The present investigation was aimed at evaluating the impact of earthworm grazed and biofortified spent mushroom substrate (SMS) on natural antioxidant and nutritional properties of tomato. Results of the investigation reveal that earthworm grazing and bio-fortification led to significant improvement in the physico-chemical properties of fresh SMS and its application increased the accumulation of natural antioxidants and mineral content in tomato as compared to either biofortified SMS or fresh SMS. In particular, the earthworm grazed, biofortified SMS (EGTHB-SMS) was found to inhibit lipid peroxidation and protein oxidation with significant increase in total polyphenol and flavonoid content in tomato. Further, it increased Fe/Fe chelating activity, superoxide anion radical scavenging activity compared to other treatments. The results thus suggest an augmented elicitation of natural antioxidant properties in tomato treated with EGTHB-SMS, resulting in a higher radical scavenging activity, that is highly desirable for human health. In addition, the use of SMS to enhance the nutritional value of tomato fruits becomes an environment friendly approach in sustainable crop production.
本研究旨在评估蚯蚓采食和生物强化后的废菌糠(SMS)对番茄天然抗氧化剂及营养特性的影响。研究结果表明,蚯蚓采食和生物强化显著改善了新鲜SMS的理化性质,并且与生物强化后的SMS或新鲜SMS相比,其应用增加了番茄中天然抗氧化剂的积累和矿物质含量。特别是,发现蚯蚓采食的生物强化SMS(EGTHB-SMS)可抑制番茄中的脂质过氧化和蛋白质氧化,同时番茄中总多酚和类黄酮含量显著增加。此外,与其他处理相比,它增强了铁/铁螯合活性和超氧阴离子自由基清除活性。因此,结果表明用EGTHB-SMS处理的番茄中天然抗氧化特性得到增强,从而具有更高的自由基清除活性,这对人体健康非常有益。此外,利用SMS提高番茄果实的营养价值成为可持续作物生产中的一种环境友好型方法。
