1) Harvesting of raw materials: The best harvesting period of sweet corn is the milk ripening period, that is, 18 to 30 days after pollination. Generally, the pollination time is calculated when the ear of sweet corn spits out filaments about 1 inch (3.3 cm). When harvesting, the water content of sweet corn kernels should be 70% to 73%. At this time, the taste and flavor of sweet corn are the best. Harvested sweet corn should not stay in the field for a long time and be exposed to the sun. Do not squeeze it too much during transportation and handling to avoid damage to the sweet corn kernels;
[0045] (2) Acceptance of raw materials: when harvested, the wrapping leaves of sweet corn should be green. The grains are plump, yellow or light yellow in color, uniform in color, free of variegated grains, uniform in size and arrangement, bald, missing grains, an...
Embodiment 2
[0066] The preparation method of the quick-frozen sweet corn grain of the present embodiment comprises the steps:
[0067] (1) Harvesting of raw materials: The harvesting time is 18 days after pollination. The harvested sweet corn cannot stay in the field for a long time and be exposed to the sun. Do not squeeze it too much during transportation and handling to avoid damage to the sweet corn kernels;
[0068] (2) Acceptance of raw materials: when harvested, the wrapping leaves of sweet corn should be green. The grains are plump, yellow or light yellow in color, uniform in color, free of variegated grains, uniform in size and arrangement, bald, missing grains, and moth-eaten are not serious;
[0069] (3) Peeling and defilament removal: After the sweet corn enters the factory, it should be placed in a cool place and immediately peeled and processed. The time from sweet corn harvesting to processing cannot exceed 6 hours. If the processing cannot be completed within 6 hours, it ...
Embodiment 3
[0084] The preparation method of the quick-frozen sweet corn grain of the present embodiment comprises the steps:
[0085] (1) Harvesting of raw materials: The harvesting time is 25 days after pollination. The harvested sweet corn should not stay in the field for a long time and be exposed to the sun. Do not squeeze it too much during transportation and handling to avoid damage to the corn kernels;
[0086](2) Acceptance of raw materials: when harvested, the wrapping leaves of sweet corn should be green. The grains are plump, yellow or light yellow in color, uniform in color, free of variegated grains, uniform in size and arrangement, bald, missing grains, and moth-eaten are not serious;
[0087] (3) Peeling and defilament removal: After the sweet corn enters the factory, it should be placed in a cool place and immediately peeled and processed. The time from sweet corn harvesting to processing cannot exceed 6 hours. If the processing cannot be completed within 6 hours, it mus...
