Description

Diglyceride oil powder for weight management and preparation method thereof Technical Field The invention relates to the technical field of weight management, in particular to diglyceride oil powder for weight management and a preparation method thereof. Background Traditional weight management means mainly depend on diet control, exercise intervention and drug therapy, but have the remarkable limitations that diet and exercise scheme compliance is low, long-term effects are difficult to maintain, the drug intervention can inhibit fat absorption but accompanies gastrointestinal side effects, and rebound is easy after drug withdrawal, and the surgical operation can quickly reduce weight, but has high risk of wound and high cost. In recent years, functional foods are becoming research hotspots due to their natural and safe properties, but their development still faces a core problem, namely how to realize sustainable fat reduction through precise metabolic regulation, rather than relying on heat limitation alone. The existing meal replacement products mostly adopt high dietary fiber or protein for compounding, but can increase satiety in a short period, but lack of targeted regulation on key fat metabolism channels, so that the body fat rate is reduced to a limited extent, and metabolic indexes such as insulin sensitivity and the like cannot be improved. In view of the above-described related art, the inventors found that the current studies of weight management functional components mainly focused on three major directions, fat metabolism regulation, inhibition of carbohydrate absorption, and promotion of energy consumption. Although these components show potential in vitro experiments, their practical utility is greatly compromised by technical limitations. The existing compounding scheme mostly adopts simple physical mixing and lacks a synergistic design among components. Most products are directed to only a single metabolic pathway, lacking systematic intervention on the "intake-absorption-storage-consumption" full link, resulting in a slow decrease in body fat rate. And secondly, the stability and the delivery efficiency of the weight management functional ingredient are insufficient. The high temperature processing results in heat sensitive component activity loss rate over 40%, poor compatibility of fat soluble component and water phase medium, easy delamination after cold water brewing, and practical absorption rate lower than 50%. Disclosure of Invention In order to overcome the defects of single metabolic regulation and control of the existing weight management functional components and insufficient component stability and delivery efficiency, the application provides diglyceride oil powder for weight management and a preparation method thereof. In a first aspect, the present application provides a diglyceride oil powder for weight management, which adopts the following technical scheme: A diglyceride oil powder for weight management comprises, by weight, 18-30 parts of flaxseed diglyceride, 10-20 parts of konjak extract, 3-8 parts of L-carnitine, 3-8 parts of white kidney bean extract and 2-5 parts of green coffee extract, wherein the flaxseed diglyceride is a flaxseed diglyceride with a sn-1 and 3 structure ratio of not less than 85%. Through the technical scheme, the multi-target weight regulation network is constructed by taking the flaxseed diglyceride as a core and combining the konjak extract, the L-carnitine, the white kidney bean extract and the green coffee extract. The flaxseed diglyceride preferentially enters a mitochondrial beta-oxidation path rather than a fat storage path through activating a PPARalpha receptor, the konjak extract enhances satiety through prolonging gastric emptying time, the L-carnitine and the flaxseed diglyceride cooperate to promote fatty acid transport across a mitochondrial membrane, the speed limiting bottleneck of carnitine palmitoyl transferase is solved, the white kidney bean extract inhibits carbon water from being converted into glucose, the green coffee extract activates an AMPK (open-end-of-line) path to promote fat decomposition, and a synergistic effect of fat-carbohydrate double blocking and energy consumption is formed. The combination breaks through the action limitation of single components by regulating and controlling the full links of ingestion, absorption and metabolism. Further, the flaxseed diglyceride with the sn-1,3 structure ratio of more than or equal to 85% is prepared by adopting the following technical scheme: taking flaxseed diglyceride, placing at 150-160deg.C and 3-5MPa, and distilling for 25-30min; and (3) taking distillate, and carrying out secondary distillation treatment for 25-30min at 200-220 ℃ and under the pressure of 1-3MPa to obtain the flaxseed diglyceride with the sn-1 and 3 structure ratio of more than or equal to 85%. Through the technical scheme, the sn-1,3 structure is accurately enriched through a two-stage molecul
