The invention discloses a preparation method of a shepherd's purse sausage. The preparation method comprises the following steps: S1, preparing the following raw materials in parts by weight: 35-45 parts of chicken, 0.7-1.2 parts of table salt, 0.2-0.5 part of
phosphate, 0.0015-0.002 part of
sodium nitrite, 12-18 parts of
ice water, 15-20 parts of fatlining, 0.2-0.6 part of
carrageenan, 0.1-0.2 part of spiceries, 0.8-1.5 parts of
protein isolate, 8-13 parts of cassava
starch, 8-15 parts of shepherd's purse, 3-4 parts of white granulated
sugar, 0.05-0.1 part of
ethyl maltol and 0.3-0.8 part ofmonosodium glutamate; S2,
mincing the chicken and the fat lining for later use; S3, dissolving a
pigment in the
ice water, uniformly stirring the
ice water with the
minced chicken and fat lining, andadding the table salt, the
phosphate and the
sodium nitrite; S4, performing stirring in vacuum, and performing
vacuum pumping until the vacuum degree is -6 to -8 MPa, wherein the stirring time is notless than 8 minutes; S5, taking the mixture out of the pot, backing with ice water and delivering into a high-temperature warehouse for
pickling to obtain stuffing; S6, adding the spiceries, the residual ice water, the white granulated
sugar, the
carrageenan,
ethyl maltol,
monosodium glutamate,
protein isolate and the shepherd's purse, performing uniform stirring, adding the cassava
starch, maintaining the conditions under the vacuum degree of -6 to -8 MPa for 2-3 minutes and taking the material out of the pot; and S7, performing filling,
drying,
steaming, cooling and packaging processes.
