Embodiment 1

[0021] Preparation of Structured Grease

[0022] (1) Provide palm stearin, the proportion of palmitic acid in the total fatty acids is 76.5%, the content of palmitic acid in the Sn-2 position is 60.6%, the Sn-1 and 3 positions are oleic acid and the Sn-2 position is palmitic acid The triglyceride content is 3.3%. Wherein, "Sn-2 palmitic acid content" refers to the content of palmitic acid at the Sn-2 position accounting for all the fatty acids at the Sn-2 position. The following examples all use the same concept and will not be repeated hereafter.

[0023] (2) Put 500 g of palm stearin, 250 g of potassium palmitate and 2.5 g of water into a flask, stir and raise the temperature to 160° C. and keep it constant. After continuing the reaction for 10 hours, remove soap by centrifugal filtration to obtain grease A.

[0024] (3) Mix 400g of oil A with 400g of oleic acid, place in a flask, stir and heat up to 60°C and keep it constant, add 10g of hexane and 80g of Sn-1,3 specific ...

Embodiment 2

[0048] Preparation of Structured Grease

[0049] (1) Provide palm stearin, whose palmitic acid accounts for 76.5% of the total fatty acids, the content of palmitic acid at the Sn-2 position is 61.3%, the Sn-1 and 3 positions are linolenic acid and the Sn-2 position is palmitic acid The triglyceride content is 0.2%.

[0050] (2) Put 2000 g of palm stearin, 2000 g of sodium palmitate and 10 g of water into a flask, stir and raise the temperature to 160° C. and keep it constant. After 12 hours of continuous reaction, soap is removed to obtain grease A.

[0051] (3) Mix 1000g of oil A with 3000g of linolenic acid, place in a flask, stir and heat up to 60°C and keep it constant, add 30g of cyclohexane and 200g of Sn-1,3 specific lipase, and react for 10 hours (directed transesterification , the same below), to obtain mixed oil B.

[0052] (4) Refining the mixed oil B. The refining steps include but are not limited to: filtering to remove lipase, dry fractionation to remove free f...

[0067] Preparation of Structured Grease

[0068] (1) Provide palm stearin, the proportion of palmitic acid in the total fatty acids is 79.0%, the content of palmitic acid in the Sn-2 position is 66.0%, the Sn-1 and 3 positions are arachidonic acid and the Sn-2 position is palmitic acid Acid triglyceride content is 0%.

[0069] (2) Put 7,500g of palm stearin, 15,000g of methyl palmitate, and 750g of lipase in a container, stir and heat up to 65°C and keep it constant. After 12 hours of continuous reaction, dry fractionation removes fatty acid methyl ester to obtain oil a.

[0070] (3) Take 5000g of fat A and 20000g of arachidonic acid, mix them in a container, stir and heat up to 70°C and keep it constant, add 200g of octane and 2000g of Sn-1,3 specific lipase, and react for 8 hours (directed transesterification , the same below), to obtain mixed oil B.

[0071] (4) Refining the mixed oil B. The refining steps include but are not limited to: filtering to remove lipase, dry...

Abstract

The invention relates to structural fat. The structural fat is prepared from vegetable oil in a synthesis manner, and the content of palmitic acids of Sn-2 bits is not lower than 70%. The structural fat sources from the vegetable oil, requirements of food products regulations are met, and application range is wide. Furthermore, the content of the palmitic acids of the Sn-2 bits in the structural fat is not lower than 70%, the structural fat contains triglyceride of which Sn-1, 3 bits are unsaturated fatty acids and Sn-2 bits are palmitic acids, and the ratio of triglyceride accounts for the ratio of total triglyceride by 60% at least. The nutritional structure of the structural fat is quite close to that of breast milk, and the structural fat can be absorbed by human bodies easily.

Description

technical field [0001] The invention relates to a structured oil, in particular to a structured oil derived from vegetable oil. The present invention further relates to a special diet comprising structured fats. Background technique [0002] Triglycerides are the main fats and oils ingested by humans. Modern nutrition has confirmed that during the process of digesting triglycerides, the human body will preferentially hydrolyze the fatty acids at positions Sn-1 and 3 to form Sn-2 monoglycerides and a large amount of free fatty acids. These free fatty acids will undergo two reactions in the body: 1. be absorbed by itself; 2. be excreted after reacting with other substances in the body. Compared with free unsaturated fatty acids, free saturated fatty acids have a slower absorption rate and are more likely to react with calcium to form insoluble calcium soap, which is then excreted. Therefore, compared with triglycerides that produce free saturated fatty acids, triglycerides ...
