Problems solved by technology

Fagaceae plants grow in the mountains and forests all the year round, and the leaves grow in spring and fall in autumn. People mostly pay attention to the fruits of Fagaceae plants, but there are few researches and utilizations on the leaves with important medicinal value. Guo Shengmao et al. In 2006, a preliminary exploration was carried out on the variation of β-carotene content in Fagaceae leaves with seasons, but since then, no follow-up research has been carried out on the extraction and industrial application of β-carotene in Fagaceae leaves
But in fact, the leaves of Fagaceae plants contain a large amount of β-carotene, which is an excellent raw material for extracting β-carotene. If the extraction process is proper, the industrial value is immeasurable

Embodiment 1

[0026] A process for extracting natural beta-carotene, comprising the steps of:

[0027] (1) Cleaning: clean the collected leaves of the Fagaceae, remove the soil on the surface of the leaves, and remove impurities;

[0028] (2) wall-breaking treatment: the leaves of the Fagaceae plant after step (1) is cleaned and removed are subjected to wall-breaking treatment;

[0029] (3) Extraction: adding an organic solvent to the mixture obtained in step (2) for reflux extraction or ultrasonic extraction;

[0030] (4) centrifugation: the product of step (3) is centrifuged, the upper layer is an orange supernatant, and the lower layer is a filter residue;

[0031] (5) Evaporation: put the orange supernatant obtained in step (4) into an evaporator, and add ethanol to the evaporator to evaporate to obtain the crude product of β-carotene;

Abstract

The invention belongs to the technical field of beta-carotenes and relates to a method for extracting beta-carotenes, in particular to a method for extracting beta-carotenes from fagaceae plant leaves. The method comprises the following steps: (1) cleaning; (2) performing wall breaking treatment; (3) extracting; (4) performing centrifugal separation; (5) evaporating; (6) purifying to obtain a beta-carotene refined product; through detection, the purity of the prepared beta-carotenes is 90 percent or above. The processing process is simple and easy to implement, large in profit margin, convenient to popularize and very wide in market prospect.

Description

technical field [0001] The invention belongs to the technical field of beta-carotene, and relates to a method for extracting beta-carotene, in particular to a method for extracting beta-carotene from leaves of Fagaceae plants. technical background [0002] β-carotene is one of the carotenoids and is also an orange-yellow fat-soluble compound. It is the most stable and ubiquitous natural pigment in nature. β-carotene is currently widely used in food, feed additives, and cosmetic additives. In the past ten years, carotene has received unprecedented attention in the medical field, because many epidemiological investigations have shown that people who often ingest rich carotene in their diets have lower chances of suffering from diseases such as arteriosclerosis, certain cancers, and degenerative eye diseases. It is significantly lower than that of people who take in less carotene, and many animal experiments have also proved this point of view. For example, the vision of the ...
