Description
Technical field
The present invention relates to a kind of production method of human milk fat substituted grease.
Background technology
Breast milk is the optimum food that the mankind offer baby (especially neonate), it offers required various physiologically active speciality of baby and enough nutrition comprehensively, also offer the necessary but essential fatty acid that can not synthesize again in the body etc. of baby, with guarantee the baby birth can grow up healthy and sound, avoid in six months numerous disease invasion and attack etc. (list of references: 1. Zheng Jian celestial being. functional food [M] the 3rd volume, Beijing: the .1999 of China Light Industry Press; Wu Ke just, Yang Liansheng, Song Xianghua. the polyunsaturated fatty acid in the breast milk [J]. Chinese dairy industry .2000).The lipid that contains 3%-5% in the breast milk, 98% with lipid be glycerine trigalloyl ester, it is one of main nutrient matter in the breast milk, offer about 45% (0-6 month) and 30%-40% (7-12 month) of baby institute energy requirement, and for the growth of organs such as brain extremely important (list of references: 1. Zheng Jian celestial being. functional food [M] the 3rd is rolled up. Beijing: the .1999 of China Light Industry Press; 2.Robert G Jensen.Human Milk Lipids as a Model for InfantFormulas[J] .Lipid Technology.1998.3:34).
Owing to multiple reason, as the breast milk deficiency; Mother must work etc., causes and must replenish baby food to the baby.The design of the prescription of baby food undoubtedly can breast milk is contained nutritional labeling as reference object.With regard to fat, contain in the human milk fat 7% the middle carbochain fat aliphatic acid (C8:0-C12:0) of having an appointment, about 39% long carbochain saturated fatty acid (C14:0-C18:0) and＞50% unrighted acid (C18:1, C18:2 etc.), they are all bringing into play physiological function separately, alternative fats not only will be deferred to human milk fat on aliphatic acid is formed, and on sweet three ester structures, to simulate the unique texture of human milk fat as far as possible, because this structure is to baby's the important influence of digesting and assimilating.
Breast milk fatty acids composition and sweet three ester structure characteristics thereof are as follows:
Aliphatic acid in the breast milk forms that difference is very big with the different of region, ethnic group, diet with content, and the bibliographical information of forming about breast milk fatty acids is a lot, but because the difference that sample is originated also has certain difference on the final numerical value.The aliphatic acid of the breast milk that the women produces of western diet (the sample source comprises Canada, France, Holland, Germany and Australia) and non-western diet (Nigeria, Japan, Israel, the Sudan and China) is formed variant, sees Fig. 1; The aliphatic acid of living in the breast milk that the women produces of Chinese different regions is formed also variant, see Fig. 2 (list of references: Robert G Jensen.Lipids in human milk[J] .Lipids, 1999.34 (12): 1243).But human milk fat has some common features again, in the aliphatic acid composition, the oleic acid content maximum, unsaturated acids (mainly referring to C18:1, C18:2 and C18:3) mainly is distributed in Sn-1,3, but it is the most special with Sn-2 aliphatic acid, 40% saturated fatty acid is distributed in Sn-2, and the 60%-70% of palmitic acid (C16:0) in the Sn-2 position (list of references: 1.Robert GJensen.Human Milk Lipids as a Model for Infant Formulas[J] .Lipid Technology.1998.3:34; 2.Sheila M lnnis, Roger Dyer.Carloanne M Nelson.Evidence.That Palmitic Acid is Absorbedas sn-2 Monoacyglycerol from human milk by Breast-fed infant[J] .Lipids, 1994.29 (3): 54I).This characteristic distributions obviously is different from general vegetable oil (the Sn-2 position is mainly unsaturated acids).Just because of these characteristics are arranged, the sweet three ester types of fat are mainly Sn-USU type (U refers to unsaturated acids, and S refers to saturated acid) in the human milk, as Sn-OPO, and Sn-OPL (O refers to that oleic acid, P refer to that palmitic acid, L refer to linoleic acid) etc.
