Extraction method and application of fructus foeniculi volatile oil

Abstract

The invention relates to the field of plant extraction, in particular to an extraction method and application of fructus foeniculi volatile oil. The extraction method disclosed by the invention is characterized in that volatile oil in fructus foeniculi fruits is extracted by adopting an ultrasonic two-step extraction method; the method has the advantages of being high in extraction rate, high in purity, short in extraction time, simple in operation steps, easy to operate, friendly to the environment and suitable for large-scale industrial production. The fructus foeniculi volatile oil extracted with the extraction method disclosed by the invention is used for a food preservative, and has the advantages of high antibacterial activity, good safety, good stability and wide antibacterial range; the fructus foeniculi volatile oil endows food with special flavor in sensory organ and also has bacteriostatic preservative functions, anti-oxidization and odor-correcting functions as well as physiological health-care functions.

Description

technical field [0001] The invention relates to the field of plant extraction, in particular to an extraction method and application of cumin volatile oil. Background technique [0002] Fennel, also known as Huaixiang, Huaixiangzi, Fennel, is a perennial herb with a special spicy taste throughout the plant, yellow flowers in summer, compound umbels. Fruit oval, yellow-green. Likes warm, suitable for sandy loam growth, avoid planting in clay and wet places. Cumin is an economic crop with "the same origin as medicine and food" in my country.

Cumin medicinal materials mainly contain sterols and glycosides, essential oils, alkaloids, amino acids and fatty oils, etc., as well as various types of compounds such as tannins, flavonoids, saponins, and triterpenes. It has the functions of dispelling cold and relieving pain, so it is often used to treat cold hernia and abdominal ...

AI Technical Summary

Problems solved by technology

[0003] The existing extraction methods of fennel volatile oil mainly include dilute sulfuric acid method, lime milk method, organic solvent method, liquid film method, water extraction method, etc., but there are problems such as low extraction rate, complicated operation, high solvent consumption, and easy environmental pollution.

[0004] At present, fresh-keeping technologies include freezing, radiation, modified atmosphere, high-pressure, microwave, vacuum packaging, ultrasonic, coating, adding preservatives, etc. The most commonly used chemical preservatives are: formic acid, acetic acid, propionic acid, Lactic acid, citric acid, ascorbic acid, sorbic acid, etc. With the wide application of chemical preservatives, people have gradually found that although the antibacterial effect of many chemical preservatives is relatively significant, they have certain influence and damage on the color and flavor of food. It has the function of carcinogenicity, carcinogenicity, teratogenicity, food poisoning and other problems. Long-term consumption will cause certain damage to the body and health. Therefore, it is necessary to find natural preservatives.
