Embodiment 1

[0058] A processing method for adding sheep plasma protein instant fish tofu, the process flow chart is as follows figure 1 shown, including the following steps:

[0059] Thaw frozen freshwater surimi at 4°C to a semi-thawed state where it can be cut into pieces, but there is still some crushed ice in the middle. Put the half-thawed freshwater surimi into a chopping machine, set the rotating speed of the chopping knife shaft to 1500r / min, and empty chop for 4.0min to obtain empty chopped surimi. Add 2.5% non-iodized salt to the surimi after air chopping, and chop and mix for 5.0 min under the condition that the rotating speed of the cutter shaft is 1500 r / min, so as to obtain salt-cut surimi. After chopping and mixing for 40s each time, the chopping machine stops working for 10s, and the temperature of the surimi material is kept below 5°C. Add 2% goat plasma protein powder, 1% curdlan gum, 0.5% konjac gum, 4% soybean protein isolate, and 0.1 U / g fish with surimi quality to ...

Embodiment 2

[0061] A processing method for adding sheep plasma protein instant fish tofu, comprising the following steps:

[0062] Thaw frozen freshwater surimi at 4°C to a semi-thawed state where it can be cut into pieces, but there is still some crushed ice in the middle. Put the half-thawed freshwater surimi into a chopping machine, set the rotating speed of the chopping knife shaft to 2000r / min, and empty chop for 3 minutes to obtain empty chopped surimi. Add 2.5% non-iodized salt to the minced surimi after air chopping, and cut and mix for 4.0 min under the condition that the rotating speed of the cutter shaft is 2000r / min, so as to obtain minced surimi with salt. After chopping and mixing for 45s each time, the chopping machine stops working for 10s, and the temperature of the surimi material is kept below 5°C. Add 2.5% goat plasma protein powder, 0.8% curdlan gum, 0.75% konjac gum, 4.5% soybean protein isolate, and 0.25 U / g of fish surimi to the salted surimi. Grind, chopped and ...

Embodiment 3

[0064] A processing method for adding sheep plasma protein instant fish tofu, comprising the following steps:

[0065] Thaw frozen freshwater surimi at 4°C to a semi-thawed state where it can be cut into pieces, but there is still some crushed ice in the middle. Put the half-thawed freshwater surimi into a chopping machine, set the rotating speed of the chopping knife shaft to 2500r / min, and chop it in a vacuum for 2 minutes to obtain the surimi in a vacuum. Add 2.5% non-iodized salt of the raw material weight of the surimi after empty chopping to carry out salt chopping, chopping and mixing for 3 minutes under the condition that the rotating speed of the cutter shaft is 2500r / min, and obtain the salt-cut surimi. After chopping and mixing for 50s each time, the chopping machine stops working for 10s, and the temperature of the surimi material is kept below 5°C. Add 3% goat plasma protein powder, 1% curdlan gum, 0.5% konjac gum, 8% soybean protein isolate, and 0.5 U / g fish wit...

Abstract

The invention relates to instant fish tofu containing sheep plasma protein and a processing method of the instant fish tofu. The method comprises the following steps: firstly, adding trisodium citrateinto sheep blood, then performing centrifuging, collecting sheep plasma protein obtained by separation, performing freeze-drying to obtain sheep plasma protein powder, taking minced freshwater fish as a raw material, and performing unfreezing, mixing, chopping, heating, forming, frying, sterilizing and cooling to obtain the instant fish tofu. In the invention, the addition amount of the sheep plasma protein powder is 2-3%, the addition amount of iodine-free salt is 2-3%, and konjac glucomannan, curdlan, soy isolate protein, glutamine transferase and the like are added, so that the product hasrelatively high gel strength and water binding capacity, tastes good, and is convenient and instant. The product quality is guaranteed, the requirements of consumers for health, convenience and deliciousness of modern food are met, sheep blood can be fully utilized, instant minced fillet products are enriched, and the market prospect is wide.
