preparation example Construction

[0076] The grease composition obtained by the preparation method of the present invention satisfies the following characteristics:

[0077] (1) by weight, sn-2 palmitic acid accounts for more than 55% of the total content of palmitic acid;

[0078] (2) relative to the total weight of the oil composition, the total amount of OPL and OPO accounts for more than 40wt%; wherein, relative to the total weight of the oil composition, OPL accounts for more than 25wt%; and

[0079] (3) Relative to the total weight of the oil composition, the content of tripalmitin triglyceride (PPP) is less than 10wt%.

[0080] Compared with the existing human milk substitute fat, the triglyceride component and content of the oil composition of the present invention are closer to the triglyceride component in Chinese breast milk fat, and can be used as a human milk substitute fat in food for infants and young children. Foods for infants and young children include but are not limited to infant formula m...

preparation example 1

[0083] Preparation Example 1: Preparation of Grease A

[0084] Weigh 100g of palm stearin with an iodine value of 36 obtained by dry fractionation, place it in a 250ml reactor, and preheat it at 55°C; after the temperature stabilizes, weigh 10g of Lipozyme TL IM enzyme preparation and add it to In the reactor, react under stirring for 8 hours to obtain grease A. During the reaction, samples were taken every hour from the third hour, and the weight ratio of palmitic acid at the sn-2 position to the total palmitic acid was determined by using the inspection method of A.2 in GB30604-2015. The results are shown in Table 3 middle. table 3

[0085]

[0086] It can be seen from the above table that after random transesterification, the content of sn-2 palmitic acid in triglycerides accounts for a significant increase in the total content of palmitic acid. After reacting for 8 hours, the weight ratio of sn-2 palmitic acid in the fat A obtained by random transesterification to th...

preparation example 2

[0087] Preparation Example 2: Preparation of Grease A

[0088] Weigh 100g of palm stearin with an iodine value of 18 obtained by dry fractionation, place it in a 250ml reactor, and preheat it at 60°C; after the temperature stabilizes, weigh 10g of Lipozyme TL IM enzyme preparation and add it to In the reactor, react under stirring for 8 hours to obtain grease A. During the reaction, samples were taken every hour from the third hour, and the weight ratio of palmitic acid at the sn-2 position to the total palmitic acid was determined by using the inspection method of A.2 in GB30604-2015. The results are shown in Table 4 middle.

[0089] Table 4

[0090]

[0091] It can be seen from the above table that after 4 hours of reaction, the weight ratio of the sn-2 palmitic acid content of oil A obtained through random transesterification to the total palmitic acid content is close to 33.3%, indicating that the random transesterification is relatively complete.

Abstract

The invention provides a grease composition. The grease composition contains 1-oleic acid-2-palmitic acid-3-linoleic acid glyceride (OPL) and 1,3-dioleic acid-2-palmitic acid glyceride (OPO), and ingredients and content of the grease composition are more approximate to a Chinese people breast milk grease structure. The invention further provides a preparation method for the grease composition. Themethod comprises the following steps: using palm stearin of which an iodine value is 18 to 36 as a raw material, and acquiring grease A through random ester exchange; and enabling the grease A 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, separating and purifying, thereby acquiring the grease composition.

Description

technical field [0001] The invention belongs to the field of food additive processing, and specifically relates to an oil composition and a preparation method thereof whose composition and content are closer to that of Chinese lactate. The oil composition contains 1-oleic acid-2-palmitic acid-3 -Linoleic acid triglyceride (hereinafter referred to as OPL) and 1,3-dioleic acid-2-palmitic acid triglyceride (hereinafter referred to as OPO). Background technique [0002] Breast milk is the most important source of energy for infants in the early stages of growth, and 50%-60% of the energy supply comes from triglycerides in breast milk. Therefore, triglycerides play a vital role in the healthy growth of infants and young children. 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 infants and young children with the healthiest, most suitable, an...
