[0234] The technique of obtaining krill oil and low-fat krill among the present invention

[0235] An embodiment of the relevant process method in the present invention is described below. figure 2 It is a flow chart of the process. This process apparently does not involve the use of organic solvents and / or supercritical liquid carbon dioxide.

[0236] Antarctic krill is caught from March to May, preferably in May, when the krill meat is plump. In the fishing grounds of the Orkney Islands, using a pumping system, the krill is captured when it is caught in the container of the factory ship. was alive and was dealt with immediately.

Abstract

The invention discloses a method for acquiring krill oil composition without using an organic solvent. The process comprises the following steps of: a) placing krills into a steamer, steaming for a period of time at certain temperature to denature protein contained in the krills, so as to obtain a primary solid product and a primary liquid product of the krills, wherein the condition that the primary solid product and the primary liquid product are formed into emulsion is avoided; b) under the condition that temperature is not less than 90 DEG C, taking out the primary solid product and the primary liquid product of the krills from the steamer container; c) separating the primary solid product from the primary liquid product; d) extracting the krill oil rich in neutral lipid from the primary liquid product; and e) squeezing the primary solid product to obtain squeezed liquid namely a secondary liquid product, and producing the krill oil rich in phospholipids from the liquid product. The method has the characteristic that no organic solvent is used in the whole separation and extraction steps. The invention also discloses composition of the krill oil produced by the method disclosed by the invention.

Description

technical field [0001] The present invention relates to the extraction of phospholipid oils using polyunsaturated fatty acids, docosahexaenoic acid and eicosapentaenoic acid in fractionated fractions of phospholipids, using astaxanthin and neutral lipids from food production lines, in the synthesis Krill meal is used for human health with low fat content. The present invention also discloses a procedure for obtaining dry complexes comprising phospholipids linked to docosahexaenoic acid and eicosapentaenoic acid in combination with krill oil, protein, and shrimp for human health green pigment. Background technique [0002] Krill are the equivalent of a group of small but abundant marine crustaceans in the suborder Krillidae, living in the pristine Antarctic Ocean, which is considered the forage base of all Antarctic ecosystems. Antarctic krill, especially those found in Antarctic and sub-Antarctic regions, consists of 11 krill species, becoming the main Antarctic krill and ...
