Starch content of maize

Zea mays L.

Starch content is a key indicator of maize grain quality, determining its energy value for feed purposes and product yield during industrial processing.

In the reference 518 varieties crop Maize, where this is mentioned in the description.

The starch content in high-quality maize grain usually ranges from 60–72%. Values above 70–71% are considered high and depend on the genetic characteristics of the hybrid, growing conditions, and harvest timing, while values below 60% often indicate incomplete grain filling and maturation.

For laboratory determination of starch content, the polarimetric method is used, where a specific conversion factor of 1.879 is applied for calculations, accounting for the optical activity of the components specific to maize grain. This parameter is crucial for animal husbandry, where the type of starch is important for its fermentation rate, and for the processing industry, which evaluates starch yield and the structure of its granules.
