preparation example Construction

[0071] In one embodiment, the present invention provides the preparation method of above-mentioned grease composition, described method comprises the steps:

[0072] (i) Alcoholysis of triglycerides containing palmitic acid with alcohols having 1-6 carbon atoms to obtain oil A containing 2-monoglyceride palmitate, wherein, based on the glycerol containing palmitic acid The triglyceride comprises at least 40 mol%, preferably at least 45 mol%, more preferably at least 50 mol% palmitic acid residues, based on all acyl groups in the triester;

[0073](ii) Preparation of fat mixture B containing oleic acid or its non-glycerides and linoleic acid or its non-glycerides from oleic acid or its non-glycerides and linoleic acid or its non-glycerides; Prepare the fat mixture B containing oleic acid or its non-glycerides and linoleic acid or its non-glycerides from fats and oils of non-glycerides and linoleic acid or its non-glycerides;

[0074] Wherein, relative to the total weight of th...

Embodiment 1

[0118] Example 1: The target fat composition prepared by fat mixture B with different ratios of free oleic acid and its residues to free linoleic acid and its residues

[0119] At 52° C., 100 g of palm stearin shown in Table 3 below (based on the total acyl groups in palm stearin, the palm stearin contains 61 mol% of palmitic acid) was dissolved in 100 ml of acetone, and then Add 50ml absolute ethanol and stir. Next, at 52° C., 2 wt % Lipozyme RM IM (2 g) enzyme preparation (Novozymes) of palm stearin was added to react for 48 hours. Subsequently, the reaction was terminated by removing lipase, and excess acetone and ethanol were removed from the obtained product by vacuum distillation at 45° C.; the residue was collected to obtain fat A containing 2-monoglyceride palmitate.

Embodiment 2

[0129] Example 2: Prepare the target oil composition by mixing different proportions of oil A and fat mixture B

[0130] At 52° C., 200 g of palm stearin as shown in Table 3 above (wherein, based on the total acyl groups in palm stearin, the palm stearin contains 61 mol% of palmitic acid) was dissolved in 200 ml of acetone, and then 100 ml of absolute ethanol was added thereto and stirred. Next, at 52° C., 2 wt % Lipozyme RM IM (4 g) enzyme preparation (Novozymes) of palm stearin was added to react for 48 hours. Subsequently, the reaction was terminated by removing lipase, and excess acetone and ethanol were removed from the obtained product by vacuum distillation at 45° C.; the residue was collected to obtain fat A containing 2-monoglyceride palmitate.

[0131] Fat mixture B was obtained by mixing oleic acid (800 g) with linoleic acid (800 g). Weigh grease A (100g), add 100g, 200g, 300g, 400g, 500g of fat mixture B respectively, that is, the mass ratio of grease A to fat mi...

Abstract

The present invention discloses a grease composition comprising 1-oleoyl-2-palmitoyl-3-linoleoyl-rac-glycerol (OPL) and 1,3-dioleoyl-2-palmitoyl glycerol (OPO) and a preparation method of the grease composition. The amount of OPL is 25wt% or more of that of the grease composition, and the total amount of OPL and OPO accounts for 40wt% or more of that of the grease composition. The preparation method of the grease composition comprises the following steps: carrying out alcoholysis on triglyceride containing palmitic acid to obtain grease A containing 2-monoglyceride palmitate; and carrying outsn-1,3 directional transesterification on the grease A and a fat mixture B containing oleic acid or non-glyceride of oleic acid and linoleic acid or non-glyceride of linoleic acid. The grease composition disclosed by the invention better conforms to the main composition of breast milk fat of Chinese people, and can be widely applied to infant formula milk powder as an additive.

Description

technical field [0001] The invention belongs to the field of food additive processing, and in particular relates to a fat composition and a preparation method thereof whose composition and content are closer to Chinese lactate. Background technique [0002] Breast milk is the most important source of energy for infants and young children in the early stages of growth. The composition of fat and fatty acids in breast milk can meet the needs of infants and young children for their rapid growth. Breast milk contains about 3-4.5% fat, 98% of which are triglycerides, which provide 50-60% of the energy for infants and young children, and play a key role in the absorption of various vitamins and minerals for infants and young children effect. However, due to the influence of various factors, more and more families in my country rely on formula milk powder to feed infants and young children in recent years. In order to provide newborns with the healthiest, most suitable, human mil...
