摘要： The objective of this study was to develop an efficient method for decolorizing and deodorizing Asian swamp eel (ASE) hydrolysate. At an activated carbon (AC) dosage of 0.5 % and pH 4.0, insoluble peptides from trichloroacetic acid (TCA), which have poor antioxidant activity, were effectively removed. Meanwhile, other nitrogenous fractions with better antioxidant activity were retained, achieving a decolorization rate of 74.02 +/- 0.38 %. Orthogonal partial least squares discriminant analysis (OPLS-DA) successfully distinguished the solid phase microextraction gas chromatograph-mass spectrometery (SPME-GC-MS) results of samples treated with different deodorization methods (ASE stock hydrolysate, AC treatment, AC + complex bacteria, AC + yeast, and AC + cyclodextrin). A total of 22 differential volatile compounds with variable importance projection (VIP) values greater than 1 were identified. The combination of AC treatment and cyclodextrin encapsulation effectively removed undesirable odors, enhancing the sensory quality and market competitiveness of the final product.
