Evaluation of the differences between low‐salt solid‐state fermented soy sauce and high‐salt diluted‐state fermented soy sauce in China: from taste‐active compounds and aroma‐active compounds to sensory characteristics

The present study aimed to determine the components related to sensory properties in soy sauce and to characterize the differences between low-salt solid-state fermented soy sauce (LSFSS) and high-salt diluted-state fermented soy sauce (HDFSS). The taste and aroma active components of 18 commercially available soy sauces (eight types of LSFSS and 10 types of HDFSS) were characterized. The relationship between these compounds, soy sauce samples, and sensory properties was modeled by partial least squares regression.
