Problems solved by technology

In the prior art, there is also research on extracting pectin from the seeds of the Fructus Lily, but in the application and research of the Fructus Lily, it is mainly concentrated on the seeds of the Fructus Lily, while the perianth rich in pectin is discarded, causing a lot of problems. big waste of resources
It can be seen that it is of great significance to study the extraction of pectin from the perianth of Sapphire lily, and there is no patent report related extraction method at home and abroad.

Embodiment 1

[0013] The Ficus pumila flower was crushed to 0.5cm pericarp, rinsed in water at 70℃ for 20min, filtered and dried in an oven at 70℃. Weigh 150g of dried Ficus pumila quilt, add 20 times the weight of water to mix, adjust pH to 1.0 with acid, heat to 85°C, fully stir for 80min, filter through plate and frame filter press to obtain filtrate. 0.3% (w / v) activated carbon was added to the filtrate, stirred at 65°C for 20 minutes, and filtered to remove the activated carbon after decolorization. Add 1.5 to 2.0 times the volume of 95% edible ethanol to the decolorized pectin extract for precipitation, centrifuge (rotation speed is 4800r / min), the filter residue obtained after centrifugation is washed with dilute alcohol, and vacuum dried at 48°C for 4 hours , Then take out the pectin product which is crushed and sieved, and the filtrate is processed for ethanol recovery.

Embodiment 2

[0015] The Ficus pumila flower was crushed to 0.5cm pericarp, rinsed in water at 70℃ for 20min, filtered and dried in an oven at 70℃. Weigh 200g of dried Ficus pumila quilt, add 25 times the weight of water to mix, adjust pH to 1.0 with acid, heat to 85°C, fully stir for 80min, filter by plate and frame filter press to obtain filtrate. 0.3% (w / v) activated carbon was added to the filtrate, stirred at 65°C for 20 minutes, and filtered to remove the activated carbon after decolorization. Add 1.5 to 2.0 times the volume of 95% edible ethanol to the decolorized pectin extract for precipitation, centrifuge (rotation speed is 5000r / min), the filter residue obtained after centrifugation is washed with dilute alcohol, and vacuum dried at 50℃ for 4.5h , Then take out the pectin product which is crushed and sieved, and the filtrate is processed for ethanol recovery.

Embodiment 3

[0017] The Ficus pumila flower was crushed to 0.35cm pericarp, rinsed in 70℃ water for 20min, filtered and dried in an oven at 70℃. Weigh 300 g of dried Ficus pumila quilt, add 15 times the weight of water and mix, adjust the pH to 1.0 with acid, heat to 90°C, fully stir for 100 min, filter through a plate and frame filter press to obtain the filtrate. 0.35% (w / v) activated carbon was added to the filtrate, stirred at 60°C for 25 minutes, and filtered to remove the activated carbon after decolorization. Add 1.5-2.0 times the volume of 95% edible ethanol to the decolorized pectin extract for precipitation, centrifugation (rotating speed 5500r / min), the filter residue after centrifugation is washed with dilute alcohol, and vacuum dried at 55°C for 5h. Then the pectin product is obtained by pulverizing and sieving, and the filtrate is subjected to ethanol recovery treatment.

Abstract

he invention relates a method to extract a low ester pectin from a ficus pumila perianth, which uses the ficus pumila perianth as the raw material, which is rinsed by hot water and dried, then is carried on leaching by acids, filtration, discoloration, alcohol precipitation, centrifugalization, vacuum drying and grinding, so that a pectin is obtained, wherein, the ficus pumila perianth is crushed, then rinsed by hot water to be discolored; the extracting solution is filtered and processed by active carbon and alcohol precipitation. The invention has the advantages of less process, simple equipment, etc., is characterized in that the production rate of the low ester pectin prepared is high, and has a shallow color, and the indictors of the low ester pectin are met or exceeded national newest industry procession standard (QB2482-2000).

Description

Technical field [0001] The invention relates to a method for extracting low-ester pectin from the quilt of Ficus pumila. Background technique [0002] Xue Li belongs to the genus Ficus of the Moraceae family, also known as jelly tree, wooden steamed bun, etc. It is widely distributed in the south of the Yangtze River in my country to Guangdong, Jiangxi and other provinces. From the herbal records, Ficus pumila has a long medicinal history, and its roots, stems, vines, leaves and fruits can all be used as medicine. In addition, it is better to use Ficus pumila fruit in combination with other medicines to treat some cancers. Ficus pumila not only has high medicinal value, but also has a very comprehensive nutritional value. Studies have shown that Ficus pumila pollen contains 39.88% protein, 18.83% total sugars, 8.88% reducing sugars, 1.46% fat and 1.46% total flavonoids. The perianth pectin content of Ficus pumila achenes is 20-32.70%, the protein content is 3.80%, and the total f...
