Changes in Protein, Nonnutritional Factors, and Antioxidant Capacity during Germination of L. campestris Seeds

Abstract EN

The changes in SDS-PAGE proteins patterns, oligosaccharides and phenolic compounds of L.

campestris seeds, were evaluated during nine germination days.

SDS-PAGE pattern showed 12 bands in the original protein seeds, while in the samples after 1–9 germination days, the proteins located in the range of 28–49 and 49–80 kDa indicated an important reduction, and there was an increase in bands about 27 kDa.

On the other hand, oligosaccharides showed more than 50% of decrease in its total concentration after 4 germination days; nevertheless after the fifth day, the oligosaccharides concentration increases and rises more than 30% of the original concentration.

Phenolic compounds increased their concentration since the first germination day reaching until 450% more than the original seed level.

The obtained results are related with liberation or increase of phenolic compounds with antioxidant properties, allowing us to suggest that the germination would be used to produce legume foods for human consumption with better nutraceutical properties.
