Abstract This paper reports the production of fermented venison sausages with added fruits and vegetables by partial replacement of pork fat with emulsified vegetable oils, which have improved nutritional and health benefits. The processing properties were investigated and the process conditions were optimized. In order to find optimal conditions for fat substitution, we performed a comparative evaluation of the sensory properties and iodine value of fermented sausages with partial replacement of pork fat by different kinds of emulsified vegetable oils in different proportions. The effects of fermentation temperature, time and inoculum amount on the pH, iodine value and protein degradation of fermented sausages were examined by single factor method. Based on iodine value, the optimal levels for the three variables as well as fat substitution were determined by central composite design as 28℃,23.7 h, 0.94； and 70；, respectively. By correlation analysis, linear regression models were developed indicating moisture content and water holding capacity as a function of texture properties, respectively.
