Abstract

The invention belongs to the technical field of food processing, and particularly relates to a shaddock high-activity oral liquid with stability, oxidation resistance and lipid-lowering property, and a preparation method and application thereof. The oral liquid takes shaddock dietary fiber as a core active ingredient, is matched with limonin, and solves the technical problems that the dietary fiber is easy to aggregate and the limonin is difficult to dissolve in water by combining the ultrasonic dispersion-high-speed shearing emulsification-composite homogenization technology through the compound emulsification of sucrose fatty acid ester and mono-diglycerol fatty acid ester. The preparation process comprises preparing water phase containing dietary fiber and related adjuvants and oil phase containing limonin, emulsifying, ultrasonic homogenizing, and sterilizing to obtain the final product. The invention has the beneficial effects that the oral liquid has the functions of resisting oxidization and reducing blood fat, realizes the high-value utilization of low-value resources of pomelos, and is suitable for the development of functional foods.

Description

Pomelo high-activity oral liquid with stability, oxidation resistance and lipid-lowering property and preparation method and application thereof Technical Field The invention belongs to the technical field of food processing, and particularly relates to a shaddock high-activity oral liquid with stability, oxidation resistance and lipid-lowering property, and a preparation method and application thereof. Background The pomelo fruits are widely planted special fruits in China, are rich in various natural active ingredients such as dietary fibers, limonin, flavonoids, polyphenols and the like, have good antioxidant activity, have excellent physiological functions of adsorbing cholesterol, combining cholate, regulating blood fat and the like, and have wide application prospects in the fields of antioxidant and lipid-lowering functional foods. However, a large amount of inferior fruits, pericarps and processing byproducts generated in the processing process of pomelos are often abandoned due to low utilization rate, so that not only is the resource wasted, but also environmental pressure is brought. At present, there are several oral liquid or emulsion technologies involving citrus resources or active ingredients. For example, the chinese patent application publication No. CN118120906a discloses a citrus ferment oral liquid, which mainly uses ferment stock solution and inulin, and focuses on relaxing bowel, and has simple process (filtration, blending, homogenization), but involves no deep stabilization treatment of insoluble components. The Chinese patent application with publication number CN111972662A discloses an oral liquid containing astaxanthin, which adopts algae microcapsule powder to solve the problems of water dispersibility and stability of astaxanthin, relies on gellan gum and the like to construct a colloid suspension system, and the process focuses on classifying, shearing and dispersing different materials. Based on the existing public data retrieval, no oral liquid product with stability, oxidation resistance and lipid-lowering property is realized by taking the shaddock dietary fiber as a core active ingredient and combining a specific emulsification process. In addition, the existing oral liquid products have the problems of poor physical stability and to-be-improved sensory quality, and lack of targeted products which take natural plant components as cores and simultaneously have the functions of resisting oxidation and regulating blood fat and improving the functional stability in the digestion process. Disclosure of Invention The invention aims to overcome the defects of the prior art and provide the high-activity oral liquid of the pomelo, which has high stability and good sensory quality, and fully plays the roles of synergistic antioxidation and auxiliary lipid-lowering of the dietary fiber of the pomelo and limonin, and the preparation method and the application thereof. In order to solve the technical problems, the invention adopts the technical scheme that the high-activity pomelo oral liquid with stability, oxidation resistance and lipid-lowering property is provided, and is prepared by emulsifying and homogenizing a water phase containing pomelo dietary fibers and an oil phase containing limonin; The emulsifying and homogenizing comprises sequentially performing the following steps of adding the oil phase into the water phase under high-speed shearing to perform primary emulsification, performing ultrasonic treatment on the obtained system, and performing high-speed homogenizing treatment; Wherein the water phase contains a water phase emulsifier sucrose fatty acid ester, and the oil phase contains an oil phase emulsifier mono-and diglyceride fatty acid esters. Further, in the high-activity oral liquid of the pomelo with stability, oxidation resistance and lipid lowering property, the content of the dietary fiber of the pomelo in the oral liquid is 8-12 mg/mL, the mass volume percentage of limonin in the oral liquid is 0.008% -0.012%, and the dietary fiber of the pomelo is prepared by homogenizing and ultrasonic treatment. As is clear from the above description, in the above-mentioned proportion, the content below the lower limit may cause the function to be insignificant or the flavor to be light, and above the upper limit may cause the system to be too thick, the taste to be bitter or the stability to be reduced. This definition ensures an optimal balance of product functionality and acceptability. Further, in the shaddock high-activity oral liquid with stability, oxidation resistance and lipid-lowering property, the mass and volume percentage of the sucrose fatty acid ester in the oral liquid is 1.8-2.6%, and the content of the mono-and diglyceride fatty acid esters in the oral liquid is 1.6-2.4%. From the above description, the above ratio of sucrose fatty acid ester (with strong hydrophilicity) to mono-or diglyceride fatty acid ester (with strong lipophilicity) can effectively
