Embodiment 1

[0033] Take 5 kg of dried wolfberry fruit produced in Ningxia, rinse with reverse osmosis drinking pure water to remove floating dust. Use reverse osmosis drinking pure water to extract, the dosage is 50kg each time, after beating, statically extract for 1 hour, and the extraction temperature is 60°C. The material liquid extracted by immersion is filtered in situ. The combined extracts were filtered with a 0.1 μm fine filter membrane. The collected filtrate is concentrated in vacuum, (QN-300 spherical vacuum concentration), the vacuum concentration parameter is -0.093~-0.098 MPa 50~60. Concentrate to 6805g of solid content 35% liquid. Mix the concentrated feed solution evenly with 12kg of neutral chromatographic alumina (100-200 mesh), and send it to a digital blast drying oven for drying. The equipment model is GZX-9140MBE. The dry matter is pulverized in an equipment model of XL20B withholding and swinging pulverizer, and all pass through a 40-mesh sieve. Collect the sie...

Embodiment 2

[0036]Weigh 5 kg of dried fruit of Lycium barbarum produced in Ningxia, rinse with reverse osmosis drinking pure water to remove floating dust. Use reverse osmosis drinking pure water to extract, the dosage is 50kg each time, after beating, statically extract for 1 hour, and the extraction temperature is 60°C. The material liquid extracted by immersion is filtered in situ. The combined extracts were filtered with a 0.1 μm fine filter membrane. The collected filtrate is concentrated in vacuum, and the vacuum concentration condition is -0.093~-0.098 MPa 50~60. Concentrate to 7235g of solid content 34% liquid. Evenly mix the concentrated feed solution with 7.5kg of neutral chromatography silica gel (100-200 mesh), send it into a blast oven and dry it at 40°C for 48 hours, take out the dried material and pulverize it and pass it through a 40-mesh sieve. Collect the sieved material and add 63 kg of 85% ethanol and mix well to drive away the air bubbles to form a slurry. The slur...

Embodiment 3

[0039] Weigh 5 kg of dried fruit of Lycium barbarum produced in Ningxia, rinse with reverse osmosis drinking pure water to remove floating dust. Use reverse osmosis drinking pure water to extract, the dosage is 50kg each time, after beating, statically extract for 1 hour, and the extraction temperature is 60°C. The material liquid extracted by immersion is filtered in situ. The combined extracts were filtered with a 0.1 μm fine filter membrane. The collected filtrate is concentrated in vacuum, and the vacuum concentration condition is -0.093~-0.098 MPa 50~60. Concentrate to 6768g of solid content 36.2%. Evenly mix the concentrated feed liquid with 24.5kg of log fiber powder, send it into a blast oven and dry it at 40°C for 48 hours, take out the dried material and pulverize it and pass it through a 40-mesh sieve. Collect the sieved material and add 162 kg of 82% isopropanol and mix well to drive off the air bubbles to form a slurry, and pour the slurry into a chromatography...

Abstract

The invention provides a wolfberry fruit extract without low-melting-point impurities and dextrin. The wolfberry fruit extract without low-melting-point impurities contains 3-4% of lycium barbarum acid and 3-5% of lycium barbarum polysaccharide. The wolfberry fruit extract is prepared by the following steps: extraction, concentration, drying, packing and eluting, concentration, ultra-high-temperature sterilization, spray drying, etc. According to the wolfberry fruit extract provided by the invention, the low-melting-point impurities are removed, original active ingredients are selectively maintained, and the content of the active ingredients is increased. The invention provides a new product of deep processing of wolfberry fruits as well as the quality indexes of the new product, facilitates the production of wolfberry fruit extract products and is conducive to the interests of consumers and beneficial to human health. The method provided by the invention is suitable for industrial production and has great application value and important social benefits.

Description

technical field [0001] The present invention relates to a plant extract, in particular to a preparation method of the plant extract, in particular to a Lycium chinense extract from Lycium chinense, which is free of low melting point impurities, and a preparation method thereof. Background technique [0002] The inventor's "Lycium barbarum extract containing wolfberry acid and its preparation method" has obtained Chinese patent authorization CN103044569B. As we all know, Lycium barbarum is a kind of plant seed produced in Northwest China, which is nourishing, strong, medicinal and edible. It has high medicinal value and is rich in nutrients needed by the human body. From ancient times to the present, it has been regarded as a good medicine with special effects and the ability to resist fatigue and strengthen muscles and bones by Chinese medicine and folk. According to modern medical research, the active ingredients contained in it have proved that the carotenoids contained i...