Characteristics that the following breast milk fatty acids of the characteristics of digesting and assimilating of human milk fat is formed and baby's self absorption characteristics are closely related.Human milk fat passes through the hydrolysis of stomach lipolytic enzyme earlier in infants, this kind of enzyme is for Sn-1,3 have certain selectivity, sweet three esters be hydrolyzed into free fatty and Sn-2 monoglyceride (list of references: Wu Kegang, Yang Liansheng, Song Xianghua. the polyunsaturated fatty acid in the breast milk [J]. Chinese dairy industry .2000), but not every aliphatic acid is the energy good absorption all, just is not so good as middle carbochain saturated acid (C8:0-C12:0) and unsaturated acids as long carbochain saturated ester (C14:0-C18:0) and easily digests and assimilates.This mainly is because long carbochain saturated acid forms stodgy soap in small intestine, disturbed the absorption (list of references: 1.Sheila M lnnis of baby to metal ion (as calcium ion) and aliphatic acid, Roger Dyer.CarloanneM Nelson.Evidence.That Palmitic Acid is Absorbed as sn-2Monoacyglycerol from human milk by Breast-fed infant[J] .Lipids, 1994.29 (3): 54I; 2.Michael L Gurr.Lipids and Nutrition[M] .England:Maypol Scientific Services.Si Marrys lsles of Scilly, 1995).Especially, in small intestine the absorption of free C16:0 very low, only 63%, and free C18:1 ω 9, C18:2 ω 9 can reach more than 90%.Because of free C16:0 easily and metal ion form insoluble calcium soap, thereby the loss (list of references: 1.Sheila M lnnis that causes calcium ion and energy etc., Roger Dyer.Carloanne M Nelson.Evidence.That Palmitic Acid is Absorbed as sn-2 Monoacyglycerol fromhuman milk by Breast-fed infant[J] .Lipids, 1994.29 (3): 54I).S.M.Innis (list of references: 1.Sheila M lnnis, Roger Dyer.CarloanneM Nelson.Evidence.That Palmitic Acid is Absorbed as sn-2Monoacyglycerol from human milk by Breast-fed infant[J] .Lipids, 1994.29 (3): 54I) proof Sn-2 monoglyceride is to digest and assimilate with the monoglyceride form in small intestine, and C16:0 is in the Sn-2 position, be that the palmitic acid monoglyceride is beneficial to the absorption of baby to fat, also influence the metabolism (list of references: Michael L Gurr.Lipids andNutrition[M] .England:Maypol Scientific Services.Si Marrys lsles ofScilly, 1995) of cholesterol simultaneously.This absorption pattern the sixth of the twelve Earthly Branches is through being confirmed, and the 1.2-1.4 that the absorption of being rich in the lard of C16:0 for the Sn-2 position as the baby is it after ester exchange at random doubly.In the human milk fat, long carbochain unsaturated acids (PUFA) mainly refer to oleic acid, essential fatty acid (linoleic acid, leukotrienes), DHA (C22:6) and AA (C20:4) etc. for infants growth and development have significance aliphatic acid (list of references: Wu Kegang, Yang Liansheng, Song Xianghua. the polyunsaturated fatty acid in the breast milk [J]. Chinese dairy industry .2000).The oleic acid content maximum, it can reduce the flowability and the metabolic capability (list of references: Paul Thomas ouinlan.Ian Christopher Chandler.Human milk fatsubstitutes.Australian patent office, (English) AI-A-10344/92 thereof of fusing point (＜38 ℃) the raising fat globule of sweet three esters.) picked-up of polyunsaturated acid grows up extremely importantly for infantile health, also have critical function at the normal function of keeping cell membrane and synthesizing activity aspect becoming to grade.Synthetic respectively AA and DHA in infants as leukotrienes and linoleic acid, and linoleic acid and arachidonic acid are present in brain tissue, optic nerve and the vision system in a large number, and best working condition can be provided.And (list of references: Robert G Jensen.Human Milk Lipidsas a Model for Infant Formulas[J] .Lipid Technology.1998.3:34) grown in the growth that can promote baby's nervous centralis.Again because linoleic acid and leukotrienes have the competition effect on dehydrogenase and carbochain prolongation enzyme, keep ratio balance between the two will determine the content of DHA and AA, among Fig. 2, the ratio of n-6PUFAs and n-PUFAs is about 2.88-6.8 in the human milk fat: 1, but according to " global standards of infant formula composition: suggestion is from European paediatrics gastrointestinal disease, the international expert group of hepatopathy and NI's tissue " (Global Standard for the Composition of InfantFormula:Recommendations of an ESPGHAN CoordinatedInternational Expert Group) (list of references: Koletzko B, Baker S, Cleghorn G, et al, Global standard for the composition of infantformula:Recommendations of ESPGHAN coordinated internationalexpert group.J Pediatr.Gastroenterol Nutr.2005; 41:584-599.), the suitable ratio of n-6PUFAs and n-PUFAs is 5-15: 1.
