Embodiment 1

[0036] 1. Extract fat from Mekong Delta catfish:

[0037] Wash the basa catfish and tracatfish in the Mekong Delta, remove the fish fillets, crush the remaining raw materials, and then conduct continuous cooking in a continuous cooking machine, press filter, remove residue and heat with steam After 20-60 minutes, the obtained crude fat is centrifuged, dehydrated through a flash evaporation process, and finally refined to obtain the finished product of Mekong Delta catfish fat.

[0038] The refining described in the examples of the present invention adopts mature technology, and the specific steps include: degumming, deacidification, decolorization and deodorization. The deodorization stage is carried out under the conditions of a temperature of 240° C., a residence time of 65 minutes, and a vacuum degree of 2.3 mbar.

[0039] 2. Oil fractionation:

[0040] Heat the Mekong Delta catfish fat obtained in the above steps to 55-60°C, stabilize for 20 minutes, then cool down to 30...

Embodiment 2

[0047] 1. Extraction of Mekong Delta catfish fat:

[0048] Wash the basa catfish and tracatfish in the Mekong Delta, cook them continuously, press filter, remove the slag, and heat them with steam for 20-60 minutes, then centrifuge the obtained crude fat, and then dehydrate through the flash evaporation process , and finally refined to obtain the Mekong Delta catfish fat product.

[0049] 2. Preparation of mixed fatty acids:

[0050] Mix canola oil, soybean oil and coconut oil in a weight ratio of 6:2:2, heat up to 100°C while stirring, keep for 20 minutes, and dehydrate. First add lye for saponification, separate glycerol, then add hydrochloric acid for acidification to obtain mixed fatty acids.

[0051] 3. Enzymatic transesterification:

[0052] The weight ratio of Mekong Delta catfish fat to mixed fatty acids is 1:1, the amount of lipase LIPOZYME RMIM added is 5% of the fat weight, the reaction temperature is 55° C., and the transesterification reaction time is 4 hours. ...

Embodiment 3

[0054] 1. Extract fat from Mekong Delta catfish:

[0055] See Example 1 for specific extraction steps.

[0056] 2. Oil fractionation:

[0057] See embodiment one for specific fractionation steps.

[0058] 3. Preparation of mixed fatty acid ethyl esters:

[0059] Mix corn oil, linseed oil and coconut oil in a weight ratio of 6:2:2, heat up to 100°C while stirring, keep for 20 minutes, and dehydrate. Add 1% catalyst KOH of oil weight into ethanol (the molar ratio of ethanol to oil is 6:1), and stir to dissolve. After the grease is cooled to 60°C, add the catalyst-added ethanol solution to start the reaction for 3 hours. Add citric acid solution (the molar ratio of citric acid to KOH is 1:1) and wash with water. Vacuum pump at 60°C for 1-2 hours. The final product is mixed fatty acid ethyl ester.

[0060] 4. Enzymatic transesterification:

[0061] The weight ratio of the fractionation liquid component of the Mekong Delta catfish to the mixed fatty acid ethyl ester obtaine...

Abstract

The invention provides pangasianodon gigas lipid, application and a method for preparing breast milk lipid substitutes thereof. The lipid from the pangasianodon gigas is catfish fat or a fractionation liquid component thereof extracted from whole fish of the pangasianodon gigas or other positions after fillets are removed. The pangasianodon gigas lipid is used for preparing the breast milk lipid substitutes. The palmitic acid content on the Sn-2 position in the breast milk lipid substitutes prepared by the pangasianodon gigas lipid is relatively high, which is accordant to that on the Sn-2 position in the breast milk lipid, namely reaches over 60 percent. Meanwhile, AA and DHA exist in the pangasianodon gigas fat or the fractionation liquid component thereof, so the breast milk lipid substitutes does not need the extra AA and DHA or only needs to add a small quantity of the AA or DHA .

Description

technical field [0001] The invention belongs to the field of edible fats and oils, and in particular relates to fats and oils derived from catfish in the Mekong River Delta and its application in preparing breast milk fat substitutes. Background technique [0002] Breast milk is the perfect food for a baby's growth and development. Therefore, WHO advocates breastfeeding for at least 6 months after birth to ensure the growth and development of the baby, improve immunity and prevent infectious diseases. Breast milk contains about 4-4.5% fat, 98% of which are triglycerides. The types of fatty acids in breast milk are complex. Saturated fatty acids include medium-chain, medium-long-chain and long-chain saturated fatty acids, such as lauric acid (5-7%), palmitic acid (20-24%), stearic acid (7.1-9%) ); monounsaturated fatty acids include oleic acid (31-38%), palmitoleic acid (2.5-3.8%), n-3 polyunsaturated fatty acids except containing linoleic acid; n-3 polyunsaturated fatty ac...
