Embodiment 1

[0033] A preparation method of bitter gourd seed oil antibacterial fiber film, comprising the following steps:

[0034] S1. Crush the selected balsam pear seeds to 40 meshes, remove most of the balsam pear seed shells by sieving, and obtain the balsam pear seed powder raw material;

[0035] S2. Weigh 300g of processed bitter gourd seed powder raw materials, load into the extraction kettle of the low-temperature continuous phase change device, then insert high-purity n-butane, flow through the extraction kettle with a flow rate of 120L / h for extraction, and extract the bitter gourd After the seed oil is discharged, it flows into the analysis kettle. After decompression and heating, the extractant changes into gas and separates from the bitter melon seed oil. The extracted bitter gourd seed oil was stored at the bottom of the analysis kettle. After the extraction, the analysis kettle was released to recover n-butane. The extraction temperature was 50°C, the extraction pressure w...

Abstract

The invention belongs to the technical field of antibacterial nanofiber membrane preparation, and particularly relates to a balsam pear seed oil antibacterial fiber membrane and a preparation method thereof. According to the invention, balsam pear seed oil obtained through low-temperature continuous phase change extraction of balsam pear seeds is taken as a research object, and the balsam pear seed oil is embedded in a nanofiber membrane by utilizing the antibacterial function of effective components of the balsam pear seed oil and combining a modern electrostatic spinning technology, so that an antibacterial material which has the characteristics of a nanostructure and contains a natural antibacterial agent is formed. The balsam pear seeds are extracted with n-butane in a low-temperature closed environment, on the basis, the advantages of a natural antibacterial agent and a high polymer with high biocompatibility are combined, the antibacterial film which takes polyvinyl alcohol as a wall material and loads balsam pear seed oil is prepared through electrostatic spinning, and the antibacterial film is excellent in antibacterial performance.

Description

technical field [0001] The invention belongs to the technical field of preparation of antibacterial nanofiber membranes, and particularly relates to an antibacterial fibre membrane of balsam pear seed oil and a preparation method thereof. Background technique [0002] Bitter gourd is the fruit of bitter gourd, a genus of cucurbitaceae, known as a "medicinal vegetable" and has strong pharmacological activity. At present, flavonoids, proteins, organic acids, saponins and alkaloids have been isolated from the fresh fruits of bitter gourd, and it has been found that bitter gourd has the functions of lowering blood sugar, lowering blood lipids, anti-virus and anti-cancer. Bitter melon has been developed into a variety of functional foods, such as bitter melon beverages, herbal tea, ice cream, canned food, etc., and has also been used as a health food to assist hypoglycemics. . [0003] Bitter melon seeds, namely bitter melon seeds, contain a variety of bioactive components in t...
