Description
Technical field
The present invention relates to a kind of special diet, especially a kind of containing 1, the special diet of 3-bis-unsaturated fatty acid-2-Palmic acid Structure grease.
Background technology
Triglyceride is the main oils and fats composition of human consumption, and modern nutriology it turned out, and human body, during devils brew three ester, is understood selective hydrolysis Sn-1, the fatty acid on 3, formed Sn-2 monoglyceride and substantial amounts of free fatty.These free fatties there will be two kinds of reactions in vivo: 1, by own absorption；2 are discharged after other substance reactions internal.Compared with free unsaturated fatty acid, free satisfied fatty acid absorption rate is slow, it is easier to reacts with calcium, forms insoluble soap calcium, and then be excreted.Accordingly, with respect to the triglyceride of the free satisfied fatty acid of generation, the triglyceride producing free unsaturated fatty acid is more conducive to the absorption of human body.In breast milk, the fat of about 98% is presented in triglyceride, and wherein the content of Palmic acid (C16:0, satisfied fatty acid) accounts for 20-25%, and oleic acid (C18:1, unsaturated fatty acid) content accounts for 30-38%.Most Palmic acid is distributed in the Sn-2 position of triglyceride, and oleic acid is then mainly distributed on Sn-1 and Sn-3 position.At present, the component content of the baby formula milk powder on market and breast milk relatively, but, substantial amounts of human trial and zoopery have confirmed that, the absorption of human milk fat is better than baby formula milk powder, and one of them major reason is that the triglyceride structure of this uniqueness in breast milk.For some gastrointestinal function weakling group, the triglyceride structure of this uniqueness in breast milk can be simulated, make special diet and alleviate its intestines and stomach burden, ensure enough nutrition simultaneously.
The inspiring of triglyceride structure by uniqueness this in breast milk, part manufacturer has been had to utilize the modification to natural oil to produce the Structure grease of simulation breast milk at present, and be added in baby milk powder and special diet, this not only can improve human body to fat and the absorption efficiency of calcium, the hardness of feces can also be reduced, reduce constipation and ileac probability of happening.The feature of this Structure grease is: the fatty acid on Sn-2 position is mainly Palmic acid, and the fatty acid on 1,3 is mainly unsaturated fatty acid (unsaturated
Fatty acid, UFA).
(+)-2,3-Epoxy-1-propanol (ester), chloropropyl alcohol (ester) are the first kinds of pollution matters begun to focus on the most in the world, and wherein chloropropyl alcohol (ester) can be converted by (+)-2,3-Epoxy-1-propanol (ester).Both pollutant have genetoxic and Toxicity of Kidney, are possible carcinogens.Within 2009, Japanese Kao company stops the sale of Econa Series Oil fat prod, it is simply that because (+)-2,3-Epoxy-1-propanol (ester) and the too high levels problem of chloropropyl alcohol (ester).
1-chloro-1,2-propylene glycol has been identified as the accessory constituent of the processing induction in the fat that refines completely and oil.They are mainly formation in deodorising step.At least demonstrate that two kinds of isomers of formation, i.e. 2-chlorine-1,2-propylene glycol and 3-chlorine-1,2-propylene glycol, and the latter are main isomers.All completely refined fat and oil all contain 3-chloro-1,2-propylene glycol.Although being not entirely understood its definite forming process, but the processing temperature of having been observed that, particularly steam deodorization processing tool has a significant impact: temperature is the highest, and the amount of the 3-chlorine-1,2-propylene glycol found in vegetable oil is the highest.
Summary of the invention
It is an object of the invention to provide the special diet that a kind of nutritional labeling is high and edible safety is high.
For achieving the above object, the present invention provides a kind of special diet, this special diet contains 1, the Structure grease of 3-bis-unsaturated fatty acid-2-Palmic acid, in described Structure grease, 3-chlorine-1,2-propylene glycol is not higher than 1.8mg/kg with the total content of (+)-2,3-Epoxy-1-propanol, and the content of 3-chlorine-1,2-propylene glycol is not higher than 1.2mg/kg.
Further, in described Structure grease, 3-chlorine-1,2-propylene glycol is not higher than 0.5mg/kg with the total content of (+)-2,3-Epoxy-1-propanol, and the content of 3-chlorine-1,2-propylene glycol is not higher than 0.4mg/kg.
Containing containing 1 in the special diet of the present invention, the Structure grease of 3-bis-unsaturated fatty acid-2-Palmic acid, therefore nutritional labeling is high.Further, the content of the 3-chlorine-1,2-propylene glycol of this Structure grease is relatively low, and 3-chlorine-1,2-propylene glycol is relatively low with the total content of (+)-2,3-Epoxy-1-propanol, and therefore edible safety is high.
