Abstract: The sensory and physicochemical properties of 43 traditional fermented soybean paste samples collected in Northeast China were determined in order to understand their quality characteristics. The physicochemical parameters including NaCl, acidity, water, amino nitrogen, reducing sugar, total acid, crude protein, and total free amino acids were correlated with sensory quality using SPSS 17.0 software. Principal component analysis and cluster analysis were carried out as well. The results showed that the best quality parameters of fermented soybean paste were 12–17.75 g/100 g NaCl, 70.35%– 78.56% moisture, 0.6–0.84 g/100 g amino nitrogen, 0.78–1.96 g/100 g total acid, and 6.06–9.83 g/100 g reducing sugar.

Key words: soybean paste, sensory quality, physicochemical properties, correlation analysis
