Abstract

The invention discloses a Litsea cubeba essential oil nanoemulsion. The Litsea cubeba essential oil nanoemulsion is prepared by compounding an aqueous phase and an organic phase containing Litsea cubeba essential oil, the mass ratio of the Litsea cubeba essential oil to the organic phase is (0.5-2):1, and the mass ratio of the organic phase to the aqueous phase is (0.15-0.25):1. The Litsea cubebaessential oil nanoemulsion solves the problem that Litsea cubeba essential oil serving as an oily substance is insoluble in the aqueous phase, has good low-temperature stability and strong antibacterial and antioxidant properties, can inhibit decay and quality maintenance of aquatic products and prolong the shelf life of the aquatic products, and has a wide application prospect in the field of preservation and corrosion prevention in the cold preservation process of the aquatic products.

Description

technical field

[0001] The invention relates to a litsea cubeba essential oil nanoemulsion. Background technique

[0002] In the process of food processing, storage, and distribution, spoilage and deterioration are caused by oxidation and harmful microorganisms. In order to maintain the nutritional value and quality of food, the traditional preservation methods for aquatic products include physical processing and chemical synthesis of antibacterial agents, but there are potential safety hazards. . Among them, the cost of physical processing technology and equipment is high and it is easy to cause damage to food nutrients; chemical antibacterial agents such as chemical compounds and antibiotics are likely to cause safety hazards such as bacterial resistance, and excessive intake will cause potential harm to human health.

[0003] Plant essential oils are highly concentrated extracts of aromatic plants, which can be obtained from the flowers, leaves, stems, roots, fruits, see...
