The invention specifically relates to a method for estimating in-vitro detoxification effect of a mycotoxin detoxification agent by using liquid chromatography, belonging to the technical field of biological detection. The method comprises the following steps: (1) early stage preparation: I, drafting of a standard curve of mycotoxin; II, preparation of a sample of the detoxification agent; and III, acquisition of a reaction medium; (2) detoxification: I, evaluation of in-vitro adsorption detoxification; and II, evaluation of simulated in-vivo adsorption detoxification; and (3) liquid chromatographic detection. The method for estimating in-vitro detoxification effect of the mycotoxin detoxification agent by using liquid chromatography can simulate gastrointestinal environments, adopts supernatant of chyme in the alimentary canal of an animal as a reaction medium, completely reproduce the gastrointestinal environment in the animal and more authentically evaluate the adsorption effect of an adsorbent.

The invention provides an isodon amethystoides herbal tea drink and a preparation method thereof. The herbal tea drink is characterized by being prepared from the following traditional Chinese medicine materials in parts by weight: 15 to 20 parts of isodon amethystoides, 5 to 15 parts of oldenlandia diffusa, 10 to 15 parts of sculellaria barbata, 3 to 10 parts of polygonum cuspidatum, 3 to 10 parts of honeysuckle, 7 to 11 parts of salvia miltiorrhiza, 10 to 15 parts of astragalus membranaceus, 3 to 10 parts of tea leaves, 7 to 11 parts of radix bupleuri and 2 to 5 parts of Chinese dates. Based on the innovation of medicine selection, a formula, proportions and the preparation method, the functions of the isodon amethystoides for clearing away heat and toxic materials, resisting bacteria and diminishing inflammation, cooling blood and scattering stasis, harmonizing stomach and protecting liver, relieving cough and asthma, regulating immunity and the like are fully exerted while the defect of gastrointestinal discomfort caused by taking the isodon amethystoides for a long time is overcome at the same time, so that the herbal tea drink has various functions for preventing and treating throat diseases, respiratory tract diseases, digestive tract diseases, gastrointestinal diseases and other diseases, low immunity and the like which are caused by haze and environmental pollution.

The invention provides a clopidol controlled-release microparticle preparation and a preparation method thereof. The clopidol controlled-release microparticle preparation has a core-shell structure, a mineral carrier which adsorbs clopidol forms a system inner core, and calcium alginate gel forms a system outer shell. The clopidol controlled-release microparticle preparation can effectively avoid burst release of drug in stomach, so that irritation to the stomach by the drug is reduced, and adverse reaction of a gastrointestinal tract is reduced. Granularity of the preparation is 50-900 micrometers, so that the preparation is convenient for being uniformly mixed with feed and conducive to livestock and poultry absorption, and bioavailability of the drug is improved. The preparation method is simple, and the preparation is free of dust pollution and suitable for industrialized production.

The invention provides a water-in-oil type high internal phase emulsion for carrying bitter substances and a preparation method thereof, and relates to the field of embedding and carrying of nutrient substances. The raw materials of the water-in-oil type high internal phase emulsion carrying the bitter substances comprise a water phase and an oil phase, and the water phase comprises the bitter substances and a solvent; the oil phase comprises liquid grease, solid grease and polyglycerol ricinoleate. A bitter substance solution formed by a bitter substance and a solvent is used as an internal water phase, and a lipid network structure constructed in a mode of combining liquid grease and solid grease is used as an external oil phase, so that a high-internal-phase emulsion with good stability is favorably formed, the encapsulation efficiency of the bitter substance and the content of the bitter substance in the emulsion are improved, and the bad flavor of the bitter substance is covered; the gastrointestinal tract digestion stability of bitter substances is improved.

The invention discloses application of LF/DHA-SPI/DHA micro-aggregate in foods for infants and crowds with gastrointestinal tract fragility. According to the application disclosed by the invention, the micro-aggregate having favorable DHA in vitro simulation digestion characteristics is constructed around a special-shaped aggregation effect, an effective construction way of the DHA micro-aggregate is explored, the DHA in vitro simulation digestion is improved, and a bran-new solution is provided for DHA steady state in application, so that a guiding effect is provided for the application of the LF/DHA-SPI/DHA micro-aggregate.
