Embodiment 1

[0032] Embodiment 1: the preparation of ionic liquid and the method for using it to extract cod roe protein

[0033] An ionic liquid is mainly prepared from the following raw material components: stirring and rotating L-carnitine and tartaric acid at a molar ratio of 1:1.

[0034] The method for extracting cod roe protein by using the above-mentioned ionic liquid comprises the following steps:

[0035] Mix 10g cod roe with 30g of the above-mentioned ionic liquid, prefreeze and thaw, the temperature of prefreezing is -20°C, and the temperature of thawing is 25°C, the process of prefreezing and thawing is repeated 6 times, and the thawed mixture Break the wall, stir for 15min at a speed of 6000r / min, then centrifuge for 15min at a speed of 10000r / min, take the supernatant and filter, take the filtrate, and the resulting filtrate contains cod roe protein, in- Store at 20°C to 4°C.

Embodiment 2

Abstract

The invention discloses an ionic liquid and a method for extracting codfish roe protein by utilizing the same. The ionic liquid is mainly prepared from the following raw material components: alkaloidand organic acid; the organic acid is selected from at least one of tartaric acid, salicylic acid, succinic acid and benzoic acid; and the molar ratio of the alkaloid to the organic acid is (1-12):(0.2-3). The method for extracting the codfish roe protein by utilizing the ionic liquid comprises the following steps: mixing codfish roes with an aqueous solution of the ionic liquid, performing pre-freezing and unfreezing, performing wall breaking, stirring and centrifuging on the unfrozen mixture, and filtering a supernate. The ionic liquid has a very good extraction effect on codfish roe proteinand high extraction efficiency, and the extracted protein has high biological activity and high stability and is easy to store.

Description

technical field [0001] The invention relates to an ionic liquid, in particular to a method for using the ionic liquid to extract animal protein, in particular to an ionic liquid and a method for using it to extract cod roe protein. Background technique [0002] Animal protein has high nutritional value, and fish protein is a very important animal protein. In China, cod is mainly produced in the Bohai Sea, the Yellow Sea and the northern part of the East China Sea. It is one of the marine economic fish species produced in the northern coast. The cod meat is delicious and nutritious, and can promote blood circulation and eliminate addiction; the swim bladder can replenish blood and stop bleeding; cod bones can cure athlete's foot; Cod pancreas contains a large amount of insulin; cod liver can be used to extract cod liver oil, and sturgeon roe is of high value, but it is not fully utilized. It is often simply eaten, resulting in insufficient utilization of sturgeon roe, and eve...
