Thick kind skin is formed on corn, the nutriment in corn during boiling is difficult to dissolution.Corn product with other
After cereal is steaming mixed, the corn chewed is suitable with the soft or hard degree of other cereal, and without obvious harsh feeling, excellent taste, its
It is 45~48 points in mouth feel score, is optimal with embodiment 3 (48 points).And comparative example 1 is then 35 points, this is primarily due to right
Content of starch is low in corn in ratio 1, skin slag rate is high causes.And comparative example 2 is then 32 points, this is primarily due to comparative example 2
In corn contain kind of skin and there is coating of wax matter layer on surface, heat resistance is strong, needs the longer time could during boiling
Boil soft.
Overall scoring summation (91~97 points) of embodiment 1~4 is made a general survey of, also much larger than comparative example 1~2 (63 and 66 points),
As can be seen here, the corn product that the embodiment of the present invention 1~4 is provided, without carrying out the procedure of processing such as broken of peeling, both simplifies and adds
Work flow, is avoided that the loss of nutrient again, and include that whole corn kernel has in the corn product obtained by making is complete
Portion's nutrient；Meanwhile, the cooking property of this corn product can be carried out similar to cereal group food with other cereal group foods
Steaming mixed edible, skin slag rate is low, mouthfeel is good, and has strong corn flavor.
Although illustrate and describing the present invention with specific embodiment, but will be appreciated that without departing substantially from of the invention
Many other changes and modification can be made in the case of spirit and scope.It is, therefore, intended that in the following claims
Including belonging to all such changes and modifications in the scope of the invention.
