Problems solved by technology

[0010] Although people are aware of the health benefits of OPO to infants, further improvement of intestinal function / or constipation in infants and young children needs to be strengthened, and how to promote the absorption and utilization of arachidonic acid has not yet been properly solved, so it is still It is necessary to optimize and improve the composition of oil and fat composition in formula food for infants and young children

Embodiment 1

[0029] The preparation of embodiment 1 grease composition

[0030] OPO triglyceride was purchased from Sigma Reagent Company; soybean oil, peanut oil, corn oil, palm oil, rapeseed oil, high oleic sunflower oil, coconut oil, pangasius oil and other oil raw materials were purchased from local supermarkets.

[0031] Experimental group 1: Tripalmitin was mixed with oleic acid and linoleic acid in a molar ratio of 1:7:7. In a solvent-free system, 10% NS40086 lipase of the total mass of the reaction substrate was added, and reacted at 60°C for 4 hours. After the reaction, free fatty acids are removed to obtain OPL triglycerides.

[0032] 0.35g soybean oil, 0.04g peanut oil, 0.05g corn oil, 0.02g palm oil, 0.05g rapeseed oil, 0.02g high oleic sunflower oil, 0.40g coconut oil, 1.60g pangasius oil, 0.90g OPL, 4.50 g of OPO was physically mixed to obtain oil composition experimental group 1.

[0033] Experimental group 2: Tripalmitin was mixed with oleic acid and linoleic acid in a mo...

Embodiment 2

[0050] This example studies the effects of feeding different feed oil compositions on the growth and calcium metabolism of young mice.

[0051] Feed 42 young mice with the dietary formula in Table 2, and after adaptive feeding for 1 week, they were randomly divided into 7 groups, 6 in each group, wherein the oil composition in the dietary formula of each group was the oil combination prepared in Example 1 respectively Experimental groups 1-4 and control groups 1-3. The litter and drinking water were changed every day. After one week, the young mice were fed individually in metabolic cages, and continued to be fed for another 2 weeks. The food intake and feces of the young mice in each group were recorded in the last 5 days. The feces were dried and weighed with feces samples, and then digested at high temperature in mixed acid (hydrochloric acid: nitric acid = 4:1) until clear and transparent, and the calcium content was measured by the arsine azo method.

[0052] Calcium abs...

Embodiment 3

[0061] This example studies the effect of feeding different feed oil compositions on young mice's feces firmness and frequency.

[0062] Feed 42 young mice with the dietary formula in Table 2, and after adaptive feeding for 1 week, they were randomly divided into 7 groups, 6 in each group, wherein the oil composition in the dietary formula of each group was the oil combination prepared in Example 1 respectively Experimental groups 1-4 and control groups 1-3. Change bedding and drinking water daily. After 1 week, the pups were placed in metabolic cages and fed separately for another 2 weeks, and the stool hardness and frequency of pups in each group were recorded within 2 weeks. Observing the softness and hardness and consistency of the feces of young rats compared with that of the common feed group obtained results (Table 4).

[0063] During the breeding process, the pups were generally in normal condition, with good mental state, smooth coat color and normal defecation

Abstract

The invention provides a fat composition. Triglyceride consists of C14-C18 fatty acids, the fat composition comprises 1-palmitoyl-2-oleoyl-3-linoleoyl-rac-glycerol (OPL), and 1,3-dioleoyl-2-palmitoylglycerol(OPO), wherein the total mass of OPL and OPO is 30-70%, and the mass ratio of the OPL to the OPO is (0.2 to 1) to (3 to 1). According to the fat composition provided by the invention, the triglyceride content and the concentration proportion are regulated, so that the constipation and defecation difficulty of babies can be helped, the running off of the nutrient components of the babies canbe reduced, the fat composition is used for promoting skeletal development of the babies, and absorption of tetraenoic acid (ARA) of peanuts can also be promoted.

Description

technical field [0001] The present invention relates to the field of food, and further relates to the field of oil. Background technique [0002] Human milk is the ideal food for newborn babies. The fat content in human milk is 3% to 5%, of which more than 98% is triglyceride. Human milk fat is the main nutrient for infants, which can provide about 50% of energy for infants. The triglycerides in human milk fat are mainly sn-USU (U refers to unsaturated fatty acids, S refers to saturated fatty acids), and about 70% of palmitic acid is distributed in the sn-2 position of triglycerides. [0003] Infant formula milk powder is a substitute for breast milk. Infant formula milk powder on the market is generally formulated with one or more of vegetable oil, cow milk or goat milk. The triglyceride composition of vegetable oil, cow milk or goat milk is higher than that of human milk. The difference, especially in vegetable oil-based formula foods, in which palmitic acid is mostly d...
