[0015] Antioxidant Composition Formulation and Treatment Process

[0016] The composition formula for preventing anthocyanin oxidation is: 5-20 parts by weight of disodium edetate and 4-6 parts by weight of sodium bisulfite. The optimal preparation ratio is 10 parts by weight of disodium edetate and 5 parts by weight of sodium bisulfite. Protect and seal with carbon dioxide during extraction and storage. The specific treatment process is: take a 50% ethanol solution by volume, add disodium edetate and sodium bisulfite as a solution for roselle extraction, that is, an ethanol mixture, in which sodium bisulfite and disodium edetate The concentrations are 0.05mg / mL and 0.1mg / mL respectively; take an appropriate amount of roselle medicinal materials, cut them into pieces, add 6-10 times the weight of the above ethanol mixture, and fill the container with CO 2 Protect and seal with a ground plug, ultrasonically extract 3 times at 50°C, each time for 15-30min, filter, combine the ...

Abstract

The invention discloses a treatment process for preventing anthocyanin oxidation during the extraction and preservation of roselle anthocyanins. The treatment process comprises the following steps: taking an ethanol solution with the volume fraction of 50%, adding disodium edetate dihydrate and sodium hydrogen sulfite as a solution for roselle extraction, namely, an ethanol mixed solution, takinga roselle medicinal material, cutting into pieces, adding the ethanol mixed solution with the weight being 6-10 times the weight of the roselle medicinal material pieces, filling the container with CO2 for protection, sealing with a grinding plug, ultrasonically extracting 3 times at 50 DEG C with 15 to 30 minutes each time, filtering, combining filtrate, performing rotary evaporation and concentration at 50 DEG C, freeze-drying the concentrated liquid by a freeze-drying process, filling the freeze-dried powder with CO2 for protection, and sealing. According to the treatment process, a drug formula is selected carefully, the extraction process and the preservation method are optimized, and the oxidation degeneration and failure of anthocyanins can be effectively prevented in extraction andpreservation processes.

Description

technical field [0001] The invention belongs to the technical field of anti-oxidation treatment process for traditional Chinese medicine and food, and in particular relates to a treatment process for preventing oxidation of anthocyanin during extraction and storage of roselle anthocyanin. Background technique [0002] Roselle ( Hibiscus Sabdariffa L., Roselle) is an annual herb of the Malvaceae family, also known as Roselle, native to West Africa, India and Central America. Roselle, sour in taste, cold in nature, traditional Chinese medicine believes that it can calm the liver and reduce fire, eliminate fatigue, refresh the brain and calm the nerves, and help digestion. "Three highs" (high blood sugar, high blood pressure and high blood fat) have good health care and therapeutic effects. [0003] The main medicinal ingredients of roselle are anthocyanins. Anthocyanins are a kind of excellent antioxidants, which can scavenge free radicals, help regenerate vitamin C and del...
