Abstract: Orthogonal array design method was used to optimize the industrial formulation of quick-frozen sweet and sour spareribs and to investigate the effects of various processing conditions on sensory quality. Meanwhile, the formulation of seasoning sauce was optimized by uniform experimental design and quadratic polynomial regression analysis. The optimal quick-frozen sweet and sour sparerib formula was 500 g of meat, 50 g of sugar, 10 g of soy sauce, 70 g of vinegar, and 40 g of cooking wine. The optimal processing conditions were 10 min precooking, 10 min curing, 3 min deep frying, 15 min high fire cooking. The optimal seasoning sauce was composed of 50 g of meat, 35 g of oil, 15 g of sugar, 5.98 g of soy sauce, 10.71 g of cooking wine, 30.77 g of vinegar, 71.93 g of water, and 0.45 g of salt.

Key words: sweet and sour spareribs, quick-frozen dish, uniform experimental design, sensory evaluation
