Embodiment 1
[0014] (1) Crush and sieve: take 60 kg of orange core and crush it and pass it through a 10-16 mesh sieve.
[0015] (2) Extraction: Soak in 5 times the amount of 10% ethanol for two hours, extract for 1.5 hours, and extract twice.
[0016] (3) Concentration under reduced pressure: filter after extraction, concentrate under reduced pressure and filter the liquid, then centrifuge at 2000 rpm for 30 minutes, and extract about 35 liters of the middle layer of the clarified liquid. Add 4 times the amount of methanol, heat under stirring conditions for 30 minutes, condense and ethanol precipitation for 24 hours, extract the supernatant liquid, filter the precipitate under reduced pressure, combine the supernatant and filtrate, and dry the combined liquid under reduced pressure to obtain a dry cream About 2 kg.
[0017] (4) Resin adsorption: The present invention has investigated 10 kinds of resins including XAD series, LX series, HB series, ZSA series, etc., and found that ZSA-550 ...
Embodiment 2
[0023] (1) Crushing and sieving: take 120 kilograms of orange cores, pass through a 10-16 mesh sieve after crushing.
[0024] (2) Extraction: soak in 500 kg of 20% ethanol for two hours, and extract continuously for 1.5 hours.
[0025] (3) Concentration under reduced pressure: Concentrate the filtered solution under reduced pressure to 80 kg, then centrifuge at 2000 rpm for 30 minutes, and extract about 60 liters of the middle clarified liquid. Add 4 times the amount of methanol, heat under stirring conditions for 30 minutes, condense and ethanol precipitation for 24 hours, extract the supernatant liquid, filter the precipitate under reduced pressure, combine the supernatant and filtrate, and dry the combined liquid under reduced pressure to obtain a dry cream About 4 kg.
[0026] (4) Resin adsorption: The present invention has investigated 10 kinds of resins including XAD series, LX series, HB series, ZSA series, etc., and found that ZSA-550 resin has the best effect, which ...
