Embodiment 1

[0015] Example 1: Preparing sago polyphenols with sago peel residue as raw material.

[0016] Get 80 mesh dry sand fruit peel residues, in an ultrasonic extractor, extract sand fruit polyphenols under 250W ultrasonic power, the extraction solvent is 50% ethanol, the extraction time is 30min, the extraction temperature is 50°C, the ratio of solid to liquid is 1:5, and the extraction time is 2 Second-rate. Collect the leach liquid and concentrate it initially.

[0017] Separation and purification adopt the AB-8 macroporous resin column chromatography method, adopt wet packing (1.0 × 40cm), column bed height 30cm, add the leaching solution of sargo polyphenols at a flow rate of 1mL / min, after adsorption saturation, use 2

[0018] BV (column bed volume) was washed with distilled water to remove impurities such as sugar and water-soluble hemicellulose adsorbed by the resin. Then, it was eluted with 60% ethanol solution until it was colorless, and the elution flow rate was 0.5 mL / ...

Embodiment 2

[0020] Example 2: Preparing sago polyphenols with sago peel residue as raw material.

[0021] Get 100 mesh dry sand fruit peel residues, in an ultrasonic extractor, extract the sand fruit polyphenols under the ultrasonic power of 250W, the extraction solvent is 60% ethanol, the extraction time is 25min, the extraction temperature is 55°C, the ratio of solid to liquid is 1:8, and the extraction time is 25 minutes. Second-rate. Collect the leach liquid and concentrate it initially.

[0022] Separation and purification are the same as in Example 1.

[0023] The obtained eluate is concentrated by rotary evaporation at a vacuum degree of 0.09MPa and an evaporation temperature of 55°C, and then vacuum-dried at a vacuum degree of 0.09MPa and a temperature of 55°C to obtain sargopolyphenol powder, which has a content of sagopolyphenols of 72%. .

Embodiment 3

[0024] Example 3: Preparing sago polyphenols with sago peel residue as raw material.

[0025] Take 80 mesh dry sand fruit peel residues, in an ultrasonic extractor, extract sand fruit polyphenols under 250W ultrasonic power, the extraction solvent is 75% ethanol, the extraction time is 30min, the extraction temperature is 50°C, the ratio of solid to liquid is 1:10, and the extraction time is 1 Second-rate. Collect the leach liquid and concentrate it initially.

[0026] Separation and purification are the same as in Example 1.

[0027] The obtained eluate is concentrated by rotary evaporation at a vacuum degree of 0.075MPa and an evaporation temperature of 55°C, and then vacuum-dried at a vacuum degree of 0.09MPa and a temperature of 50°C to obtain sargopolyphenol powder, and its content of sagopolyphenols is 80%. .

Abstract

The invention relates to a method for extracting crabapple polyphenols from crabapple skin dregs, which comprises the procedures of soaking of the dried and smashed crabapple skin dregs in ethanol solution, ultrasonic extraction, column chromatography separation and purification, rotary evaporation concentration, vacuum drying and the like, wherein, the polyphenols are extracted from the crabappleskin dregs soaked in the ethanol solution in an ultrasonic extraction device, the ultrasonic power is 250W, and the AB-8 macroporous resin column chromatography method is adopted for separation and purification. The crabapple polyphenols are powder products, and the content of the polyphenols is 65%-80%. Raw materials used for extracting the crabapple polyphenols by adopting the method are the crabapple skin dregs, thereby not only utilizing wastes, but also reducing environmental pollution; and the method has the advantages of time-saving property, energy conservation, high extraction rate of the polyphenols and no solvent residue, and can greatly improve the additional value and the comprehensive utilization efficiency of agricultural and sideline products. The method can solve the problems of long extraction time and low purity of the conventional method, and is easy to realize the industrial production.

Description

1. Technical field [0001] The invention relates to the development and utilization of sand fruit peel residue, in particular to a method for extracting and preparing sand fruit polyphenols by using sand fruit peel residue as a raw material in the production process of sand fruit concentrated juice. 2. Background technology [0002] Shaguo pomace is a by-product in the processing of Shaguo juice, which is rich in polyphenols. At present, a large amount of pomace in the processing of shaguo concentrated juice is discarded as garbage, which not only wastes resources but also pollutes the environment. Sargolin, as a class of biologically active natural compounds, plays a pivotal role in human health. Many studies have shown that polyphenols have a variety of health functions, such as preventing dental caries, preventing high blood pressure, anti-tumor, anti-mutation, antibacterial, scavenging free radicals, anti-oxidation and anti-aging, etc., especially its anti-oxidation abil...
