| More Details: | The major production of artisanal and industrial wines is elaborate in the Ica Valley, Peru. The objective was to evaluate the antioxidant activity of polyphenols and permissible values of glyphosate in artisanal wines from the Pisco Routes of the Ica Valley, Peru. Samples: six coded artisanal wines and two commercial brands as references (60088 and 60089). Total polyphenol content (TPC) was found between 107.90 ± 0.30 (60091) and 234.73 ± 0.61 mg GAE/100 mL (60084); total flavonoid content (TFC) was between 9.70 ± 0.30 (60091) and 16.83 ± 0.25 mg QE/100 mL (60084). Antioxidant activity: DPPH between 34.9 ± 0.44 (60091) and 55.6 ± 0.30 mM TEAC/100 mL (60085). FRAP between 42.50 ± 0.36 (60091) and 117.3 ± 0.44 (60085). Correlation relationship: TPC/DPPH (mM TEAC/100 mL) for 60086 (r = 0.7302, R2 = 0.5332), 60091 (r = 0.8029, R2 = 0.6447), 60085 (r = -0.9820, R2 = 0.9643), and for the reference 60089 (r = -0.9960, R2 = 0.9932). TPC/FRAP (mM TEAC/100 mL) for 60086 (r = 0.8096, R2 = 0.6554); reference 60088 presents an inverse and strong correlation with a 100% relationship at a linear level of both variables. TFC/DPPH for 60085 (r = -1.0, R2 = 1.0), 60084 (r = -0.9934, R2 = 0.9868), and 60090 (r = 0.9586, R2 = 0.9190). TFC/FRAP for 60087 (r = -0.9798, R2 = 0.9601) and 60090 (r = 0.9750, R2 = 0.9506) is higher compared to the reference wines 60088 and 60089. It is concluded that the samples of artisanal wines have the same antioxidant activity that would be due to their polyphenolic and flavonoid compounds, and the glyphosate content is below the maximum permissible limit values (0.1 mg/L). |
