This invention discloses a low-
phosphorus emulsified sausage based on the synergistic effect of modified
yeast protein and broad bean fibrous
protein, and its preparation method, belonging to the field of meat
processing technology. The sausage raw materials, by
mass, include meat, water, salt, modified
yeast protein, broad bean fibrous protein,
curdlan gum, and a small amount of complex
phosphate. The modified
yeast protein is prepared by pH shift-
phosphorylation synergistic method, and the broad bean fibrous protein is prepared by acid-heat induction from broad bean protein. During preparation, a colloidal dispersion is first obtained through low-temperature premixing, followed by stepwise chopping and emulsification to obtain minced meat. The product is then stuffed, low-temperature shaped, high-temperature cooked, and cooled to obtain the final product. This invention utilizes two modified proteins and
curdlan gum to form a ternary interpenetrating gel network, significantly reducing the amount of
phosphate used, to only about half that of traditional products. The resulting sausage exhibits a cooking loss of 3.5%~4.5%, a
water holding capacity of 92%~95%, and superior
gel strength compared to traditional high-
phosphorus products. It has a chewy texture, is juicy, and the
processing technology is simple and easily scalable for industrial production.
