, due to its saprophytic nature, can extract nutrients and bioactive compounds from the substrate on which it is grown. This study aimed to assess the effect of adding spent coffee grounds (SCG) and potato peel (PPW) in the wheat straw substrate formulation to grow over the production indicators, physicochemical, techno-functional, total chemical compounds, and antioxidant properties. Treatments were described as follows: T1, wheat straw at 100%; T2, wheat straw at 80% + 10% of SCG + 10% of PPW; T3, wheat straw at 70% + 15% of SCG + 15% of PPW; T4, wheat straw at 60% + 20% of SCG + 20% of PPW. After . growth, non-differences were found in production indicators for T1-T4, including biological efficiency, production rate, and yield. With respect to . dried powders, T1-T4 showed pH values near neutrality concerning soy protein (SP), and the color samples were beige. Also, T2 and T3 exert higher water-holding (WHC) values, while T1-T4 exert higher oil-holding (OHC) and emulsifying capacity (EC) values concerning SP, in dependence on the growth substrate. T1-T4 showed lower swelling (SC) and T1-T3 lower gelling capacity (GC) values. Regarding total chemical compounds and antioxidant properties of . extracts, growth substrate and solvent extraction have an effect on metabolite content and antiradical and reducing power properties. The multivariate analysis revealed that T2 water extracts exert the highest total tannin (TTC) and protocatechuic acid contents (PAC), as well as the highest antiradical (RCSA) and reducing power (RPA) values. In conclusion, this study demonstrated that using SCG and PPW as a partial substitute for substrate (what straw) enhances the physicochemical, techno-functional, and antioxidant activity of . .
由于其腐生性质，[具体事物未提及]能够从其生长的基质中提取营养物质和生物活性化合物。本研究旨在评估在小麦秸秆基质配方中添加废弃咖啡渣（SCG）和土豆皮（PPW）对生产指标、理化性质、技术功能、总化学成分和抗氧化性能的影响。处理方式如下：T1，100%小麦秸秆；T2，80%小麦秸秆 + 10% SCG + 10% PPW；T3，70%小麦秸秆 + 15% SCG + 15% PPW；T4，60%小麦秸秆 + 20% SCG + 20% PPW。在……生长后，T1 - T4的生产指标，包括生物效率、生产率和产量，未发现差异。关于……干粉，T1 - T4与大豆蛋白（SP）相关的pH值接近中性，颜色样本为米色。此外，T2和T3具有较高的持水（WHC）值，而T1 - T4与SP相关的持油（OHC）和乳化能力（EC）值较高，这取决于生长基质。T1 - T4显示出较低的溶胀（SC），T1 - T3显示出较低的胶凝能力（GC）值。关于……提取物的总化学成分和抗氧化性能，生长基质和溶剂萃取对代谢物含量以及抗自由基和还原能力特性有影响。多变量分析表明，T2水提取物的总单宁（TTC）和原儿茶酸含量（PAC）最高，以及抗自由基（RCSA）和还原能力（RPA）值最高。总之，本研究表明，使用SCG和PPW作为基质（小麦秸秆）的部分替代品可增强……的理化性质、技术功能和抗氧化活性。
