Abstract：
Functional constituents are the main concern in food production and consumption. Because foods rich in functional constituents have antioxidant capacity and are important in keeping consumers healthy. Pleurotus ostreatus is among foods rich in functional constituents. However, its functional constituents are affected by various factors. This study compared the antioxidant capacity of P. ostreatus grown on different substrates: straws of tef (Trt1), barley (Trt2), and wheat (Trt3), husks of faba bean (Trt4), and field pea (Trt5), sawdust (Trt6), and the mixture of the above with 1:1 w/w (Trt7). Trt7 had significantly higher radical scavenging activity (RSA) (73.27%), vitamin C (10.61 mg/100 g), and vitamin D (4.92 mg/100 g) compared to other treatments. Whereas the lowest values of RSA (44.24%), vitamin C (5.39 mg/100 g), and vitamin D (1.21 mg/100 g) were found in Trt2. The results indicated that mixed substrate may be a good growth substrate for functionally beneficial P. ostreatus and could be a promising source of natural antioxidants.
摘要：
功能性成分是食品生产和消费中的主要关注点。因为富含功能性成分的食品具有抗氧化能力，对保持消费者健康至关重要。平菇是富含功能性成分的食物之一。然而,其功能成分受多种因素的影响。本研究比较了在不同基质上生长的平菇的抗氧化能力：TEF（Trt1）的秸秆，大麦（Trt2），和小麦（Trt3），蚕豆壳（Trt4），和豌豆（Trt5），木屑(Trt6),和上述与1:1w/w(Trt7)的混合物。Trt7具有显著较高的自由基清除活性(RSA)(73.27%),维生素C（10.61毫克/100克），与其他治疗相比，维生素D（4.92mg/100g）。而RSA的最低值(44.24%)，维生素C（5.39毫克/100克），在Trt2中发现了维生素D（1.21mg/100g）。结果表明，混合底物可能是功能有益的平菇的良好生长底物，并且可能是天然抗氧化剂的有希望的来源。
