Food-grade fluorescent nano-microemulsion and preparation method thereof

Abstract

The invention discloses a food-grade fluorescent nano-microemulsion and a preparation method thereof. The preparation method comprises the following steps: (1) mixing isoamyl acetate with ethanol, so as to obtain a mixed oil phase, adding polyoxyethylated castor oil, and stirring; and (2) dropwise adding water while stirring, so as to obtain uniform and transparent food-grade fluorescent nano-microemulsion. The oil-in-water food-grade fluorescent nano-microemulsion prepared by virtue of the preparation method has fluorescence characteristics, belongs to the field of food-grade nano-fluorescent materials, is toxic free and biodegradable and has good biocompatibility. The food-grade fluorescent nano-microemulsion does not need to be labeled when being used as a fluorescent nano-material, and no bracket is needed. The adopted raw materials are simple and easily available, isoamyl acetate is an aromatic additive for foods, the preparation cost of the product is low, and meanwhile, the food-grade fluorescent nano-microemulsion further has special fragrance. The high-temperature and high-pressure treatment is not required in the preparation method, and the preparation method is simple, feasible and high in process efficiency and meets the concepts of energy conservation and environment protection.

Description

technical field [0001] The invention relates to a method for preparing fluorescent nanometer microemulsion, which belongs to the field of production, preparation and application of microemulsion. Background technique [0002] For a long time, the research on functional factors in food and medicine has not been interrupted, and most of them focus on evaluating their physiological activities through cell and animal experiments, and the research on their mechanism of action is very difficult. The emergence and application of food-grade fluorescent probes can more intuitively detect some changes of functional factors in vivo and in vitro, so as to realize real-time monitoring of functional factors. [0003] Based on the extensive research on fluorescent materials, the research on fluorescent nanomaterials has set off a new wave. Phosphors are based on sensors that convert chemical, physical, biological, and other difficult-to-detect information into optical information for dete...
