Protein Hydrolysates Supplement in the Nutrient Solution of Soilless Grown Fresh Peppermint and Spearmint as a Tool for Improving Product Quality

The present study investigated the potential of fresh peppermint (Mentha × piperita L.) and spearmint (Menthaspicata production on a floating raft system combined with commercial protein hydrolysate supplement (Amino16®) in nutrient solution aiming to improve plant product quality. Three levels (0, 0.25 0.50%) were added solution, plants harvested after twenty-four days. Plant growth characteristics recorded, nutritional, essential oil polyphenolic composition determined tissue. addition hydrolysates did not affect or dry weight but reduced height. Nitrate content significantly decreased, while total chlorophyll increased both species. Moreover, further antioxidant capacity, soluble phenol carotenoid contents plants, it In conclusion, may be quality grown system, without adverse effects crop yield profile.
