Problems solved by technology

However, the current requirements for wolfberry extracts only use the polysaccharide components in wolfberry extracts as the quality index. Obviously, using such a simple and non-specific quality index is not enough to guarantee the quality of wolfberry deep-processed products

Embodiment 1

[0028] Weigh 10 kilograms 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 twice, the dosage is 80KG each time, each static extraction is 2 hours, and the extraction temperature is 80°C. The feed liquid obtained by leaching is filtered in situ. The combined extracts were filtered with a 0.1 μm fine filter membrane. The filtrate is treated with a 10000D ultrafiltration membrane to obtain two parts: the retentate after ultrafiltration and the pass through after ultrafiltration. The passing liquid after ultrafiltration is added and treated with a column volume of 1 molar sodium hydroxide solution, and then washed with pure drinking water by reverse osmosis to neutral OH - The column packed with ZB-2 strong basic anion exchange fiber is added at a flow rate of 1 column volume / hour. After adding the feed liquid, use reverse osmosis drinking pure water to wash t...

Embodiment 2

[0032]Weigh 10 kilograms of dried wolfberry fruit produced in Ningxia, rinse with reverse osmosis drinking pure water to remove floating dust. Extract twice with reverse osmosis drinking pure water, the dosage is 120KG each time, each static extraction is 1.5 hours, and the extraction temperature is 50°C. The feed liquid obtained by leaching is obtained by in-situ filtration. The combined extracts were filtered with a plate and frame filter and 0.1 kg of talcum powder was used as a filter aid. The filtrate is treated with a 5000D ultrafiltration membrane to obtain two parts: the retentate after ultrafiltration and the pass through solution after ultrafiltration. The passing liquid after ultrafiltration was added to the column filled with ZB-2 strongly basic anion exchange fiber treated into OHˉ type (treated according to the method of Example 1), and the flow rate was 1 column volume / hour. After adding the feed liquid, use reverse osmosis drinking pure water to wash the ion ...

Embodiment 3

[0034] Weigh 10 kilograms 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 twice, the dosage is 150KG each time, each static extraction is 3 hours, and the extraction temperature is 30°C. The feed liquid obtained by leaching is obtained by in-situ filtration. The combined soaking extracts were filtered with a 0.1 μm fine filter membrane. The filtrate is treated with an 8000D ultrafiltration membrane to obtain two parts: the retentate after ultrafiltration and the pass through after ultrafiltration. The passing liquid after ultrafiltration was added to the column filled with ZB-2 strongly basic anion exchange fiber treated into OHˉ type (treated according to the method of Example 1), and the flow rate was 1 column volume / hour. After adding the feed liquid, use reverse osmosis drinking pure water to wash the ion exchange column until the effluent is clear and...

Abstract

The invention discloses a wolfberry extract containing wolfberry acid. The wolfberry extract contains 1% to 10% of the wolfberry acid and 2% to 20% of wolfberry polysaccharide. The invention provides a preparation method which comprises the following steps: washing away the floating dust of a raw wolfberry material by using the reverse-osmosis drinking pure water; extracting the wolfberry in a soaking manner or a heating manner by using the reverse-osmosis drinking pure water; and carrying out filtration, adsorption, elution, ultrafiltration, concentration, sterilization, spraying and drying. According to the method, a new quality control point for the deep processing production of the wolfberry is provided, thereby offering help and support for improving the quality of a deep-processing wolfberry product and identifying the truth and the quality of the product, and has the far-reaching influence. Therefore, the wolfberry extract and the method provided by the invention are favorable for market purification and consumer benefit, thereby bringing benefit to human health. In addition, the method provided by the invention is suitable for industrial production, and has great application values and social benefits.

Description

technical field [0001] The invention relates to a plant extract, in particular to a preparation method of the plant extract, in particular to a wolfberry extract containing lycium chinense extracted from Lycium chinense and a method thereof. Background technique [0002] There are many foods that are beneficial to human health. However, wolfberry is a good plant health food, and its long history of clinical effectiveness is well known. The traditional definition of the function of wolfberry in China: the effect of nourishing liver and kidney, benefiting essence, building muscle, improving complexion, improving eyesight and calming nerves, dispelling wind and curing deficiency, prolonging life and strengthening bones and muscles. With the development of modern science, scientists have used advanced technology to reveal the material basis of the effectiveness of wolfberry. It is found to contain flavonoids, lycic acid, taurine, betaine and carotenoids, oligosaccharides, macro...
