Embodiment 1

[0009] Take 20KG of thawed oyster meat and 0.072Kg of Na 2 CO 3 Put it into 23.928Kg of water to make a concentration of 0.3% Na 2 CO 3 water solution, put the oyster meat into the solution and soak for 10 minutes, then filter to remove Na 2 CO 3 solution; soak the soaked oyster meat in clean water for 3 minutes and repeatedly stir and rinse. When stirring, the action should be light to prevent the individual oysters from being broken, and rinse to remove the residual Na 2 CO 3 solution, that's it.

Embodiment 2

[0011] Take 50KG of thawed oyster meat and 0.75Kg of Na 2 CO 3 Put into 149.25Kg of water to make the concentration of 0.5% Na 2 CO 3 water solution, put the oyster meat into the solution and soak for 15 minutes, then filter to remove Na 2 CO 3 solution; soak the soaked oyster meat in clear water for 5 minutes and stir and rinse repeatedly. When stirring, the action should be light to prevent the individual oysters from being broken, and rinse to remove the residual Na 2 CO 3 solution, that's it.

Embodiment 3

[0013] Take 30KG of thawed oyster meat and 0.25Kg of Na 2 CO 3 Put into 62.25Kg of water to make the concentration of 0.4% Na 2 CO 3 Water solution, put the oyster meat into the solution and soak for 12 minutes, then filter to remove Na 2 CO 3 solution; soak the soaked oyster meat in clean water for 4 minutes and repeatedly stir and rinse. When stirring, the action should be light to prevent the individual oysters from being broken, and rinse to remove the residual Na 2 CO 3 solution, that's it.

Abstract

The invention relates to a method for debitterizing oysters. The method comprises the following steps: thawed oysters are selected and soaked in 0.1 to 0.5 percent Na2CO3 solution for 10 to 15 minutes, and the weight ratio of the oysters to the Na2CO3 solution is between 1 to 1.2 and 1 to 3; the mixed solution is filtered to remove the Na2CO3 solution; and the soaked oysters are soaked in fresh water for 3 to 5 minutes, and are washed repeatedly to remove residual Na2CO3 solution, thus the oyster is debitterized. The method has the advantages of simple technological process, complete debitterizing and enough delicate flavour.

Description

technical field [0001] The new invention relates to a method for improving the freshness of seafood, in particular to a method for debittering oysters. Background technique [0002] Oysters are distributed along the northern coast of my country. From May to June each year, the gonads of oysters are highly developed but have not reproduced. At this time, the soft body is the most fat. After ovulation, oysters are reduced in size, quality, and nutritional value. Therefore, most oyster processing companies purchase a large number of shelled products during the oyster fat season, and use ice-coated methods for single-freezing after shelling. , to supply oysters for subsequent processing and production. The quality of oysters will change due to long-term low-temperature refrigeration, resulting in bitter oysters. The bitterness is present in the viscera of oysters. At present, the method adopted is to cut open the internal organs for cleaning, which can effectively remove the ...
