preparation example Construction

[0064] In another aspect, the present invention provides the preparation method of above-mentioned grease composition, described method comprises the steps:

[0065] (i) provide palm stearin with an iodine value of 8-12;

[0066] (ii) in the presence of a catalyst for enzymatic transesterification, a fatty mixture of palm stearin with an iodine value of 8-12 and oleic acid or its non-glycerides and linoleic acid or its non-glycerides is subjected to Sn-1, 3 directional transesterification, so as to obtain the grease A through transesterification,

[0067] wherein said fat mixture is prepared from oleic acid or its non-glycerides and linoleic acid or its non-glycerides, or from fats and oils as sources of oleic acid or its non-glycerides and linoleic acid or its non-glycerides,

[0068] Wherein, relative to the total weight of the fat mixture, the total amount of free oleic acid and its residues and free linoleic acid and its residues accounts for more than 70 wt%, preferably ...

Embodiment 1

[0102] Example 1: Using fat mixtures with different ratios of oleic acid to linoleic acid to prepare the target oil composition

[0103] At room temperature, prepare the fat mixture according to the ratio shown in Table 3 below. After mixing, add 30ml of hydrochloric acid (2mol / L), heat in a water bath at 80°C for 50min, and hydrolyze to obtain fatty acid or non-glyceride ester of fatty acid. After the reaction, 100 ml of n-hexane was added to extract the hydrolyzate, the solvent was removed by a rotary evaporator, and dried to obtain four groups of fat mixtures. Wherein, the proportions of the total amount of free oleic acid and its residues and free linoleic acid and its residues to the total weight of the fat mixture are 65wt%, 70wt%, 75wt% and 80wt%, and free oleic acid and its residues The ratio to free linoleic acid and its residues is 1:1.

Embodiment 2

[0109] Embodiment 2: the fatty acid preparation target oil composition of the ratio of the total amount of free oleic acid and its residues and the total amount of free linoleic acid and its residues

[0110] At room temperature, the mixture was prepared according to the composition of the fat mixture shown in Table 5, and the mixture was hydrolyzed and extracted according to the method described in Example 1 to obtain four groups of fat mixtures. Wherein, the ratio of the total amount of free oleic acid and its residues to the total amount of free linoleic acid and its residues in the prepared fat mixture is 0.5:1, 1:1, 1.5:1, 2:1, 2.5 : 1 (in weight ratio), the total amount of free oleic acid and residues thereof and free linoleic acid and residues thereof accounts for 80wt% of the total weight of the fat mixture.

Abstract

The invention discloses a grease composition containing 1-oleic acid-2-palmitic acid-3-linoleic acid glyceride (OPL) and 1,3-dioleic acid-2-palmitic acid glyceride (OPO) and a preparation method thereof. In the grease composition, relative to a total weight of the grease composition, the OPL accounts for 20 wt% or more, and a total quantity of the OPL and OPO accounts for 40 wt% or more. The preparation method for the grease composition comprises the following steps: enabling palm stearin of which an iodine value (IV) is 8-12 to perform Sn-1,3 directional ester exchange with a fat mixture containing oleic acid or non-glyceride thereof and linoleic acid or non-glyceride thereof. The grease composition is more in comply with major components of Chinese people breast milk, and can be extensively applied to infant formula milk as an additive.

Description

technical field [0001] The invention belongs to the field of food additive processing, in particular, the invention relates to a fat composition and a preparation method thereof which are closer to the composition of Chinese breastmilk fat. Background technique [0002] Breast milk is the best food for newborns and the main source of nutrition for infants to grow. Breast milk contains about 3% to 5% fat, which can provide 50% to 60% energy for infants and young children. Triglycerides in breast milk fat account for more than 98%, and triglycerides in breast milk fat have a special molecular structure, which is specifically manifested in the following: unsaturated fatty acids have the highest fatty acid content, of which oleic acid and linoleic acid are the most Mainly (as high as 70%-80%), and these unsaturated fatty acid residues are mainly distributed in the sn-1,3 positions of triglycerides; saturated fatty acid residues account for 20%-30%, mainly palmitic acid, And mo...
