specific Embodiment approach 1

[0019] Specific implementation mode one: this implementation mode utilizes the vacuum negative pressure method to extract the collagen protein liquid in the slaughtered fresh bone according to the following steps:

[0020] (1) After soaking, rinsing, cutting into pieces and freezing the fresh bone, put it into the extraction tank and seal it;

[0021] (2) Start the vacuum pump, open the valve connected to the buffer tank, make the buffer tank negative pressure, and turn off the vacuum pump when the vacuum degree is 14-75mmhg;

[0022] (3) Open the steam valve in the extraction tank, and close the intake valve when the temperature rises to 20-50°C and the pressure in the tank is 0.01-0.1MPA;

[0023] (4) Gradually open the valve of the buffer tank connected to the extraction tank, and pump the blood melted from the bone into the buffer tank. When the pressure of the buffer tank returns to 0, open the valve at the bottom, empty the buffer tank, and then close the connection betw...

specific Embodiment approach 2

[0035] Specific implementation mode two: this implementation mode utilizes the vacuum negative pressure method to extract the collagen protein mixture in the slaughtered and divided fresh bones according to the following steps:

[0036] 1. Pretreatment process: Vacuum negative pressure extraction method is used to remove blood water from fresh bones: the extraction tank is under positive pressure, and the buffer tank is under the condition of negative pressure and vacuum conversion to remove blood water from fresh bones. That is: a buffer tank is connected between the extraction tank and the vacuum pump. Under the conditions of positive pressure in the extraction tank and negative pressure in the buffer tank, when the instrument of the extraction tank shows a temperature of 20-60°C, the pressure is repeatedly boosted and released to make the blood flow at 60°C. Before solidification below ℃, it will be released with pressure. The specific steps are as follows:

[0037] (1) Tak...

Abstract

The invention discloses a process for extracting a collagen protein fluid from fresh slaughtered and segmented bones with a vacuum negative pressure method, and relates to a process for extracting a collagen protein fluid. The process adopts the vacuum negative pressure method, and the collagen protein fluid rich in the fresh bone is extracted under the condition of conversion between the positive pressure of an extracting tank and the negative pressure of a buffer tank. The extracted collagen protein fluid is an opaque milky-white to creamy-yellow suspension viscous fluid. The process has the advantages that the process is environment-friendly, and a physical method is adopted for extraction, so that secondary pollution cannot be produced during tailing treatment; and a substance which has concentration of 11-16% (w / w) of a solid content and protein of 45-88 (w / w) of the solid content can be extracted from different parts of sundry bones which cannot be sold at a high price in a slaughter house.

Description

technical field [0001] The invention belongs to the technical field of bioengineering, and relates to a process for extracting collagen liquid, in particular to a process for extracting collagen liquid in butchered and divided fresh bones by using a vacuum negative pressure method. Background technique [0002] National frozen pork reserves, meat export enterprises and other large-scale slaughterhouses with slaughtering and segmentation capabilities cut tens of thousands of tons of fresh bones every year. However, the level of comprehensive utilization is not high, and the due economic benefits have not been obtained. Except for leg bones used for extracting gelatin and cartilage used for extracting chondroitin sulfate, which can be sold at a higher price, part of the production and utilization of osteonin, other miscellaneous bones are basically simply steamed out of bone oil and used as feed additives. Among them, the protein extraction process mostly adopts the acid-bas...
