Problems solved by technology

[0003] At present, the most commonly used microcapsule technology in the food industry is the spray drying method, but the microcapsules prepared by the spray drying method are very unstable under high temperature and high humidity processing or storage conditions, and the glassy capsule wall is very easy to absorb water, swell and break , resulting in the release of the core material, which cannot protect the turmeric essential oil well and exert its long-term antibacterial effect

Abstract

The invention discloses a preparation method of a high-temperature resistant microencapsulation turmeric essential oil biological bacteriostatic agent, which comprises the following steps of: dissolving gelatin and peach gum in a wall material to obtain a wall material solution; adding turmeric essential oil into the wall material solution, and emulsifying and dispersing at high speed to obtain emulsion; and stirring the emulsion in a constant temperature waterbath, regulating a pH value by using acetic acid, performing complex coacervation reaction, and forming microcapsule suspension liquid; cooling, regulating the pH value by using NaOH solution, adding glutamine transaminase, solidifying, leaching, drying, and thus obtaining turmeric essential oil microcapsule. The wall material is available, and the turmeric essential oil microcapsule has stable quality, is low in cost, and is safe to eat. The turmeric essential oil microcapsule has characteristic of controlling releasing in high-temperature and high-humidity environments, and turmeric essential oil has an effect of resisting bacteria in a high-temperature environment.

Description

technical field [0001] The invention belongs to the field of food engineering, and in particular relates to a preparation method of a high-temperature-resistant microencapsulated turmeric essential oil biological antibacterial agent. Background technique [0002] The main components of turmeric essential oil are curcumone, dehydroturmerone, phellandrene, camphor, curcumone, curcumedione, curcumenol, curcumene, zingiberene and eucalyptol. The biological activity of turmeric essential oil is mainly as follows: (1) It can inhibit bacteria, parasites, and pathogenic fungi to varying degrees; (2) It has excellent anti-inflammatory activity, which can inhibit early and late inflammation; (3) It has obvious effect on tumors. (4) has anthelmintic effect; (5) has anti-mutation effect, which can not only protect cells from damage, but also promote DNA repair of mutated cells. However, turmeric essential oil is highly volatile, and the volatile components are mainly monoterpenoids, se...
