Assessment of quality of popcorn depending on processing of

new polymers

When processing the seeds and sowings by polymers and copolymers, the popcorn quality increases and the flavoring qualities remain the same

The feature of the new polymers is their ability to increase the accumulation of proteins in corn grain by 5-8%

Yield of the smallest modifications of popcorn called "caramel" reduces by 10-20% comparing to the control group.5
