Embodiment 1

[0021] Take 7000L of bitter orange essence filtrate, and pass through a macroporous adsorption resin column with an inner diameter of one meter and a height of three meters at a flow rate of 4000L / h. After feeding, continue to wash with water until the color is light, and use 15% and 40% ethanol to elute successively, and collect 40% ethanol The eluent was recovered from ethanol to obtain a concentrated solution, and the concentrated solution was diluted to 10% of solid matter, passed through a macroporous adsorption resin column with an inner diameter of one meter and a height of three meters at a flow rate of 4000L / h, and was eluted successively with 15% and 40% ethanol, and collected 40 % ethanol eluent, reclaiming ethanol to obtain solids as a 63% concentrated solution, vacuum drying, to obtain 18kg dry cream powder.

[0022] After testing, the content of the rutin naringin in the obtained extract was 26.1%.

Embodiment 2

[0024] Take 7600L of bitter orange essence filtrate, pass through a macroporous adsorption resin column with an inner diameter of one meter and a height of three meters at a flow rate of 3800L / h. After feeding, continue to wash with water until the color is light, and use 15% and 40% ethanol to elute successively, and collect 40% ethanol The eluent was recovered from ethanol to obtain a concentrated solution, and the concentrated solution was diluted to 10% of solid matter, passed through a macroporous adsorption resin column with an inner diameter of one meter and a height of three meters at a flow rate of 4000L / h, and was eluted successively with 15% and 40% ethanol, and collected 40 % ethanol eluent, reclaiming ethanol to obtain solids as a 65% concentrated solution, vacuum drying, to obtain 18.6kg dry cream powder.

[0025] After testing, the content of naringin in the obtained extract rutin was 35.4%.

Embodiment 3

[0027] Take 7400L of bitter orange essence filtrate, pass through a macroporous adsorption resin column with an inner diameter of one meter and a height of three meters at a flow rate of 4500L / h. After feeding, continue to wash with water until the color is light, and use 15% and 40% ethanol to elute successively, and collect 40% ethanol The eluent was recovered from ethanol to obtain a concentrated solution, and the concentrated solution was diluted to 10% of solid matter, passed through a macroporous adsorption resin column with an inner diameter of one meter and a height of three meters at a flow rate of 4000L / h, and was eluted successively with 15% and 40% ethanol, and collected 40 % ethanol eluent, reclaiming ethanol to obtain solids as a 60% concentrated solution, vacuum-dried to obtain 17.5kg dry cream powder.

[0028] After testing, the content of rutin naringin in the obtained extract was 33.7%.

Abstract

The invention provides a process for extracting and purifying narirutin from bitter orange processing waste liquid. The process comprises the following steps: using bitter orange processing waste liquid as a raw material, and performing filtering with a ceramic membrane, macroporous adsorption resin chromatography, concentrating, macroporous adsorption resin chromatography, concentrating, vacuum drying, pulverizing and packaging. The method has the advantages that: the waste is turned into wealth, the purification pressure of a sewage treatment system can be effectively reduced, products witheconomic value are obtained, and human beings are benefited.

Description

technical field [0001] The invention relates to the field of separation and purification of effective components of Rutaceae plants, in particular to a process for extracting and purifying rutin naringin from bitter orange processing waste liquid. Background technique [0002] At present, natural plant active ingredients are widely used in medicine and food industries. Rutaceae naringin is a natural compound derived from the dried young fruit of Rutaceae lime, which has antibacterial, anti-inflammatory, anti-cancer, antispasmodic and choleretic effects . Rutinarin and EGCG have synergistic antioxidant effects. In the process of bitter orange processing to produce neohesperidin, rutin naringin is mainly enriched in the processing waste liquid, which has been treated as waste, which is a waste of resources. [0003] After retrieval, there is no method for extracting and purifying rutin naringin from bitter orange processing waste liquid. Contents of the invention [0004]...
