5 results about "Phloretin" patented technology

This invention relates to the field of food preservation technology and discloses a liquid preservative for preserving fresh walnut kernels. The preservative comprises a natural preservative, a solubilizing and stabilizing agent, and a solvent. This liquid preservative uses natural phloretin as the preservative component, combined with Tween 80 as a solubilizing and stabilizing agent and ethanol as a solvent. This effectively solves the problems of poor water and oil solubility and inadequate stability of phloretin, allowing it to be stably dispersed in the preservative system and fully exert its antioxidant and antimicrobial effects. Furthermore, the preparation method is simple and easy to implement, and the production process is safe and controllable. It is convenient to use; the preservation of fresh walnut kernels can be achieved through dilution and soaking. The diluted solution can be reused, reducing usage costs. Simultaneously, it can inhibit bacterial growth during the storage of fresh walnut kernels, delay oxidative deterioration, maintain their good appearance and quality, extend shelf life, and meet the market demand for high-quality fresh walnut kernels.

This invention belongs to the field of pharmacology and provides the application of demethoxycurcumin and phlorizin in the preparation of drugs that inhibit β-lactoglobulin glycosylation. The synergistic inhibitory effects and mechanisms of demethoxycurcumin and phlorizin on AGEs were systematically investigated. Fluorescence spectroscopy and carbonyl / thiol / amino group assays confirmed that demethoxycurcumin and phlorizin can synergistically inhibit β-lactoglobulin glycosylation at appropriate concentrations. Circular dichroism spectroscopy and other experiments showed that the combined use of the two can better alleviate protein secondary structure changes and aggregation. They competitively bind to the same glycosylation site, synergistically resist oxidation, thereby inhibiting AGEs formation, and synergistically reducing oxidative stress, cell damage, and apoptosis at the cellular level. Therefore, the combined application of these two drugs has potential therapeutic value in intervening in diabetic complications.

The application discloses a method for simultaneously determining contents of advantame, phloretin and perillartine in edible essence based on UPLC, and belongs to the technical field of chemical analysis and detection, and comprises preparation of three sweetener series standard solutions, preparation of a to-be-measured sample solution, and subsequent detection and quantitative analysis by means of an ultra-high performance liquid chromatograph, and is suitable for simultaneous detection of the three sweeteners advantame, phloretin and perillartine. Compared with the prior art, different detection methods need to be adopted for detection of the three sweeteners, and the method can effectively separate and quantitatively analyze the three sweeteners with different absorption wavelengths at one time, and is rapid and convenient to operate, high in detection efficiency and easy to popularize.

The invention relates to a combination containing an extract of Coleus forskohlii, an apple extract rich in proanthocyanidins, an extract of grape pomace and a phloretin powder.
