Description

Technical Field

[0001] The invention relates to the technical field of grape ferns processing, in particular to a process for extracting sea grape oil from long-stem grape ferns. Background Art

[0002] As a unique marine plant, long-stemmed grape fern algae has attracted much attention because it is rich in various unsaturated fatty acids, vitamins, minerals and other nutrients. Sea grape oil is a precious oil extracted from long-stemmed grape fern algae. Due to its unique nutritional value and health care functions, it occupies an important position in the fields of food, health care products and cosmetics. As a key link in the production of sea grape oil, the performance of the extraction process has a decisive influence on the overall quality, yield and production efficiency of sea grape oil.

[0003] Especially in the core link of extracting sea grape oil from long-stemmed grape fern algae, the existing extraction process has gradually exposed a series of obvious limitations and technical problems when dealing with this marine plant with a specific shape and material. Specifically, the existing extraction process mainly uses traditional solvent extraction or pressing methods, which face many challenges in actual operation.

[0004] On the one hand, although the traditional solvent extraction method can extract sea grape oil, the extraction efficiency is relatively low, and a long extraction time and a large amount of solvent are required, which not only increases the production cost, but also may cause certain pollution to the environment. At the same time, the residual problem of solvent in the extraction process also affects the purity and safety of sea grape oil. On the other hand, although the pressing method is relatively simple to operate, it has high requirements on the crushing degree and pressing pressure of the long-stemmed grape fern algae, and it is difficult to achieve efficient oil extraction. In addition, the high temperature generated during the pressing process may also destroy the nutrients in the sea grape oil and reduce its quality. More seriously, the inefficiency of the existing extraction process directly leads to a decrease in the overall production efficiency of sea grape oil, an increase in the complexity of operation, and it is difficult to meet the needs of mass production. This not only significantly increases the production cost and risk, but also may bring potential risks to the market competitiveness and application value of sea grape oil. Therefore, in view of the many deficiencies in the existing technology, we urgently need an innovative process for extracting sea grape oil from long-stemmed grape fern algae to solve these problems. Summary of the invention

[0005] The purpose of the present invention is to provide a process for extracting sea grape oil from long-stem grape fern algae, which solves the problem that although the solvent extraction method in the prior art can extract sea grape oil, the extraction efficiency is relatively low, and a long extraction time and a large amount of solvent are required, which not only increases the production cost, but may also cause certain pollution to the environment.
