摘要: The impacts of four treatments, ultra-high hydrostatic pressure (UHP), high-pressure homogenization (HPH), combined UHP + HPH (U-H), and HPH + UHP (H-U), on bighead carp (Aristichthys nobilis) myofibrillar protein (BMP) structure, functional hydrolysis property to pepsin, and antioxidant activity of hydrolysates were investigated. All treatments led to increase in low-molecular-weight BMP, the BMP stability, and hydrophobic group exposure, but decrease in total sulfhydryl content and BMP particle size, thus resulting in increased hydrolysis and antioxidant capacity of enzymatic hydrolysates. U-H treated BMP exhibited the highest surface hydrophobicity (924.5 +/- 1.0), zeta potential absolute value (18.88 +/- 0.11 mV), hydrolysis degree (54.5 +/- 1.6%), and antioxidant activity, but the lowest alpha-helix (21.84 +/- 2.61%), intrinsic fluorescence spectrum intensity, total sulfhydryl (7.24 +/- 0.07 mu mol/g), and mean particle size (182.57 +/- 2.23 nm). Therefore, U-H might be a promising pretreatment to prepare bioactive peptide.
