Embodiment 1

[0043] Embodiment one: the preparation of high OPO (containing OPL) fractionation lard

[0044] Raw lard: iodine value (IV): 66.4

[0045] Melting point: 33.1°C; OPO (including OPL)%: 39.8 The fractionation process is as follows:

[0046] Heat the raw lard to 50-60°C, stabilize it for 20 minutes, then cool down to 25°C at a rate of 4-6°C / hour, then cool down to 19-17°C at a rate of 1.5-2.5°C / hour, and crystallize at constant temperature After 5-10 hours, stir all the above-mentioned processes, and finally return to the temperature of 0-1°C, and start to separate after stabilization. The initial filtration pressure is 6bar, and stop after pressurizing to 12bar. The liquid target product with OPO (including OPL) content of 85.3% - fractionated lard was obtained, with a yield of 49.7%.

Embodiment 2

[0047] Example 2: Preparation of breast milk fat substitute oil

[0048] The fractionated lard obtained in Example 1 was mixed with several other oil raw materials according to the ratio shown in Table 5 to make 1 kg of blended oil, which was then subjected to a refining process, wherein the refining deodorization temperature was 235° C. and the residence time was 50 minutes to produce a The fatty acid composition and triglyceride structure are similar to breast milk fat and the breast milk fat substitute oil whose trans acid content is less than 1%, its fatty acid composition is shown in Table 6.

[0049] Grease type

[0050] table 5

[0051] In Table 5, palm oil and milk fat are "other animal and vegetable oils" in the raw material formula.

[0052] Mixed oil (%)

Embodiment 3

[0055] The result of Example 1 is mixed with lard and soybean oil, palm oil (iodine value is 50.5), coconut oil, and deep-sea fish oil in the ratio shown in Table 7 to make 1kg blended oil, and then through the refining process, wherein in the deodorization stage According to the conditions of temperature 235°C, residence time 50 minutes, and vacuum degree 2.3mbar, breast milk fat substitute oil was obtained, and its key indicators are shown in Table 8.

[0056] Grease type

Abstract

The invention provides a method for preparing breast milk fat which replaces oil and fat. The method comprises the steps of: mixing oil and fat with the C16:0 content being higher than 20% and the esterifying rate of C16:0 in a Sn-2 position being higher than 70% as the main raw materials, oil and fat with an intermediate carbon chain fatty acid (C8:0, C10:0 and C12:0) content being higher than 50%, oil and fat with the n-3 unsaturated fatty acid content being higher than 5% and / or the n-6 unsaturated fatty acid content being higher than 20% and other animal and vegetable oils at a certain proportion, and refining. The fatty acid composition and the triglyceride structure of the prepared oil and fat for replacing the breast milk fat are similar to those of the breast milk fat. The content of the trans-fatty-acid is lower than 1.0%. The prepared oil and fat has mild taste; and is suitable for the preparation of the infant formulation food.

Description

technical field [0001] The invention relates to a production method of breast milk fat substitute oil. Background technique [0002] Breast milk is the best food that human beings provide to infants (especially newborns). It provides various physiologically active characteristics and comprehensive and sufficient nutrition required by infants, and also provides essential fatty acids that are necessary for infants but cannot be synthesized in the body. etc., to ensure that babies can grow up healthy and free from many diseases within six months of birth (references: 1. Zheng Jianxian. Functional Food [M] Volume III, Beijing: China Light Industry Press. 1999; 2 . Wu Kegang, Yang Liansheng, Song Xianghua. Polyunsaturated fatty acids in breast milk [J]. China Dairy Industry. 2000). Breast milk contains 3%-5% lipids, and more than 98% of the lipids are triglycerides, which are one of the main nutrients in breast milk and provide 45% of the energy required by infants (0-6 months ...
