Embodiment 1

[0030] Embodiment 1, shorter centrifugation time

[0031] Ingredients: 100kg sheep blood, 10L 3.8% sodium citrate solution, 50kg ice water, 5.03g potassium dihydrogen phosphate, 881.84g dipotassium hydrogen phosphate, 2.13kg 37.5% calcium chloride solution.

[0032] 1. Blood collection: After slaughtering sheep that have passed the quarantine, fresh sheep blood is collected in a container that has been added with sodium citrate solution, mixed quantitatively and placed in a cold storage at 2°C to 8°C to cool down.

[0033] 2. Centrifugation: Use a centrifuge to centrifuge the sheep blood at 3000g and 4°C for 40 minutes, collect the upper layer liquid, put it into a storage tank and refrigerate at 4°C.

[0034] 3. Ingredients: According to the ingredient list, add 4°C ice water, potassium dihydrogen phosphate and dipotassium hydrogen phosphate to the feed liquid described in step 2, and mix well.

[0035] 4. Pre-coagulation: add calcium chloride solution to the feed liquid des...

Embodiment 2

[0039] Embodiment 2, suitable centrifugation time, suitable Ca 2+ concentration

[0040] In the centrifugation step, the centrifugation conditions are 3500g, 4°C, 60min, and the others are the same as in Example 1.

Embodiment 3

[0041] Embodiment 3, do not add ice water, lower Ca 2+ concentration

[0042] Ingredients: 100kg sheep blood, 10L of 3.8% sodium citrate solution, 5.03g of potassium dihydrogen phosphate, 881.84g of dipotassium hydrogen phosphate, 0.85kg of 37.5% calcium chloride solution.

[0043] 1. Blood collection: After slaughtering sheep that have passed the quarantine, fresh sheep blood is collected in a container that has been added with sodium citrate solution, mixed quantitatively and placed in a cold storage at 2°C to 8°C to cool down.

[0044] 2. Centrifugation: Use a centrifuge to centrifuge the sheep blood at 3500g and 4°C for 60 minutes, collect the upper layer liquid, put it into a storage tank and refrigerate at 4°C.

[0045] 3. Ingredients: add potassium dihydrogen phosphate and dipotassium hydrogen phosphate to the feed solution described in step 2 according to the ingredient list, and mix well.

[0046] 4~7. Same as embodiment 1.

Abstract

The invention relates to a processing method for goat blood tofu. The method comprises the following steps: taking anti-freezing goat whole blood as a raw material; taking upper plasma after centrifugal separation; respectively adding ice water, monopotassium phosphate, dipotassium phosphate and calcium chloride into the whole blood and the plasma; and finally obtaining the white goat blood tofu after steps of pH (Potential of Hydrogen) value adjustment, boxing, pre-setting, sealing, heat preservation, sterilization, cooling and inspection and the like. According to the method, the goat blood tofu is white by adding one centrifugal processing process; by controlling the adding amounts of water and Ca<2+> in a low-temperature condition, the product has more uniform characters; the texture and the quality of the product can be improved by adjusting the pH value through the potassium phosphates; meanwhile, table salt is prevented from being added in the processing process, so as to obtain low-salt, low-fat, high-protein and low-heat healthy food.

Description

technical field [0001] The invention relates to a processing method of sheep blood tofu, which belongs to the technical field of food processing. Background technique [0002] my country is the country with the largest slaughtering volume of mutton sheep in the world. Abundant by-products are produced during the slaughtering process. Blood is one of the by-products with a higher yield. In addition to a variety of functional protein components, it also contains 8 kinds of amino acids necessary for the human body (the content of lysine and leucine is particularly high), as well as trace elements such as calcium, iron, magnesium, phosphorus, potassium, vitamins, inorganic salts, Sugars and lipids, known as "liquid meat". [0003] At present, the utilization rate of sheep blood resources in our country is extremely low. Most mutton sheep slaughtering enterprises in my country directly discharge the blood, and only a few enterprises recycle it as blood meal for feed or for extract...
