Description

Technical Field

[0001] The invention belongs to the field of food technology, and particularly relates to a medium-chain triglyceride composition and a sugar-free embedding preparation method and application thereof. Background Art

[0002] Obesity is mainly caused by excessive energy intake, which promotes excessive synthesis of body fat and leads to excessive accumulation of body fat. After fat is formed in the body, it will accumulate in the interstitial matrix of mature fat cells, causing fat volume to increase, and body weight, body fat content, blood lipids, etc. In addition to reducing energy intake or increasing incremental consumption, promoting the level of fat metabolism can improve obesity and achieve the goal of weight loss. Fat metabolism is the process of digestion, absorption, synthesis and decomposition of fat in the body under the action of enzymes. Fat metabolism can ensure the normal operation of physiological functions.

[0003] Chinese invention patent CN114515009A discloses a composition with weight loss and lipid-lowering effects and its application. The composition with weight loss and lipid-lowering effects includes components: Acanthopanax senticosus extract, litchi kernel extract, brewer's yeast and nuciferine. The four components cooperate with each other and synergistically enhance the effect, which significantly promotes human fat metabolism and balances it, thereby achieving the effects of lowering blood lipids and reversing fatty liver. At the same time, it has significant effects on weight loss, laxative, detoxification and sleep promotion.

[0004] Chinese invention patent CN116530683A discloses a food composition for enhancing fat metabolism and a preparation method thereof. The raw materials of the food composition include medium-chain triglyceride microcapsule powder, green coffee powder, green tea powder, seaweed powder, sea buckthorn powder, wolfberry powder, stachyose, prickly pear cactus, virgin coconut oil microcapsule powder and sugarcane polyphenols; the final composition can enhance fat metabolism.

[0005] Medium-chain triglycerides (MCT) are one of the sources of dietary fat and can be used as a raw material or food additive for weight loss functional foods. At present, single-ingredient foods have a weak overall ability to improve fat metabolism, while compound foods have problems such as complex formulation and preparation processes, poor universality, weak functionality, and poor efficacy. Plant active ingredients that have the effects of weight loss and promoting fat metabolism are easily oxidized and even have weakened active functions during storage, resulting in reduced weight loss effects such as fat metabolism. Therefore, it is necessary to provide an encapsulation technology to encapsulate medium-chain triglycerides and plant active ingredients to improve the stability of the composition and further synergistically improve the effects of weight loss and fat metabolism.

[0006] Chinese invention patent CN111150086A discloses an embedding wall material and an embedding process and application of microcapsule tartary buckwheat flavonoids, wherein the embedding wall material includes: resistant dextrin and dextrin wall material, wherein the dextrin wall material includes maltodextrin and cyclodextrin; the embedding process of microcapsule tartary buckwheat flavonoids is as follows: after tartary buckwheat bran is crushed, ethanol is subjected to segmented ultrasonic extraction to obtain an extract, the extract is concentrated to obtain a concentrated solution containing flavonoids, the concentrated solution is added to the embedding wall material liquid, mixed and spray-dried to obtain microcapsule tartary buckwheat flavonoids. The embedding wall material has good embedding effect, high embedding rate, high drug loading, and can better maintain the physiological activity of tartary buckwheat flavonoids.

[0007] Dextrin wall materials are often used to encapsulate active substances and aroma substances. However, when cyclodextrin or maltodextrin is used as the wall material for preparing products, the physical and chemical properties of the product, such as solubility, hygroscopicity, and stability, are often affected by the type, ratio, and glucose equivalent (DE) of dextrin, which in turn limits the use of cyclodextrin or maltodextrin.

[0008] In view of this, it is necessary to seek a composition with weight loss and metabolism enhancement functions, select a suitable embedding material to maintain the activity of the medium chain triglyceride and plant active ingredient composition, and further improve the stability and weight loss effect of the product.

[0085] It can be seen from Table 2 that the properties of the medium chain triglyceride composition of the present invention are still stable under accelerated storage conditions. The embedding method of the present invention improves the embedding rate and the stability of the medium chain triglyceride composition.

[0086] Experiment 2: Metabolism and weight loss effect experiment

[0087] SPF grade KM male mice, weighing about 20g (initial weight), were fed ad libitum and adaptively fed for 1 week. They were randomly divided into a normal group, a model group, an embodiment 1-5 group, a comparative example 1-3 group, and a comparative example 5 group, with 6 mice in each group. Except for the normal group, the other groups were fed a high-fat diet every day, and the normal group was fed a normal diet every day. The feeding was continued for 8 weeks to create a hyperlipidemia and obesity model.

[0088] Subsequently, the Example 1-5 group, the Comparative Example 1-3 group, and the Comparative Example 5 group were fed with the corresponding medium-chain triglyceride composition at 0.8 g / kg / day, and the normal group and the model group were fed with the same amount of physiological saline. After continuous gavage for 2 weeks, except for the normal group, the mice in other groups were intraperitoneally injected with hypoxanthine (600 mg / kg) to create a hyperuric acid model. One hour later, the mice in each group were injected with 3% chloral hydrate. The body weight (final body weight) was recorded.

[0089] Then the eyeballs were removed and blood was collected to measure the total cholesterol (TC), triglyceride (TG) and uric acid levels in serum.

[0090] Determination of total cholesterol (TC) and triglyceride (TG) content in serum: After blood collection, let it stand at room temperature for 1 hour, centrifuge, take serum, and determine TC and TG content according to the operating instructions of the kit. The uric acid content in serum was determined using a veterinary automatic biochemical analyzer (BS-240VET, Shenzhen Mindray).

[0091] The body weight changes of mice in each group are shown in Table 3.

[0092] The levels of TC, TG and uric acid in serum are shown in Table 4.

[0093] Table 3

[0094]

[0095] As can be seen from Table 3, the body weight of the mice in the model group increased significantly, and the hyperlipidemia and obesity model was successfully established. The body weight of the mice in the normal group gradually increased due to natural growth; the body weight of the mice fed with the medium-chain triglyceride composition of the present invention was effectively controlled, and the weight loss effect was significant.

[0096] Table 4

[0097]

[0098] In Table 4, compared with the model group, # P<0.05, ## P<0.01; Compared with Example 1, the comparative group & P<0.05, && P<0.01.

[0099] From the results in Table 4, it can be seen that the medium-chain triglyceride composition of the present invention can reduce blood lipid and uric acid levels and significantly improve the metabolic function of hyperlipidemia model mice. Therefore, the medium-chain triglyceride composition of the present invention has a significant effect of improving metabolism and inhibiting obesity.

[0100] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions of the technical solution of the present invention by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the present invention.
