Problems solved by technology

At present, in addition to fresh pork liver, the market share of processed products (such as pork liver pate) using it as raw material is very small, which cannot meet the needs of consumers. Therefore, the processing and utilization of pork liver has broad development prospects
[0003] Although traditional canned pork liver pate has a unique flavor of pork liver, the processing technology is not perfect, it has obvious bitter taste of pork liver, and the fat floats up seriously. Affects the sensory quality of the finished product
In addition, although the current patent on pig liver sauce products has improved the production process and adjusted the product formula to make its functional characteristics more prominent, it has not proposed a good solution to the above problems, and the product has a short storage period and cannot be stored for a long time at room temperature. put, poor product preservation
