In canned corn, many useful substances are preserved. They are rich in mineral complexes: potassium, calcium, magnesium, iron, phosphorus. The composition of zein includes the essential amino acids lysine (immunomodulator with anti-diabetic effects) and tryptophan, which is required for the body to produce vitamin B3. Corn vitamins themselves are represented by groups B1, B2, B5 involved in tissue respiration and energy production, carotene and vitamin PP [2].
