Embodiment 1

[0037] Coconut oil, long carbon chain fatty acid (oleic acid and linoleic acid 2:1) are joined in the reactor with molar ratio 1:3, add 8wt% (reaction substrate mass ratio) immobilized lipase NS 40086, temperature keeps After reacting for 5 hours at 60°C and stirring at 300r / min, transfer the oil to a centrifuge tube and centrifuge at 2000r / min for 2 minutes to separate the lipase from the oil, neutralize with alkali to remove free fatty acids in the oil, and purify to obtain medium-long carbon Chain Triglyceride Composition 1.

Embodiment 2

[0039] Add palm kernel oil and pangasius oil (5:5wt%) to the reactor after mixing and melting, add 8% (reaction substrate mass ratio) lipase NS 40086, keep the temperature at 60°C, and stir at 300r / min After reacting for 8 hours, the oil was transferred to a centrifuge tube, centrifuged at 2000r / min for 2 minutes, and the lipase and oil were separated to obtain medium and long carbon chain triglyceride composition 2.

Embodiment 3

[0041] Palm kernel oil and fractionated lard (3.5:6.5wt%) were mixed and melted and added to the reactor, and 10% (reaction substrate mass ratio) lipase NS 40086 was added, and the temperature was kept at 60°C, stirring at 400r / min After reacting under conditions for 4 hours, the oil was transferred to a centrifuge tube, centrifuged at 2000r / min for 2 minutes, and the lipase and oil were separated to obtain medium-long-chain triglyceride composition 3.

Abstract

The invention provides a grease composition comprising medium-long carbon chain triglycerides. In composition of fatty acids, the contents of medium carbon chain fatty acids and long carbon chain fatty acids reach more than 99%, the content of short carbon chain fatty acids is less than 1%, and the mass ratio of the long carbon chain fatty acids to the medium carbon chain fatty acids is 1.2: 1 to3:1; in the sn-2 position, the grease composition contains the medium carbon chain fatty acids and the long carbon chain fatty acids; the content of saturated fatty acids in the sn2 position reaches more than 60%. In composition of the triglycerides, the mass ratio of the triglyceride containing a medium carbon chain fatty acid acyl group to all the triglycerides is 50-90%, the mass ratio of the triglyceride containing two medium carbon chain fatty acid acyl groups to all the triglycerides is 3-35%, and the mass ratio of the triglyceride containing three medium carbon chain fatty acid acyl groups to all the triglycerides is 0-10%. The grease composition has high oxidative stability, and the fat digestibility meets the needs of special populations such as infants.

Description

technical field [0001] The invention relates to an oil composition of medium and long carbon chain triglycerides, belonging to the technical field of oils and fats. Background technique [0002] Long-chain triglycerides (LCT) are usually rich in most edible oils and provide essential fatty acids for the normal development of the body. However, after LCT is decomposed, triglycerides are re-synthesized in the small intestinal villi cells. The newly synthesized triglycerides Combined with soluble protein, in the form of chylomicrons, it passes through the lymphatic system, enters the blood system through the thoracic duct, and finally transports to the liver. In the liver, it needs to rely on the carnitine carrier to enter the mitochondria and be oxidized and metabolized. Its hydrolysis rate and clearance rate in serum are relatively slow, especially for people with liver dysfunction, abnormal metabolism, infants and young children, its metabolism will be significantly affected...
