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
The present invention relates to a kind of Structure grease, especially a kind of Structure grease of vegetable oil source.The present invention further relates to a kind of special diet comprising Structure grease.
Background technology
Triglyceride level is the main grease composition of human consumption, and modern nutriology is verified, and human body is in the process of devil's brew three ester, and meeting selective hydrolysis Sn-1, the lipid acid on 3, forms Sn-2 mono-glycerides and a large amount of free fatty acidies.These free fatty acidies there will be two kinds of reactions in vivo: 1, by own absorption; 2, with after other substance reactions in body be discharged.Compared with free unsaturated fatty acid, free saturated fatty acid uptake rate is slow, and easier and calcium reacts, and forms insoluble soap calcium, and then is excreted.Therefore, relative to the triglyceride level producing free saturated fatty acid, the triglyceride level producing free unsaturated fatty acid is more conducive to the absorption of human body.
In breast milk, the fat of about 98% exists with the form of triglyceride level, and wherein the content of palmitinic acid (C16:0, saturated fatty acid) accounts for 20-25%, and oleic acid (C18:1, unsaturated fatty acids) content accounts for 30-38%.Most palmitinic acid is distributed in the Sn-2 position of triglyceride level, and oleic acid is then mainly distributed on Sn-1 and Sn-3 position, and in breast milk, the triglyceride structure of this uniqueness is called as 2-palmitin.At present, baby formula milk powder on market and the component content of breast milk relatively, but a large amount of human trials and experimentation on animals confirm all, the absorption of human milk fat is better than baby formula milk powder, and one of them major reason is just the triglyceride structure of this uniqueness in breast milk.The triglyceride structure of this uniqueness can not only ensure the absorption of infantile nutrition, and its digestion principle is equally applicable to some functions of intestines and stomach weakling group, can make special diet and alleviate its stomach burden, ensure enough nutrition simultaneously.
Be subject to the inspiration of the triglyceride structure of this uniqueness in breast milk, part manufacturer has been had to utilize the Structure grease modification of natural fats and oils being taken to production simulation breast milk at present, and added in baby milk powder and special diet, this not only can improve human body to assimilated efficiency that is fatty and calcium, the hardness of ight soil can also be reduced, reduce constipation and ileac probability of occurrence.The feature of this Structure grease is: the lipid acid on Sn-2 position is mainly palmitinic acid, Sn-1, and the lipid acid on 3 is mainly unsaturated fatty acids (unsaturatedfattyacid, UFA).
China Patent Publication No. is the application for a patent for invention of CN102757988A, disclose a kind of 1, the preparation method of 3-bis-oleic acid-2-palmitic acid three ester, comprise: glycerine and palmitinic acid are carried out esterification under catalyst action, obtained tripalmitin, then by tripalmitin and oleic acid or oleic acid ester 1, under 3 specific lipase effects, carry out transesterification reaction, thus obtain highly purified OPO.In this Structure grease, Sn-2 position palmitic acid content can reach 90%, but the Structure grease of this high Sn-2 position palmitic acid content, is by glycerine and palmitinic acid synthesis, can produces a large amount of soda acid wastes, be unfavorable for environmental protection in building-up process.On the other hand, the Structure grease that this method obtains does not meet the requirement of existing food relevant laws and regulations, and the scope of application can be extremely restricted.
China's publication number is the application for a patent for invention of CN102776077A, disclose a kind of preparation method of breast milk Structure grease, comprise plam oil palmitic acid content being greater than 50% and under catalyst action, carry out intramolecular rearrangement reaction, the triglyceride level that obtained Sn-2 position palmitic acid content is greater than 50%; Sn-2 position palmitic acid content is greater than 50% triglyceride level and mixed fatty acid or its nonglyceride 1, carry out transesterification reaction under 3 specific lipase effects, reaction product obtains breast milk Structure grease through aftertreatment.But be limited to preparation technology, in Structure grease obtained by this method, Sn-2 position palmitic acid content, generally about 50%, also exists a certain distance with the composition proportion of breast milk, therefore nutritive value needs further to be promoted.
Therefore, be necessary to develop a kind of more excellent technique, can improve Sn-2 position palmitic acid content in Structure grease, improve Sn-1 simultaneously, 3 are unsaturated fatty acids and Sn-2 position is the content of the triglyceride level of palmitinic acid.The Structure grease obtained by this technique, both with breast milk composition closer to, be beneficial to absorption of human body, food safety and laws and regulations requirement can be met again.
Summary of the invention
Main purpose of the present invention is to provide a kind of and meets food safety and laws and regulations requirement, be of high nutritive value and be beneficial to the Structure grease of absorption of human body.
Another object of the present invention is to provide a kind of and meet food safety and laws and regulations requirement, be of high nutritive value and be beneficial to the special diet of absorption of human body.
For realizing above-mentioned main purpose, the invention provides a kind of Structure grease, this Structure grease is by vegetables oil obtained by Material synthesis, and its Sn-2 position palmitic acid content is not less than 70%.
Further, comprise Sn-1 in said structure grease, 3 is unsaturated fatty acids and Sn-2 position is the triglyceride level of palmitinic acid, and the ratio that this triglyceride level accounts for total triglyceride level is not less than 60%, preferably 60%-80%.
Further, in said structure grease, unsaturated fatty acids is oleic acid, linolenic acid, arachidonic acid, docosahexenoic acid or timnodonic acid.
Further, said structure grease is liquid under 25 DEG C of conditions.
For realizing another object above-mentioned, the invention provides a kind of special diet, this special diet comprises Structure grease, and in this Structure grease, Sn-2 position palmitic acid content is not less than 70%.
Further, in above-mentioned special diet, Structure grease by vegetables oil obtained by Material synthesis.
Further, comprise Sn-1 in the Structure grease of above-mentioned special diet, 3 is unsaturated fatty acids and Sn-2 position is the triglyceride level of palmitinic acid, and the ratio that this triglyceride level accounts for total triglyceride level is not less than 60%, preferably 60%-80%.
