Embodiment 1

[0022] Embodiment 1: A method for extracting proanthocyanidins from seabuckthorn seeds with high efficiency and high pressure difference at room temperature, comprising the following steps:

[0023] 1) Weigh the supercritical CO 2 After extracting seabuckthorn oil, 5kg of seabuckthorn seed meal was crushed to 50-80 mesh coarse powder, soaked in 50kg of 40% ethanol for 0.5 hours, extracted once at a pressure of 22Mpa using a high pressure differential device, and filtered with a 300 mesh filter cloth to obtain a filtrate of 38kg.

[0024] 2) Use low temperature (20-25°C) negative pressure (-0.098Mpa) heat pump concentration device to recover ethanol from 38kg of extract and concentrate the extract into 1.62kg of proanthocyanidin extract.

[0025] 3) Dry 1.62kg of proanthocyanidin extract with low temperature (25-30°C) negative pressure (-0.098Mpa) belt drying device to obtain 0.78kg of seabuckthorn seed proanthocyanidin extract powder with a proanthocyanidin content of 48.5%. ...

Embodiment 2

[0026] Embodiment 2: A method for extracting proanthocyanidins from seabuckthorn seeds with high efficiency and high pressure difference at room temperature, comprising the following steps:

[0027] 1) Weigh the supercritical CO 2 After extracting seabuckthorn oil, 10kg of seabuckthorn seed meal was crushed to 50-80 mesh coarse powder, soaked in 150kg of pure water for 0.5 hour, extracted twice under a pressure of 25Mpa using a high pressure differential device, and filtered with a 300 mesh filter cloth to obtain 125kg of filtrate.

[0028] 2) Concentrate 125kg of the extract into 3.5kg of proanthocyanidin extract using a low temperature (30°C) negative pressure (-0.098Mpa) heat pump concentration device.

[0029] 3) Dry 3.5kg of proanthocyanidin extract with low temperature (30°C) negative pressure (-0.098Mpa) belt drying device to obtain 1.60kg of seabuckthorn seed proanthocyanidin extract powder, with a proanthocyanidin content of 40.5%.

Abstract

The invention relates to a method of continuously extracting procyanidine of seabuckthorn seeds efficiently with high pressure difference at room temperature. The method comprises the following step of carrying out extraction at room temperature: 10-40 DEG C, wherein the solvent is water or ethanol, concentration of ethanol is 10-60%, the slurry-liquid ratio is 1: 8 to 1: 30 and the pressure difference value is -0.1 to 50 Mpa. The method is low in temperature of a production process, is used for extracting procyanidine continuously instantaneously, is energy-saving and environment-friendly, high in production efficiency, high in procyanidine extraction rate, free of solvent residues and high in product quality, and meets the demands in various procyanidine health care products, special medical food and drug development.

Description

Technical field: [0001] The invention relates to a low-temperature and high-efficiency method for extracting proanthocyanidins from seabuckthorn seeds. Background technique: [0002] In the middle of the 20th century, French scientist Masquel first discovered proanthocyanidins in plants. After nearly 60 years of research, people's understanding of the health-care pharmacological effects of plant proanthocyanidins has been continuously improved. In recent years, a large number of studies have confirmed that proanthocyanidins are not only an efficient antioxidant, but also can regulate key biological pathways in the human body and participate in many redox chain reactions in basic life processes. Studies have confirmed that oligomeric proanthocyanidins have direct or indirect preventive and therapeutic effects on nearly a hundred kinds of injuries and diseases in the body, and are widely used in the fields of health care products, food for special medical purposes, standard d...