In human milk, can detect trans-fatty acid usually, its content is bigger, see Fig. 4 (list of references: Robert G Jensen.Lipids in human milk[J] .Lipids, 1999.34 (12): 1243).The mankind itself can not synthesize trans-fatty acid, and its source mainly contains three aspects: the fat of ruminant, meat and milk; Hydrogenated oil and fat (as margarine oil's wet goods); The deodorization wet goods.Trans-fatty acid content in trans-fatty acid in the human milk and wet nurse's the diet has certain correlation, can be expressed as Y=1.49+0.42X as the relation of the content (X) in the content (Y) of trans-fatty acid C18:0 in human milk and the wet nurse's diet.Trans-fatty acid can influence the metabolism of other unsaturated acids.When content of trans fatty acids in people's butterfat surpassed 10%, the linoleic acid plus linolenic acid content in the infants can reduce, and baby's growth also can be restricted.The content of trans acids in food has been subjected to paying close attention to widely, and some countries are more arranged, just put into effect trans-fatty acid content in the relevant laws and regulations regulation food in 2003 as Denmark.Therefore the trans acids in the baby food should be controlled at the low degree of trying one's best.
The seminar of n-6 that held in 1999 and n-3 essential fatty acid meals recommended amounts (Workshop on the Essentiality of and Recommended Dietary Intakes forOmega-6 and Omega-3 Fatty Acids), provided the suitable intake of n-6 and n-3 aliphatic acid in formula food/meals of baby, see Fig. 3 (list of references: Artemis P.Simopoulos, MD, Alexander Leaf, MD and Norman Salem, Jr, PhD.Workshop on the Essentiality of and Recommended Dietary Intakesfor Omega-6 and Omega-3 Fatty Acids.Journal of the AmericanCollege of Nutrition, Vol.18, No.5,487-489 (1999)).
The fat that uses in the baby food has following several at present;
(1) directly uses cow's milk fat.
Directly replace human milk fat with cow's milk fat, there are notable difference in the composition of sweet three ester aliphatic acid wherein and distribution and human milk fat.C16:0 accounts for 45% of its total amount in the Sn-2 position in the cow's milk fat, is lower than 70% in the human milk fat; Unsaturated fatty acid content in the cow's milk fat is starkly lower than human milk fat.
(2) directly be in harmonious proportion with vegetable oil.
Directly be in harmonious proportion with vegetable oil, aliphatic acid is formed and can be met the requirements well, but different with human milk fat on sweet three ester structures.
(3) carry out ester exchange at random with miscella.
Carry out ester exchange at random with miscella, it is similar that aliphatic acid is formed, and can accomplish that also the composition of Sn-2 position is similar, but structure is Sn-1 in this product, and the content of 3 unrighted acid Sn-2 saturated fatty acids (OPO or OPL) is less.
(4) to be rich in the grease of palmitic acid on the enzyme process ester exchange acquisition Sn-2 position.
Can produce the product that structure comparatively meets with this kind method, but complex process, production cost is very high.
Occurring in nature, sweet three ester structures of lard are very near human milk fat, be rich in Sn-1, sweet three esters of 3 unrighted acid Sn-2 saturated fatty acids (mainly being palmitic acid) structure, wherein about 67% palmitic acid is distributed on the Sn-2 position, be a kind of very desirable human milk fat substituted raw material, but the stearic acid content of lard is too high, influences its fusing point and baby's absorption; Middle carbon chain fatty acid content is low excessively, is unfavorable for replenishing fast of energy; The ratio of essential fatty acid n-6PUFAs and n-3PUFAs is higher.Therefore, lard must could utilize through modification.The method report that a large amount of use chemical modifications and bio-modification are arranged both at home and abroad, but all not too economy and safety.
